Heey,

We are going to play with Evelynn.
When you know how to play with her you can easily get scores like 25-5.
I usually get these scores and im going to tell you all about it!

So lets start

If your playing Eve for the first time maybe health is usefull or mana regen but if you played her many times you know that she has enough mana regen and enough health to kill.
If you already played her before you know she has 100% AP use at Ravage so when your level 3 you should have like 37 AP and ravage will do 172 damage. when you combine that with your stealth you can easily damage them without they can fight back because of stun!

Magic penetration in early game is more usefull then +5 ability power!
For more damage at lvl 2 with Ravage
For more damage at lvl 2 with Ravage
For more damage at lvl 2 with Ravage

As masteries its i­mportant that you take mana regen and cooldown reduction.
I tooke 9-0-21 because of that.
There is nothing really special about this so lets go on to items.

Early Game :

Doran's Ring First get your Doran ring for mana regen and ability power.
Health Potion Get 1 health potion so u can stay longer in lane.
As soon as you can go and buy boots. if you can affort to buy an Amplifying Tome
get it. It's now smart to just go raping.

Mid Game :
Sheen must be finished already and you got Kage's Lucky Pick.
Its now handy to finish your Deathfire Grasp
