Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
This is my build for Cho'Gath. I go straight up tank because that's what he is. If you feast and stay alive, getting Leviathan stacks, I usually have around 6000+ health. You dont need any more than the +80 AP of ROA and I have too much health and armor to die so I usually win 1v1 or team fights. The weakness is getting ganked. Ganking you have no speed to run and if youre teammates arent fast enough, you can die. THIS BUILD IS NOT INVINCIBLE. (even tho youre running atleast 5500+ health.) I use Flash and Exhaust because Flash is a must spell and Exhaust you use if theyre trying to run away or if they are chasing you. Runes, Masteries, they explain themselves. Items, you dont really hafta buy them in this order, its just what works for me, but they can be mixed around but i would stick with getting Guardian Angel early so you can have that advantage. So, yeah, Rate, Comment, Advice if any. Enjoy. :D
