He pokes the farm you need — rockets match his range, chompers match his picks, and your DPS dwarfs his rotation.
Track: Karthus's R — Requiem (200–160s cooldown). The global execute — recall above the red line and track it from his level 6 on.
Read from Jinx's seat: which stage windows this plan plays for against Karthus.
This is Jinx's own plan; across 2,780 pooled games the lane is leaning Jinx.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Level 1 is even before Karthus can spam Lay Waste to out-poke you. |
| Level 2 | Karthus | Level 2 favours Karthus as Q ranks let him zone you off the wave. |
| Level 3 | Karthus | Level 3 stays Karthus's with Q poke plus W-shred dominating trades. |
| Levels 4-5 | Karthus | Levels 4-5 remain his window as his AP poke out-damages your weak early. |
| Level 6 | Karthus | Level 6 favours Karthus whose Requiem adds execute pressure you can't answer. |
| First item | Karthus | At first item Karthus still edges you with fast AP scaling and zone control. |
| Two+ items | Jinx | At two-plus items Jinx flips it: you delete a squishy, escape-less Karthus and out-DPS him. |
Level 1 is even before Karthus has Q ranks to spam. He can't yet out-poke you and you contest the wave with your minigun range, so grab clean last-hits and avoid giving him easy double-hit Q setups on you and a minion. He wants to stand still and last-hit, so rockets on the wave are worth more than any poke you try to land on him. Push, take the plate, and let his mana pay for your tempo. Stay off the Defile ring while you are clearing, because chip you cannot heal is how this lane goes wrong.
