Read from Karthus's seat: which stage windows this plan plays for against Jhin.
This is Karthus's own plan; across 3,720 pooled games the lane is even.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Jhin | Jhin's auto range and Dancing Grenade out-poke your Lay Waste at level 1. |
| Level 2 | Jhin | At level 2 his fourth-shot crit punishes every walk-up you make to farm. |
| Level 3 | Jhin | Level 3 Deadly Flourish roots let him convert his poke lead into all-ins. |
| Levels 4-5 | Karthus | At levels 4-5 his lane pressure still forces you to farm passively. |
| Level 6 | Karthus | Level 6 Requiem's global snipe answers his stationary Curtain Call and swings tempo to you. |
| First item | Karthus | Your first AP item lets Lay Waste out-DPS his reload windows. |
| Two+ items | Karthus | With two items your AoE Requiem and Defile out-scale his single-target burst in fights. |
Levels 1-2 favor Jhin: his auto range and Dancing Grenade bounce out-poke your Lay Waste cadence, and stepping up to farm eats his fourth-shot crit. Take your last-hits with Lay Waste during his reload and step nowhere near his range while the fourth round is chambered. His flower is what makes a support engage land, so keep the wall for that rather than for waveclear. Play the farm, watch the mana, and let the lane push into you.
