How to win lane as Sivir against Kog'Maw · 46.92% win rate (1,709 Emerald+ games, lolalytics, sampled July 2026) · Matchup data reviewed on patch 26.15
His curve needs waves you intend to delete — shove the metronome, shield the all-in, and out-tempo the scaling.
Track: Kog'Maw's W — Bio-Arcane Barrage (17s cooldown). The range + shred window IS the champion — disengage for its eight seconds, fight the gaps.
Read from Sivir's seat: which stage windows this plan plays for against Kog'Maw.
This is Sivir's own plan; across 1,709 pooled games the lane is leaning Kog'Maw.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Sivir | Level 1 favours you because Sivir's Boomerang Blade and steady auto-range beat an immobile Kog'Maw with no early trade pattern. |
| Level 2 | Sivir | Level 2 favours you as Ricochet lets you win the wave and any bump while Kog'Maw only has Caustic Spittle poke. |
| Level 3 | Sivir | Level 3 favours you since a full Q-W-E kit lets you dictate trades and Spell Shield blanks his slow for a free reset. |
| Levels 4-5 | Sivir | Levels 4-5 favour you because Kog'Maw is still immobile and pre-item, so you punish every overstep before his DPS arrives. |
| Level 6 | Sivir | Level 6 favours you as On the Hunt's speed and attack speed let you run down a dash-less Kog'Maw before his on-hit item lands. |
| First item | Kog'Maw | First item favours Kog'Maw because completed Bio-Arcane Barrage on-hit gives him range and DPS you can't match. |
| Two+ items | Kog'Maw | Two-plus items favour Kog'Maw since stacked on-hit attack speed out-DPSes your single-target output in any straight race. |
You own levels 1-5: Kog'Maw is a slow, immobile artillery marksman with no early trading tools beyond Caustic Spittle poke, and your Boomerang Blade plus Ricochet let you win any extended exchange while Spell Shield blanks his Q for a free MR shield and mana refund. Shove the wave and force him to last-hit under threat. He has no early trading tools and no escape, so take the wave and pin him under tower where his short range costs him gold. Boomerang him at every walk-up. Save Spell Shield for the moment his support steps in, and take plates rather than chasing a kill that is not on offer.
