Read from Zac's seat: which stage windows this plan plays for against Dr. Mundo.
This is Zac's own plan; across 870 pooled games the lane is even.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Dr. Mundo | Dr. Mundo edges level 1 with passive tankiness before your kit is online. |
| Level 2 | Dr. Mundo | Still Mundo's beat at 2 — his cleaver poke out-trades your bare auto. |
| Level 3 | Zac | Zac takes over at 3 as W percent-HP damage bites his big pool. |
| Levels 4-5 | Zac | Levels 4-5 stay blue: your online kit out-trades his cooldown-gated cleaver. |
| Level 6 | Even / skill | Level 6 evens — Maximum Dosage heals back a cut of missing health. |
| First item | Zac | First item favours Zac as Sunfire plus W out-spikes his early tank build. |
| Two+ items | Zac | Zac stays ahead with items thanks to R engage range and percent-HP W scaling. |
Levels 1-2 tilt slightly to Mundo: his passive tankiness and Bonesaw (Q) cleaver let him bully you before your Q and W come online, so soak XP and don't force early trades.
