Introduction
Dark Archive is Pathfinder 2e's occult investigation book: psychic pressure, cursed evidence, impossible doubles, monster folklore, hidden societies, deviant powers, dream logic, bargains, and the sort of clues that make players ask whether touching the object was a good idea.
The book adds two major classes, a rare heritage, a pile of paranormal archetypes, occult spells and rituals, cryptid tools, secret society and cult material, deviant abilities, mindscapes, psychic duels, and eight casefile-style adventures. For Remaster play, treat it as a valid expansion source with updated terminology, normal rarity/access rules, and stronger session-zero handling than a basic player option book.

What Dark Archive Adds
| Area | What it adds | Site home |
|---|---|---|
| Classes | Psychic and Thaumaturge | Classes |
| Class feats | Psychic and Thaumaturge feat lines, plus build-defining class choices | Psychic feats, Thaumaturge feats |
| Heritage | Reflection, a rare versatile heritage about doubles, echoes, and created identities | Heritage guide |
| Archetypes | Psychic, Thaumaturge, Alter Ego, Chronoskimmer, Curse Maelstrom, Living Vessel, Mind Smith, Pactbinder, Psychic Duelist, Sleepwalker, and Time Mage | Dark Archive archetypes |
| Rules | Deviant abilities, mindscapes, psychic duels, and paranormal rule frameworks | Rules |

| Magic | Psychic-flavored occult spells, deviant spells, temporal magic, cult rituals, and mindscape rituals | Spell guides |
| Gear | Cryptid gear, secret society gear, cursed items, and strange investigation tools | Equipment |
Hot take: Dark Archive is not strongest as a player options buffet. It is strongest when the GM lets the unknown push back.
Who Should Use Dark Archive
| Table type | Recommendation | Why |
|---|---|---|
| Occult investigation campaign | Strong add | Psychic clues, Thaumaturge lore, secret societies, cults, mindscapes, and cryptids all get regular table time |
| Monster-of-the-week campaign | Strong add | Thaumaturge, cryptids, rumors, creature traits, and research make each threat feel distinct |
| Political intrigue campaign | Good add | Alter Ego, Pactbinder, secret societies, cult influence, and hidden identities fit naturally |
| Dungeon crawl campaign | Selective add | Psychic and Thaumaturge work, but the GM should add haunts, cursed objects, evidence, and research scenes |
| Straight tactical arena | Mixed | The classes still function, but Reflection, mindscapes, cults, pacts, and casefile tools lose much of their oxygen |
| New PF2e table | Use carefully | The classes are more complex than the easiest starter classes, and rare options need extra agreement |
If your table enjoys asking "what is this thing?" before asking "how hard do I hit it?", Dark Archive earns its shelf space.
Adoption Models
You do not need the entire book active at once.
| Adoption model | What you allow | Best for |
|---|---|---|
| Classes only | Psychic and Thaumaturge with normal feat support | Campaigns that want new player builds without rewriting the campaign tone |
| Occult character package | Classes, Reflection, Dark Archive archetypes, occult spells, and strange gear with GM approval | Parties that want paranormal PCs and investigation hooks |
| GM weirdness package | Cryptids, mindscapes, deviant abilities, secret societies, cults, and casefile pacing | GMs who want the world to feel stranger without giving every PC new subsystems |
| Full Dark Archive campaign | Everything above, with mysteries, factions, rare access, recurring occult threats, and casefile-style arcs | Campaigns about the unknown as the central premise |
Hot take: the safest on-ramp is Psychic plus Thaumaturge plus one weird GM-facing tool. If you add Reflection, deviant abilities, mindscapes, pacts, cryptids, and secret societies all at once, the campaign can become a bulletin board with tentacles.

Player Options Review
Psychic
Psychic is an occult caster whose identity is built around psi cantrips, amps, focus points, conscious mind, subconscious mind, and the timing window of Unleash Psyche. It is not just "Wizard, but spooky." It has fewer traditional spell slots than full slot-heavy casters, so its repeatable cantrip and focus economy matters a lot.
Best fits:
| Player goal | Why Psychic fits |
|---|---|
| Repeatable magical offense | Psi cantrips and amps make cantrip turns matter more than they do for many casters |
| Occult investigation | Occult spellcasting, mental effects, and perception of strange phenomena fit the book's mysteries |
| Tactical burst windows | Unleash Psyche rewards choosing the right moment instead of spending every resource immediately |
| Character-driven magic | Subconscious mind and conscious mind make the source of power part of play |
Use Psychic with psychic spells, occult spells, cantrips, focus spells, Occultism, and combat spells.
