Pros / Cons

Main rune set

Greater Mark of Insight Cho'Gath's original purpose was, obviously, not meant to be an AP carry, this means we have to work around his weaknesses, one of them being the fact that he has very little magic penetration. These are helpful all the way up to level 18, as any AP carry will always need magic penetration. Greater Seal of Force This is pretty self explanatory. AP carries need AP. I take the per level runes over the flat runes, because once you reach mid/late game, they start topping out.

Greater Glyph of Force This is pretty self explanatory. AP carries need AP. I take the per level runes over the flat runes, because once you reach mid/late game, they start topping out. Greater Quintessence of Fortitude As I previously stated, Cho'Gath is a tanky champion by nature. These Quints just make him a bit more tanky, so that you can survive early game and do some serious damage.

Ignite While I'm sure many people will find this odd, I don't take flash. Ignite, in combination with Exhaust, can completely devastate an opponent early to mid game. Being fed pre-late game is a huge part of being AP Cho'Gath. Exhaust Exhaust is a great choice for AP Cho'Gath. If you had to replace either of the spells, I would choose ignite. There are multiple benefits to this. One being an easier target to hit with your Rupture. This can make a huge difference in a gank.

_____

Flash The cookie cutter summoner spell. Has defensive and offensive uses. Usually to initiate or escape ganks. Replace ignite with this if you would like to.

This is your bread and butter spell. It deals massive damage, is AoE, has a knock-up, and has quite a long range.

I've seen many comments about not maxing Rupture first. Here, and on every other Cho'Gath guide. There is a chapter on it later on.

• Try to aim where your target will be after the delay, otherwise, its a waste of mana, a cooldown, and if you're firing from the bush, the element of surprise.
  
  
• Try to place the centerpoint of this spell under a minion, tower, creep, wall, tree, hell, even another champion! Just don't let the "dust" be seen, as it is an obvious indicator to move.

---

AoE Silence. Basically, you can use this while running away, running in for a gank, or just for extra damage. In teamfights, save it for a support!

• Try to get creeps and Champions in its radius, as to be most effective.
  
  
• In a teamfight, try to use this on the enemy healer/AP Carry.

---

Your farming and pushing tool. This can decimate minions in mere seconds late game. Can also make your auto attacks very punishing to other champions. (This basically is what makes you scary. As an AP carry, this gives your auto attacks power, and your spells power.)

• Turn it off near turrets, otherwise you may hit a champion and get unwanted turret aggro.
  
  
• Be careful not to overextend when you use this, otherwise you may find their jungler sitting behind you!

---

This is your ultimate. Note how it deals true damage, which breaks through shields, armor, magic resistance, etc. This will hit HARD.

• You can use this on blue or red buff (After they drop to 999 hp please, if it is even at 1001 on a minion, you still won't get a stack! Nothing more annoying than a wasted ultimate.
  
  
• Use this when enemy champions are at about 1/4 health, and you're guaranteed a kill.
  
  
• This should always be on cooldown until you have 6 stacks. If you don't, use it on minions in the lane. It may seem like a waste, but the 900 extra hp at level 16 is worth it.

Doran's Ring Provides health, Ability Power, and mp5s. One of the most common starter items, and in my opinion, the best for Ap Cho'Gath. Sapphire Crystal Another option, in case you find yourself spamming your spells a lot more than usual.

_____

Amplifying Tome If you feel like you need more power in the start, or you just want to build into Hextrech Revolver faster, you can go with this option. Make sure you also get a Health Potion! Doran's Shield You can grab this if you want to be more tanky, although, I recommend visiting another guide if you want to go tank.

Sorcerer's Shoes As I stated earlier, Cho'Gath isn't naturally made as an AP carry, so we must work around his weaknesses, and get some magic penetration. Rylai's Crystal Scepter Provides the power and slows you need to deal damage, as well as the health you need to survive. You could essentially replace this with Rod of Ages if you wanted to.

_____

Will of the Ancients This is where you start to shine. This item will make you much harder to kill, and well as much harder to withstand. Your Rupture should be hitting for 4-5 bars of their health at this point. Rabadon's Deathcap The cookie cutter item for any and all AP carries, provides the damage you need to transition into late game while staying with the game. If you aren't fed at this point, you're doing something wrong.
