When you go on the lane it would be best if you went with a stunner so it becomes easier for you to get many kills which gives you better ganking possibilities on other lanes after you take the turret. When you are about to gank start your three talon strike on creeps and on the last hit charge to the opponet and strike him uppward, after that let your stunne stun him and activate your Battle charge so the cool down on the Three Talon Strike and Audacious Charge so you can hit them up again.

Don't use the ultimate to last hit the champions, you should use it when they have about 50% HP to get the best damage. Gank alot that's what Xin Zhao is best at and the team realy appreciate it.

In late game you are pretty tanky, so you should jump in first and use your ultimate immediately so you get the magic resist and armor buff, and make their team focus you so your team can go in and go all out on them.

I pick Three Talon Strike on level 1 in case we can get a kill in the bush on the lane, and I specc on Audacious Charge so i can charge togheter with Three Talon Strike with the stunner and take as many kills as possible on that level so their farm gets destroyed and you can start ganking as fast as possible.

I use ignite to use in early game if they get away with low HP so I can secure the kill.

I pick exhaust so I can use it when i run into a bush with low hp, then I turn around and activate all my spells and use exhaust on them so i can get a kill thanks to the passive and exhaust.
