Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Build for anivia where you can get more or less 1009 ability power. I've seen players use this build and it is very scary. It probably needs some tweaking though to get the 1009 ability power. This build is just an estimate of what i think the build should be to get such a high AP. So please don't flame me saying i don't know how to play anivia, because i know i don't. Anyway have fun and all comments are welcome!
