How to win the jungle race as Karthus against Rek'Sai · Matchup data reviewed on patch 26.15
Read from Karthus's seat: the race windows this plan plays for against Rek'Sai.
| Stage | Read | Why |
|---|---|---|
| Level 1 Clear | Danger — Avoid Rek'Sai | Rek'Sai out-classes you at the first buff — Fury-fueled Q autos clear fast and win the first raptor fight, and an Unburrow knock-up from an unseen tunnel starts every fight on her terms. Skip the level-1 crossing, full-clear away from them, and trade map pressure instead of health. |
| Level 2 Skirmish | Danger — Avoid Rek'Sai | Do not be seen on the second camp: an Unburrow knock-up from an unseen tunnel starts every fight on her terms. On top of that, the Unburrow knock-up gives a free engage on anyone walking their tunnels, so they get there first. Ward her tunnel entrances — if you can't see the burrow line, don't walk the river. Refuse the level-2 skirmish and farm the opposite quadrant until your spike lands. |
| Level 3 Route | Danger — Avoid Rek'Sai | Hard no-contest for Karthus at level 3: the full tunnel network plus knock-up means they dictate where every fight starts, and an Unburrow knock-up from an unseen tunnel starts every fight on her terms. Ward her tunnel entrances — if you can't see the burrow line, don't walk the river. Path opposite, ward your entrances, and let the clock carry you to your own spike. |
| Levels 4-5 Macro | Danger — Avoid Rek'Sai | Do not be seen by Rek'Sai at levels 4-5 — you lose every exchange. Full-clear away from them, ward your entrances, and trade map pressure, not HP. |
| Level 6 Breakpoint | Respect Rek'Sai's R | Rek'Sai wins the breakpoint outright — Void Rush executes anyone they have prey-marked, and Void Rush's untargetable execute finishes any trade that drops you low. Stay above execute range — a marked duel at half HP is already over, then trade objectives cross-map until your items land. |
| First Item Spike | Liandry's Spike | Liandry's plus your farm lead makes Defile standoffs unwinnable for Rek'Sai and your Requiem chunks brutal. You now solo Dragons early with W-E pit control. Force the enemy to fight inside your aura at every objective — or concede them on the clock. Rek'Sai's first item is a real jump in duel power, but it is also close to the end of her scaling curve. |
| 2+ Items Scaling | Karthus Favoured — Wins Late | Rek'Sai falls off relative to you — from two items on you win the raw stat check, even though he executes anything below the Void Rush threshold from across the map. Drag the game long and force the 1v1s. |
Start blue-side regardless of map side preference arguments — your mana economy is your clear speed. Track Rek'Sai's entry only to know which half of your farm to bank first; you race nobody, you out-pace everybody. Rek'Sai clears fast on Fury-fuelled attacks and Furious Bite, and her tunnels make her map speed better than her clear suggests.

Not exactly — Rek'Sai pressures 5 of the 7 windows, so Karthus is playing catch-up and has to lean on the map.
