I get it that they let you deal more damage per hit to a boss but do they confer any additional rewards, better drops, favor points etc? If not I don't really get what the point of going through all the trouble to unlock them is.
Power attack First, if you deal more damaga you get more XP(I think) And if there are 15 weak Viking in one clan, and they couldn't defeat that boss with their normal damage, they unlock the srongest Power attack and they can deal some heavy damage. Isn't it obvious?
