Bruiser Xin Zhao Build

General

1. Enemy team heavy on AP? Buy MR. Are they heavy on AD? Buy Armor. You need some damage? Well buy that.

Champion

1. Always keep auto attacking - this gives you great sustain, especially early on.
2. Always count your Three Talon Strike (Q) attacks. You can attack minions twice, then Audacious Charge (E) (combined with Flash) and knock unsuspecting enemies up!
3. Combo #1: You can cast Wind Becomes Lightning (W) and Flash. It works forward/backward and sideways. This lets you get some cool kills.
4. Combo #2: You can cast Wind Becomes Lightning (W), Flash then use Audacious Charge (E) to reach. That's a super cool combo that lets you catch people off guard and engage from miles away.
5. Combo #3: You can cast Crescent Guard (R), then Flash. This way you do some surprise damage, or even throw enemies into your team if used properly (keep track of who is Challenged!)
6. Combo #4: Prepare your Three Talon Strike (Q) to have knock up ready, then you can Flash into an enemy team, use Crescent Guard (R) to knock everyone back and immediately knock your target up to keep him in place. You can follow up with Audacious Charge (E) and Flash if needed.
7. Combo #5: You can Audacious Charge (E) to a minion + Wind Becomes Lightning (W) during dash animation for surprise hits. This is especially cool, when your build revolves around W (Lethality, Crit, AP builds)

Riot

1. Xin Zhao is a great initiator to combat. Lead the front to start a fight and use your ultimate to do the most damage possible.
2. Try to position yourself so your ultimate's knockback is most effective.
