**Short answer:** To create a Call of Cthulhu 7e investigator, roll STR, CON, DEX, APP, and POW on 3D6 x 5 and SIZ, INT, and EDU on (2D6+6) x 5, apply one age band, then work out hit points, magic points, Sanity, and Luck. Choose an occupation, spend its skill points (including Credit Rating), spend INT x 2 personal-interest points, and write three to six backstory entries with one starred key connection. Pre-generated investigators skip the arithmetic but still need a personal hook.

## Introduction

This guide walks through building a Call of Cthulhu 7e investigator from blank sheet to first scene. It covers rolling characteristics, calculating play values, choosing an occupation, and spending skill points. It also covers writing a backstory with a key connection and, when time is short, adapting a pre-generated investigator so it still feels like yours.

## Hot Take

An investigator with a sharp reason to engage the scenario and a useful noncombat way into scenes is a better first character than an optimized stat spread with no connection to the mystery. Call of Cthulhu does not reward a character sheet that tries to win every confrontation. It rewards a person whose occupation, relationships, skills, and personal stakes give the Keeper several honest ways to put the investigation in front of them.

Numbers still matter. They decide what an investigator can plausibly attempt and how often a risky roll succeeds. But the choices that hold up make failure productive: a reporter can press a reluctant source, a physician can recognize what should not be medically possible, and a well-connected dilettante can open doors that a lockpick cannot. The same logic applies to backstories and pregens. The best backstory is a handful of facts you want to see tested, not a tragic novel, and the only bad pregen is one handed to a player with no reason to care. Build the person first, then choose numbers that make that person credible.

## The Best Investigator Is Ready To Investigate

The best Call of Cthulhu investigator is the person who has a reason to care about the opening problem, credible ways to enter scenes, and enough personality for the consequences to matter.

That is the central character-creation test: when the Keeper describes the first strange event, can you explain why this person investigates instead of going home? A low Strength score does not fail that test. Neither does an unconventional occupation. An investigator fails it only when they have no connection, no curiosity, and no reason to take the next lead.

Create characters with the Keeper and the other players when possible. The process works best as a group conversation: everyone can align with the era, location, premise, and campaign assumptions while avoiding a party of investigators who all solve the same problem in the same way.

## Character Creation At A Glance

| Step                        | Mechanical job                                                            | Story job                                                        | Do not skip this                                         |
| --------------------------- | ------------------------------------------------------------------------- | ---------------------------------------------------------------- | -------------------------------------------------------- |
| 1. Generate characteristics | Establish the eight characteristics, Luck, and age modifiers.             | Decide what the results mean for a real person.                  | Keep low scores as useful texture.                       |
| 2. Derive play values       | Record Sanity, magic points, hit points, Damage Bonus, Build, and MOV.    | Note what the body and mind can take.                            | Check each value once, then move on.                     |
| 3. Choose an occupation     | Identify professional skills, Credit Rating, and occupation skill points. | Establish access, status, routines, and contacts.                | Ask how the job opens the first lead.                    |
| 4. Allocate skills          | Spend occupation points, then INT x 2 personal-interest points.           | Show expertise and life outside work.                            | Cover at least one way to find or interpret information. |
| 5. Create a backstory       | Write three to six entries and star a key connection.                     | Give the Keeper people, places, beliefs, and possessions to use. | Make one connection relevant immediately.                |
| 6. Finances and equipment   | Look up cash, assets, and spending level from Credit Rating; note gear.   | Decide what this person reasonably carries and can obtain.       | Pack for the premise, not for a dungeon.                 |

The sheet is a play aid, not a biography contest. Fill in enough to make decisions easy during play, then leave room for the investigator to change as the campaign gives them scars, allies, fears, and hard-won knowledge.

## Start With The Campaign

Before rolling anything, ask the Keeper four questions:

1. What era and location does the game use?
2. What is the initial premise or type of scenario?
3. Are any occupations, backgrounds, or sources off-limits or especially useful?
4. How do the investigators know each other or come to trust one another?

A Keeper can answer all of that without giving away the mystery, and the answers are what let you make a character who belongs in the story. An academic expedition, a city investigation, and a rural family mystery call for different reasons to be present. A concert violinist can be a superb investigator, but needs a plausible route into an isolated mining town or a reason to care about the missing surveyor.

Write a one-sentence premise tie before you touch skill points. Examples:

- "My colleague vanished after asking me to authenticate a diary."
- "The victim was my sister's employer, and the police have dismissed her concerns."
- "I was hired to inventory the estate, but I recognize the family name from an old case."

This gives the Keeper something to work with and gives you a reason to choose the next lead even when it becomes dangerous.

