Kai'sa W bugged
So I was playing multible games as Kai'sa (Ap kai'sa) and I felt like my W did 0 dmg, So I looked at my W and the tooltip said that it does 0 bonus magic dmg but on the evolve part it said "100 ap needed (500 currently). I don't think that it only was a tooltip bug because my W didn't feel like it was doing dmg either. I would recommend to disable Kai'sa because this bug is sort of gamechaning.
