Now before we start this is my first posted build ever and I was told by a friend that he was very impressed by the build so I decided to post my build. The purpose of this build is that your ult has reduced cool down so use it when you need to like in team battles. The AP in this build makes your ult one of the best in the game because at lvl 18 you can do up to 2500 damage or more. But that's late game and lets talk about early game. In early game your Ice Blast is you lord and savior so use it to easily run from someone or to slow for a kill. Your Ice Blast will help when helping allies run from enemies. Your Blood Boil is meant to help run as well when combined with Boots of Swiftness and Ghost you get back to lane incredibly fast. Another good running tactic, use Blood Boil as much as possible when necessary, if you can use it on an Ally. Consume is great for just staying in lane because you have almost no health items. Why? Because you get so much natural health that it almost doesn't matter it is also why you have Heal. Consume alone is good for Baron or Dragon, or just minion kills. But with AP, you heal massive amounts of health through-out the game. So use it when you need it. Your ult is also perfect for farming late game because you don't have a very high cool down so use it to farm big waves of minions. Besides that use your Blood Boil and your Consume.

Now enjoy this build, rate, comment, and give constructive feedback please. And no mean comments as well. Thank You!
