Hi I'm Freefall, I just want to share you my playing style since my win rate in Xin Zhao drastically rose up. I will show you some of my pathing techniques that will lead you to your victories.

Xin Zhao is really strong and straightforward champion. You don't need to practice hard mechanics onto this champion.

If you are able to play this champion smartly. You will be able to gain free elo in no time.

This is really important to have a sure win. I highly suggest to pick Xin Zhao, if the enemy jungler is weak at early game or if the enemy jungler is a long range champion like Graves, Kindred and etc.

Pros

Strong in early game
High potential of snowballing
Can easily create ganks

Cons

Scales really bad in late game
Bad early game can put you to bad situations

BOOTS OPTIONS

Ninja Tabi is good if the enemy team composition is more on attack damage.

Mercury's Treads is good if the enemy team composition is more on ability power and crowd control.

CORE ITEMS

Black Cleaver is a must. Because it is cheap item for damage health and CDR. Good item to start with.

Trinity Force is good to take if you are snowballing. It will gives you tons of damage plus mobility.

SITUATIONAL BUILDS

Wit's end is a choice if you need attack speed plus magic resist.

Sterak's gage is option if you need damage with tankier build really ideal build for Xin Zhao but not all the time.

Dead Man's Plate is an item for mobility armor and health. Really ideal item for Xin Zhao.

Randuin's Omen is really good if the threat in the enemy team has an attack speed and critical strike builds.

Spirit Visage is a good item if you want to add more on your healing regeneration and draining effect like life steal or spell vamp. Good choice if you also need magic resist.Really good to combine with

Blade of the Ruined King is good for shredding and fighting against tank.

Sanguine Blade is good against 1v1. If you think that 1v1 against the enemy shredder is needed. Then this is a good item for that situation.

Adaptive Helm is good for subsequent magic damage like skills of

Maw of Malmortius is good if you need damage plus magic resist

Guardian Angel is good. You're 2nd life will annoy your enemy.

All Xin Zhao mains knows the level 2 gank. But my pathing is quite different. I always take the red buff. Even if I'm from red team or blue team. After I take my red, I always visit the enemy buff first before I create a gank. If I saw that the blue buff was already taken. It means the enemy jungler is either in the frog or wolves. Visit him and take advantage while he is weak.

In this video, you can see that I didn't visit the enemy's blue buff because katarina is kinda advancing her position on mid and take advantage on it. I was also thinking that maybe master yi is already in his wolves. So, I try to visit it and it is really rewarding.
