Abilities 16 of Viking
You trigger an Avenging ability immediately after being attacked. The attack must strike you, but you may block, counter, or apply immunity normally. You deliver the effect by swinging a weapon at the attacker.
You cannot attack, move, or use abilities other than speaking so long as the user holds you. If the attack was delivered in melee, the user must hold their weapon on you. Otherwise, they must hold a hand up toward you. The effect ends if you are hit or the user attacks, moves, or uses an ability other than speaking.