Hot take: Psychic is a focus economy class wearing a spellcaster coat. If you ignore amp timing and Unleash Psyche, you are leaving the best part of the class in the evidence locker.
Thaumaturge
Thaumaturge is a Charisma-based martial occultist who turns folklore, trinkets, implements, and monster knowledge into combat pressure. Its core fantasy is not "I know the monster's stat block." It is "I know the rumor, the weakness, the old superstition, and the right object to make that matter."
Best fits:
| Player goal | Why Thaumaturge fits |
|---|---|
| Monster hunting | Esoteric Lore and implement play make creature traits and weaknesses feel central |
| One-handed martial play | Implements and esoterica often ask for careful hand management |
| Strange utility | Scrolls, talismans, implements, and occult tools give the class a broad kit |
| Charisma investigator | The class can be socially active without becoming a full face caster |
Use Thaumaturge with Thaumaturge feats, creature traits, monster stat blocks, Recall Knowledge skills, talismans and consumables, worn and invested items, and runes.
Hot take: Thaumaturge makes knowledge feel like damage without reducing it to trivia night. That is the trick. The monster should still surprise you.
Reflection
Reflection is a rare versatile heritage for characters who are doubles, echoes, replicas, or uncanny copies. It is one of the most campaign-sensitive options in Dark Archive because it changes identity, social risk, and backstory visibility.
Best fits:
| Character premise | Why Reflection fits |
|---|---|
| Clone or duplicate | The heritage supports "who is the original?" tension |
| Escaped experiment | Pairs naturally with secret societies, deviant powers, and occult laboratories |
| False identity campaign | Works with Alter Ego, Deception, infiltration, and political play |
| Paranormal mystery | The character can be evidence, victim, suspect, and investigator at the same time |
Use Reflection with heritages, versatile heritages, Deception, Society, and session zero.
Hot take: Reflection is not a cosmetic ancestry tag. If nobody at the table cares who made you or who you resemble, the option loses half its reason to exist.
Dark Archive Archetypes
The Dark Archive archetypes guide covers the book's paranormal side doors. Psychic and Thaumaturge archetypes are the easiest broad recommendations. Mind Smith, Chronoskimmer, and Time Mage are strong when the build can use them regularly. Alter Ego, Living Vessel, Pactbinder, Curse Maelstrom, Sleepwalker, and Psychic Duelist need a campaign that rewards their story hooks.
Quick read:
| Archetype lane | Best when |
|---|---|
| Psychic archetype | A character wants occult cantrip identity, amp support, and mental-stat utility |
| Thaumaturge archetype | A Charisma martial wants implement flavor, esoterica, and monster-hunter texture |
| Mind Smith | A martial wants a signature psychic weapon as the build's centerpiece |
| Chronoskimmer | Initiative, time tricks, and action timing matter often |
| Time Mage | A spellcaster wants temporal focus and spell texture |
| Alter Ego | Disguise, infiltration, false identity, and social deception are regular scenes |
| Living Vessel | The table wants possession, body horror, bargain pressure, and rare access |
| Pactbinder | Deals, obligations, outsiders, entities, and social consequences matter |
| Curse Maelstrom | The campaign uses curses often enough for curse pressure to become a feature |
| Sleepwalker | Dreams, mindscapes, and occult sleep logic are recurring campaign tools |
| Psychic Duelist | Psychic duels or mental-realm conflict happen enough to justify specialization |
Hot take: Dark Archive archetypes are often powerful in the right campaign and theatrical dead weight in the wrong one. That is not a flaw; it is the book telling you to talk to your GM.
GM Options Review
Cryptids
Cryptids are not just monsters with a blurry photo. Dark Archive frames them around witness reports, signs, secrecy, abnormal behavior, and creature adjustments that make a familiar threat feel wrong.
Good cryptid play asks:
| Question | Why it matters |
|---|---|
| What did witnesses see? | Rumors give players something to investigate before initiative |
| What evidence is reliable? | Tracks, wounds, symbols, missing memories, and false sightings create choices |
| What does the creature want? | Behavior matters more than surprise weirdness |
| What makes it different from the normal creature? | Adjustments should change tactics, not just add a hat |
| What happens if the PCs expose it? | A cryptid story should affect public fear, faction action, or local belief |
Use cryptids with creature traits, encounter use, custom monsters, hazards, and Occultism.
Secret Societies And Cults
Secret societies and cults give Dark Archive campaigns social structure. They turn the occult from "one strange basement" into networks of patrons, cells, rivals, membership benefits, forbidden doctrines, rituals, gear, services, and consequences.
