Read from Aphelios's seat: which stage windows this plan plays for against Karthus.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Karthus | Karthus's Q and Defile poke bully the weak level-1 Aphelios. |
| Level 2 | Karthus | At level 2 his Lay Waste and drain keep him firmly ahead. |
| Level 3 | Karthus | Level 3 his poke out-trades your single-gun output. |
| Levels 4-5 | Karthus | Through levels 4-5 his Q and Defile continue to dominate. |
| Level 6 | Karthus | Level 6 Requiem and Wall zone your positioning entirely. |
| First item | Karthus | At one item his AP scaling out-damages your gun swaps. |
| Two+ items | Aphelios | With two-plus items your DPS finally out-scales his frame. |
Karthus owns levels 1-2 with Q Lay Waste last-hitting and poking you while Defile chips your health; hug max range, dodge his Q casts, and accept a farm deficit rather than trading into his poke. Lay Waste has no cooldown but it does have a mana cost, and the longer you make him clear the wave, the shorter his poke gets. Take the minions you can reach without standing still, hold Severum for the chip, and leave Defile range entirely once he turns it on. Your window opens when his mana can no longer pay for a full clear.
