When I begin to fight the 10 people that is required of me, I try to use the Destructive Clench spell with an inferno staff to knockback and stun the enemy so that I can keep a fair distance between myself and them. the problem is that it only works about 1/5th of the time. it normally just has my character go through the motions, and then no damage animation shows up, but it does drain my mana. No damage is dealt nor is there a knockback effect dealt to the target. the bug is rather annoying because it isn't allowing me to fight using my normal 1 on 1 tactic.
