Sorry I thought I did but it never saved.

No you didn't.

I still like my full AP RoA Bro'Gath ;[ it hasn't failed m yet. Though I agree that RoA is generally too much time/gold investment to actually be useful half the time. But hey if you're stomping them without even having a catalyst yet, why not amirite?

My thought son the build; dat nashors swag. Wit's End is a cheaper better fit for tanky cho. You build NO other AP in your core build so the passive isnt helpful anyway. Thornmail is highly situational as are mobis. overall just a weird *** path.

Also, NEVER BUILD ROD OF AGES ON CHO IN ANY LANE/ROLE.

It's stupid expensive and not worth it. If you want mana sustain, go for a chalice, or if you're mid, athene's for nomicon. If you want more hp, you're doing it wrong, and if you want ap, go for nomicon

Your build doesn't make that much sense. I agree with a lot of points above.

Try dorans shield, dorans ring, ninja tabi (if you're against any ad/auto attackers), frozen heart, spirit visage. It's best to stack resists and rely on your ult for hp

Oh wow you were right about my masteries I fixed that. I have a lot to learn on making a guide user friendly and I understand downvoting this one. Thanks for your input.

- AD masteries on an AP champion? You're doing it wrong. Also not explained in your guide why you would do that.
- No other starting choices mentioned.
- Thornmail is bad. Replace it with Frozen Heart.
- No coding used at all. People don't like it to read walls of texts, even when the information given is golden.
- Nashor's Tooth is pretty meh. You barely get the chance in teamfights to use auto-attacks with Cho'Gath, I'd rather get Rod of Ages to become more tanky and to solve more of his mana problems.
- Sunfire Aegis isn't the best thing either on Cho'Gath.
- Mobility boots aren't the best choice. Mercury's are MUCH better.

I'm sorry, but your build just contains too many errors. -1.
