this is my first guide. Always graves should have huge attack and critical damage. the Bloodthirster gives Graves lot of attack damage and life steal which specially in early game should use on minions,so the Bloodthirster is important in early game.Phantom Dancer is usefull next if u want kills on 1 vs 1.Infinity edge gives again lot of attack damage and critical damage.Now you should do lot of damage and use your life steal on blue buff, red buff, dragon and enemys.Last whisper gives you valuable armor penetration.the Black Cleaver gives you final shot to full build.Elixirs may not be smart but if u have Twitch or Teemo at your game in enemy side you should buy atleast Oracles Elixir.I have used my build a and it gives me lot of edge in early game.In late game if you have full its usually quite a tied in damage.This build gives you huge edge in 1 vs 1.Build is bilt by Nolotus.






This build gives you

:lot of attack damage and critical damage

:edge in 1 vs 1

MORE

If this build is bad then don't use it.
Still this is my first guide so there is not so much information.
