I've seen this feat debated a lot and want to know your thoughts on it. Inexorable Shroud reads as follows: "If an enemy is reduced to 0 hit points while it is subject to two or more of your shrouds, you can move up to two shrouds to a different enemy within 5 squares of you." This feat was published in dragon magazine 401.
The part I'm concerned with is here: Before you make an attack roll against the target, you choose to invoke either all your shrouds on it or none of them. If you invoke your shrouds, the attack deals 1d6 damage per shroud, minus one shroud if the attack misses, and all your shrouds then vanish from the target.
So the question is does the feat trigger before they are able to vanish from my target since the shroud damage is additional and not extra? Am I allowed to move two shrouds from one target to another due to inexorable shroud if my target has died even after invoking them? Assassin's shroud was published in dragon magazine 379.
