Introduction

This is a build that takes advantage of Cho'Gath's Vorpal Spikes ability, as well as powering up his other AP abilities. The idea behind it is that Vorpal Spikes is only limited by attack speed, not mana or cooldowns. So when you combine AP and attack speed bonuses, you basically become a Melee AD carry, only running off of AP. This allows Cho to use his mana for Rupture, Feral Scream, and Feast, and to be in permanent range for using Feast.

Pros and Cons

Cheap Build

Cons

Squishy
Low Max Mana

Skill Sequence

Obviously max Vorpal Spikes as fast as possible, then Feast. Rupture is really good for opening up your enemies for melee attacks, so max that next. Lastly, finish off Feral Scream. With this order, you will be able to do tremendous damage with the Vorpal Spikes and Rupture combo.

Item Build

Start with a Doran's for survivability and the quick AP. The mana regen won't be too needed, but may be required since Rupture can be very expensive. After that, get Beserker's Greaves. Here you will start to notice how effective Vorpal Spikes can be. Follow that up with a Giant's belt or Blasting Wand for Rylai's Crystal Scepter, which will slow down your enemies when using any ability, but more importantly, on Vorpal Spikes. This will make you quite beefy at this point, considering your Feast stacks as well. The last 3 items will increase you ability power and attack speed, but effectively in different ways. Malady will shred MR on you enemies when you melee attack them, leaving them more prone to damage from vorpal spikes. Next, you can get Nashor's Tooth or Wit's End in any order. I prefer Wit's end because of the magic resistance, but if the enemy team lacks AP characters, go for Nashor's. After this, you can hit 2 times a second, which is 6 to 8 attacks when you land Rupture. When you can do 200 damage or more with 1 attack, along with Rupture and a Feral Scream, you have one dead enemy.

How to Play AP/Attack Speed Cho' Gath

Laning

AP/AS Cho'Gath can be extremely powerful. When laning, just having Vorpal Spikes out makes you incredibly annoying to all melee and short ranged champions. Your spikes will hit and minions and enemies in a line, so you can harass and farm at the same time, all at no cost! Take advantage of this as much as possible. When your enemies are at half health or so (or even full if you have Feast), place a Rupture underneath them, use Feral Scream to ensure they don't stun you or dash away, then attack with your auto-attack. It's that simple! If laning with another person with a slow or stun, try to coordinate with them in order to provide the maximum amount of slowed or stunned time you have with the enemy. This will ensure a gank in almost all cases.

Jungling

Just like Lane Cho, grab vorpal spikes. For items, buy cloth armor (or a dagger preferably). Continue with the build just as you would. If you do get cloth armor, you can build that into Guardian's Angel, which will be useful later for survivability. Start at blue, and eventually try to fill your stacks from the Red and Blue buff monsters, or dragon.

Team Battles

In team battles, you will most likely be focused due to your size and proximity to the enemy champions. That means you need a good tank, and need to know the perfect moment to strike. When an ally has initiated, throw Rupture at the carries and begin to attack them. If they happen to be AP carries, make sure to use Feral Scream early. Because Vorpal Spikes can go through multiple enemies, you can be incredibly effective in close-quarters team battles.

If you can, GET FULL FEAST STACKS
