Call of Cthulhu 7e Skill Points Guide

Introduction

Every Call of Cthulhu 7e investigator spends two pools of skill points at creation: occupation points and personal interest points. The math is short, but the two pools have different sources and different limits. This guide covers both, with worked examples and a checklist for the finished sheet.

Hot Take

Skill points should make an investigator recognizable before they make the investigator efficient. A sheet with high numbers in the usual suspects may survive its first scene, but it rarely gives the player a compelling way to enter the second or third one. Spend points to establish a working life, a private life, and a few credible ways to get into trouble.

The mechanics are simple. The judgment is not.

The Two Skill Point Pools

Call of Cthulhu 7e uses two pools during standard character creation. Keep them separate while allocating them. They have different sources and different permissions.

The occupation formula varies. Many scholarly professions use EDU x 4; other occupations combine EDU x 2 with another characteristic multiplied by two. Use the exact formula printed with the occupation rather than assuming every character receives the same total.

Points are percentage points added to the printed base value of a skill. They are not the skill's final total. A 25-point investment in a skill with a 20% base becomes 45%, not 25%.

A Pool Is Not a Wishlist

Occupation points cannot be spent on a convenient non-occupation skill just because the group lacks it. Personal-interest points are the flexible pool for that. Conversely, do not treat personal-interest points as a dumping ground for unrelated high values. Every large investment should have a sentence of history behind it.

Points you do not allocate are lost, so complete the allocation. Do not calculate half and fifth values until both pools have been spent; personal-interest points may raise occupation skills further.

Calculate Your Pools

Use this sequence before choosing individual skills:

1. Choose the occupation and copy its point formula, listed skills, and Credit Rating range.
2. Apply the formula using the investigator's final characteristics after age adjustments or any Keeper-approved creation option.
3. Calculate personal-interest points as INT x 2.
4. Write the two totals in separate temporary boxes.
5. Check the occupation's Credit Rating range before spending the first occupation point.

Example Calculations

The example formulas illustrate the pattern, not a replacement for the occupation entry. A concept can use a different formula and still make complete sense. The formula is a mechanical signal about the kind of preparation that occupation rewards; it is not a verdict on whether the character is intelligent, interesting, or competent.

Spend Occupation Points First

The Occupations Guide covers the roleplaying value of a job. Here, focus on the accounting: occupation points go among the listed occupation skills. Credit Rating is part of that allocation and must land inside the occupation's recommended range unless the Keeper approves a different story.

Use this order:

1. Set Credit Rating. Pick a value within the range that reflects rank, income, family circumstances, or professional success.
2. Choose two professional anchors. These are the skills the investigator can rely on when performing their actual job.
3. Choose one access skill. It may be social, research-based, technical, or practical, but it should explain how the job reaches a case.
4. Support the rest of the profession. Give the remaining listed skills enough attention that the job feels real without trying to maximize everything.
5. Spend every remaining point. Recheck the pool total before moving to personal interests.

The occupation pool has rules of its own that the sequence above takes for granted. Credit Rating starts at zero and has to be bought inside the occupation's recommended range. A listed broad category such as Art/Craft, Fighting, Firearms, Science, Pilot, Survival, or Language (Other) has to be bought as a named specialty: points buy Science (Chemistry), never generic Science. Points cannot leak onto skills the occupation does not list.

The Occupation Skill Points Guide owns all of that in full, including custom occupations and what to do when a pool will not balance, and the Complete Skills List shows where specialties overlap.

Use Personal Interests to Make a Person

Personal-interest points equal INT x 2. They can be placed in any skill and may strengthen occupation skills. They cannot normally be spent on Cthulhu Mythos. That restriction is intentional: Mythos knowledge is usually acquired during play and carries a cost the player should not treat as a standard character-build option.

Use this pool to answer questions the occupation cannot:

Personal interests can reinforce a professional anchor. That is often better than spreading every point across unrelated skills. A reporter with strong Persuade and Psychology may have learned both on the job and during years of volunteer work. What matters is that the final value reflects a believable life.