## Choose A Character Method

The default method rolls the eight characteristics, applies one set of age modifiers, and derives the values the sheet needs. The Keeper Rulebook also lists optional methods, and the Keeper picks which ones the table uses.

| Method                      | How it works                                                                                                      | Watch for                                                                          |
| --------------------------- | ----------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------- |
| Default rolling             | Roll each characteristic in order.                                                                                | Do not discard a character merely because one characteristic is low.               |
| Start over                  | Scrap the rolls and begin again; the book suggests allowing it when three or more characteristics start below 50. | Agree on the trigger before anyone rolls.                                          |
| Modify low rolls            | Roll an extra 1D6 and share its points among the lowest dice before multiplying by 5.                             | Only when several rolls are very low.                                              |
| Choose where rolls go       | Roll five 3D6 and three 2D6+6, multiply by 5, and assign them freely.                                             | The book recommends at least 40 in INT and SIZ.                                    |
| Point buy                   | Share 460 points among the eight characteristics, each between 15 and 90.                                         | Same INT and SIZ recommendation.                                                   |
| Quick fire                  | Assign 40, 50, 50, 50, 60, 60, 70, 80, then set occupation skills directly to 70, 60, 60, 50, 50, 50, 40, 40, 40. | Fast, but still add a personal hook.                                               |
| Pre-generated investigators | Take a finished sheet from a scenario, the Investigator Handbook, or the Keeper.                                  | See [Use Pre-generated Investigators Well](#use-pre-generated-investigators-well). |

In the quick-fire method, those nine values cover the eight occupation skills plus Credit Rating, and you add 20 points to four non-occupation skills. Choose the method that makes the table excited to play these people. A character with an imperfect spread and a strong hook is usually more useful than a polished collection of scores with no reason to engage the scenario.

## Read Characteristics As Story Prompts

Call of Cthulhu uses eight characteristics. Under the default method, roll 3D6 and multiply by 5 for STR, CON, DEX, APP, and POW, and roll 2D6+6 and multiply by 5 for SIZ, INT, and EDU. That gives the three "learned or built" characteristics a floor of 40.

| Characteristic | Roll        | What it broadly represents               | A useful character question                               |
| -------------- | ----------- | ---------------------------------------- | --------------------------------------------------------- |
| STR            | 3D6 x 5     | Physical force.                          | What work, habit, injury, or training explains this?      |
| CON            | 3D6 x 5     | Health and resilience.                   | How does this person handle exhaustion, illness, or pain? |
| SIZ            | (2D6+6) x 5 | Height and weight combined.              | How does their build affect how others see them?          |
| DEX            | 3D6 x 5     | Quickness and fine control.              | Are they steady, athletic, practiced, or awkward?         |
| APP            | 3D6 x 5     | Presence and outward impression.         | What makes a first impression memorable?                  |
| INT            | (2D6+6) x 5 | Learning, analysis, and problem solving. | What patterns do they notice before others do?            |
| POW            | 3D6 x 5     | Will, drive, and magical potential.      | What keeps them going when fear says stop?                |
| EDU            | (2D6+6) x 5 | Retained formal and factual knowledge.   | Where did they learn what they know?                      |

Do not treat INT and EDU as the same thing. A highly educated person may have a great store of learned facts but poor judgment in a novel situation. A person with little formal education can still be perceptive, inventive, and exceptionally capable. That tension is character material, not a defect to smooth away.

Low characteristics also create useful constraints. A frail professor may recruit help before entering a hostile place. A socially awkward mechanic may be excellent at reading an engine but terrible at convincing a clerk. Those limits make the party matter and tell you how the investigator solves problems.

## Calculate The Play Values

Once characteristics and age modifiers are final, record the values that drive play. The sheet gives space for full, half, and fifth values because the game calls for Regular, Hard, and Extreme results. Calculate those now so a tense roll does not turn into arithmetic.

| Value                  | Comes from                                                   | Why it matters in play                                               |
| ---------------------- | ------------------------------------------------------------ | -------------------------------------------------------------------- |
| Sanity                 | Begins equal to POW.                                         | Establishes the investigator's initial mental resilience.            |
| Magic points           | One-fifth of POW.                                            | Tracks the resource used by magic.                                   |
| Hit points             | CON plus SIZ, divided by 10 and rounded down.                | Tracks physical harm and endurance.                                  |
| Damage Bonus and Build | STR plus SIZ, looked up on the rulebook table.               | Matter in hand-to-hand combat, maneuvers, scale, and chases.         |
| Movement rate          | STR, DEX, and SIZ compared, then reduced from age 40 onward. | Matters when movement and pursuit become important.                  |
| Luck                   | A separate 3D6 x 5 roll.                                     | Handles circumstances external to the investigator's direct control. |

As a worked example, the rulebook's sample investigator has POW 45, so he starts with 45 Sanity and 9 magic points. Use the sheet and the rulebook's quick reference for half and fifth values, check each result once, and move on to the choices that define play. The [Characteristics Guide](/articles/coc-7e/character-creation/characteristics) and [Luck Guide](/articles/coc-7e/character-creation/luck) cover these values in more depth.

