The manner in which you deal with fallen foes sows doubt in the hearts of survivors.
Prerequisite: Str 15, Cha 11, Cleave, Kill Count, Killing Blow, Power Attack.
Benefit: When you make a successful coup de grace attack against a target of at least ½ your HD total, all opponents that witness the kill must make a Will saving throw (DC 10 +½ your character level +your Charisma modifier) or become shaken for the rest of the encounter. Creatures with higher HD totals than your own are unaffected. This is an extraordinary fear effect.
Special: A fighter may select Brutality as one of his fighter bonus feats.