Use them when the campaign needs:
| Need | Dark Archive tool |
|---|---|
| Recurring antagonists | Cells, cult leaders, agents, and hidden patrons |
| Player temptation | Membership services, pacts, forbidden knowledge, and access |
| Social pressure | Reputation, suspicion, blackmail, favors, and public consequences |
| Research structure | Clues that point to doctrine, symbols, history, and rival theories |
| Adventure continuity | The next case is connected to the last one without needing a single mastermind behind everything |
Use social encounters, subsystems, skill DCs, Diplomacy, Deception, Religion, and Society.
Hot take: secret societies are best when they offer something useful. A hidden group that only exists to be evil is less interesting than one that can help the PCs at a cost.
Deviant Abilities
Deviant abilities are rare supernatural powers with backlash, quirks, awakenings, and story weight. They are not normal feats and should not be handed out like party favors.
Best uses:
| Use | Why it works |
|---|---|
| Shared paranormal event | Every PC gets comparable spotlight and consequences |
| One-character mystery | A PC's power becomes a campaign hook, not a free upgrade |
| Villain mirror | Enemies show what the same power source costs |
| Occult experiment | The party escaped or survived something that left marks |
| Cosmic exposure | An entity, artifact, or impossible location changed the characters |
Use session zero, variant rules, conditions, and treasure by level to keep the power budget and spotlight sane.
Hot take: the drawback is part of the point. If the player wants the ability but not the backlash, give them a normal feat instead.
Mindscapes
Mindscapes are mental realms where memory, emotion, self-image, belief, and thought can become terrain. They are one of the best tools in Dark Archive because they make psychic and occult stories playable at the table.
Good mindscape scenes define:
| Element | Table question |
|---|---|
| Entry | Dream, spell, ritual, artifact, trap, possession, or psychic event? |
| Reality rules | What changes about distance, time, memory, death, healing, or movement? |
| Stakes | What happens if the party wins, fails, wakes up, or gets trapped? |
| Opposition | Creature, thoughtform, memory, hazard, emotion, or the mindscape itself? |
| Exit | Victory, discovery, negotiation, ritual completion, or self-knowledge? |
Use hazards, subsystems, Occultism, Religion, Society, and psychic spells.
Hot take: a mindscape is not good because it is weird. It is good when the weirdness changes decisions.
Magic And Gear
Dark Archive adds magic and gear that support occult investigation more than routine dungeon math.
| Option type | Best use | Related guide |
|---|---|---|
| Psychic spells | Cantrip pressure, mental effects, force, movement, defense, and occult utility | Psychic spells |
| Occult spells | Emotion, thought, shadow, spirit, fear, illusion, and strange utility | Occult spells |
| Deviant spells | Paranormal power tied to deviant themes and GM permission | Deviant abilities |
| Mindscape rituals | Long-form psychic and dream-facing scenes | Rituals, mindscapes |
| Cult rituals | Campaign-facing occult pressure, doctrine, and dangerous group magic | Secret societies and cults |
| Cryptid gear | Evidence, tracking, investigation, and monster-hunting prep | Adventuring gear and tools |
| Cursed items | Story complications, bargains, consequences, and dangerous treasure | Magic items by level |
For normal PF2e support, still use staves and wands, consumables, worn and invested items, and treasure by level. Occult style does not replace item math. The cursed mirror can be narratively fascinating and still fail to cover your missing armor rune.
How It Fits With The Core Books
Dark Archive works best when it sits on top of the Remaster core instead of floating off into unruled weirdness.
| Source | What it contributes to Dark Archive play |
|---|---|
| Player Core | Actions, checks, conditions, spell traditions, skill actions, exploration mode, rituals, equipment basics, and character rules Psychic and Thaumaturge still use |
| Player Core 2 | Comparison points for complex classes: Investigator, Oracle, Alchemist, Monk, and Swashbuckler |
| GM Core | Rarity, access, DCs, research, social encounters, hazards, treasure pacing, subsystems, rewards, and session-zero control |
| Monster Core | Creature traits, monster roles, weaknesses, resistances, encounter behavior, and stat-block language that Thaumaturge and cryptid stories rely on |
| Dark Archive | Psychic, Thaumaturge, Reflection, paranormal archetypes, deviant powers, mindscapes, cryptids, secret societies, cults, occult magic, and casefile structure |
That matters because Dark Archive is easy to misuse. If the GM ignores rarity and access, rare options feel ordinary. If the GM ignores creature traits, Thaumaturge loses oxygen. If the party ignores focus pressure and action economy, Psychic feels like a fragile caster with a dramatic button.
