Arrow of Destiny
Bard Attack 29
What this arrow pierces soon falls.
Ranged weapon
Attack: Charisma vs. AC
Hit: 2[W] + Charisma modifier damage, and the target is affected by your arrow of destiny (save ends). While the target is affected by the arrow of destiny, whenever the target is hit by an attack from an ally, you can use an immediate interrupt to make the attack a critical hit.
Miss: Half damage. If the target is hit by an attack from an ally before the end of your next turn, you can use an immediate interrupt to make the attack a critical hit.
Arrow of Destiny is a daily power available to bards at the 29th level.[AP:17]
