so this build... what can i say, when played well can produce some serious dmg to any champion, and also is so fun to play <3. If ya dont like dont blame me i never made you try it :D.

I chose Flash cause Kog'maw aint got that many ways to excape. Also if yer foe is trying to run away it might give you those few extra seconds needed to get him dead.

Next we have Ignite obviously to finish people in early game.

secondary summoner spells i picked Ghost and Exhaust for some survival. if ya pick exhaust be sure to take the mastery for it too.

Icathian Surprise - Often said to be an OP passive and maybe it is just a lil :). awsome for payback.

Caustic Spittle - nice dmg and armor/magic resistance reduction. works great against tanks combined with Bio-Arcane Barrage.

Bio-Arcane Barrage - awesome tank shredder as i said earlier.note: take this at lvl 4 if you lane against a tank.

Void Ooze - awesome dmg and also the only thing which might save your life if you aint got no survivability summoner spells.

Living Artillery - WHEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEHW SHPLASH "you have slain an enemy"

i pick Doran's Ring despite the fact it cant be built to anything cool later on 'cause its dem stats are juicy at start. Sorcerer's Shoes are obvious pick next because this is an abi koggy. Mejai's Soulstealer is needed to get fast for dem stacks. if you notice yourself not getting stacks you mite wanna switch this to Banshee's Veil or Zhonya's Hourglass. Then we pick up Tear of the Goddess to stack up a lil mana. going to Catalyst of the Protector for healt/mana. then make these Rod of Ages and Archangel's Staff. Then we can finally get to the Good old Rabadon's Deathcap for pure abi power awesomeness. Lich Bane seals the deal with its juicy passive.

i'll be ending this explanation here ty hope ya like it, RAWR and other shizzle.