Casefile Use
The Stolen Casefiles are short paranormal adventures across several levels. Treat them as pacing models, not content to summarize in detail.
Useful casefile structure:
| Step | What to borrow |
|---|---|
| Rumor | Start with testimony, a strange report, a missing person, an impossible object, or conflicting witnesses |
| Evidence | Give players several clues, not one perfect answer hidden behind one roll |
| Site | Put the mystery somewhere with texture: settlement, ruin, wilderness, dream, cult site, lab, or memory |
| Pressure | Add time, public fear, social suspicion, a rival investigator, or a supernatural escalation |
| Revelation | Let the truth change the party's understanding before the final confrontation |
| Aftermath | Leave a scar: reputation, debt, cursed object, rescued witness, angry society, or unresolved question |
This guide does not summarize casefile twists, reproduce adventure text, list maps, or copy stat blocks. Use the book at the table for those details.
Hot take: casefiles are most useful as a GM teaching tool. They show how to make a mystery playable without making it a locked-room puzzle that fails when the party misses one clue.
What To Skip Or Delay
| Option | Delay if |
|---|---|
| Reflection | The player only wants a mechanical package and does not want identity pressure |
| Deviant abilities | The GM cannot give backlash, quirks, and spotlight enough room to matter |
| Mindscapes | The table dislikes subjective reality or the GM cannot explain changed rules clearly |
| Psychic Duelist | Psychic duels are not a recurring campaign feature |
| Pactbinder | The campaign will not enforce bargains, obligations, or consequences |
| Curse Maelstrom | Curses are rare in the campaign and the player does not want risk |
| Secret societies | The campaign has no social play, research, faction pressure, or recurring groups |
| Cryptids | The GM just wants a normal monster fight with a new name |
Skipping part of Dark Archive is not cowardice. It is how you keep the campaign from becoming a junk drawer full of haunted scissors.
Best Starting Paths
| Goal | Start here |
|---|---|
| "I want psychic magic" | Psychic, Psychic feats, psychic spells |
| "I want to hunt monsters with weird lore" | Thaumaturge, Thaumaturge feats, creature traits |
| "I want a paranormal archetype" | Dark Archive archetypes, Free Archetype, dedication feats ranked |
| "I want a rare identity story" | Reflection, session zero, secret societies and cults |
| "I want occult GM tools" | Cryptids, mindscapes, deviant abilities |
| "I want better investigations" | GM subsystems, social encounters, skill DCs, skills |
GM Advice
Dark Archive mysteries need redundancy. Do not put the whole adventure behind one secret Occultism check.
Before running a Dark Archive-heavy session, answer these:
| Prep question | Good answer |
|---|---|
| What is the first obvious sign? | A witness report, impossible corpse, strange dream, missing shadow, or recurring symbol |
| What are three clue paths? | Research, social testimony, physical evidence, magic, monster behavior, or faction records |
| What is the false theory? | A mundane explanation that is plausible but incomplete |
| What makes the threat active? | It hunts, spreads, bargains, rewrites memory, recruits, or changes location |
| What does failure change? | More victims, worse reputation, a cult advances, the mindscape spreads, or the cryptid relocates |
| What can Thaumaturge or Psychic reveal? | Creature traits, occult resonance, emotional residue, mind pressure, weaknesses, or false identity |
If the party has a Thaumaturge, make traits, rumors, weaknesses, and strange objects discoverable. If the party has a Psychic, give mental, emotional, dream, and occult phenomena room to matter. If the party has neither, the book still works, but clues need more mundane routes.
Hot Takes
| Hot take | Why |
|---|---|
| Psychic is not just an occult blaster. | The class is about cantrip identity, focus pressure, and timing the moment you push too hard. |
| Thaumaturge is the best "knowledge as combat" class in PF2e. | Esoteric Lore and implements make monster information matter without turning the game into pure trivia. |
| Reflection should be a campaign premise, not a cosmetic pick. | If identity never matters, the heritage is underused. |
| Deviant abilities are better as scars than upgrades. | Backlash, quirks, and story consequences are the reason to use them. |
| Cryptids should be investigated before they are fought. | If the party learns nothing before initiative, the cryptid is just a monster with worse lighting. |
| Mindscapes need rules clarity. | Subjective reality is fun only when players understand what their characters can try. |
| Dark Archive works best when the table feels watched before the dice hit the tray. | Unease is the book's currency. Spend it deliberately. |
Final Notes
Use Dark Archive when the campaign wants occult pressure, investigation, strange identities, and supernatural consequences. Add Psychic and Thaumaturge when players want those engines. Add the bigger weirdness when the GM is ready to make it matter.
