Hi everyone, and welcome to my first guide here on mobafire! Xin Zhao is one of my favorite characters. I first tried him out when he was free, and it was victory at first game. And second. And third... so I decided that I was definitely doing something right. After a little fiddling and tweaking, I decided to publish a guide. Hope your games will be as rewarding as mine! Enjoy...

I'm not a pro player, so if any of you think there's something I should add or change, just put it in the comment box!

Pros:
Distance closer
Knock up
Group slow
Natural heal
Unstoppable when fed

Cons:
Picked on by ranged
A bit slow without items
Vulnerable to cc
No escape mechanism (except speed)

I take a pretty typical 21/9/0 build. All that offense, since you are a carry, and a little bit a defense for some survivability. 'Nuff said. If you think I should explain some things, feel free to comment.

Your rune choice as Xin is quite limited.
For AD junglers, there are like 3 options:

Attack Speed, Attack Damage and Armor Penetration.

Attack Speed: AS speeds your early jungle up, thats it. It makes you healthier due to more passive proccs. And of course.. more Attack Speed results in faster Auto Attacks (could you have ever imagined that Oo), thus you'll clear your jungle faster.

Attack Damage: AD runes are awful for Xin. Xins abilities have no AD scaling, what makes AD runes a real waste on Xin.

Armor Penetration: Every jungler should get at least 12 ArP by runes, since the small creep camps have only 12 Armor or less. With 12 ArP Xin deals true damage to those. More affects buff-creeps and of course enemies. Best choice for Xin.

This background results in:
9x Greater Mark of Desolation
3x Greater Quintessence of Desolation
9x Greater Glyph of Celerity
9x Greater Seal of Alacrity
