This guide is not nearly finished yet. Just posting it for a first look to that master summoners to tell me what to add, what to make better and that stuff... Just give me a feedback. You can see what I've ment to do with this guide in section The Paths.
Just look at it and please comment.

Hello summoners, and welcome to my first guide for my first champion... So let's get started!
I started playing LoL about half a year ago, and I don't play it everyday all day long, so I'm not 30 yet, and I don't pwn every game with any champ. But don' worry. Even if I am not 18 yet and my english is not perfect you don't need to -1 my guide yet...
"Why" you ask?...
First:
Eve was my officaly first bought champ, who kicked the living horse**** out of lvl 1 summoners and bots. After some levels I got kicked back... The hard way. So I left this beauty all alone for some time...
Second:
Yep. It would realy be some time if Riot wouldn't decide to break my heart by torturing her until she lost her stun... She is the sort of a carry champ who needs the ****load of items until she starts to dominate alone except of killstealing all the way, and stun helped her A LOT. And I realy tought she was broken...
Third:
Until that same Riot blessed us with whole new and exciting map called: DOMINION.
Fourth:
So I was very interested in this map and got in touch with some breaking news:
Moar GOLD > moar ITEMS > good CARRY.
Fifth:
So I decided to make a MOBAFIRE account and make that guide once and for all.
Sixth:
Well who am I kidding with... Lets just START THIS!

Evelynn's origins are shrouded in mystery - a mystery she herself helps to perpetuate. What everyone does know about Evelynn, however, is that she is one of the most skilled assassins in Valoran. It is clear upon first meeting her that she is not quite human. Some theorize that she was cursed with a mild form of fantastical vampirism as a child. Supporters of this theory contend that her ability to sap the very life essence of her opponents on (and off) the Fields of Justice, while still being able to tolerate direct sunlight, would account for this belief. There is some evidence that Evelynn originally came from the Shadow Isles - the mysterious island located northwest of Valoran that is eternally blanketed by a thick, unnatural fog. It is thought that the Shadow Isles are home to countless forms of undead, though no one seems eager to perform the exploration necessary to find out the truth. Evelynn neither confirms nor denies her connection to Shadow Isles.

The power brokers of Valoran know that Evelynn's services come at the highest of premiums, and her recent addition to the League of Legends indicates that her ambitions are growing. Her savagery on the Fields of Justice has been so great that new rumors about her origins are now circulating. The most popular one - an abuse of magic as a child morphed her into the hungering beast her opponents see on the battlefield - always makes her smile when hearing it... an act that bares her razor-sharp fangs and teeth. Evelynn now curries favor from League summoners, gaining influence for reasons known only to her. While the nature of her plans- much like almost everything else about her - remains unknown, there's little doubt that those plans are now set on the world stage.

''There is little mystery about her to me - she is the ultimate predator.'' - Jax and Necrosiss

...

So yeah... Now you know that she is a bit*hy-assassino.

Yep, I said I pwned newbies by Eve... so that newbies were pwned apx 10 games... Nothing more. So I wasn't realy good. he was just OP. And then the nerf and *puf* 'Eve is broken.' 'Eve sux.' 'Better go delete her.'... Who would just try her again, not to mention who would even get her in front lines in ranked game and risk his much needed victory.
But since DOMINION came out, because of the reasons mentioned in my first chapter, my ex-first girlchamp became viable too. Firstly I thought she would be just a *****y CP-stealer and backstaber, and then I realized that in all that half-year time I learned a lot about not beeing greedy, beeing a squish, and so on, and without stun she is almost as she was. Realy. And after that I played her A LOT, so I'm not that guy u just saw with Eve... Now I grew in that guy that gets 20/0 in loosing game and wins it solo and u tell your friend Johny: So WHAT THE F***! Or wins Dominion when loosing 20/250 and you report me to riot for a hacker-cheater-noob-something.
Yep, I got very skilled, learned how to kill, when to drop in and out, how to scout, how to steal golem, dragon, blue, red or even BARON with a silly Shadow Walk- Smite- Flash combination and I bet my math teacher that you can dominate too.

