This is my first Guide, so please be considerate of the comments :D
I played Xin Zhao a lot of times and I think this is a really good possibility to be a perfect Xin Zhao.
So check out my Guide and please comment it :D

Cons:
-you die quickly at the beginning
-you are dependent of the money

Pros:
-you are a awesome ganker
-later in the game keeps you on no one
-you kill everybody! :D

Best Summoner Spells: Ghost and Exhaust

Ghost:
I think Ghost is the best summoner spell for Xin Zhao, cause you are fast at your opponent and they can quickly run behind
Exhaust:
Exhaust is awesome for Xin Zhao, cause nobody can escape from you :D

Other Possibilities: Teleport, Flash, Cleanse, Ignite

Very bad Summoner Spells for Xin: Rally, Clarity, Fortify, Revive, Smite, Heal, Clairvoyance

Xin Zhao need a lot of attack speed so i take for the beginning to have a little bit attack speed.
the other items are normally with xin like or something.
Shadow Dancer and Black Creaver are the most important items for Xin Zhao so i take it as the first items.
is also a important item for Xin Zhao to do the damage what you need.
The last item is because it is one of the best items for the late game.

Mark:
I take 9 Greater Mark of Desolation because its important to do a lot of damage from the beginning.
Seal:
I take 9 Greater Seal of Attack Speed because it gives you a lot of attack speed which is one of the most important things that Xin Zhao needs.
Glyph:
I take 9 Greater Glyph of Cooldown Reduction because with this runes you can use your abilities much more.
Quintessence:
I take 3 Greater Quintessence of Desolation because it gives you much more Armor penetration than normally.

Xin Zhaos Skills are awesome ganker skills. With this Skills nobody can escape from you :D


Your passive heals you every 3 hits. This is a HUGE advantage in early game. It means you can lane for long periods of time without wasting money on lifesteal. Even mid and late game you will be healing rather quickly with all the attack speed you will be getting. Keep in mind that if you want to keep laning but are scared of the enemy, jungling for a bit is a viable option to get your health back up.



This is the skill you will level up first, and it will be your bread and butter throughout the game. Not only do you get in 3 quick hits with bonus damage, but you knock up your opponent on the third hit. This allows your teammates to help you out, or slows down the enemy enough to get that kill shot in. Spam this skill as much as you can. It works great in combo with the active of Battle Cry, because your 3 hits will get in faster and the cooldown on TTS will be extremely short.



This skill is great in itself as a passive ability. It boosts your attack speed up to 35%. That's like two daggers for free! You'll want to level this skill early because attack speed benefits Xin like no other champion. Faster attack speed with Tireless Warrior means faster healing. It makes your Three Talon knockup hit sooner. It makes your cooldowns reduce more quickly with Battle Cry's active. Moral of the story? You want attack speed.

Battle Cry's active is also amazing. It doubles the bonus of the passive for 7 seconds. An extra 70% attack speed? Yes, please! Also, during those 7 seconds all cooldowns are reduced by 1 second. This is a HUGE benefit for three talon strike. Don't forget, this also reduces the cooldown of your ult, making it nearly spammable. Word of caution: your passive attack speed bonus goes away while this active is on cooldown. That shouldn't stop you from spamming this skill (extremely low mana cost) to farm and get your ult off of cooldown.



This is a great skill for initiating fights. It's a distance closer, but also slows all enemies around the target. Typically after using this skill, you want to immediately use your ultimate for maximum damage. One point in this skill early is useful for closing distance, but we're going to hold off on more points till late game. The increased slowing is really nice, but we already have many tools for slowing the enemy, as well as a high movement speed to chase the baddies down.



This great skill deals some flat damage, as well as a nice 20% of the current enemies health. What does that mean for you, almighty enemy pwner? Use this skill first when you are going for a kill, while their health is still high. A typical skill sequence is Battle Cry, Audacious Charge, Crescent Sweep, Three Talon Strike, and repeat the TTS and AC as much as possible. Not even tanks will last very long.

The items on any champion are very important... But Xin Zhao in particular really benefits from getting the items in the order listed below.

The ending Item Build looks like that:
