Afflictions

Source Player Core pg. 430 2.0
Diseases and poisons are types of afflictions, as are curses and radiation. An affliction can infect a creature for a long time, progressing through different and often increasingly debilitating stages.

Format

Source Player Core pg. 430 2.0
Whether appearing in a spell, as an item, or within a creature’s stat block, afflictions appear in the following format.

Name and Traits

Source Player Core pg. 430 2.0
The affliction’s name is given first, followed by its traits in parentheses—including the trait for the type of affliction (curse, disease, poison, and so forth). If the affliction needs to have a level specified, it follows the parentheses, followed by any unusual details, such as restrictions on removing the conditions imposed by an affliction. If no level is listed, the affliction matches the level of the creature, hazard, or item causing the affliction.

Saving Throw

Source Player Core pg. 430 2.0
When you're first exposed to the affliction, you must attempt a saving throw against it. This first attempt to stave off the affliction is called the initial save. An affliction usually requires a Fortitude save, but the exact save and its DC are listed after the name and type of affliction. Spells that can cause an affliction typically use the caster's spell DC.

On a successful initial saving throw, you are unaffected by that exposure to the affliction. You don't need to attempt further saving throws against it unless you are exposed to the affliction again.

If you fail the initial saving throw, you advance to stage 1 of the affliction and are subjected to the listed effect. On a critical failure, after its onset period (if applicable), you advance to stage 2 of the affliction and are subjected to that effect instead.

Onset

Source Player Core pg. 430 2.0
Some afflictions have onset times. For these afflictions, once you fail your initial save, you don’t gain the effects for the first stage of the affliction until the onset time has elapsed. If this entry is absent, you gain the effects for the first stage (or the second stage on a critical failure) immediately upon failing the initial saving throw.

Maximum Duration

Source Player Core pg. 430 2.0
If an affliction lasts only a limited amount of time, it lists a maximum duration. Once this duration passes, the affliction ends. Otherwise, it lasts until you succeed at enough saves to recover, as described in Stages below.

Stages

Source Player Core pg. 430 2.0
An affliction typically has multiple stages, each of which lists an effect followed by an interval in parentheses. When you reach a given stage of an affliction, you are subjected to the effects listed for that stage.

At the end of a stage's listed interval, you must attempt a new saving throw. On a success, you reduce the stage by 1; on a critical success, you reduce the stage by 2. You are then subjected to the effects of the new stage. If the affliction's stage is ever reduced below stage 1, the affliction ends and you don't need to attempt further saves unless you're exposed to the affliction again.

On a failure, the stage increases by 1; on a critical failure, the stage increases by 2. You are then subjected to the effects listed for the new stage. If a failure or critical failure would increase the stage beyond the highest listed stage, the affliction instead repeats the effects of the highest stage.

Damage and Conditions

Source Player Core pg. 430 2.0
Any damage listed for a stage happens immediately when you reach that stage. Conditions affect you when you reach the stage and last for their normal duration. For instance, if you were drained for an affliction with a maximum duration of 5 minutes, you remain drained after the affliction ends, as normal for the drained condition. A condition that automatically changes its value or ends under certain circumstances, like frightened, still does so. Any condition that doesn’t have a default duration, such as clumsy or paralyzed, lasts as long as you’re at that stage unless noted otherwise, as do any penalties or any other effect of the stage that doesn’t list a duration.

Multiple Exposures

Source Player Core pg. 430 2.0
Multiple exposures to the same curse or disease currently affecting you have no effect. For a poison, however, failing the initial saving throw against a new exposure increases the stage by 1 (or by 2 if you critically fail) without affecting the maximum duration. This is true even if you’re within the poison’s onset period, though it doesn’t change the onset length. If the poison does not have an onset time or it’s already elapsed, you are immediately subject to the effects of the new stage.

Virulent Afflictions

Source Player Core pg. 431 2.0
Afflictions with the virulent trait are harder to remove. You must succeed at two consecutive saves to reduce a virulent affliction’s stage by 1. A critical success reduces a virulent affliction’s stage by only 1 instead of by 2.

Removing Afflictions

Source Player Core pg. 431 2.0
Apart from waiting them out, afflictions can be removed through certain uses of the skills and spells. The Treat Disease and Treat Poison uses of Medicine are commonly used to treat those afflictions.

The cleanse affliction spell is also available to most spellcasters. Spells that counteract conditions at the source, such as sound body, can also be effective against diseases and poisons that cause those conditions.

Curses are trickier, requiring solutions that specifically mention them, such as a 4th-rank cleanse affliction or the Break Curse skill feat.
