(General)
You can detect the mystic specialty of a foe.
Prerequisites
Intelligence 13, ability to cast detect chaos, detect evil, detect good, detect law, or detect magic.
Benefit
When you use any of the spells listed in this feat's prerequisites to detect a creature's alignment or its magic, you have a chance of detecting what spellcasting expertise it has. After you observe a creature with the detect spell for 3 rounds, it must make a
Will Save (DC 10 + 1/2 your caster level + your
Intelligence modifier). If it fails the saving throw, you learn what bloodlines, domains, hexes, schools, or mysteries (if any) the creature possesses. If the creature makes its save, it is immune to the effects of this feat for 24 hours.
