Xin Zhao starts off kinda weak, if you dont know how to use him right. purchase Boots of Speed and 3 health potions. if your health gets too low on the battlefield, use a pot. Xin Zhao is a poker, assassin, and a troll. go for the squishy ones first, if you can. the minute you get 1000 gold, recall and purchase the berserker's Greaves and the Enchantment - Alacrity. if you got enough gold (Over 1000), purchase the Vampiric Scepter and head off to your lane again. build up the Ravenous Hydra ASAP! this will help with minion kills, trust me. then start to work on the Bloodthirster.

By now you should have a Ravenous Hydra, a Vampiric Scepter, Berserkers Greaves PLUS enchantment Alacrity. if your already OP, you probably got the bloodthirster in place of the Scepter. keep trolling people and rack up the money. if your having trouble, get to work on the second bloodthirster. if your uber-stronk already, get to work on the two Phantom Dancers. this increases your crit chance plus movement and attack speed.

By this point you should have Berserkers greaves plus Alacrity, Ravenous Hydra, The Bloodthirster, a Phantom Dancer and the starts of the second Phantom Dancer. Teamwork here is essential! follow your team around and kill people as you see fit. if theres a loner, take a friend and kill the idiot. Get your second Phantom Dancer, then get to work on the second Bloodthirster. these bloodthirsters combined with the ravenous hydra will give you 50% lifesteal, and trust me, thats a lot with your damage meter by this point. get the bloodthirster stacks quick, and the build is done. it wont matter how tanky the enemy is, you can solo any one of them with this. lead your team to kill their nexus.
