Before I say anything else, I'd like to make clear that it's not always going to work. You'll have to adapt your build according to the enemy team. But if they're a team which considers of mostly low HP champs, then it can make miracles.

Why these items?


You're playing a champ with AD, who can reach up to 6k HP with just 10 stacks (and the items ofcourse). Goredrinker is giving you the best (personal opinion) stats you'll need with this build. It gives you 45 AD,40 Ability Haste at full build and 400 HP to boost your item strength and your ultimate.
But the most important thing is that it gives you a tone of heal in fight, because when you'll reach 3 or 4k of HP, then, with a single use, you'll have the chance to refill a good amount of your missing health (we're talking about 25% AD, which scales with your HP since you'll probably build Titanic Hydra + 8% of your missing health. And it's the missing health of the champ who has no limits to it).


Then we have this bad boy. It's the main source of your AD. It gives you 30 AD and 500 HP and a good cleaving attack. But the main thing it does, is that it gives you 1% extra dmg according to your HP. At 3k HP, you'll earn an extra 30 AD, but you'll probably reach more, because hey, you don't even need to try to reach 3k HP with this guy. And another bonus is that the cleaving attack, is nicely combined with his Vorpal Spikes.


Last but not least, we have the Gargoyle Stoneplate. I believe that this item, at late game, is probably the best thing you can have with Cho'Gath and this build. It gives a shield equal to 100% of your bonus health. That's enormous considering you'll have at least 10 stacks and full build. Plus, it can give you a chance to use the Goredrinker one more time.

That's all I have to say about the items. The only thing I feel like I need to add is that, in case you're building against AP team, then this item should be in your item pack Maw of Malmortius. Because the Magic Shield that it gives you, is equal to 20% of your MAX health. And it gives you some bonus damage too. So it's a perfect stack for AD Cho'Gath.

Now about the runes.
You can go with anything you want with this build. But the reason why I chose these is because whatever gives extra health to Cho'Gath is good, but whatever gives him heal depending on his HP is even better.
And the runes I've chosen are perfect for this (or at least that's what I think :D)
I don't really have to say anything about the reasons why I picked these. These few things I've said explains it all.

My nickname is Ðoc Morning Wood. I'm a silver EUNE player and I created this for fun.
I have no dreams of becoming a better player and, to be honest, I don't really want to.
I hope you enjoy your time trying this build and please don't hate if you don't succeed much with it. Like I said earlier, It's for fun!
Thanks for giving it a chance though (if you did).
Have a nice day and good luck with the rest of your games. :D

Got nothing more to say. See you in the game!
