Well , I'm playing League of Legends for 2 years and Xin Zhao is my favourite champion. i like this build becaususe it gives you high mobility , awesome damage output and a lot of kills. In this guide I'll teach you how to dominate almost every lane in Summoner's Rift with Xin Zhao.

Pros:
- High mobility
- High DMG
- High AS
- can save ally or himself with disables

Cons:
- If hard CCed can be killed quickly
- Haven't got much armor niether MR nor HP

The reason I'm taking these runes is that you need AD and AS to be successful assassin with Xin Zhao. They give you a lot of advantage in early game.

I think these are standard masteries for an assassin. Not too much to talk about.

Dorans blade --> useful for start ,later sell it and buy Black cleaver.
Berserker's greaves --> This gives you AS + mobility for early game
Phantom dancer --> This'll secure you high mobility trough game + AS
Vampiric scepter --> Your durability which needs to be stronger as game goeas on
Infinity edge --> Now, you need some damage so lifesteal becomes more useful
Frozen mallet --> I take this mostly because passive , but it gives you some health
Black cleaver --> People stert getting durability so you need to get more DMG + AS
The Bloodthirster --> More durability and DMG

I focus mostly on Adictious Strike , which is wierd to most of you because it deals magic DMG , but when you charge on someone Xin lands 1 basic attack + DMG from ability and thats one hell out of DMG dealt in early game.Then you need AS+durability in lane and that you can get from Battle cry.

I usually get Flash and ignite - escape and dmg
But you can get - Heal ; Ghost ; Exhaust

I'm 3000Yankee and I'm glad if you found this guide helpful. Try to play , then judge ;)