## Choose An Occupation For Access

An occupation is more than a list of skills. It tells the table where the investigator belongs before the horror begins. A journalist can ask questions and publish inconvenient facts. A doctor can enter medical spaces and recognize injuries. A laborer may know the physical rhythms of a site that an academic overlooks. A socialite can belong in rooms where other investigators attract attention.

Choose an occupation using three questions:

1. **What can this person plausibly access?** Think records, institutions, neighborhoods, tools, witnesses, and professional peers.
2. **What can they contribute to an investigation?** A role can contribute research, observation, language, social pull, practical work, or physical protection.
3. **Why are they involved now?** Connect the job to the premise, a contact, a debt, an old interest, or a current risk.

Each occupation names a skill-point formula, eight occupation skills, and a Credit Rating range. The Keeper Rulebook's Journalist, for example, uses EDU x 4 and a Credit Rating range of 9 to 30, so an investigator with EDU 84 has 336 occupation points. Spend them on the listed skills, and put enough into Credit Rating to land inside the range. Personal-interest points equal INT x 2 and can go into any skill, including occupation skills, except Cthulhu Mythos unless the Keeper agrees.

Do not choose a job only because it appears to cover the most useful skills. The most effective occupation is one you can repeatedly bring into scenes. The [Occupations Guide](/articles/coc-7e/character-creation/occupations) compares formulas, Credit Rating ranges, and the best occupation families for different campaigns.

## Spend Skill Points For A Real Person

Allocate occupation points first. Then use personal-interest points to answer the question, "What does this person care about when they are off the clock?" That second pool is where a detective's amateur archaeology, a professor's competent firearms training, or a dockworker's unexpected language study can become a believable lead into the scenario. The rules note that, outside a few occupations such as Soldier, extra Fighting and Firearms points usually come from this pool.

Add points to the base chance printed on the sheet and write down the total. Fill in half and fifth values only after both pools are spent, because personal-interest points can raise occupation skills too.

Use this distribution check before finalizing the sheet:

- **One professional strength:** a skill or cluster that the investigator can credibly lead with.
- **One information route:** research, observation, social inquiry, technical examination, language, or another way to uncover facts.
- **One pressure response:** a way to deal with danger, escape, concealment, persuasion, or practical obstacles.
- **One personal interest:** a skill that reveals a life beyond the occupation and can surprise the table.
- **One deliberate gap:** something the investigator cannot do well, leaving room for another investigator or an interesting complication.

Broad coverage across the party is more important than every individual being self-sufficient. A group that can notice clues, research evidence, talk to people, and respond when danger arrives has more options than a group built around one repeated solution.

## Write A Backstory The Keeper Can Use

The notes on the back of the investigator sheet are part of the game, not decoration. The Keeper Rulebook gives them three jobs: a quick roleplaying guide, a source of Sanity recovery during the investigator development phase, and a record that changes as the investigator suffers injuries, madness, and contact with the Mythos.

That makes a useful backstory different from a detailed chronology. A five-page account of childhood may be enjoyable to write, but it is hard to use when the Keeper asks what the character does after finding a body in a locked room. A short entry such as "My sister Ruth, who believes I abandoned her" creates a choice on the spot. Do you call her? Hide the truth? Ask for help? Refuse to risk her?

Every entry should tell the table at least one of these things:

| It can tell the table          | Example question it answers                                  |
| ------------------------------ | ------------------------------------------------------------ |
| What the investigator values   | What would they protect when the situation turns ugly?       |
| Where they belong              | Who recognizes them, and which doors are familiar?           |
| Why they have a skill or habit | What made them learn this, and what does it cost them?       |
| What pressures them            | What can make a reasonable person take an unreasonable risk? |
| What can change                | How will the horror leave a mark after the scene ends?       |

The goal is not to make the character miserable before play begins. Cosmic horror works because it disrupts a life that had ordinary attachments, routines, ambitions, and assumptions. Give your investigator something real before you ask what the Mythos can take away.

