Very good AP item, but I never see it in guides. I like to build it when I gain a good advantage to help to snowball outta control. Have been very impressed with it, what is the general consensus on it's power level?
5 stacks makes it cost-efficient. If you can keep it at 5+ stacks for a majority of the game it's a great item, especially if you can get it to max. If you aren't winning hard early then it's better to just skip it.
Basically it's a high risk/high reward item. Leblanc's use it a lot.
Who needs logic when you can just speak loudly?~cookie_kid LoL IGN: I Rock Ths
