this may be the most important skills to learn when playing as cho'gath. The trick is to only use when your enemy is right by you
This makes it so he does have enough room to escape in time
Or use it when his gap closers are down
Or use it when he has only one path to take
Remeber to lead your enemy and not hit it right under him or he will just walk away.
use all your spells to deal damage not farm creeps

this is easy to understand
USE IT WHEN THE CHAMPION"S SKILLS ARE ABOUT TO BE READY AGAIN OR PREVENT THE USE OF THE SKILLS
when a riven or gp and going toe to toe to me i scream at them right b4 they stun or eat their way out of my spikes (q,e).
They may even say OMFG SO CLOSE.
that is what you want

if your fighting any champion farming your R is a must need. It will make you fear unkillable and will make you move faster. Faster you say? yes faster.
Feast your champion b4 you have ingite on yes it is a waste of your cd but your enemy will want to wait until you ingite so he can flash away.
Also NEVER KILL STEAL YOUR CARRIES
this is the worst thing to do
cause a cho'gath cant deal all the damage but is such a threat that unchecked means you just lost 2 champions in 4 secounds with out even knowing
another good tip is to feast their ad carry out of nowhere in a team fight so you can make him get back OR DIE

After playing Dota for 2 years Hon for a month and LoL for 2 years. I have learned that 657 wins with cho'gath is because ap ISNT THE WAY TO GO.
Why not ap?
if stuned you are ****ing dead
if silence you deal no damage then you are ****ing dead.
If you wanna try to farm a lane with a high damage or high cc champion you are ****ing dead.
In a normal team fight in a normal ranked game you are ****ing useless...............and dead
With ap cho'gaht you need deathcap and rod or ages which means you do **** cause you either
1 get atnky first and deal no damage
2 get ap burst first and cant tank
or 3 you cant hit your spells and now you are ****ed

remember to farm as much as possible and watch out for ganks 24/7 nobody likes a feeder
if you are ganked be smart juke all the time. Since you are large dont walk in a straight path and hit your q and w when they chase you

Flash ingite/exhuast
Flash is the #1 spell to use it makes it so you flash towards a champion and feast him out of nowhere or get your big *** out of there.
Ingite good vs high stustain champions
Exhaust
easy food for you or your hungry team

Pros
NormalAI
InsaneAI
Phreak
not you
lol
You are a super tank with 4.8k hp and 210 regen
almost never die
good dps
easy to kill Carries or other off tanks

Cons
if you are uniskilled dont try this build
CS and outplaying your enemy player is needed
Being able to land your Q 8/10 times and not kill stealing you team is needed
You will have trouble fighting lee sin and renetkon
warwick shouldnt be a problem idk why