The Pros:

- You are fed - you win.
- They overextend - your kill.
- Making enemies play passive just because you are not on map.
- You can be everywhere in the matter of seconds, so if you use your stealth, enemies will
make their pants dirty.
- EPIC bursts with short CD.
- Maybe the best ganker.
- Surely the best creep-stealer.
- If you learn her, she will pay back. In trophies.
- Ability to get in and out of fight very fast with full health and a kill.
- Multiple ways that include jungling, roaming, AP, AD and hybrid, pointstealer in Dominion
- And much, much more...

The cons:

- Worst early game because of little to no dmg.
- Unfed serves just as scout or after-combat assasin which is NOT very good.
- Stealth can be countered by good players buying Oracles and Wards, but if you have your
own Oracle, you can effectively destroy their wards and make their cash burst in 3 hits
- In-combat stealth can be countered by dots very effectively.
- Focused A LOT....
- Item dependant like ****ing ****ed ****er's ****... That's why she is so good in
Dominion.

I am the kinda person who likes to make things perfect, so this guide will feature most best paths on The Widowmaker.
1. The Dominionator:
The guide about dominion, how to dominate in kills OR objectives. Builds 1. and 2.
2. The Nightwish:
The guide about AP Eve. With noobpwn Mejai's Soulstealer system or ranked AP with more survivability. Builds 3. and 4.
3. The Nightclaw:
The guide about AD Eve. Again noobpwn system with Sword of the Occult or more sustained AD survivability. Builds 5. and 6. (1. in team 2).
4. The Assassino All in One:
Hybrid Evelynn guide where you can use her full potential along with your own skill and item actives to make perfect assasinations. Builds 7. and 8. (2. and 3. in team 2).
5. The Puma:
The guide about Eve jungling. Eve IS NOT the best jungler out there, but she is one of the best gankers, so this makes for the naileating early. This is just my way of playing jungle Eve, so you it will only help you at playing your own.

Hmm... There isn't much to discust. You must take 1 point in early Hate Spike for farming and sustaining dps. Then your stealth Shadow Walk will be very happy with fast 2 points, because you need 20 sec stealth. More is too much because you dont need slow that much and more than 20 sec stealth means that you are doing something wrong. CD reduction is nice but you have to max your damage first. The main leveling ability (which is not the main DPS - in AP build that place takes your Hate Spike and in AD... well AD) is a burst with healthy range a little more than melee that calls itself Ravage. Yep its a slash with claws which makes your other attacks and Hate Spike more effective for long 5 seconds. So with any AP or Hybrid build you have to max E and than Q, because it costs too much for early game, but with AD you go for W and E simultaneously and max Q last. You take ulti whenever you can because of its allaroundness. Agony's Embrace is good for chasing, escaping (very fast if combined with Ghost), OP AD because of attack speed boost, having an advantage over any other champ if they drop into grave fast, because of auto cooldown refresh, it's good for turret diving because if you kill a champ you get a healthy amount of health, you can kill entire team solo if killed so fast that passive heals you for a ****load of health.... But the only coon with abilities I see Eve's passive. Well it fits in nice for ganking but it's certainly not the Rebirth or Pyromania or something like that. It helps a small bit early game but it is nearly usseless late game. It would be cool if it would work for jungle creeps too =D

Before:

You HAVE to scout; that's just what you are. You look for the enemies, you know how many are there, you look for ganks, you look for recallers and kill them, you look for low hp-ers and kill them, than run. You must be 120% sure that you can use your ulti for a safe kill, because you would miss it A LOT.

In:

In a combat the main thing is to go in and out and kill. You are NOT a tank or fighter to be in a front lines. You are NOT a kinda mage that would hammer them from a distance, but you CAN innitiate one or two opponents when you have someone with you, very good, you CAN kill more of them IF you know them AND know they don't stand a chance, you CAN and MUST jump on carries and squishies and eat their brains and hearth and livers and all that stuff. You MUST NOT attack a tank in teamfight and you MUST not innitiate a teamfight. You must learn to use your ulti before enemy champ dies. Anywhere and anytime, because it's cooldown WILL refresh, and you WILL gain an epic speed and attack speed burst for a short time... For FREE!!! That is very good skill when you know how to use it. Initiate one opponent with Ravage for more damage and two of them with Hate Spike because of a slow from Shadow Walk.

