Hi im Rocky0711 this is my first build and it worked out pretty nice for me so I hope the best for all of you that love Graves as much as me. :)

Now in the game I dont have many runes as I am reletively new to it and I am focising on champions so please dont rage. I take these runes as Graves is a ranged DPS carry as you know so attack damage and attack speed are important and I played with this build without runes and had %100 crit chance dealing 1200 or more a second with basic attacks.

Now I take my 21 attack masteries for the same reason I would take my runes... FOR KILLING as these masteries and extremely effective for Graves feel free to make changes to what suits you.

My main skill would be buckshot as of the wide range and good damage rellying on physical damage. I use smoke screen for that extra damage on the minions of to annoy the enemy champion inabiling them from seeing me. Quick Dash i use for catching up to someone for that last critical hit lategame or buckshot and for escaping or taking down turrets.

I take the dagger first for the attack speed to build into berserker greaves. then i build a Phantom Dancer to get more attack speed and speed mostly (the critical chance is nice to). Then I build two infinity edge's for alot more damage and critical hit chance and more damage with critical hits with the passive enabling critical hits to deal %250 damage instead of the %200 originaly. I then bought cloak and dagger to push my crit chance to %100 and I was a major damage dealer after that. I finish with a Starks fevor for more attack speed and lifesteal.

I take teleport so if i get ganked and die or escape on low health i can be in the fight as soon as i am at full health. I use clarity because i hate having no mana to finish someone off.

I hope this works for you please vote and comment for any suggestions and u hope you can get the full build before they get tired of you owning them ;)
