How to play Kog'Maw in ARAM Mayhem

Kog'Maw is a solid, middle-of-the-pack pick in ARAM Mayhem on patch 26.21: tier B, #107 of 173 champions, with a 48.6% win rate over 1,279,170 games.

Kog'Maw's damage is mixed (22% physical, 63% magic), which makes it awkward for the enemy team to itemize against. It deals 44,650 damage to champions in an average game, more than most champions, so play to stay alive and keep hitting.

Most Kog'Maw players go On-hit (35% of games), but the AP path, ability power items, is ARAMKit's top-ranked build: Shadowflame, Dusk and Dawn and Rabadon's Deathcap, with a 49.5% win rate. On this build 46% of players skip boots and spend the slot on another item.

The cards that do best on Kog'Maw are Back To Basics, Urf's Champion and Hand of Baron. Cards built around movement speed fill most of the top of its list, followed by ability haste. Most of its S-tier cards are prismatic, so a prismatic offer is often the pick that shapes the game. Skip Holy Snowball and Rite of Ascension when you can: they do worst on Kog'Maw. A pair to look for: Blue Barrier with Weapon of Destiny.

Take Flash and Ghost (64% of players). Max W (Bio-Arcane Barrage) first, then Q, then E.
