Thanks a lot, I appreciate and I'll practice with it for a while before I get back to you. :P
/EDIT: Lucky works perfect as an active skill and gives the effect of Wind Walk but when changed to passive, doesn't. I take it that buff effects can only work as active effects? Another thing is, the name of the skill doesn't change even if the skill name in .xml has been, so looks like this can't be modified without the code change? The same thing with adding a custom skill to all classes, right? Can only be done through code edit?
