Hello everyone, I'm YzzR. This is basically my build of how I play evelynn. Now as you know, any of these can be switched out for something else. It's how i enjoy playing her.

I start with Greater mark of Desolation for armor penetration, Then complimenting that with Glyphs of Celerity Making your shadow walk Spammy in a sort. Greater seals of Resilience for more armor and Quint of swiftness for faster ganking lanes.

I basically set up a mastery page for more gold, and cooldown. This will make you very powerful early game and able to let you gank lanes harder. I also bought Extra gold at start making you able to buy One more health potion meaning you can gank lanes more instead of at your base healing.
