Something is causing 2 handed weapons to give insane damage boost. I don't know what the cause is, but I have gotten the bug and so have others. It causes you to do insane damage. It may have something to do with momentum, rally, executioner damage bonus, flawless dawnbreaker damage bonus, 2h sword damage bonus, or something else. I have seen a nightblade with the bug hit ambushes for 15k, surprise attack for 20k, and more against heavy armor.
