Public Execution

The assassin's art of killing shocks those around him, making them feel the fear of imminent death. Whenever the assassin reduces a target to 0 hit points or kills it with his target assassination ability, he immediately makes a Persuasion (intimidate) check to demoralize all foes within 30 feet who can see the kill. If the victim was affected by the assassin's mark of death, the assassin gains a +2 bonus on this check.
