User blog comment:Kait-zero/Olaf: First item to build?/@comment-65.128.197.238-20120519194728

Imo, Boots, Phage and Zekes should be your first 3 items.

Then upgrade phate to FM and buy an atmas and you're golden for mid game.

Finish with a Maw and either a bloodthirster/GA and you're endgame is complete.
