Well this is my first guide here at moba (also, my first post), so bear with me if there are some inconsistencies with the guide and such.

Ok so, here's Graves, The Outlaw, he's a cowboy, the awesome kind, not the ones that keep secrets on brokeback mountain or something, he's a ranged AD carry that encourages you to go to the frontlinesm, he has an awesome VA and, come on, look at that shotgun, isn't He awesome?

Pros

Awesome Voice Over
Nice Damage Output
Has a dash that can save you from sticky situations and can go through thin walls
Nice Passive
Mini Nocturne's ulti on W
Q/R combo can be devastating

Cons

Mana hungry early game
Since you have to go to the frontlines, you put yourself in danger
Itemization is costly

For runes I take Armor pen reds, Flat Dmg quints for early game power, Flat armor yellows that synergize well with Grave's passive and Mana regen blues for that early game hungryness.

For masteries, i go with 21/0/9, armor pen is always nice, critical chance and exp for utility tree.

First Start off with a Doran's Blade, then on my second trip back, i go for another ]Doran's Blade, if you're getting harrased badly and denied, you can go for a third Doran's Blade after you buy some Boots, if not, upgrade to Berserker's Graves as fast as you can, then start building Phage, to get those pesky cowardly champions that try to get away, after that, build Sheen, since the proc makes so much damage after buffing your attack speed with Quickdraw, then, start building your Bloodthirster starting with the B.F. Sword Best Friends sword if you're doing well, if not, buy the Vampiric Scepter.

After that you can start selling your Doran's Blade to complete the Trinity Force, and then move along with the Infinity Edge, and finally, you can buy another Bloodthirster if you're doing okay, or a Black Cleaver or Last Whisper if the enemy is stacking armor.

You should get a point on Buckshot on level 1, then a point on Quick Draw on level 2, Smoke Screen at level 3, then start maxing Buckshot right away, after that, max Quickdraw, then finally Smoke Screen, the Ulti must be leveled whenever there's a chance.

For Summoner Spells I take Exhaust and Flash, this Setup is perfect for closing gaps and start melting the enemie's Health bar.

Well, that's it for now, corrections and correct formatting will be made when i have a chance, Comments, corrections and sugestions are welcome, insults are not :D
