This is Caitlyn's own plan; across 3,998 pooled games the lane is leaning Karthus.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Caitlyn | Your range and headshot passive crush short-range Karthus at level 1. |
| Level 2 | Caitlyn | At level 2 his mana-limited Lay Waste can't win the trade against your poke. |
| Level 3 | Caitlyn | Q and traps zone his farm and starve his mana in lane. |
| Levels 4-5 | Caitlyn | Through 4-5 you out-shove and dive his immobile, no-escape frame. |
| Level 6 | Caitlyn | Requiem can't win the 2v2 as you Net and burst him first. |
| First item | Caitlyn | Your first-item tempo out-pokes and out-pushes his scaling curve. |
| Two+ items | Caitlyn | Late, kiting outside Lay Waste and bursting his fragile frame beats his scaling if you end quickly. |
You dominate early Karthus: he has short range, no mobility, and burns mana on Lay Waste, so your 650 range and headshot passive win every trade and last-hit at level 1-2. Walk him down and deny his farm start. He needs Lay Waste procs to keep his mana up, so shoving the wave costs him the poke as well as the farm. Stay off the small circle, take your last-hits from the outside, and step in the moment his mana drops. Defile is his only answer to a walk-up, and it drains him faster than it drains you.
