Hey guys i've been playing for a while and i'm just over level 9, i'm doing good, usually 6/5/8ish and having no difficulty keeping my team afloat however, right now i'm trying to go from noob good, to normal player good, and i need to know what i should buy for better damage (i play him as a nuker which is really good apperently) and i can hold my own with how i play but i really wanna step it up a level, any input would be awesome and very greatly appreciated, also any friend requests so i can see other play styles of higher level characters would be awesome

What playstyle do you prefer with Kog' Maw pure AD, pure AP, hybrid of AD and AP, etc?

Kog'Maw is pretty hard to master, I would really recommend a simpler champion for starting out.

Caster is good if you can land his R and E consistently. He also really benefits from Golem buff, and you want to try and have it at all times.

Here's a video of Kog'Maw at higher level of play. I have not seen it, so I don't know how useful it is for you, but I hope it helps. You might also want to check out builds and guides at leaguecraft.com and mobafire to get a better understanding of Kog'Maw.
