this is my first build, so if i messed up somewhere, please let me know. this build rages as a high damage solo xin. with a 2.3 attacks per second, and 65% critical strike chance, your going to be doing around 1500-2500 damage of autoattack per second. jump in with your audacious charge spell, then pop you ult, and get out. if someone runs away, use exhaust and your three talon strike to pop them in the air, this will almost garanteed to finish them off.

pros

insane farmer
excelent jungler
1v1 dominate
lanes great with someone who can stun
lifesteal lets you lane forever, and jungle early.

cons

succeptable to ganks
useless stunned
ranged are not your friend

with lifesteal, you can almost immediately start to jungle. after level 12, you can even solo dragon, jungling and farming is how you gain health mid/late game. you do not need to base, but be carefull for ganks in the jungle. by this time people hate you.

exhaust-this will allow you to get those annying people who run away when you almost got them,coupled with three talon strike and audacios charge, running is not an option
ghost-you will be ganked. if you are smart and play right, being ganked by all of them with stuns is the only way you will die. the reason this is better than flash is because while active you movement speed is around 600 even ash will not be able to catch you.

if you are against melee, get battle cry first, and rack up on minion kills. then audacious charge, then three talon strike. audacious charge will be how you get initiate, and also an alternative to running away, if there are minions behind you. this is the most usefull spell. a good combo would be to go charge, ult, battle cry, three talon stike. in about 2 seconds, your target will be dead, and in a team fight, everyone will start to run, bacease you lose no health(with hextech gunblade's lifesteal 1v1 you come out with half to 3/4 health, then just jungle, and your back up to full hp again)

xin is not a tank, he is an assassin. get in, do a lot of damage, then get out. harassing with audacious charge is the primary goal, as wellvas setting up team ganks and coming to their aid. late game you will never need to base, just jungle, and you will regain all you health. farming is key, as xin has a pretty expensive build, also mid/late game you will be killing minions in one hit. just be careful, as you will get ganked and stunned, then you are helpless. just be careful, and please, call mia.
