Read from Kog'Maw's seat: which stage windows this plan plays for against Swain.
This is Kog'Maw's own plan; across 916 pooled games the lane is Kog'Maw-favoured.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Swain | Level 1 Swain zones your CS with Q bolts and root threat. |
| Level 2 | Swain | At 2 his W-root all-in and self-heal beat your immobile trades. |
| Level 3 | Swain | Level 3 gives him full combo pressure you can't answer. |
| Levels 4-5 | Swain | Through 4-5 his sustain and CC keep the 2v2 his. |
| Level 6 | Swain | Level 6 Demonic Ascension is a kill threat, not a Kog'Maw window. |
| First item | Swain | Even at one item his tanky-AP drain out-durations your squishy DPS. |
| Two+ items | Kog'Maw | With 2+ items your percent-HP W shred finally melts his stacked health. |
Levels 1-2 favour Swain: his Q bolts and looming W root make stepping up to last-hit dangerous, so farm passively behind the wave and give no free roots. A landed root is the whole loss condition, so keep your own minions in the path of it and never step up for a CS you do not need. Void Ooze is what buys you the exit, so hold it. Your steroid arrives before his best window closes, which is what makes the passivity worth it.
