Hello i am BlueSu1989 Ez was my first 6300IP champ and i am playing from BETA so i know what i am saying. Some of patches nerf him a lot as a AP so i would not reccoment you going this way. I will make it short. Just check it and add Comments and sugestions thanks.

What you need is runes for Armor Penetration = more dmg deal, mana regen/resist more Q or less dmg from casters, cooldown reduction more Q,


GREATER MARK OF DESOLATION

GREATER SEAL OF WARDING or REPLENISHMENT

GREATER GLYPH OF FOCUS

Quints as you wish in A.Pen Q.red or whatever you think you need for your gamestyle.

Like on scheme typical AD 7 points in def for more survi it save me often with 20-30 hp in teamfights and i am still dangerous with this ammount of health cuz i can lifesteal creeps and came back to deal more dmg. 1 in Utility for flash CD usefull if you are using Exhaust put in where you preffer.

Doran Blade
Boots, + Dagger = Berserker's Graves
Ruby Crystal + Dagger = Phage
Brawler's Gloves + Dager = Zeal
Vampiric Scepter (we need some sustein)
Amplyfire Tome + Sapphire Crystal = Sheen

Trinity Force = You are killing machine

Then Blood Thirster --> Bloodrazor Madreds --> PD or IE or BC depends from prefferences of player.

If you need survi then try Frozen Malez, Warmogs, Atma but i preffer non survi dmg concentrated build.

R>Q>E>W

Easy enough ?

There are only few options. I reccomend Flash, Ignite. YES we have blink but its have long CD. YES we have runes but still its too long. Flash usefull in underturret kill and run actions. Ignite for Mundo end else healing annoying targets.

Exhaus ye if you have problems with defeating others AD but you should have not.

PROS
+Fast
+Nice dmg Burst
+Long range
+Good escape ability and chasing ability
+Sniper ULT just need to master it
+Hes Awsome
+Passive attackspeed buff usefull in team fights when you will long Q auto attack Q auto attack.

Cons
-Papermade
-long cd for E
-Hard to master
-you really need to kill in early game

Easy last hit with Q if you have problems with auto attack.
With passive you can clear wave fast.

Use ult to help you friend in 3v2 or 3v3 far from you fights. Use it often in the beggining of team fight to let em know they need to run then just E+Q Auto Attack em to death.

Stay back and kill all dps who will attack your buddies.

You need gold yep ?
See that creeps weave over there ? Bot turret gonna fall.

Heyah ! ULT Boom Cash in pocket turret save and you doesn't have to go anywhere.

Try this build masteries runes if you don't like it. Do not use it again. It's for players with high EZ skill who knows how to stay alive and deal dmg from safe distance.

You will have hight att speed some crits and lifesteal you have all what you need for LEGENDARY!

Go to summoners rift and show them whos the BOSS. They belong to the museum !
