Read from Xayah's seat: which stage windows this plan plays for against Karthus.
This is Xayah's own plan; across 852 pooled games the lane is leaning Xayah.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Xayah | Karthus has no auto threat and must stand still to cast Q, so your poke wins level 1. |
| Level 2 | Xayah | At level 2 your combo trade punishes his stationary Lay Waste casts. |
| Level 3 | Xayah | By level 3 your Q-into-W out-damages his poke and he can't answer. |
| Levels 4-5 | Xayah | Through levels 4-5 his immobile frame folds to your E root threat. |
| Level 6 | Xayah | Your level 6 R goes untargetable through his Requiem, negating his ult entirely. |
| First item | Xayah | At one item your E root plus support CC deletes him before his E Defile ramps. |
| Two+ items | Xayah | In 2+ item fights your R dodges Requiem and your sustained AoE beats his zone control. |
Levels 1-2 are yours: Karthus has no auto pressure and must stand still to aim Q Lay Waste, so walk up and poke with Q Double Daggers whenever he commits to a cast. Stay behind your minions so his Q hits creeps instead of you, and deny him the free scaling he wants. Standing still to aim is the whole of his early game, and standing still on prepared ground is the whole of yours. Poke him with daggers whenever he reaches for a last-hit. Hold the callback for the beat after his wall, and crash the wave for a plate instead of diving him.
