Ignore his E-counterstrike with Q chunks, out-sustain the duel with R, and he can't out-DPS your regen.
Track: Jax's E — Counter Strike (17–9s cooldown). Dodges autos + stuns. Bait it.
Read from Dr. Mundo's seat: which stage windows this plan plays for against Jax.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Dr. Mundo | Level 1 is yours: no ult Jax loses the first melee trade to your kit. |
| Level 2 | Dr. Mundo | Level 2 favours you as your W and heal outlast his thin sustain. |
| Level 3 | Dr. Mundo | Level 3 stays yours — E and Q punish him while his E is down. |
| Levels 4-5 | Dr. Mundo | Level 4 remains yours since he still has no ult to flip trades. |
| Level 6 | Even / skill | Level 6 flips to Jax: Grandmaster-at-Arms adds resists and a magic proc. |
| First item | Jax | On first item his BorK spike and E stun out-duel your tank build. |
| Two+ items | Jax | With two-plus items Jax out-DPSs and out-tanks you, so late is his. |
Levels 1-4 are yours — Jax has no ult yet and thin sustain, so E Blunt Force Trauma onto him and Q him whenever his E Counter Strike is on cooldown, and your W plus self-heal simply outlast his early trades.