Add Points to Base Values

Every skill starts with a base chance on the investigator sheet. Add allocated points to that base, then record the resulting full skill value. A few examples:

The final value is what you use for rolls. After both pools are allocated, write its half and fifth values on the character sheet. The resulting thresholds are used for Hard and Extreme difficulty, so do not calculate them from only the points you added.

Own Language Is Different

Own Language normally begins at the investigator's EDU value, rather than a small printed base. It may be raised further during character creation if the concept supports it. Do not mistake it for Language (Other), which is a named specialty with its own base chance and investment.

A Complete Allocation Example

Mara is an archive researcher whose EDU x 4 occupation formula produces 280 occupation points. Her INT is 65, so she has 130 personal-interest points. Her profession lists research, academic, social, and Credit Rating options.

First, Mara chooses Credit Rating 30 inside the occupation's range. That costs 30 occupation points, leaving 250. She wants to be an excellent archival researcher, so she invests 55 into Library Use and 45 into History. She invests 35 into Persuade because her work requires access to restricted collections, 30 into Psychology to read reluctant donors, and distributes the remaining 85 among the other listed professional skills that show how she actually does her job.

Then Mara uses personal-interest points to build her private life. She invests in Occult because she has spent years collecting local folklore, Drive Auto because she travels to rural archives, First Aid because she volunteered during the war, and a modest Fighting specialty because a Keeper-approved backstory supports it. She uses the remainder to strengthen Library Use instead of buying a string of 10% curiosities.

The result is not "the perfect researcher." It is an investigator who can find a lead, persuade a gatekeeper, understand why a document matters, travel to a remote site, and remain present when the case becomes dangerous. Just as important, every investment gives Mara a scene the player can describe.

Build for the Whole Investigation

Prioritize capability by role, not by a universal ranking. A useful group generally has multiple ways to do each of these things:

Do not force a party spreadsheet. Overlap is healthy, and a group can solve the same problem through different methods. The useful conversation is not "Who is the party face?" It is "How can each investigator make progress when their preferred route is blocked?"

High Values Need a Job

A high value is an invitation for the Keeper to give the investigator a chance to shine, not a guarantee that every obstacle disappears. Put your largest investments in skills the player wants to describe repeatedly. A 70% skill should reflect deep practice, responsibility, or fixation. A collection of medium values can represent a versatile amateur. Both are valid; choose deliberately.

Common Allocation Mistakes

Forgetting the Base Value

Writing only the points spent produces a skill that is too low and makes later recalculation confusing. Always record base plus points as the final value.

Spending Occupation Points Everywhere

Occupation points only buy the listed professional skills and Credit Rating. Keep that pool separate. A desired non-occupation skill belongs in personal interests unless the Keeper changes the occupation or approves a custom one.

Ignoring Credit Rating

Credit Rating is part of the job's point budget and establishes a concrete starting social position. Leaving it at zero by accident creates an investigator whose sheet contradicts their concept.

Buying Cthulhu Mythos at Creation

Personal-interest points do not normally buy Cthulhu Mythos. The Keeper may make a specific exception, but that should be a campaign decision with story and Sanity implications, not a casual optimization choice.

Calculating Half and Fifth Too Early

Personal-interest points can add to occupation skills. Finish both pools first, then calculate all final thresholds once.

Letting the Sheet Replace the Backstory

Every major skill should answer a simple question: where did this investigator learn it? The Backstory Guide gives those answers consequences, relationships, and usable hooks.

Final Sheet Audit

Before the first session, verify:

1. The occupation point formula uses the final relevant characteristics.
2. Every occupation point is assigned only to a listed occupation skill or Credit Rating.
3. Credit Rating is inside the recommended range or has Keeper approval.
4. Personal-interest points equal INT x 2 and do not buy Cthulhu Mythos without approval.
5. Each specialty has a precise name.
6. Every full skill value includes its base chance.
7. Half and fifth values were calculated after both pools were spent.
8. Every highest-value skill has a clear place in the investigator's life.
9. The investigator has more than one way to contribute when a lead, person, or location refuses the easy approach.

Skill-point allocation is complete when the numbers are correct and the investigator already feels capable of making a bad decision for a good reason.
