Shadow's Inexorable Grasp

Paragon Tier
Prerequisite: 11th level, Assassin, assassin's shroud power
Benefit: When you are reduced to 0 or fewer hit points, any creature within 10 squares of you with at least one of your shrouds on it takes damage from your assassin's shrouds as if you had missed it with an attack, and your shrouds vanish from the target.
