yes, the free 0.02pc version. there is no error, just blackness instead of a combat pose, so it switches from nothing to attack art and back.
the grind wasn't too bad, just repetitive for mentioned reasons. maybe make it a bit more gradual though, the final jump from 100 to 300 feels out of place. and you have some odd moments when you have enough hp left to finish a fight, but have to run back since you have no more mana to keep attacking.
