While playing, at random, the flight of Gaavanir stops doing damages along its fly path. Only the proximity damages stays. When the bug occurs, it lasts for all the session. Only a quit game then relaunch allows to get back a working skill.

In the meantime, Anvil's Woe seems to do some damages or 0 damage at random on series of strike. I could use it 5 times on a monster and it could be like I strike in the air or 5 times and it touches 5 times. As if the game considers the monster is not where I see him (and I have no lag).

Those problems happen sometimes in solo mode and in a two player game, whether I lead or not, I happens almost everytime, more or less fast but when it happens my character loses a lot of power with those pretty much useless/randomized skills.
