Read from Karthus's seat: which stage windows this plan plays for against Lucian.
This is Karthus's own plan; across 1,998 pooled games the lane is even.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Karthus | You last-hit safely with ranged Q while Lucian must enter your Defile aura to auto. |
| Level 2 | Karthus | Level 2 W slows and MR-shreds his dash, turning his short-trade window against him. |
| Level 3 | Karthus | Level 3 E Defile plus isolated Q out-pressures his Piercing Light poke. |
| Levels 4-5 | Karthus | Levels 4-5 your wave-clear and zone control snowball CS while he lacks all-in threat. |
| Level 6 | Karthus | R Requiem gives you a global execute his lifesteal can't survive. |
| First item | Karthus | First-item Defile scaling makes your AoE relentless and forces his E on cooldown. |
| Two+ items | Karthus | In 2+ item teamfights your zone and global ult outscale his single-target duel. |
Levels 1-2 you win the CS-under-tower game because Q Lay Waste last-hits from range while Lucian has to walk into E Defile aura to auto; body-block his Piercing Light on the casters and he gets no free poke. Farm entirely with Lay Waste and never walk into the range where his double-shot exists. Body-block his line on your caster minions. Defile is a trap in this lane because the mana it drains is the mana you need to keep farming, so save it for a wave you can clear from behind your own tower.
