Read from Swain's seat: which stage windows this plan plays for against Dr. Mundo.
This is Swain's own plan; across 1,084 pooled games the lane is Dr. Mundo-favoured.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Both champions are at their weakest here — Mundo's passive regen absorbs your Q bolt poke and you have no root yet, so the stage is a wash; last-hit at safe distance. |
| Level 2 | Swain | Your E root comes online and lets you pull him out of his Heart Zapper heal-back window before it pays out — first genuine threat stage is yours. |
| Level 3 | Swain | W-slow into E-root into Q-burst gives you a three-ability setup Mundo cannot dodge without a dash he does not own — this is your clearest damage window in the lane. |
| Levels 4-5 | Swain | Infected Bonesaw ranks up on a 4s cooldown and his passive regen refunds your chip faster than fragments stack, so 4-5 slips to him unless Grievous Wounds is already online. |
| Level 6 | Even / skill | Both ultimates are live, but Demonic Ascension holds indefinitely as long as you keep draining a champion inside 650 range — bait Maximum Dosage out first and level 6 is yours. |
| First item | Even / skill | Your first item sharpens W poke, but his goes into raw health and his own regen — the first-item stage belongs to him, and the window to convert your lane lead is closing fast. |
| Two+ items | Dr. Mundo | Warmog's passive lets Mundo heal to full between every trade, rendering your accumulated Soul Fragment HP irrelevant — apply Grievous Wounds before Demonic Ascension or avoid the 1v1 entirely. |
At Level 1 both of you are weak — Mundo's Heart Zapper and passive regen give him baseline sustain that your raw Q bolt damage can't punish yet, so accept last-hitting under mild Infected Bonesaw harassment and do not walk into his Q lane-clear pattern. At Level 2 your E goes live and the equation tilts: bait him into a short auto-trade to spend his Heart Zapper damage store, then immediately land the E-root into Q cone to chunk him before the stored damage repays. By Level 3 you have the W-into-E setup — drop Vision of Empire on his side of the wave so he has to choose between taking the slow (and walking into your E) or dodging away from CS; either way you win the exchange if your E connects.

Swain takes Arcane Comet on the Sorcery tree with Manaflow Band, Transcendence and Scorch, and Inspiration secondary (Biscuit Delivery and Cosmic Insight) vs Dr. Mundo.
Start Doran's Ring + 2 Health Potions and back for Oblivion Orb (≈800g) — cuts his healing. Build Liandry's Torment (drain + burn) first, then Rylai's / Riftmaker, with Sorcerer's Shoes.
