Chapter 11: Crafting & Treasure / Alchemical Items / Alchemical Elixirs

Mutagens

Source Core Rulebook pg. 546
These elixirs, indicated by the mutagen trait, temporarily transmogrify the subject’s body and alter its mind. Typically, only alchemists have the expertise to craft mutagens, and some say they are the only ones reckless enough to use them.

A mutagen always conveys one or more beneficial effects (listed in the Benefit entry) paired with one or more detrimental effects (shown in the Drawback entry). Mutagens are polymorph effects, and a subsequent polymorph effect attempts to counteract an existing effect; the counteract check for a mutagen uses the item’s level and a modifier equal to the that level’s DC – 10, as found on Table 10–5: DCs by Level.
