With this build I can easily go in a fight against two people or in some cases 3 and win. It is very good as it takes a lot of critical damage every hit since is has an 100% critical chance and 250% critical damage from Infinity Edge. This allows you to take tons of damage from a single player in a matter of seconds and be able to deal with the next very quickly and efficiently. The Berseakers Greaves and the Phantom Dancers give you a lot of movement speed which is very usefull when chasing enemies or getting out of a tough situation. It sometimes outruns some of the faster players such as Master Yi. With this build you cannot fail because the auto-attack itself takes away 650+ damage, so even without mana, you can still kill your enemy, and that has happened to me a lot of times. Happy playing and please vote this build if you like it.
