Read from Heimerdinger's seat: which stage windows this plan plays for against Kog'Maw.
This is Heimerdinger's own plan; across 303 pooled games the lane is Kog'Maw-favoured.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Heimerdinger | You-favoured L1: turret and grenade out-trade the immobile, weak-early Kog'Maw. |
| Level 2 | Heimerdinger | You-favoured L2: compounding poke denies the safe farm he needs to scale. |
| Level 3 | Heimerdinger | You-favoured L3: the E-Q combo punishes his total lack of mobility. |
| Levels 4-5 | Heimerdinger | You-favoured L4-5: turret siege starves his CS and delays his item spikes. |
| Level 6 | Heimerdinger | You-favoured L6: beam UPGRADE and doubled grenade zone him off the wave despite his Artillery. |
| First item | Heimerdinger | You-favoured first item: continued siege delays his two-item Bio-Arcane spike. |
| Two+ items | Kog'Maw | Kog'Maw-favoured 2+ items: W percent-health shred out-DPSes your immobile turret nest. |
Heimerdinger dominates levels 1-2: Kog'Maw has no mobility and a weak early game, so your turret and grenade out-trade him and deny the safe farm his whole scaling plan depends on. He is the ideal grenade target: no dash, no way to leave, and a farming pattern that keeps him still. Plant forward, poke him off the wave, and hold the stun for the moment his support tries to relieve the pressure. Take plates over kills and he never reaches the item timing his whole game is built around.
