How to win the jungle race as Jarvan IV against Karthus · Matchup data reviewed on patch 26.15
Read from Jarvan IV's seat: the race windows this plan plays for against Karthus.
| Stage | Read | Why |
|---|---|---|
| Level 1 Clear | Jarvan IV Dominant | Dragon Strike's flag-toss poke chips anyone holding a buff pit, while Lay Waste melts camps at record pace. Only one of those wins at the first buff, so press it: take the level-1 crossing, then leave with a camp and a chunk of their health bar. |
| Level 2 Skirmish | Jarvan IV Dominant | The E-Q knock-up gives a clean engage-disengage trade most kits can't answer. Wall of Pain slows cover their disengage, and with one camp still up on both sides that is not an answer. Take the level-2 skirmish and make Karthus path away from the camps you want. |
| Level 3 Route | Jarvan IV Dominant | The full flag-drag combo plus Golden Aegis shield is a flexible level-3 duel. There is no version of this Karthus wins right now — Lay Waste melts camps at record pace, and that folds at the opening scuttle. Show on their side of the river and take the first scuttle and the gank window behind it. |
| Levels 4-5 Macro | Jarvan IV 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 | Cataclysm Favoured | Cataclysm cages the duel on your terms — flag-drag in and wall them off. Requiem finishes you from anywhere — every low-HP recall is a coin flip now — respect that one window, but the six-spike comparison favors you: take the post-6 duel whenever HP bars start even. |
| First Item Spike | Sundered Sky / Eclipse | Completing your core item triggers a massive damage, health, and burst 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 | 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 E attack speed and passive 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.
