Recognize Spell [reaction] Feat 1General Secret Skill Source Player Core pg. 261 2.0PFS Note The DC to Recognize an Uncommon or Rare spell (page 261) should be the normal DC +2 or +5 based on rarity and spell level.
Prerequisites trained in
Arcana,
Nature,
Occultism, or
ReligionTrigger A creature within line of sight casts a spell that you don’t have prepared or in your spell repertoire, or a trap or similar object casts such a spell. You must be aware of the casting.
If you are trained in the appropriate skill for the spell’s tradition and it’s a common spell of 2nd rank or lower, you automatically identify it (you still roll to attempt to get a critical success, but can’t get a worse result than success). The highest rank of spell you automatically identify increases to 4 if you’re an expert, 6 if you’re a master, and 10 if you’re legendary. The GM rolls a secret Arcana, Nature, Occultism, or Religion check, whichever corresponds to the tradition of the spell being cast. If you’re not trained in the skill, you can’t get a result better than failure.
Critical Success You correctly recognize the spell and gain a +1 circumstance bonus to your saving throw or your AC against it.
Success You correctly recognize the spell.
Failure You fail to recognize the spell.
Critical Failure You misidentify the spell as another spell entirely, of the GM’s choice.
