This is in my opinion the best build for cho gath because it allows you to be a tank for the team while not feeling helpless fighting 1v1 against other champions. If you do happen to get full build you should be able to do a bit above 1000 true damage using your ult which means that a simple q,w,r can take down most carries and mid laners without a problem. I am still new to making mobafire guides so expect the quality to go up as changes are made.
