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.
Evelynn's ability to stealth can make her very annoying to some players. This build has some major risk but with three stacks of sunfire cloak you can harass your enemies by just staying in stealth around them. This build can really work if played right.
3 sunfire cloaks gives you a lot of passive damage
high armor and magic resist
Good AP and heath
