Read from Karthus's seat: which stage windows this plan plays for against Caitlyn.
This is Karthus's own plan; across 3,998 pooled games the lane is leaning Karthus.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Karthus | You favour L1 because Lay Waste lets you shove and deny her trap-and-poke rhythm. |
| Level 2 | Karthus | You favour L2 because you punish her every time she enters auto range to CS. |
| Level 3 | Karthus | You favour L3 because W and Defile give kill threat she can't kite through. |
| Levels 4-5 | Karthus | You favour L4-5 because sustained Q poke keeps her low with your support enabling all-ins. |
| Level 6 | Karthus | You favour L6 because Requiem punishes a range-reliant Caitlyn who over-extends. |
| First item | Karthus | You favour first item because Defile plus support CC closes her range for a burst kill. |
| Two+ items | Karthus | You favour 2+ items because your teamfight AoE zoning denies the angles her kit depends on. |
You handle Caitlyn's range at 1-2 by shoving with Lay Waste and denying her the trap-and-headshot setup; punish every time she steps into auto range to last-hit and space behind your minions. Shove with Lay Waste and the trap-and-headshot setup never assembles, because a wave crashing under her tower is a wave she cannot zone you off. Watch your mana while you do it. Keep the wall for the moment her net is spent, so the follow-up from her support has to walk through a slow.