### The Six Starting Categories

The rules ask for three to six short entries across six categories: Personal Description, Ideology/Beliefs, Significant People, Meaningful Locations, Treasured Possessions, and Traits. You do not need one in every category. The other boxes on the sheet (Injuries and Scars, Phobias and Manias, tomes and spells, Encounters with Strange Entities) are filled in during play. Write one or two sentences per entry so the notes stay readable mid-game.

| Category              | Weak entry     | Playable entry                                                                        |
| --------------------- | -------------- | ------------------------------------------------------------------------------------- |
| Personal Description  | "Well dressed" | "Well dressed because appearing poor terrifies him."                                  |
| Ideology/Beliefs      | "Science."     | "No ghost has ever survived a proper explanation, and I intend to prove it."          |
| Significant People    | "A brother."   | "Elias, my older brother, a police sergeant who thinks I exaggerate every danger."    |
| Meaningful Locations  | "The library." | "The basement stacks of the county library, where I worked nights during university." |
| Treasured Possessions | "A watch."     | "My father's repaired watch, stopped at the hour he died."                            |
| Traits                | "Brave."       | "I speak too confidently when I am afraid."                                           |

**Personal Description.** Pick a detail another person notices quickly: ink-stained hands, an old army coat altered to fit, an overly careful manner, a limp that worsens in cold weather. It gives you a consistent first beat when entering a scene. An appearance detail is not a personality, so attach a pressure when you can.

**Ideology or Beliefs.** Choose a conviction with consequences: faith, scientific certainty, a political cause, spiritualism, family obligation, a commitment to justice, or a private superstition. "I promised my dying mother I would never miss Sunday service" gives the Keeper a tone to push against and gives you a reason to react when the evidence turns impossible.

**Significant People.** Name at least one person and say why the relationship matters. They can be beloved, feared, resented, admired, depended upon, or avoided. A former supervisor who knows too much or a mentor whose approval still matters is more useful than a helpless dependent. Give the person a location, a role, and one boundary: "Dr. Eleanor Vale, my former lecturer, works at the university and will help with research but will never cover for a lie."

**Meaningful Locations.** Pick a place with emotional or practical weight: a childhood street, workshop, parish, boarding house, veterans' club, cafe, or family plot. It works best when it explains how the investigator knows part of the setting. Keep it ordinary. An ordinary place becomes powerful when the campaign makes it unfamiliar.

**Treasured Possessions.** Choose something whose loss would mean more than its market value, and state the connection. The object need not be magical, cursed, or mechanically useful.

**Traits.** Traits are quick instructions for difficult decisions. Pick a tendency that can help and complicate play: refuses to leave a question unanswered, never insults a host, cannot bear to disappoint children, counts exits in every room. Choose behavior, not a diagnosis or a blank adjective.

### Pick A Key Connection

After writing your entries, star or underline the one that matters most. The rules call it the key connection: the one thing above all else that gives the investigator's life meaning.

It carries a limited protection. The Keeper can use it, threaten it, and change the world around it, but cannot destroy, kill, or take it away without first giving the player a chance to roll dice to save it. That is a promise of agency, not immunity. If it is lost anyway, the investigator makes a Sanity roll (1/1D6). Only the player can change the key connection, and only during the investigator development phase.

It also matters for recovery. When an investigator uses the key connection for self-help Sanity recovery, the player gets a bonus die on the Sanity roll. Success restores 1D6 Sanity and also cures any indefinite insanity. Failure revises that part of the backstory, and the investigator no longer has a key connection until a later self-help success converts another entry, or a Sanity roll of 01 lets the player name a new one.

Choose carefully. "My family" is too broad to play. "My younger brother Samuel, who still sends me letters from the farm" gives the table a person, a relationship, and a path into a scene. It can be a person, belief, place, possession, or trait, but not an abstract optimization like "my money."

Do not pick something you do not care about to keep it safe from horror. That defeats the point; the game is stronger when the character must decide whether to risk it. And do not ask the Keeper to avoid it. Tell the Keeper what kind of involvement you welcome: letters, requests for help, professional introductions, tense reunions, or a chance to defend the belief in a crisis.

### Let Skills And Occupation Suggest History

Your occupation, skill choices, [Credit Rating](/articles/coc-7e/character-creation/credit-rating), and characteristics already imply a past. Use them as prompts instead of inventing a separate character who happens to have the numbers on the sheet.

For every unusually high skill, ask how the investigator learned it. A high Firearms skill might come from rural hunting, military service, a security job, or anxious self-protection after an attack. A strong Library Use score might come from formal study, years in a records office, or an obsessive private project.

| Sheet choice                 | Backstory question                           | Playable result                                                   |
| ---------------------------- | -------------------------------------------- | ----------------------------------------------------------------- |
| Occupation                   | Why this work, and why now?                  | A colleague, workplace, professional obligation, or former client |
| High personal-interest skill | Who or what taught it?                       | A hobby group, mentor, old incident, or recurring location        |
| Low Luck                     | What repeatedly goes wrong in ordinary life? | A recognizable habit of caution, debt, delay, or strained trust   |
| High Credit Rating           | What holds that standing together?           | Family expectations, a firm, reputation, property, or patronage   |
| Low Credit Rating            | What is the current pressure?                | A job change, obligation, community tie, or precarious routine    |

Do not explain every point. One strong reason beats a fake history for every skill.

