Evelynn...
the most hated champion by Riot (probably)
Everyone rages about her being nerfed and that she needs some buff.
NOT (i mean it would be nice to get the stun back but not that she really needs it) becouse she can still be op if played as she should be.
This is an old build, a little changed (just the masteries), but really really good working.

Put here whatever I use really random runes and still works very well (prefer ap/lvl marks, flat ad seals and glyphs, and flat ap or armor quints).

Masteries are reworked becouse the old build was with old masteries.
For me this is classic hybrid build (with smite mastery cos you are really gonna need as much money as you can), it can ofc. be changed with a litle cd but not necessary.

regrowth pendant is a MUST for start since you are starting with mini golems and for philosopher's. Philosopher's is good becouse you need MONEY and you aren't gonna kil many minions (explain later). OFC. these can be replaced with a little tankier items if you are too much targeted, but you should do fine.

Your q is the best dps you gonna get (after leaving stealth), so max it INSTANTLY. DONT max stealth first or e becouse q has like no cd and it is nice to have it. For golems you need q absolutely (haven't tried with e if you do send me how it passed).

Smite classic for jungling yes yes people are going to rage why you got smite and aren't a jungler.
Smite is a spell you'll use on the big minions (that litle cannon minion) to last hit it, and it is a nice to have it when killin dragon, baron or stealing those for your team.
Ignite is always a good option for hybrids.
SMITE use it ONLY on the cannon minions and ONLY when you can kill it with smite.

This build works 50/50 on ranked but on ranked ALWAYS be on your guard for wards becouse enemies will definetly buy it. Don't rush on your enemies alone like a dumbster, and don't go for kills that might lead you to death (EVEN IN STEALTH) except MAYBE if they got killing spree and you are 100% sure you'll get kill, else NO.

You'll start at the mini golems ALWAYS with this build.
Smite the big one and ignite the mini one, kill them both and use pot if needed, then go to your lane and start the killing. AS i said earlier in the build KILL THE CANNON MINIONS WITH SMITE, that's the one best reason you take it.
This is now doable without smite but not so easy.

Your team is your support with evelynn.
NEVER go first in fight, wait for tank/offtank/lanemate and then jump them.

Evelynn is 1 of my best champions and this is the build that got her to that point.
PLZ don't fail with it, and comment about how it goes with it.
Good luck and have fun!
