Read from Dr. Mundo's seat: which stage windows this plan plays for against Sejuani.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Your regen and Q poke beat Sejuani's low-damage, mana-hungry level 1. |
| Level 2 | Even / skill | Level 2 is a coin-flip on who lands the first Permafrost, so it's skill. |
| Level 3 | Dr. Mundo | At 3 your Q sustain lets you shove and deny her CS. |
| Levels 4-5 | Dr. Mundo | Levels 4-5 you hold prio and walk her down 1v1. |
| Level 6 | Even / skill | At 6 her R is a teamfight tool, not a duel win — it's even. |
| First item | Dr. Mundo | Your first tank item keeps you ahead in the 1v1 she can't burst. |
| Two+ items | Even / skill | Late, her chain-CC engage utility rivals your frontline, so it's skill-dependent. |
You have the individual edge early. Sejuani is a utility tank with low damage and a thin mana pool, so tank her Arctic Assault-Permafrost, poke with Q Infected Bonesaw, and shove her under tower to deny CS. Level 2 is skill-dependent on who hits first, but you sustain any trade she starts.
