The jungle race — the windows in Karthus's plan

Read from Karthus's seat: the race windows this plan plays for against Warwick.

StageReadWhy
Level 1 ClearDanger — Avoid WarwickHard no-contest for Karthus at level 1: Eternal Hunger sustain means they win any fight where both sides arrive off full camps, and Q sustain and Blood Hunt frenzy out-heal your damage the moment you drop below half. Never fight him while low — his W tracks your blood trail; disengage above 50%. Path opposite, ward your entrances, and let the clock carry you to your own spike.
Level 2 SkirmishDanger — Avoid WarwickQ sustain and Blood Hunt frenzy out-heal your damage the moment you drop below half. Blood Hunt (W) attack speed plus Q healing out-sustains every trade pattern on top of that, so level 2 is a straight stat check Karthus loses — never fight him while low — his W tracks your blood trail; disengage above 50%, and give the river vision-line respect.
Level 3 RouteDanger — Avoid WarwickWarwick out-classes you at the opening scuttle — Eternal Hunger sustain means they win any fight where both sides arrive off full camps, and Q sustain and Blood Hunt frenzy out-heal your damage the moment you drop below half. Give up the level-3 river fight, full-clear away from them, and trade map pressure instead of health.
Levels 4-5 MacroDanger — Avoid WarwickWarwick owns 4-5 outright. He tracks blood trails through 4-5, so any laner below half is a gank he reaches faster than you expect, so treat every crossing as theirs and take the camps they are furthest from.
Level 6 BreakpointRespect Warwick's RInfinite Duress suppresses you through the fight while his sustain out-lasts your burst — Karthus loses the straight post-6 duel. Hold a dash or hard CC for the R leap — it is interruptible mid-flight, and shift your pressure to the side of the map Infinite Duress is not on.
First Item SpikeLiandry's SpikeLiandry's plus your farm lead makes Defile standoffs unwinnable for Warwick 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. Warwick's first item is where the healing stops being sustain and starts being more than your damage can out-pace.
2+ Items ScalingKarthus Favoured — Wins LateThe late game is yours. Remember what Warwick still is at full build — he suppresses a carry for the length of the fight and out-heals your answer — and take the fights that do not let it matter.