### Make Each Hook Specific And Emotional

Aim for entries that are specific, emotional, and emphatic, meaning each one holds enough feeling to guide a decision without tipping into melodrama. Revise in three passes:

1. Name the subject: "my sister."
2. Add the relationship: "my sister Ada, who raised me."
3. Add the pressure: "my sister Ada, who raised me, and whom I will not disappoint again."

The final version tells you why a telegram from Ada matters, and it tells the Keeper how to make a situation personal without inventing details on the spot.

| Weak note            | Playable revision                                                            |
| -------------------- | ---------------------------------------------------------------------------- |
| "Has a friend"       | "Tommy Rusk owes me his life, though he still blames me for the fire."       |
| "Believes in ghosts" | "My grandmother spoke to the dead, and I will prove she was not mad."        |
| "Owns a gun"         | "I keep my brother's service revolver cleaned, unloaded, and close at hand." |
| "Ambitious"          | "I will be invited into the society that laughed at my mother."              |

Specificity creates choices. Emotion creates stakes. Strong wording gives you something to play when the investigator is tired, frightened, or tempted to walk away.

### Leave Space For The Campaign

Do not write the whole campaign before the Keeper starts it. Leave two kinds of space:

- **Unanswered history:** a missing year, estranged relative, former job, or unresolved rumor that can matter later.
- **Emotional flexibility:** a belief or relationship with room to change when the investigator learns something terrible.

One mystery about the past is useful. Six compete with the actual scenario.

A player may add or alter background entries whenever they like, with limits. Entries under Injuries and Scars, Phobias and Manias, and Encounters with Strange Entities, and anything the Keeper added, cannot be changed without the Keeper's permission, and phobias and manias only go away through treatment. Discuss big changes at the table, so the backstory stays shared fiction instead of a way to grant a perfect contact or alibi whenever an obstacle appears.

Historical context can root an investigator in the setting. Pick one event (a war, strike, migration, epidemic, failed expedition, or local political fight) and ask what the investigator witnessed, lost, gained, or refused; which current belief or habit came from it; and who remembers it differently. In a 1920s game, a veteran's old unit or a family hit by the influenza pandemic gives instant texture. Research enough to avoid anachronism and stereotypes, and do not claim an experience you cannot portray respectfully.

### How Backstory Changes In Play

Investigators are supposed to change. A serious wound leaves a scar. Each time an investigator suffers a bout of madness, the Keeper may amend an existing entry or add a new one, and an encounter with an entity or a forbidden tome goes on the sheet for good.

Treat those changes as collaboration. The Keeper should tie a new phobia, mania, scar, or altered belief to what happened, and the player should help find a version that is uncomfortable and meaningful without turning the character into a joke. "Avoids tunnels after the flooded cellar" gives future scenes texture. A random fear with no link to events usually does not.

Backstory is also how investigators heal. In the development phase, self-help recovery asks the player to describe a fitting act tied to an entry, such as a religious retreat, a holiday with a loved one, or restoring a workshop. On a successful Sanity roll the investigator regains 1D6 Sanity. On a failure they lose 1 Sanity and the Keeper and player revise that entry to reflect it. That is why early entries need warmth as well as plot hooks: a backstory of only enemies and secrets offers nothing when the investigator needs a reason to come back from the edge.

### Three Sample Backstories

**The journalist who hates silence.** Description: always carries a notebook; talks when nervous. Belief: "Nothing survives daylight and a printed page." Significant person: editor Mara Bell, who gave the investigator a first chance and expects results. Location: the newspaper morgue, where old clippings make sense of the city. Possession: a fountain pen from a late mentor's desk. Trait: cannot leave a witness unheard. Mara can supply a lead, apply pressure, or become someone to protect.

**The doctor with a closed door.** Description: immaculate cuffs and exhausted eyes. Belief: "A life is worth the cost, even when the patient hates me for it." Significant person: younger cousin Elsie, whose recovery convinced the doctor to keep practicing. Location: the clinic's locked records room. Possession: a damaged medical bag inherited from a parent. Trait: refuses to abandon the sick. Elsie is a strong key connection because the player has a clear reason to seek her out during recovery and to risk something for her.

