Chapter 3: Classes / Animal Companions and Familiars / Familiars

Modifiers and AC

Source Core Rulebook pg. 217 2.0
Your familiar's save modifiers and AC are equal to yours before applying circumstance or status bonuses or penalties. Its Perception, Acrobatics, and Stealth modifiers are equal to your level plus your spellcasting ability modifier (Charisma if you don't have one, unless otherwise specified). It can't make Strikes, but it can use trained skill actions for skills for which it adds your spellcasting ability modifier. If it attempts an attack roll or other skill check, it uses your level as its modifier. It doesn't have or use its own ability modifiers and can never benefit from item bonuses.
