An APC artillery duel — bounce angles against his cadence; the satchel referees the dives both ways.
Track: Karthus's R — Requiem (200–160s cooldown). The global execute — recall above the red line and track it from his level 6 on.
Read from Ziggs's seat: which stage windows this plan plays for against Karthus.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Ziggs | Level 1 favours Ziggs because Q out-ranges his walk-up Lay Waste and he has no mobility to close. |
| Level 2 | Ziggs | Level 2 stays yours as he must step into your poke to farm. |
| Level 3 | Ziggs | Level 3 is Ziggs's with the range to chunk him off every CS attempt. |
| Levels 4-5 | Ziggs | Levels 4-5 remain yours since he still lacks the tools to trade back through your poke. |
| Level 6 | Karthus | Level 6 flips to Karthus: Requiem globally executes you after any exchange and Defile sustains his trades. |
| First item | Karthus | At first item Karthus's Liandry's-fed Q, Defile aura, and R finishing keep the window his. |
| Two+ items | Ziggs | With 2+ items Ziggs swings back as your burst and range out-pace his ramping Defile. |
Levels 1-4 are yours: Karthus has to walk into range to farm with Lay Waste and has zero mobility, so your longer Q simply out-pokes him. Chunk him every time he steps for a CS, keep minions between you and his poke, and starve him of the free stacking that fuels his mid-game. He has to walk into range to farm and cannot leave, so out-distance him, bomb the wave and chip his walk-ups. Stay outside the Defile ring while you do it. Keep the minefield for the beat after his wall, and take the plate rather than diving a champion who dies usefully.
