Trigger: An enemy makes an attack against your Will.

Effect: Until the end of the encounter, whenever the triggering enemy makes a melee or a ranged attack against you or any of your allies, it must make a saving throw. On a failure, it must target your enemy that is closest to it, instead of its chosen target (the enemy can attack as normal if no other enemies can be targeted). On a successful saving throw, this effect ends.
