Cho'Gath's utility comes from AOE and CC skills; Rupture, Feral Scream, and Vorpal Spikes all serve those purposes.
Use Feast to last hit large monsters and enemy champions to gain Feast stacks and gain bonus health.
League of Legends Cho'Gath players may find him to be a complex champion to build out properly. You will see that his build changes when he is up against either well-rounded or homogenous team comps, indicating you shouldn't take the same Cho'Gath build every single round of League of Legends
The best items to incorporate into your champion's build include: Heartsteel, Gargoyle Stoneplate, and Abyssal Mask. Those who added these items in their setups had a greater win rate than those who tried for other Cho'Gath builds. Similarly, if you are playing a well-mixed enemy team composition, you should really consider grabbing yourself the Resolve, and Precision runes. In recent games, he won the largest fraction of his games when built with these runes.
We came up with our Cho'Gath build guidance by examining 42,803 recently ranked League of Legends rounds with him in them. We only propose the highest winrate Cho'Gath builds that were built by ranked League players enough times for us to propose them. With so many games in our dataset, we are confident in our provided builds.
