Ok so this is my first guide feel free to critic and give comments. To be honest i got this build from playing her once so it isnt probly the best way to build her but i will give explination on all this later in the guide.

Marks: Marks are Flat armour pen.

THis is standered for pretty much every ad champ out there so i dont see why i would put anything else on her.

Seals: Flat Armour

To be honest she is a little squishy at the beggining of the game so thats why i picked these. Plus if i remeber correctly its fairly standered for a bruisier.

GLyphs: Flat MR

Same reason as above

Quints: FLat Hp

Again the same reason as above.

TO be honest it just adds a little bit of defence and the basic offencive masteries. I will probly get yelled at for these.

Start: Dorans Blade. Fairly normal, gives life steal, HP, and DMG. Maybe swap it for a dorans shield or boots and hp pots. Just buy what you think you will need.

Boots: Merc Treads. I belive these are a must on allmost all champs. So buy them and dont complain about it.

Core:
1. Bloodthirster. It gives good damage and life steal and is fairly op.

2. Aegis of Legion. Adds HP, MR, Armour, and DMG. You need all this so why not get it all from one item.

3. Last Wisper. Gives nive DMG and Armour Pen. Yet again a nice Item get it.

Super LAte game:

THese are all situational so its basicly get what you need here. The items in the item list are all what i would look into. But, you could allso look into a GA, or an IE, or a Black CLeaver. It all just really depends on how the game is going and what you team needs.

I stole this from another build. cant remember who, i will give credit if i find it. but its a nice skill order and i like it.

um probly Flash, Exaust. They are the two most broken summoner spells in the game so i dont see why not using them.

You could allso use ignite if your team needs one, or maybe telly, but i personly would stick with Flash, and Exaust

Ill add more as i play her more and get incite from you guys.
