Stuns the target and applies a debuff. The values are not published. Seen in play as a target-selection tool rather than a damage one: the walkthrough shrieks the weaker of two enemies to take him out of the fight briefly, so the harder opponent can be dealt with one-on-one. That is the use worth planning for in a game where being surrounded is the real threat and blocking only faces one way.
