Read from Karthus's seat: which stage windows this plan plays for against Corki.
This is Karthus's own plan; across 323 pooled games the lane is Karthus-favoured.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Karthus | You favour L1 because your Lay Waste poke matches him before his kit comes online. |
| Level 2 | Corki | Corki favours L2 because Phosphorus Bomb and Gatling poke out-trade your immobile self. |
| Level 3 | Corki | Corki favours L3 because Valkyrie mobility lets him harass and reposition freely. |
| Levels 4-5 | Karthus | You favour L4-5 because Defile flips the sustain and poke war back to you. |
| Level 6 | Karthus | You favour L6 because Requiem is a near-guaranteed pick on a squishy chunked Corki. |
| First item | Karthus | You favour first item because Defile out-sustains his poke and punishes a used Valkyrie. |
| Two+ items | Karthus | You favour 2+ items because your sustained AoE and R outscale his cooldown-reliant burst. |
Lane starts even at 1 but Corki takes 2-3: his Phosphorus Bomb poke and Valkyrie mobility out-trade your immobile early self, so farm safely with Q and dodge his all-in windows. Level one is yours to farm and level two is his to punish, so plan the mana accordingly and stop casting when the bar gets low. Never turn on Defile while he holds the shred. Wall of Pain answers his Valkyrie, so keep it in hand rather than throwing it at the wave for a faster clear.