**The mechanic who cannot go home.** Description: oil under the nails despite constant scrubbing. Belief: "Every machine tells the truth eventually." Significant person: former foreman Caleb Pike, who knows why the investigator left town. Location: a riverside repair yard that still feels like home. Possession: a brass wrench with a family name filed off. Trait: takes apart anything that does not make sense. The unexplained departure is deliberate space, not a demand that Caleb become a villain.

## Age, Luck, And Equipment

Age is a real choice, not a number next to the portrait. Pick any age from 15 to 90 and apply only that band's modifiers; they are not cumulative. Teenagers lose points from STR, SIZ, and EDU but roll Luck twice and keep the higher result. Every band from 20 up makes EDU improvement checks, and from 40 on the investigator also loses physical points, APP, and movement. The [Age Rules Guide](/articles/coc-7e/character-creation/age-rules) has the full table.

Luck is separate from POW. It is rolled as 3D6 x 5 and represents fortune when circumstances are beyond the investigator's direct control. Treat it as a value worth understanding, not a substitute for planning. A good plan can still meet bad luck; a poor plan does not become sound because the dice cooperate once.

Finances come from Credit Rating. Look it up on the rulebook's cash and assets table to get spending level, cash, and assets; the sample 1920s journalist with Credit Rating 41 has an Average living standard and a $10 daily spending level with no bookkeeping. Equipment should follow the era, occupation, finances, premise, and the Keeper's assumptions. Start with what an ordinary person in that role owns or can arrange. A camera, medical bag, legal folder, toolkit, or field notebook often contributes more to a first investigation than trying to carry an answer to every threat.

## Use Pre-generated Investigators Well

A pre-generated investigator is a character whose mechanical work is already done so the group can spend its first session investigating. The Investigator Handbook includes sample investigators meant as inspiration or as ready-to-play characters, published scenarios often supply their own, and the Keeper Rulebook recommends pregens for games with a fixed time slot, such as conventions. A finished sheet is an invitation to play, not a limit on ownership.

### What Stays Fixed And What You Own

The worry is fair: someone else chose the occupation, skills, and history, so how does the investigator become yours? Separate the parts that need to stay stable from the parts that create voice.

| Usually stable                          | Usually open to the player                                |
| --------------------------------------- | --------------------------------------------------------- |
| Characteristics and derived values      | Name, pronouns, voice, and presentation                   |
| Core skill values                       | How skills were learned and what they look like in action |
| Occupation and broad financial position | Current job details, relationships, and daily routine     |
| Essential scenario tie                  | The investigator's reason for accepting the call          |
| Any established campaign history        | The personal meaning of a belief, place, or possession    |

You do not need to rewrite every line; heavy rewriting defeats the point of a pregen. Answer a few questions that matter under pressure instead. Why do they keep doing this work? Whom do they think of before taking a risk? What do they fall back on when frightened? Once play starts, the pregen gains skills, loses Sanity, picks up scars, and revises its backstory like any other investigator.

### When To Use A Pregen

Pregens are not only for beginners. Use them when:

- You are running a one-shot, convention game, or short introductory scenario.
- The table wants to start the mystery in the first session.
- A new player would rather learn the rules from a completed sheet.
- The scenario assumes a shared organization, expedition, institution, or social circle.
- A player needs a replacement investigator mid-campaign.
- The group enjoys character play but not allocating skill points.

Build from scratch when the campaign is long, players care about designing concepts, or the premise has no shared starting organization. Mixed tables work too, as long as the Keeper checks that custom and prepared investigators start on comparable assumptions.

Pregens save setup time. They do not fix an unclear tone, unwanted themes, or a player stuck with a role they dislike. Explain the premise before anyone chooses, and offer roles rather than assigning them. "You are the doctor" is weaker than "This investigator is a doctor whose professional ethics keep pulling them into this case. Does that interest you?"

### Choose A Role, Not The Biggest Numbers

Do not pick a pregen by scanning for the highest percentage. Start with the role you want at the table:

| Role you want to play  | Look for                                                          | What it contributes                                        |
| ---------------------- | ----------------------------------------------------------------- | ---------------------------------------------------------- |
| The researcher         | Academic knowledge, records access, languages, Library Use        | Context, interpretation, and documentary leads             |
| The interviewer        | Interpersonal skills, social confidence, professional credibility | Witnesses, introductions, and difficult conversations      |
| The observer           | Spot Hidden, Listen, Psychology, practical caution                | Details others miss and suspicion of the wrong explanation |
| The field investigator | Mobility, survival skills, mechanical competence, steadiness      | Travel, dangerous locations, and tangible obstacles        |
| The protector          | First Aid, physical capability, courage under pressure            | Keeping the group moving when events turn violent          |
| The insider            | A role tied to the scenario's place or institution                | Plausible access and local knowledge                       |

These are lenses, not classes. A journalist can be observer and interviewer at once. Choose the sheet whose decisions you want to narrate.

