At the beginning you should skill AUDACIOUS CHARGE [E] if you go for first blood. But you have be fast and do it with your premades. You probaly get the first blood. After the kill or kills you go up.

Farm always, when the enemy is in range activate Three Talon Strike, Battle Cry attack him with Audacious Charge and try to kill him. You get mostly very fast feeded. Jungling isn't very usefull with Xin so just keep farming and when an enemy come near just activate Three Talon Strike, Battle Cry, attack the enemy with Audacious Charge and then use your ulti. Try always to gank if possible.

At the end you probably already have the first 4 items. If not stay deffensive and farm. If so you can probably beat everyone in 1v1, mabye even 1v3. Just stay with your team and push. You have the best chances to push, when you compet in a team fight and 1-3 enemy's. And at the game when you say ''GG'' when youve won^^
