Cho is a very unique tank. he's not just a meat shield, (while he's one of the best) he can also provide great support and even save lives when his rupture and feral scream are used properly.

I play cho as a support tank, especially early on. i know i may get some criticism for buying dorans ring. but trust me, the mana regen will help you lane longer; harass more. the 15 ap will help you get that extra umph in damage to harass and even kill enemies in your lane, and the 100 health is icing on the cake.

This build is obviously subject to change based on the enemy team composition. more AD? glacial shroud before negatron cloak. more AP? visa versa. same goes for frozen heart and force of nature. if you're looking to go more of a tanky mage cho, then swap frozen heart for rod of ages. i personally enjoy the CD reduction and the slow down on enemy attacks, and it makes Cho, and his surrounding allies, much tougher to kill.

I LOVE Leviathan on Cho. once you become confident with him, it can make you unkillable. especially if you reach 20 stacks. coupled with 6 feast stacks? maybe even a warmogs?? you get the picture. Feast early when you can. i prefer to kill either the larger minions, a golem, or the large wraith to also get more gold. speaking of gold, cho is a great farmer, in my opinion. one rupture and a couple of strikes with vorpal spikes can easily give you a couple hundred gold on a decent sized minion wave.

summoner abilities for me, i almost always go flash and cleanse. i see a lot of use of clarity on Cho. but i believe that if you blow all of your mana while laning early on, you're either not doing a very good job, being careless, or not cooperating with your lane partner. if the opportunity isnt there or doesnt look good, dont take it. ghost can be substitued for flash, but i enjoy the flexibilty of flash. cleanse is more for early laning if you are getting harrassed and say eve comes in and stuns you. coupled with flash, cleanse will give you a great freebie chance to avoid an incoming gank.

a good laning partner is a great key to success. lane with a good blitz whenever you can. his rocket grab, coupled with his charged punch is deadly enough. throw in a rupture on the area the enemy gets pulled to and a feral scream, you're pretty much guaranteed a kill. don't underestimate the power of teamwork! :P

i'll end this build on a few notes.

1. i will rarely ever have to buy warmogs.
if you can get enough stacks on leviathan and your team is pretty good, the game will usually end before you even have time you buy it. if you're facing a pretty tough team and have died a couple of times early on, or your team is struggling, swap out leviathan for warmogs. NOTE: it is much more expensive and will set back the rest of your build, only buy the giants belt until you know you need warmogs

2. DONT FORGET ABOUT FEAST WHEN FIGHTING ENEMY CHAMPIONS!
a lot of people forget about feast. it deals true damage based on what level it is up to (+50% of your AP). just check how much damage you do with it at the moment, and as soon as an enemy drops below that point, feast them if you are close enough to do so. dont be shy to do it with a few team mates around even if they have a little more health than you want to finish them. it's a team based game after all. :P easy kill, free gold, not to mention it's pretty tasty :)

Hope you all enjoy my build!
