Like the Crash of Battering-rams:
Playable on a strike. If the strike is successful, the wounded character's body is reduced by one until the end of turn for every complete increment of 5 the strike was successful by (subtract the character's prowess plus dice roll from the strike's prowess, divide by five, and drop any fractions). "A sweep of his tail and the roof of the Great House crumbled and smashed down."-Hob
