Patch Available - KMST 1.2.457

Considering how many times a minute most characters attack, I think making the skills take any % HP more than even 1 or .5 would be suicide, and kind of stupid.

try like .1 or .2(hp drain is by each cast, and not each hit, so if they had slightly longer animations for their attacks, .1 and .2 would be manageable), and since their power apparently changes when you use skills for a set amount of time, they must have some ability to sorta break the normal chain, most likely a move that heals hp.
