This is a build for those over aggressive players. I will talk about why I choose the items I choose as well as how I build up each. Also there can be some rather significant pros and cons.
And remember, be aggressive.

I start off with a Ruby Crystal, then I will get either the Giant's Belt or Berserker's Greaves.
Then, finish off Frozen Mallet (once you get this you will be able to chase your enemies very easily, especially after 50% when they actually start to run), followed by Spirit Visage. Next, work on Warmog's Armor for the health and the regen. Finally, get a Bloodthirster for more health regen in combat, and an Infinity Edge to crit them hard.

Pros:
very high survivability
very harassing

Cons:
Low damage early on
enemy team will gang up on you alot

Best done when grouped with someone who can stun and/or will stay with you... even past turrets. Best solution is to play with someone you know.
