Passive: - Xin Zhao restores 30 health for every 3 attacks that he lands. This amount increases by 5 every 2 levels.

Very useful when staying in lane, because of the healing you can stay in lane much longer.

- Xin Zhao's next 3 standard attacks deal increased damage, with the third attack knocking an opponent into the air.
Xin Zhao prepares to unleash a fearsome combo, causing his next 3 standard attacks to deal 15/30/45/60/75 (+) physical damage, with the final attack knocking his opponent into the air.

This skill is really powerful, not only because of the huge bonus damage but also because your 3rd attack will give the opponent a Knocked Airborne status (in which you can easely finish him of or stop him from running).

- Xin Zhao passively increases his attack speed and can activate this ability to further increase attack speed and lower his ability cooldowns with each attack.
Passive: Increases Xin Zhao's attack speed by 15/20/25/30/35%.

Active: Xin Zhao unleashes a battle cry, increasing his attack speed by double the passive amount for 7 seconds, and causing his standard attacks to reduce all other ability cooldowns by 1 second.

Activating this ability removes the passive bonus until this ability refreshes.

I really love this skill, mostly because of the passive attackspeed bonus, but the active is also really useful when ganking.

- Xin Zhao charges an enemy, dealing damage and slowing it and all other enemies in the area.
Xin Zhao charges an enemy unit, dealing 70/110/150/190/230 (+0.4) magic damage to all nearby enemies and slowing them by 20/25/30/35/40% for 1.7 seconds.

This is your primary ganking/chasing skill, it deals quite a lot of damage and it slows the opponent for a significant amount for a short duration. The slow's duration is enough to use your [ -> -> -> combo.

- Xin Zhao fiercely sweeps his spear around him, dealing damage to nearby enemies based on their current health.
Xin Zhao unleashes a fierce spear sweep on targets around him, dealing 125/225/325 + 20/20/20% of their current health in physical damage. His magic resistance and armor are increased by 30/40/50 for the next 8 seconds.

Just a great damage skill, even against tanks.Note: Crescent sweep deals damage to all enemy unit AROUND Xin Zhao, so it is useful in teamfights.

I start off with Dagger (in order to get your passive faster) and a health potion. I try to get as soon as possible (they are useful because of the 35% crowd-control-effect reduction).

Greater Mark of DesolationGreater Mark of Desolation: +1.66 armor penetration
Greater Seal of Strength: +0.43 attack damage
Greater Glyph of Strength: +0.28 attack damage
Greater Quintessence of DesolationGreater Quintessence of Desolation: +3.33 armor penetration

These runes are mostly based on giving you a greater damage output.
It might look like not much, but it can give you just that little more damage that is needed to kill someone.

I start off with Dagger (in order to get your passive faster) and a health potion. I try to buy the ( Mercury's Treads: +25 Magic Resist UNIQUE Passive: Enhanced Movement 2 Reduces the duration of stuns, slows, taunts, fears, snares, sleeps, and immobilizes by 35%.) as soon as possible, mostly because of the passive (which is really useful when Towerdiving).
Next up is (The Black Cleaver
+55 Attack Damage +30% Attack Speed UNIQUE Passive: Physical attacks reduce your target's Armor by 15 for 5 seconds (maximum 3 stacks).) because of the damage/attackspeed/passive this item just TOTALLY fits in this build.

After that i buy the (Infinity Edge: +75 Attack Damage +20% Critical Strike UNIQUE Passive: Critical hits now deal 250% damage instead of 200%.)

The Infinity Edge's damage and crit strike provinde great damage output, and it's passive gives you EVEN MORE damage!

Then i buy 2 (Phantom Dancer: +55% Attack Speed +30% Critical Strike +15% Movement Speed) because they not only give awesome attackspeed and critical strike chance, but also a great movementspeed bonus (which is really useful when chasing).

And last but not least: (The Bloodthirster: +60 Attack Damage +15% Lifesteal Passive: Gain an additional 1 Physical Damage and 0.25% Lifesteal per kill. Maximum of +40 Damage and 10% Lifesteal. Bonuses are lost upon death.)

Just look at the item, the damage/lifesteal and passive make it deadly in combination with the other items. (Just make sure to farm A LOT of minions)

Early Game

In the beginning focus on minion kills.
