Read from Dr. Mundo's seat: which stage windows this plan plays for against Olaf.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Olaf | Olaf's Reckless Swing true damage ignores your HP stacking, so level 1 is his. |
| Level 2 | Olaf | At level 2 his axe-pickup slow keeps him glued to you and winning trades. |
| Level 3 | Olaf | Level 3 his true-damage trades still beat your health-cost Q and sustain. |
| Levels 4-5 | Olaf | Through levels 4-5 his damage ignores your armor and HP, keeping him ahead. |
| Level 6 | Olaf | Level 6 Ragnarok makes him CC-immune and out-DPS's your R, his strongest window. |
| First item | Olaf | Even at first item his true damage and lifesteal keep the lane uphill for you. |
| Two+ items | Dr. Mundo | Only at 2+ items does your raw HP finally outlast his E cooldowns — late flips to you. |
Olaf brutalizes you levels 1-3: Reckless Swing (E) deals true damage that your entire HP-stacking identity does nothing against, and re-collecting his Undertow (Q) axe keeps you slowed and pinned so you lose every short trade.
