| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Karthus | Your Lay Waste out-casts Baleful Strike at level 1 for a poke edge. |
| Level 2 | Karthus | At level 2 faster, cheaper Q keeps you ahead in the caster trade. |
| Level 3 | Karthus | Level 3 Q max lets you deny his stacks and win exchanges outright. |
| Levels 4-5 | Karthus | Levels 4-5 you keep the poke lead as long as you dodge his cage. |
| Level 6 | Karthus | Your instant Requiem threatens him while his R can't execute a healthy you. |
| First item | Karthus | At first item your Q burst and E shred match his spike with more safety. |
| Two+ items | Karthus | With 2+ items your range and Death Defiance passive win the 2v2 and teamfight. |
This is a mirror-style caster lane and your Lay Waste simply out-trades Baleful Strike on cast speed and mana, so poke him whenever he steps up and refuse to feed his passive by dodging his farm-Q. Freeze if you can to choke his infinite AP stacking, and never stand in a spot where his support can root you into a free Baleful. You cast faster and cheaper than he does, so contest the minions he needs to execute and his whole scaling plan slows down. Watch the mana bar as you do it. Keep Wall of Pain for the cage rather than the wave, because a slow that lands before the cage does buys you the exit.
