How to win the jungle race as Olaf against Karthus · Matchup data reviewed on patch 26.15
Read from Olaf's seat: the race windows this plan plays for against Karthus.
| Stage | Read | Why |
|---|---|---|
| Level 1 Clear | Olaf Dominant | Undertow (Q) spam clears fast and chunks anyone who contests your buff. Lay Waste melts camps at record pace, and before either of you has a second camp down that is not an answer. Take the level-1 crossing and make Karthus path away from the camps you want. |
| Level 2 Skirmish | Olaf Dominant | Vicious Strikes (W) sustain means you leave every camp healthier than they do. There is no version of this Karthus wins right now — Wall of Pain slows cover their disengage, and that folds on the second camp. Show on their side of the river and take the second buff and the tempo that comes with it. |
| Level 3 Route | Olaf Dominant | Full Q-W-E with Reckless Swing true damage means nobody on the roster out-brawls this. Later in the game this bites, because isolated Lay Waste double-damage adds up fast if you stand in his Defile zone. But as the first scuttle timer lands none of it is online, so take the level-3 river fight and tax every camp Karthus concedes. |
| Levels 4-5 Macro | Olaf Dominant — Keep Fighting | You are the stronger side all through 4-5. Karthus knows it — he out-farms the map through 4-5 — Defile clears at a rate nobody matches and Requiem is coming — so shadow that side of the map and make them fight you anyway. |
| Level 6 Breakpoint | Ragnarok Favoured | Ragnarok's CC immunity turns every post-6 skirmish into a stat check you win, while Requiem cashes their farm lead into cross-map kills. You win the breakpoint against Karthus, not the whole game — cash it on the first objective after both sides hit six. |
| First Item Spike | Ravenous Hydra Spike | Completing your core item triggers a massive physical damage, wave clear, and lifesteal multiplier that completely overpowers traditional brawlers or isolated targets. Karthus' first item is where Lay Waste stops chipping and starts taking a third of a health bar per cast. |
| 2+ Items Scaling | Danger — Karthus Outscales | You lose the long game outright: he deals damage from anywhere and keeps dealing it dead — Death Defied buys the fight, and no build path of yours answers that. Convert every early lead into an objective immediately. |
Start your clear at the Red Buff camp to maximize early continuous damage via Q resets and passive attack speed. Karthus has the fastest clear in the game with Lay Waste and Defile, and he will always be a level ahead if left alone.