Every pregen also needs a reason to investigate stronger than "the group told me to come." If the sheet lacks one, add a sentence before play: "The missing clerk once covered for me when I needed it most," or "My old mentor sent a letter that does not sound like them." Point the hook at the scenario without revealing the solution, and avoid a private secret that makes the character responsible for everything supernatural in the campaign.

### Read The Sheet In The Right Order

New players often start with the skill list and stop there. Read in this order instead:

1. **Name, occupation, and situation:** who is this person on an ordinary day?
2. **Backstory entries:** which people, places, beliefs, possessions, and traits can shape a decision?
3. **Key connection:** what gives this life particular meaning?
4. **Best skills:** what can they credibly attempt?
5. **Weaknesses:** what do they avoid, lack, or need from the group?
6. **Resources:** what do occupation and Credit Rating imply about access and spending?
7. **The scenario hook:** why leave the safe routine today?

Mark three skills you expect to use and learn the rest as situations arise. A high value gives a strong chance when the skill applies, not unlimited authority. A detective does not command every police officer, and a scholar does not know every forbidden fact. The Keeper decides whether a roll fits and what success accomplishes, so ask questions and describe sensible actions instead of hunting for the one button labeled "solve mystery."

### Claim Three Details Before Play

Give every player five minutes to claim three details:

1. **One relationship:** a person the investigator cares about, relies on, or cannot stand.
2. **One habit or visible detail:** how they enter a room, dress for work, handle stress, or speak to authority.
3. **One personal stake:** why this case matters now.

These should not change skill values or break the scenario tie. They tell the player how to portray the prepared numbers. A pregen doctor could be calm, impatient, devout, skeptical, or privately exhausted, and the sheet does not need to decide which. Use the backstory advice above to sharpen them: "my brother" is a seed, but "my brother Arthur, who kept writing after the war when I could not" is a relationship you can play.

### Adapt A Pregen Safely

Change only what improves ownership or fits the agreed setting.

| Change                                                  | Usually safe before play | Discuss with the Keeper                                  |
| ------------------------------------------------------- | ------------------------ | -------------------------------------------------------- |
| Name, pronouns, appearance, voice                       | Yes                      | Only if the scenario relies on a specific identity       |
| Personal details and minor relationships                | Yes                      | If they replace an essential scenario connection         |
| Occupation title or workplace flavor                    | Often                    | If it changes skill assumptions or access                |
| Key connection                                          | Often                    | If the pregen has an established campaign key connection |
| Skill values and characteristics                        | No                       | Yes, especially in a shared one-shot                     |
| Equipment, cash, or major assets                        | No                       | Yes                                                      |
| Mythos knowledge, spells, or prior supernatural history | No                       | Yes                                                      |

Preserve the scenario role and the table's fairness. A player can rename a professor and change their style of scholarship, but should not turn them into a trained criminal because that sounds more useful. For a replacement investigator in a running campaign, the Keeper decides how much experience, equipment, and knowledge fits, so the newcomer is viable without arriving with the answer to the current problem.

Keep at least one bit of friction, too: an awkward trait, an inconvenient relationship, modest resources, or a weak skill. It creates decisions and stops every pregen becoming the same flawless detective in different clothes.

### Connect The Group To The Scenario

Pregens work best with a believable reason to cooperate. Pick one group frame before play:

| Group frame           | Why it works                                        | First-scene prompt                            |
| --------------------- | --------------------------------------------------- | --------------------------------------------- |
| Professional network  | Members can credibly call on one another            | A colleague asks for discreet help            |
| Investigation society | The group already studies odd events                | A trusted contact brings an unusual case      |
| Friends and family    | The relationships create immediate stakes           | Someone close to the group is in trouble      |
| Shared prior event    | The characters share a bond and unfinished business | A familiar detail from the past appears again |
| Local community       | Everyone knows the setting's ordinary rhythms       | A disruption threatens a place they know      |

The Investigator Handbook's own samples come grouped this way, including members of a society that explores the unexplained. Then give each investigator one sentence about another: trust, rivalry, obligation, shared work, old affection, or mild suspicion. Two or three clear lines keep the opening from becoming a room of strangers waiting for a plot coupon.

