Dreadful Carnage

Feats

Slaying an enemy demoralizes your other nearby foes. Benefit: Whenever you reduce an enemy to 0 or fewer hit points, you can make a Persuasion (to intimidate) check to demoralize all enemies within 30 feet as a free action. Enemies that cannot see both you and the enemy you reduced to 0 or fewer hit points are unaffected.
