Syndra AP

Hey guys i just thought this would be important (probably not). But i was testing out Syndra since she was on free rotation in practise mode and i wanted to see how much MR can i rip from a target during a ult so i decided to use 4 Death caps and a abyssal mask and a wits end. But when i looked at my AP it kept jumping from 696 AP and 877 AP (Values may change depending on your runes ETC. I further saw that if you have abyssal mask it keeps making your AP jump up and down.

Hopefully you can fix this so it doesn't get abused in some way. Thank you
