Read from Dr. Mundo's seat: which stage windows this plan plays for against Cassiopeia.
This is Dr. Mundo's own plan; across 637 pooled games the lane is Dr. Mundo-favoured.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Cassiopeia | Cassiopeia's Q poke and E spam shred your no-MR body at 1 — her level. |
| Level 2 | Cassiopeia | At 2 Miasma's slow keeps her poking, but your regen holds — Skill. |
| Level 3 | Cassiopeia | At 3 ramping E (Twin Fang) damage out-trades your regen — Cassiopeia-favoured. |
| Levels 4-5 | Cassiopeia | Through 4-5 her mana drains while your passive regen holds — Skill. |
| Level 6 | Cassiopeia | At 6 face away from Petrifying Gaze and it only slows — Skill. |
| First item | Dr. Mundo | By 6 you dodge R, close on minions, and your R heal out-paces her — Dr. Mundo. |
| Two+ items | Dr. Mundo | By two items her chip bounces off MR and you walk her down — Dr. Mundo. |
Cassiopeia zones you hard at 1-5 — Q (Noxious Blast) poke plus W (Miasma) grounding stops your gap-close while E (Twin Fang) spam melts your regen. Buy an early MR component, dodge Q, and just soak XP; you can't reach her yet.
