the summoner spells u want to get in risky games are... smite, flash, ghost can also be ok for the first gank but generally i would use smite and then flash or teleport if i feel i can risk it, the problem with teleport is you risk feeding without having teleport.

this item set i use is very risky but it is what i prefer. the first thing you want to do is get blue, after depending on if it was smiteless or not, you either get red or you take wolves/ghasts/golems out useing most of the pots, as soon as either of these conditions are done go back and make a madreds razor. if your top laner is struggling at this point, help them gank but the main idea from here is to get your first vamp sceptre. as soon as you hit 800g and you can risk going back, press b and get the sceptre then go for blue/red buff together. if your top laner can manage, just keep going wolves/ghasts/golems till you reach 800g smiting as soon as the cooldown is off for the extra gold from masterys. once you have both buffs, normally go for a few kills. xin at this stage should be able to solo dragon at least by lv 8 with smite, so once hes ready press b and buy the next items, and then go to the dragon. often by this point if the enemy cant keep up, gank wherever you can and try to go for the kills, a lifesteal xin can be a effective carry. with this item setup you can heal ~75% health on wolf creeps, also as xin, when you have your ravenous try to push lanes fast and use q on towers, xin at this point even can take down towers fast. the main weakness of this build is that if you are being asked to go all over the map without being able to farm, its troubling. a big weakness of xin i found to be garens silence, this can ruin a lineup as with any other kind of silence, stun doesnt seem to be as bad

normally this setup is ready so for the second trip of farming he gets his w, this is important as normally using a second level of q speeds things up early game. generally i go for r,q,e,w after w is level one from there on, a lifesteal xin is tanky enough that his w only acts as an auxillary and lifesteal xin can be just as tanky as a tank built xin

i focus on offense with xin, the extra defense masteries are generally to make starting off easier,

for quints, lifesteal helps more and almost makes a vamp sceptre, this makes farming a lot easier whilst being able to gank, i use seal of gold for a better early start on xin however you can use seal of cooldown reduction as xin is often chasing a target waiting on his e skills cd to finish. xin has enough lifesteal in this build to make it not worth getting armour, although you have to be careful at the start of the game for this. mark of attack damage is needed as my main idea in this build is to buff his early game so he doesnt get a problem in his weak spot, some will prefer attack speed for xins q to be better complemented and it makes it easier to chase people but thats preference. personally i prefer to get cooldown glyphs though u can replace that for something else for an early boon

with jungle xin zhao, he can be very effective using lifesteal, the main part he suffers though is early game, you dont want to gank early game but you will have to sometimes. you must be careful for being focused with silence, stun these are the two big things that can make you worthless. currently i havent got all the runes and stuff finished on my own char as its new, it should actually receive 80%+ from wolves when fully done up as an example of how good his lifesteal is but the main thing is that if you build lifesteal you have to carry your team in kills or its not really worth it. one big problem that i get with this build is i end up with 4k gold and find it hard to decide when to return to town after my first few ports
