READ THIS..... So this is my first guide...if anyone has a problem please message me or comment if you know I need to improve on something... ChoGath is a hero who i belive is played wrong a lot of the time and this is my interpretation on how he should be played =D Note this is a Solo top Guide

PROS
-Has great in lane sustain with his passive
-Has a disable
-A silence
-A true damage ultimate that make's him really tanky
-Possibly the greats legendary skin in the game
CONS
-cannot carry
-has a learning curve
-can be tough to fight other enemy if you miss your R(so dont put all your skill points in it =))
-becomes very mana hungry very fast if you start spamming spells

9 In Attack
-5 AD and AP when on CD
-a little ap
CD and 10% Magic Pen
21 In Defense
-some Armor and Mr
- Lane sustain even stronger with the extra Regen
-Mo Health
-Move faster
-Take less damage
-MORE HEALTH and lower time beind disabled

Flash
-Offers great utility and lets you RUPTURE ULT KILL
-when in your in a pickle and you gotta get out of there
Ignite
- feast didn't do the job....
-pesky late healers aren't so pesky eh?

REALLY I DON"T KNOW WHY YOU WOULD TAKE ANY OTHER!
Ghost-is a preference...
Smite- Cho is honestly better soloing top
CV-..... Support cho... I think not
Heal- your sustain dosen't need it
Clairvoyance-I guess if your new with Cho gath but really it isnt worth is just dont spam
EXHAUST- actually pretty good but I think ignite and flash work better
Cleanse- how much CC must they have for you to tkae this?
Teleport- not bad again but I dont really like it on Cho Gath
SURGE-maybe..never bothered giving it a chacne
Revive,Promote and fortify-.....

Q-W-R-E Ignite if they are still there

RUPTURE
-should be used to disrupt the enemy team, try to hit the AD carry or AP carry with it
-u can cast it within half of a circle from the middle so it's range is increased a tad bit wont belive how much that helps
-try to use only once every lane..or if the other champ is starting some beef

FERAL SCREAM
- try to hit AP and Support charcters with this..really 3 seconds is a lot =)
-note cost more mana every time you put a point in to it.....
VORPLSPIKES
-good extra damage
-great for farming so put a point early (3)
does splash
FEAST
-AS SOON AS YOU HIT 6 DO THE MATH.. rupture plus feast plus ignite... they dead?
if not eat a minion
-try keep 6 stacks because at level 16 that's an extra 900 health

Honestly............

IF THEY HAVE LOTS OF AP CASTERS GET FORCE OF NATURE O BANSHEES VEIL

IF THEY HAVE LIKE $ AD OR LIKE SUPER FED THEN GET A THORN MAIL BUUUUUUUTTTTTTTTTT ONLY IF THEY SUPER FED OR HAVE STUPID AMOUNT OF AD

IF YOUR FED THEN GET YOUR NORMAL ITEMS FASTER

AD Cho Gath is not a good idea for Ranked
Hybrid CHO GATH..... isnt as good as this ChO GATH....
U can switch the order around of the last few itmes if you want.... depending on how the game is going...also...
LICHBANE- is good BUT I I DONT LIKE IT THAT MUCH SO YOU MAKE AN INFORMED DECISION K?

-your not invincible
-U cant carry
-dont tell riot that cho is Op or they might nerf him =)
-try the build out before down voting it and saying I suck
-idk how to teach somone to last hit
- HAVE FUN
