ok thx for advice yea i considered the ap per lvl runes as well and thx for the advice on the items i didn't realy know that

yea i made bthe changes in the build ^^
btw the items are optional but those are the best

Hey, I'm here due to your referral on my build, thanks for rating up btw :)

There's just a couple of points I'd like to make: It's much better if you just put the whole items and let the users chose the sub-items mainly because it means that in the Mobafire Statistics where it lists your attack damage , etc is more accurate; when you list all the sub-items it only recognises them and colours them, it doesn't disinclude them in the statistics so you end up with A LOT more Attack damage % than you actually have :p
And also: If you ever get AP runes, get AP per level runes, they are so much better @ level 18 (Glyphs give 27.56 AP @ level 18) and 9 AP doesn't even make a difference @ level 1.
Other than those things I agree. I think that it's an incredibly wise move to get Boots of Swiftness, and could be considered a great choice for the MS Quints (At least you'll be faster than every1 else with Boots of Swiftness), because Kog'Maw NEEDS movement speed to catch up with his prey and maintain his barrages with Bio-Arcane Barrage and Living Artillery.
The Items are great for that of an AS/AD Kog'Maw and if you simply improved it by only adding a sub-item when you need to get it earlier in the sequence than the whole item (EG get boots, then a zeal, then berserker's Greaves.) and changing your AP runes into AP/level runes. I also think Ignite's good because getting those early kills is awesome nice, but Exhaust/Ghost or Ignite/Ghost is a good choice if you don't want heal (or Ignite). I'm reluctant to use the Ability Order but then again I'm not much of an expert on Kog'Maw although I do play him regularly I usually go AP. Kog'Maw is the king of kill steals ;D

Once improved, great build! :) +1
