Something that is actually great about him is his passive multiplying with a warmogs.
He gains like 30/30 from passive at 10 seconds so getting a warmogs as your 1 survival item gets scaled with the passive. His passive with a warmogs makes those irelia dives a lot less painful and makes that irelia go ???? after they realize they didnt kill you from the intital GCD.
Graves passive, someone has bulwark, graves has a warmog as his survival item. You have an adc that has like 120 armor/100 mr and 1k health from warmogs. Graves sits just over 3k health usually.
I've had great success doing BT rush/atk speed boots/phantom dancer/warmogs/IE/LW
Usually at least get the giants belt after phantom dancer then go IE/LW, if you are worried about the dives just get the warmogs after dancer.
And yea i know warmogs blah blah warmogs, but his passive makes that 1k health more like 1200+ health. --- I don't always lose, but when I do it's purple sideu!!!
