Introduction
Afflictions are staged threats such as poisons, diseases, and curses. They are dangerous because they keep asking for saves after the initial exposure and can worsen if the character fails.
Copyright-Safe Scope
This is a practical guide to using afflictions at the table. It does not reproduce full poison, disease, curse, spell, item, or monster entries. Use the official books for exact stat blocks, DCs, stage text, durations, and cure requirements. Use this guide for the part the books do not do for you: deciding when an affliction is interesting, how to track it cleanly, and how to make it matter without turning the session into medical billing paperwork.
Affliction Anatomy
| Part | Meaning |
|---|---|
| Saving throw | The save used to resist or recover. |
| Onset | Delay before the first effect. |
| Stage | Current severity and effect. |
| Maximum duration | How long it can last. |
| Cure condition | How the affliction ends. |
Many afflictions improve or worsen by stage based on saving throw degree. Track stage openly unless the affliction is hidden for story reasons.

Affliction Threat Rankings
| Affliction Type | Best Use |
|---|---|
| Combat poison ● | Immediate urgency, especially when the target has weak Fortitude or is already pressured by conditions. |
| Exploration disease ● | Travel pressure, settlement trouble, wilderness consequences, and downtime choices. |
| Curse ● | Story consequences, divine or occult fallout, haunted treasure, broken vows, and hard choices. |
| Slow poison ● | Suspense, ambush setup, social intrigue, and "something is wrong" scenes. |
| Repeated minor disease ● | Good for attrition campaigns, weak as a boss replacement. |
| Hidden affliction ● | Great for mystery, risky if players feel denied information they needed to act. |
The ranking is not about raw numbers. It is about decision pressure. A poison that changes a turn is scarier than a disease that technically exists but never changes what anyone does.
Poison, Disease, Curse
Poisons often hit fast and punish Fortitude. Diseases are slower and can shape travel, downtime, and recovery. Curses are magical and often require specific countermeasures rather than ordinary treatment.
Poison
Poison belongs in action scenes, infiltration scenes, monster fights, and alchemical play. It works best when the exposure has a visible source: fangs, needles, fumes, darts, blades, venom sacs, tainted wine, or a suspiciously confident assassin. The counterplay should be real too: Medicine, antidotes, alchemical items, consumables, Fortitude investment, positioning, and monster knowledge.
Disease
Disease is usually better as adventure pressure than as a surprise combat gotcha. Use it for polluted ruins, plague towns, cursed swamps, undead sites, sewer crawls, monster lairs, and long travel. The interesting question is not "can the disease hurt someone?" It is "will the party spend time, money, spells, favors, and risk to stop it before the next scene?"
Curse
Curses should feel different from poison and disease. They can be divine, occult, ancestral, item-bound, location-bound, or consequence-driven. A curse is often best when it has a narrative handle: return the stolen thing, satisfy the spirit, expose the liar, break the pact, cleanse the shrine, or confront the source. If the only counterplay is "roll until the number improves," the curse is wearing a costume and not doing the job.
Player Core 2 Examples
Player Core 2 adds many ancestry options that care about poison, disease, drained, sickness, and undead or void-adjacent pressure. Hobgoblin, ratfolk, lizardfolk, tripkee, catfolk, and kholo options can improve saves or outcomes against afflictions. Alchemist support also makes poison and antidote play more visible.
This also affects class planning. Alchemists make poison, antidote, elixir, and consumable access more common. Champions, Clerics, and Oracles often pull curses and sanctified enemies into the spotlight. Druids and Rangers make disease, venom, wilderness recovery, Nature, and Survival more campaign-facing. Investigators make afflictions better because they can turn "you feel bad" into clues, suspects, reagents, and leads.
GM Core Use
Afflictions are strongest when they create decisions. Do the characters press on, spend resources, seek treatment, retreat, or risk the next stage? If the answer is always "we wait until it ends," the affliction is not adding much.
Tracking Procedure
Use one compact tracker per afflicted character or creature.
| Tracker Field | Why It Matters |
|---|---|
| Source | The table should know whether this came from a monster, hazard, item, environment, spell, or story event. |
| Save and DC | The player needs to know which defense is under pressure unless the affliction is intentionally hidden. |
| Onset | Prevents the common mistake of applying effects too early. |
| Current stage | The stage is the affliction's actual current state. The name is just the label on the bottle. |
| Interval | Tells everyone when the next save happens. |
| Maximum duration | Prevents endless drifting consequences. |
| Treatment plan | Medicine, spells, items, downtime, retreat, research, or story cure. |
The GM should announce when the next save is due. The player should track visible effects and ask what treatment options their character understands. Shared bookkeeping is faster than making one person run a spreadsheet in the corner like a cursed accountant.
Recovery And Treatment Priorities
| Priority | What To Try |
|---|---|
| 1 | Stop new exposure. Leaving the poison cloud, killing the venomous monster, removing the cursed item, or escaping the disease source matters first. |
| 2 | Stabilize the character. Use healing, defensive actions, condition removal, or retreat if the affliction is likely to down them. |
| 3 | Identify the threat. Use Medicine, Nature, Religion, Occultism, Arcana, or Recall Knowledge as appropriate. |
| 4 | Use the right support. Antidotes, antiplagues, healing magic, divine aid, downtime care, and campaign-specific cures all have different niches. |
| 5 | Decide whether to press on. If the next stage can ruin the next fight, leaving may be the optimized play. Heroism sometimes looks like going home and washing your hands. |
Afflictions In Combat
Combat afflictions need clear timing. If a poison applies on a hit, the table should know when the first save happens, whether onset delays the effect, and when future saves occur. Conditions from afflictions connect directly to conditions in combat, persistent damage, dying and death, save progression, and actions and activities.
