How to win the jungle race as Rek'Sai against Karthus · Matchup data reviewed on patch 26.15
Read from Rek'Sai's seat: the race windows this plan plays for against Karthus.
| Stage | Read | Why |
|---|---|---|
| Level 1 Clear | Rek'Sai Dominant | Fury-fueled Q autos clear fast and win the first raptor fight. Later in the game this bites, because isolated Lay Waste double-damage adds up fast if you stand in his Defile zone. But before either of you has a second camp down none of it is online, so take the level-1 crossing and tax every camp Karthus concedes. |
| Level 2 Skirmish | Rek'Sai Dominant | The Unburrow knock-up gives a free engage on anyone walking your tunnels, while Wall of Pain slows cover their disengage. Only one of those wins on the second camp, so press it: take the level-2 skirmish, then leave with the second buff and the tempo that comes with it. |
| Level 3 Route | Rek'Sai Dominant | The full tunnel network plus knock-up means you dictate where every fight starts. Lay Waste melts camps at record pace, and as the first scuttle timer lands that is not an answer. Take the level-3 river fight and make Karthus path away from the camps you want. |
| Levels 4-5 Macro | Rek'Sai Dominant — Keep Fighting | Nothing about 4-5 helps Karthus here: he out-farms the map through 4-5 — Defile clears at a rate nobody matches and Requiem is coming, while you can take any duel you can reach. Invade on the clear-timer, not on a whim. |
| Level 6 Breakpoint | Void Rush Favoured | Void Rush executes anyone you have prey-marked — chunk first, then commit. Karthus's six is not empty — Requiem finishes you from anywhere — every low-HP recall is a coin flip now. Take the duel from even health rather than from behind, and base at higher HP thresholds and remember Death Defied still kills over his corpse. |
| First Item Spike | Stridebreaker Spike | Completing your core item triggers a massive damage, health, and sticking power multiplier that completely overpowers traditional brawlers. 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 | The clock is your enemy. He deals damage from anywhere and keeps dealing it dead — Death Defied buys the fight, so close the game on the first two objectives you actually win. |
Start your clear at the Red Buff camp utilizing your Queen's Wrath AoE to maximize early clear 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.
