Not Updated For Current Season
This is a build a made up from my own knowledge of twitch ownage... Enjoy.
1. Buy a longsword and start of with Expunge.
2. After several minion kills and a first blood head back to base and get your Sword of The Occult.
3. After you have your sword buy a dagger first then pick up your Berzerker Greaves.
4. By now you should have around 2-5 kills maybe 6 if your good. By now you should be able to buy a Vampiric Scepter to start off your Malady.
5. Depending on how much money you have you can either get a Recurve Bow or a Dagger for your sword of the Divine.
6. To start off Infinity Edge I usually save up for a B.F. Sword (depending on how much money you have and how the game is going). Then I usually buy a Pickaxe next and finish it off with a Cloak of Agility.
7. And to finish off Phantom Dancer and the last seconds of the game I get a Zeal (obviously) and buy Phantom Dancer.
If you build my build correctly and the game has gone in your favour then you should be ownage.
