Hey guys, I'm a really good Evelynn player on NA servers. I don't play ranked, but I have a huge amount of eve games played. I felt in love with her because you can do a level 2 invade super easily. With a kill, you can get his red or blue, depending of the buff he was on. Then you can gank lvl 3. You have 1-2 levels ahead because of the new jungle xp. You are fed, tank, deal so much damage and they never know where you are.

Excuse the fact that this guide won't be as beautiful as others. It's my first one and I suck at making a text look good... I give you information and you do what you want with it.

I could tell you alot about this, but I will go with the short version.

AP Glyphs : The main reason for this is that Evelynn depends on her early game to perform well late game. With a bit of ap early, she will be able to kill enemies faster during ganks and invades.
AD Marks : Her main damage is AD. The bit of AP you get if to kill squishies but you will need AD. It will increase your early game jungle clears because your ERavage
Armor Seals : Really good as a jungler. Reduces jungle damage. Also, there is always at least ONE AD champion so you are sure this will be useful.
CDR Quints : This will allow you to spam Q and teamfight more often. (Ult is a must in teamfights)

I choose thunderlord's because it is the best assassin mastery. If you need more mobility and less damage (Ex. Illaoi) then I would suggest you to do stormraider's surge. Deathfire is also OK if you go AP but thunderlord's and stormraider's are way better if you go AD.

There is so much combinations.... On AD build, titanic hydra is a must. On AP build, hextech item is a must too. You can get protobelt if you need mobility and gunblade if you need damage.
