This is Karthus's own plan; across 1,216 pooled games the lane is leaning Vayne.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Karthus | Karthus Q out-ranges Vayne's short auto range so you poke freely at level 1. |
| Level 2 | Karthus | At level 2 your Q rank plus early E threat still beats Vayne's no-poke laning. |
| Level 3 | Karthus | Level 3 Q max lets you chunk her every time she steps up to farm. |
| Levels 4-5 | Karthus | Levels 4-5 you keep the poke lead before Vayne's Botrk spike arrives. |
| Level 6 | Karthus | Level 6 Requiem executes her from anywhere, adding kill pressure she can't match. |
| First item | Karthus | First-item Q burst out-damages her single-target Botrk all-in. |
| Two+ items | Karthus | With 2+ items your poke and Death Defiance passive dominate the 2v2 and teamfight. |
Lay Waste out-ranges every tool Vayne has at levels 1-2; sit behind your caster minions and punish her the moment she walks up to farm, since she has no wave clear and no poke to answer your Q. Keep your mana for last-hits and one or two center-hits per wave rather than shoving. She has no wave-clear and no poke, so Lay Waste simply out-farms her from a range she cannot answer. Keep the mana for last-hits rather than chip. When she walks up, turn Defile on and let your support commit, and keep the wall away from the lane walls so a knock-back has nowhere to stun you.
