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.
I think evelynn's potential as a top laner is underestimated and is definitely Worth the try. I often play evelynn in ranked and normal games and get quite a good KDA ratio with her whenever i play jungle or top. Even if she is quite squishy her burst is definitely Worth a try and can mostly kill any enemy with less than 2k hp in just a few hits.
you'll want to start with the corruption potion and just farm your minions till you reach level 4 or if the enemy is squishy you can play a little more agressive from the start just make sure you don't end up ganked or without mana.
If you have a comfortable start you can try to kill the enemy jungle if he is doing red when you're level 2.
after you get some money go for 2 aether wisps it gives you some movement speed and some ap.
When you're mid-game you should go for lich bane and ludens echo. it will give you some good ap and a pretty insane burst combined with the thunderlord. you're combo will be A-Z-E without ult and remember to Attack only from invisibility and always from behind dont run in you're squishy an dwill get killed. at this point you do around 3/4 of enemy hp if they're squishy like adc or assassin's.
You dont need boots because you have you're Z and the bonus from you're items. you're aren't tanky enough to dive in however, trying to engage with you're ult is Worth it it'll destabilize the whole enemy team and gives you're team the chance to dive in and get some kills. you're goal will be to kill the squishy ones or kill the ones that are running. if you're team gets pushed however you can stay behind and spam you're a to slow enemies and force them to stop chasing just don't get yourself stunned or you're dead.
