How to win lane as Swain against Karthus · 52.61% win rate over 211 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Swain | Level 1 Karthus has no trade beyond Q snipes and a squishy body, so your walk-up makes it Swain's. |
| Level 2 | Swain | Level 2 you punish his melee range behind minions before his poke ramps — Swain ahead. |
| Level 3 | Swain | Level 3 your E-Q all-in out-trades a farming Karthus with no self-peel. |
| Levels 4-5 | Swain | Levels 4-5 you keep bullying his body and denying scale, staying favoured. |
| Level 6 | Swain | Level 6 Demonic Ascension walks him down since Requiem is a global finisher, not a duel tool — Swain spike. |
| First item | Karthus | At one item his Lay Waste one-shots minions and chunks you from safety, so his poke-scale plan takes over — Karthus. |
| Two+ items | Karthus | Late his Defile AoE, Q spam, and after-death damage beat your single-target dive, so it stays Karthus. |
Levels 1-2 you dominate a farming Karthus: he has no early trade beyond Lay Waste (Q) snipes, so walk up behind minions to eat his Q on creeps, land Nevermove (E) into Death's Hand (Q), and punish his squishy melee-range body.
