Terrifying Killer (Combat)

You inspire fear in those who witness you kill.

Prerequisite(s): Intimidate 5 ranks, death attack class feature

Benefit: Whenever you successfully slay or paralyze an opponent with a death attack, you may take a swift action to inspire fear in one ally of that opponent within 30 feet who witnessed you make the attack. That creature must make a Will saving throw (DC equal to the DC to resist the death attack) or become shakened for a number of rounds equal to your assassin level. If the creature has 5 or fewer hit dice, it becomes frightened instead.
