Death of Enemies
10,000 XP
You can instantly slay your favored enemies with a single strike.
Prerequisites: Favored enemy class feature, 10 ranks in Knowledge skill appropriate to a creature’s type.
Benefit: Any time you score a critical hit against one of your favored enemies about which you have at least 10 Knowledge skill ranks, it must make a Fortitude save (DC 20 + your favored enemy damage bonus for that sort of creature) or die instantly.
Special: Creatures immune to critical hits can’t be affected by this feat.
