Read from Seraphine's seat: which stage windows this plan plays for against Karthus.
This is Seraphine's own plan; across 1,545 pooled games the lane is even.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Seraphine | Karthus is immobile and Q-reliant, so your level-1 poke wins. |
| Level 2 | Seraphine | At level 2 your Q/E out-trade his fragile early body. |
| Level 3 | Seraphine | Level 3 lets you all-in him before his AP scaling arrives. |
| Levels 4-5 | Even / skill | Level 4 is even as his Defile and your poke balance out. |
| Level 6 | Karthus | Level 6 tilts to him: Requiem and Death Defied grow his threat. |
| First item | Karthus | First AP item makes his Lay Waste and Defile out-damage you. |
| Two+ items | Karthus | Late game his AoE zoning and global burst hard-outscale you. |
You win levels 1-3: Karthus is immobile and depends on landing Lay Waste, so your longer-uptime Q poke and E slow out-trade him and punish his fragile early body whenever his Q is down. He is immobile and has to stand still to cast, so poke him whenever his Q is down and let the notes stack off the wave. Beat Drop lands on a champion with no dash almost every time. Shield through the Defile chip and take the plate rather than chasing him under tower.