### Common Pregen Mistakes

- **Choosing only for combat:** violence is dangerous in this game and often makes things worse. Pick someone who can investigate, talk, or get around as well as survive a bad turn.
- **Treating the backstory as fixed lore, or ignoring it:** change a name or clarify a motive within the scenario's limits, but use the personal notes; they are how a prepared investigator becomes vulnerable to the story.
- **Giving the most complex sheet to the newest player:** new players need a clear role, a few obvious strengths, and a direct hook. Complexity belongs with the player who wants it.
- **Making one pregen the protagonist:** spread information and emotional stakes so nobody plays a cameo.
- **Rewriting until it is a new character:** if a player wants a new occupation, skills, resources, and hook, build a custom investigator with the [Character Sheet Guide](/articles/coc-7e/character-creation/character-sheet-guide) instead.

### A First-Session Procedure

1. Explain the era, location, tone, and starting premise.
2. Lay out the pregens with a two-line role summary, not only their statistics.
3. Let each player choose the role they want.
4. Give players time to read the sheet in the order above.
5. Have each player claim a relationship, a habit, and a personal stake.
6. Set the group frame and one connection between investigators.
7. Confirm any mechanical changes with the Keeper.
8. Open on an event that demands a decision, not a lecture about the setting.

A telephone call, missing person, damaged artifact, or plea for help gets characters moving. For a fast start, pair this with the [Quick Start guide](/articles/coc-7e/getting-started#quick-start-guide-for-your-first-session).

## A Party Check Before Play

Take five minutes once everyone has a draft, whether custom or pregen. Each player answers aloud:

1. What first drew your investigator toward the premise?
2. What kind of lead can they pursue especially well?
3. What is one thing they will need help with?
4. Which other investigator do they know, trust, owe, or recognize?
5. What would make them continue after the first frightening discovery?

A healthy group usually has someone comfortable with strangers, someone who can notice or interpret evidence, someone who can handle practical danger or travel, and a credible reason for everyone to be there. Do not force every category. Two researchers can carry an academic horror story, and a group of reporters can chase a single story.

This is where duplicate concepts become useful. Two academics might know each other from a professional dispute; two social investigators can approach the same witness differently. Resolve overlap only when it makes someone else's role disappear.

Watch for the lone specialist trap. If only one investigator has a key skill, that player is not the group's button-pusher; others can help through contacts, tools, questions, and alternate plans. And a character who can fight is valuable, but not a substitute for investigation, caution, or a reason to care.

## Advice For Keepers

State the campaign assumptions before the group builds characters: era, starting location, premise, tone, how the investigators relate, and any limits on occupations or resources. You do not need to reveal the conspiracy to say the first scenario concerns a university expedition, a local murder, or a family estate. Encourage varied investigative routes and make sure the opening offers more than one way to learn essential information, so gaps create choices instead of locked doors.

### Using Player Backstories

Read each investigator's entries before the first scenario and note one invitation (a contact, place, or obligation that can deliver information), one pressure point (a belief, responsibility, or trait that makes a decision personal), and one recovery scene (a connection that can support them between cases). The rulebook also suggests weaving backstories into the scenario itself: rename a town or turn an existing NPC into someone a player already mentioned.

Use these elements with consent and proportion. A significant person does not need to be kidnapped to matter; a letter, a worried question, or a chance to disappoint someone is often enough. When you threaten a key connection, give the promised roll instead of declaring the loss off-screen. When madness or injury calls for a new or changed entry, work with the player so the result reflects what happened and creates future roleplay.

### Preparing Pregens For Other Players

The Keeper Rulebook's advice for writing investigators for other people is practical:

- **Use quick archetypes** such as the grizzled ex-cop or the curious reporter.
- **Balance the spotlight.** Every investigator needs strengths that will come into play; that does not mean equal skills. Do not center the scenario on one character.
- **Keep backstories short.** If the scenario depends on an investigator knowing something, make it obvious, and give players time to read at the start. Bullet points help.
- **Consider leaving some skill points unallocated** so each player can customize.
- **Tell each investigator what they know about the others**, from their own partial and possibly mistaken point of view.
- **State facts, not feelings.** Tell the player what their investigator perceives and let them decide how they feel.

Put the role, strengths, key connection, and hook where a player can find them quickly, and state the group frame. Offer choice before assignment: a scenario may need someone tied to a particular institution, but you do not need to decide which player plays them. Approve small cosmetic changes unless they damage the premise, and decide mechanical rewrites openly for the whole group.

## Player Checklist

- Know the era, premise, and how your investigator knows the others.
- Write a one-sentence premise tie before spending points.
- Record full, half, and fifth values after both skill pools are spent.
- Build one professional strength, one information route, and one deliberate gap.
- Write three to six short backstory entries and star a key connection you care about.
- Leave room for injuries, fears, strange encounters, and changed beliefs.
- With a pregen, choose the role you want, read the sheet in order, claim three details, and keep the scenario hook intact unless the Keeper agrees.
