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.
No sheen? No lich bane?
You sacrifice that for bieng half tank, and chances are you are still highly able to score solo kills. This build sounds crazy but I EMPLORE you to try it.
Rush Catalyst perhaps even before boots, and use it to become tough (both in mana barrier and actual health) as well as able to lane for extended periods of time. Rod of ages adds to this, you gain strength and become a tank in both hp and mp. Boots come next but you should already be a force to be feared 1v1 or a great support. Crystal sceper is for two reasons, on top extra health while giving hp its slow affect helps you to be a great support OR 1v1 champion a your lightning will strick periodicaly making you nearly impossible to escape from. Cyrtsal heart makes you more of a support tank, as well as cooldown reduction for 1v1 instances. You are sturdy at this point, go for zonas ring to up your power even further while at the same time giving you ANOTHER defencive mechanism.
Generaly the game is over by zhonya, but if it dosent garudain angel completes your transformation.
Ghost+overdrive makes you impossibly hard to shake off or chase the whole game.
Crystal scepter+ fatiuge alows you to hunt 1v1 or set up kills for your team with a crazy success ratio.
My blitz is designed to be able to therefore, hold itself in whatever situation it is put in. I have yet to see another build that can handle opponents in a team fight AND 1v1.