The strongest combat poisons do one of three things:
- Punish a weak save.
- Add a condition that changes the target's next turn.
- Create a clock the party cannot ignore.
If the poison only adds small delayed damage after the fight is already over, it may still be flavorful, but it is not doing much tactical work.
Afflictions In Exploration
Exploration afflictions should create route, time, and resource decisions. A swamp fever, haunted tomb curse, sewer plague, corrupted ration supply, or monster-spore exposure can push players toward Survival, Medicine, Crafting, GM environment, hazards, and subsystems.
Do not hide every lever. Players should be able to make informed choices: travel faster and risk worsening symptoms, slow down for care, spend consumables, search for ingredients, ask a settlement for help, or turn back. Afflictions are better when the party argues about priorities in-character instead of arguing about whether the GM forgot the interval.
Common Mistakes
Forgetting onset. Some afflictions do not hit immediately.
Forgetting stages. The current stage matters more than the name.
Using afflictions only as punishment. They work best as pressure, clues, hazards, and consequences.
Ignoring treatment options. Medicine, spells, items, and downtime can matter.
Stacking mystery on top of bookkeeping. Hidden afflictions are fine, but if the player cannot infer symptoms, timing, or counterplay, they are just losing agency in slow motion.
Using curses like poisons. If a curse has no story logic, moral hook, place, object, spirit, deity, or occult source, it is probably just a magical penalty with better branding.
Running Afflictions Round By Round
Afflictions are easiest when the GM tracks five things in one place: onset, stage, save DC, interval, and maximum duration. At the table, announce the current stage effect, say when the next save happens, and remind the player what success or failure will change. That keeps poison and disease from becoming a hidden bookkeeping tax.
Player Core makes stages matter because damage and conditions apply when the creature reaches that stage. Some conditions can outlast the affliction itself, and virulent afflictions require more work to reduce. That means the dramatic question is not only "did you fail the save?" It is "how long can the party afford to ignore this?"
Player Core 2 Pressure Points
Player Core 2 adds more characters who care about afflictions before they hit the sheet. Alchemists can make poison, antidote, elixir, and item access a campaign feature. Hobgoblins and other martial ancestries often interact with fear, poison, and battlefield endurance. Dhampir and Duskwalker concepts change how players think about undeath, vitality, void, and consequences after death. Champions and Oracles can turn curses, sanctification, and divine opposition into story-facing affliction pressure.
GM Core Campaign Use
Use afflictions to change priorities, not to quietly drain fun. A disease in town should point toward Medicine, research, NPC favors, downtime, and cost. A poison in combat should create urgency now. A curse should ask for story action: remove the item, make amends, confront a spirit, return stolen treasure, or seek a specialist. GM Core pacing tools help decide whether the affliction is an encounter complication, an adventure clock, or a campaign problem.
Monster Core And Monster Core 2 Use
Monsters make afflictions feel dangerous because the exposure is embodied. Venomous creatures, undead, fiends, aberrant horrors, oozes, vermin, diseased beasts, and cursed guardians all tell the party what kind of problem they are facing before the save is rolled. Use creature traits, stat blocks, monster families, and encounter use to decide whether the affliction is the main danger or a supporting complication.
Afflictions should also affect encounter balance. A monster that applies a nasty ongoing disease or poison can overperform against a party with weak Fortitude, limited Medicine, no consumables, or no time to rest. A party with strong Medicine, divine support, antidotes, and scouting may trivialize the same threat. That is not a bug. That is the party being prepared.
Character Build Notes
| Build | Affliction Lesson |
|---|---|
| Medicine specialist | The party's best defense against affliction spirals. Bring skill feats and downtime plans. |
| Alchemist | Makes poison, antidote, antiplague, and consumable logistics central instead of incidental. |
| Cleric | Divine magic and Religion can turn curses, undeath, and disease scenes into class moments. |
| Druid | Nature and primal support fit venom, wilderness disease, plants, animals, and environmental causes. |
| Champion | Works best when afflictions are tied to holy, unholy, fiendish, undead, or oath-facing pressure. |
| High-Fortitude martial | Often resists the first hit, but should still respect stage progression and backup treatment. |
| Low-Fortitude caster | Needs scouting, positioning, consumables, and allies. "I hope the snake misses" is not a medical plan. |
GM Encounter Templates
| Template | How To Use It |
|---|---|
| Venom ambush | One or two poison sources, terrain that makes retreat costly, and visible treatment options after the fight. |
| Plague settlement | Social encounters, Medicine checks, scarcity, NPC stakes, and a clock before symptoms worsen. |
| Cursed treasure | A tempting reward with a visible drawback, investigation path, and story cure. |
| Corrupted wilderness | Disease or poison exposure tied to travel choices, weather, hazards, and Survival. |
| Undead aftermath | Void, drained, disease, fear, and wounded consequences connected to dying recovery. |
Player Checklist
Before walking into a poison, disease, or curse-heavy campaign, answer these:
- Who has Medicine?
- Who can identify magical or occult causes?
- Do we own antidotes, antiplagues, or other consumables?
- Who has strong Fortitude?
- What is the retreat plan if symptoms worsen before the next fight?
- Does the GM expect curses to require story cures, spell cures, or both?

Hot Take
An affliction that never changes player behavior is just delayed bookkeeping. The spicy version: if your poison is less interesting than a goblin with a door and a grudge, rewrite the poison.
