Tired of Guessing how much damage Kai'sa will do with your crazy build? I made a calculator.

So I was a little bored and made a calculator with Excel to test how much damage each ability will do with your item build. She scales with a lot of different stats so I decided to automate things a bit. Just input you level, AP, AD, AS, and ability rank to check out some good ol data. Kai'sa does 45% missing hp damage with her passive at lvl 16 and 1k AP o.O

Sorry if I made a mistake somewhere, I made this for myself but thought I might as well share if someone wanted to try it out as well. The formulas will not stay current so you will have to update them yourself if you want accurate results if/when Kai'sa's numbers change from a patch. Let know if you have any questions or maybe want me to run some numbers for you :)
