How to win the jungle race as Ivern against Karthus · Matchup data reviewed on patch 26.15
Read from Ivern's seat: the race windows this plan plays for against Karthus.
| Stage | Read | Why |
|---|---|---|
| Level 1 Clear | Respect Karthus | Lay Waste melts camps at record pace, and Ivern has no clean answer to it at the first buff — isolated Lay Waste double-damage adds up fast if you stand in his Defile zone. Close the gap immediately — at melee range his Q damage halves and he folds, and give up your opening camps rather than the kill. |
| Level 2 Skirmish | Respect Karthus | The window on the second camp belongs to Karthus: Wall of Pain slows cover their disengage. Your own line is real — Brushmaker poke from your own brush is your only legal trade — but it arrives second here. Close the gap immediately — at melee range his Q damage halves and he folds, then refuse the level-2 skirmish. |
| Level 3 Route | Respect Karthus | At level 3 this window belongs to Karthus: Lay Waste melts camps at record pace, and isolated Lay Waste double-damage adds up fast if you stand in his Defile zone. Close the gap immediately — at melee range his Q damage halves and he folds. Give up the level-3 river fight and bank tempo on the opposite side of the map. |
| Levels 4-5 Macro | Respect Karthus — Path Opposite | You lose the 4-5 duel. He out-farms the map through 4-5 — Defile clears at a rate nobody matches and Requiem is coming — so let them have that half of the map and cash the other half faster. |
| Level 6 Breakpoint | Respect Karthus's R | Karthus wins the breakpoint outright — Requiem cashes their farm lead into cross-map kills, and Requiem finishes you from anywhere — every low-HP recall is a coin flip now. Base at higher HP thresholds and remember Death Defied still kills over his corpse, then trade objectives cross-map until your items land. |
| First Item Spike | Utility Item Spike | Your first utility items multiply your shields and roots into team-wide stat advantages. Camps remain free, so your gold curve funds vision and gifts without losing item pace. Force nothing; enable everything — Karthus cannot counter-jungle a grove economy. 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. |
Mark both your buffs and the adjacent small camps, then path toward your first gank angle while the groves cook. Karthus's start side only matters for where you place the minute-two deep ward — you fear no invade because there is nothing to invade. Karthus has the fastest clear in the game with Lay Waste and Defile, and he will always be a level ahead if left alone.
