Kai'sa W No Ap Ratio
Kai'sa's W does not use its AP Ratio no matter how much AP you have. The tooltip always displays (+0) for the Ap ratio and it does not increase the damage of the ability with AP. I have played her in 3 different games today and not a single time has the AP ratio worked. To replicate the bug just play Kai'sa in a game, it happens everytime. https://imgur.com/a/M0EgL
