Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Show me Your Critz
Ok so for the boots, you should get the Cooldown boots. It wasn't listed on there so i just left it as a reg pair of boots. So the full item build goes:
CD Boots--Rageblade--Infinity Edge--Hexteck Gunblade--Phantom Dancer--Nashors Tooth.
At this point your Critz will be hitting around 900+ and with the attack speed and lifesteel it makes it almost impossible to kill you when you can heal and make yourself go invulnerable. I just recently put this build together, i would have had a pentakill but it was stolen so i only got the quad kill.
Pros / Cons
Pros: You can attack at a great speed and kill a tank in about 5 hits or a squishy in 2 or 3.
Cons: Haven't found any yet, maybe the fact that you don't consistantly slow but with the CD it should be fine casting your Q spell. Or you can get a redbuff.
