This guide is for an extremely burst damage intense cho'gath who will be able to gank and survive in team battles while doing the most damage possible. FYI this is my first guide, but I have played cho'gath numerous times and will try to test this build out. It is pretty costly as rabadons, lichbane, and hextech are all in the mid 3k range. I was thinking of putting the bilge-water cutlass in after the sheen for its active (and combo with the mainly melee vorpal spike skill focus)to give better early gank potential and survive-ability. The early sheen is due to cho'gath having a relatively high starting ad, I'm not sure if vorpal spikes trigger the bonus from sheen though.
P.S. Thanks for checking out my guide and I appreciate any advice.
