How to win lane as Karthus against Sivir · 50% win rate over 610 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Sivir | Sivir's rank-1 Boomerang and Ricochet shove the wave and let her poke you first at level 1. |
| Level 2 | Sivir | At level 2 her Spell Shield still trivializes your single Q and she controls the wave. |
| Level 3 | Sivir | Through level 3 her push tempo and shield keep her the safer, more threatening laner. |
| Levels 4-5 | Karthus | By levels 4-5 your ranked-up Q out-ranges Boomerang and you win the poke war. |
| Level 6 | Karthus | Your level 6 Requiem executes low Sivir backs that her Spell Shield cannot prevent. |
| First item | Karthus | A completed first item makes your Q+E burst out-trade her raw auto damage. |
| Two+ items | Karthus | In late teamfights your death passive and E melt her grouped comp faster than she can peel. |
Levels 1-2 Sivir is ahead: her Boomerang Blade plus Ricochet push the wave into you and let her poke on the shove while you have only a rank-1 Q, and her Spell Shield eats your first Lay Waste for free. Respect the early shove, farm safely, and don't waste Q into her shield window.
