The condition "Target is stunned" = false failed. Its not possible to check if a target is not stunned.
I add my Fightclass file. The spell Cheap Shot shows the problem. With "Target is stunned" = false it will never be executed. Without this condition it stun, and stun and stun ....
Tested an a dummy
P.S. the fightclass update for subtlety is comming soon...dont use this file. It will updated, if it is work fine.
