How to play
General
Playing AP Kog'Maw build, your default rush is Luden's Companion. In cases, when an enemy team is full of tanks and HP stackers, go Liandry's Torment.
Adapt to an enemy team. Are they full of tanks, and they rush tons of Magic Resist? You rush Void Staff as #2 or #3 item to counter MR stacking. Their team has champs with lots of healing? Rush Oblivion Orb as #2 item (upgrade to Morellonomicon as 4th or 5th item).
Somebody is going after you each fight? Always getting ulted by enemy assassins? Rush Zhonya's Hourglass.
Champion
Your classic AP Kog'Maw combo is to Void Ooze (E) to slow them, then keep bombarding them with Living Artillery (R).
If you are sure that you hit Void Ooze (E), you can start using Living Artillery (R) before E animation ends.
Rylai's Crystal Scepter is very good item for AP as it enables you to chain Living Artillery (R). If you hit single R, then you can follow up with more Rs more easily.
Beware of mana! Cost of Living Artillery (R) grows every cast. You need to count stacks, be aware of your mana and know when to drop them, so you can start fresh and start shooting again.
Late in the game, your auto attacks (thanks to AP scaling) are gonna hurt like a truck. You are gonna melt HP stackers, so do not be afraid to do that, if situation allows it.
Tips and Tricks
Riot