After:

You are assasin, so what are you waiting for. If you see low HP enemy just go and squeze the **** out of them. You have your ulti to help, so if you are not a complete noob you will get a kill, or double, or triple, or quadra... OR PENTA. After acing them you go to push a lane and destroy a tower, get a BLUE, RED, DRAGON and especially a BARON.

The Dominionator

For this chapter click on first build.
The Dominionator is a build for Eve players in Dominion who like to keep their enemies in their base. Very similar to good Shaco or maybe even a Teemo. For items you build your boots first because you just need that upper point. And with Ghost and Speed Shrine against a slow team, you can get it by yourself. If not, you can buy Blasting Wand and Boots. At start always have a spare Health Potion because it keeps you on the field longer, so you can get more points and defend them for a longer time. The first real item after Mobility Boots is your most needed one for surviveability out of insane hp boost, AP and one of the best passives for me - the slow. Rylai's Crystal Scepter is insane early boost for Dominion on pretty much any AP champ because you DON'T NEED THAT MUCH MANA and it isn't the most expensive item out there. Then you rush your bread and butter dps item: The evil Lich Bane. When you start building your Rabadon's Deathcap the game ussualy ends. But if the enemy team is resisting your epic assasinations then there is time to get to real stuff. If they run you go fot Hextech Gunblade and if they stack MR you go for your own copy of Void Staff. I would recommend the Void one just because in dominion there is no time to kill minions and greatly benefit from Gunblade's life steal and spell vamp. For the end I would ussualy say that Guardian Angel is that stuff, that makes your K/D ratio even more surprisingly flawless. You have stealth, Ghost and Flash to make that item even more effective for escaping 100% deaths.
Well now you say... What about gameplay?
The main thing there is to CAPTURE. Even if everyone in your team goes 50/flawless and you don't control any command point you WILL loose. So the main thing is to CAPTURE. You MUST backdoor them whenever you can to get a capture point or two and defend them from a distance. You MUST be stealthed for the most time you can or you WILL get killed A LOT. By dominating the field and beeing fed just a little bit, you can LOCK your enemie's base and they surrender. That means that as soon as they get out you and/or your team kill them or make them return back. And Eve is one of the best champs to do that. That would be pretty much it... just remember: CAPTURES > DEATHS > KILLS > RELICS

The Conqueror

For this chapter click on second build.
Well it seems pretty odd.. I know. But it's actually viable. More than that. With skill a capture-only champion gets the game on a whole new level. You win the game with no combat, just capturing and a little defending, your team defends that for you. You've probably seen the capture-only Rammus in Dominion, and if you haven't... Well when you will see him in opposing team, you will hit your head with your keyboard because no matter what you will do, he will have his 3rd point always. Eve is pretty much the same. Althrough loosing against Rammust in all around mobility and gaining immense strenght with stealth. Well you can beat even the Rammus by a professional use of your ulti and help of your team to help you get back your ulti. Items are Mobility Boots > Health Potion (this is good if it happens that you take dmg) > Priscilla's Blessing (the best capture-only item because of capture rate and movement buff) > Catalyst the Protector (fast levels making it OP on Dominion) > Shurelya's Battlesong (movement speed boost along with nice survivability, regeneration and CDR) > Guardian Angel (survivability and EPIC passive that makes you not die) > Odyn's Veil (survivability, MR, mana and some damage burst for low dmg champ... if needed because the game ends now or even earlier) > Aegis of the Legion (surviveability along with nice aura if the game takes so long that there are teamfights).
That's bassicaly it. Thats how we DOMINATE.
And remember:
CAPTURES > DEATHS > KILLS > RELICS
