Pro
great solo lane hero
Incridible CC & Interupt
Magnificent creep farmer
Intensive burst
Great survivability skillz

Cons
Lacks mobility
Rapture is fairly easy to dodge

I Usually play Cho'Gath soloing the top lane so i like to carry Ghost & Teleport, the teleport is very neat if you want to keep up your minion farming. For example go back for a catalyst protector early game without losing a tower or geting underlevled.

OTHER OPTIONS
Flash
Exhaust
Ignite

Cho'Gath is an insane farming hero. I always top the creep killing.
First off: Vorpal strike is godly for last hits, and with your passive cornivore you will have a fully great laning capability against almost any setup.

And when you got yourself a mana pool you can aoe a creep wave with Rupture & Feral Scream
Picking up a blue buff can increase your farming limits early game.

My item build is made for a offtank/anti carry Cho'Gath. The summary of what the build gives you is a great health base, intens burst, decent tanks stats.

This is my First guide every so don't be so picky about everything. English isn't my mothers tongue and so i might fail abit on the spelling.
But overall im happy to introduce the way im playing Cho'Gath to people.
