Read from Ashe's seat: which stage windows this plan plays for against Karthus.
This is Ashe's own plan; across 2,430 pooled games the lane is leaning Karthus.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Ashe | Karthus farms in your range with no escape, so your slow-and-Volley punish him early. |
| Level 2 | Ashe | At 2 he still can't dodge Frost Shot when he steps up to trade. |
| Level 3 | Ashe | Your level-3 slow keeps him from safely stacking Q procs. |
| Levels 4-5 | Even / skill | At 4-5 his Wall and Defile start to make all-ins even -- skill-dependent. |
| Level 6 | Karthus | His level-6 Requiem execute and Defile aura out-threaten you when low. |
| First item | Ashe | One-item you burst the squishy, immobile Karthus before his sustain snowballs. |
| Two+ items | Ashe | By two-plus items your permaslow, vision and R-engage make you the safer teamfight ADC. |
Bot Karthus is miserable early -- he farms in your range with no escape, so out-DPS his Q with Volley and autos and walk him down every time he steps to last-hit. He needs Lay Waste procs on your minions to keep mana up, so shove the wave and make him choose between farm and staying out of Volley range. Defile drains him fast if he tries to clear under pressure. Look for the all-in at the moment his mana drops below a full clear rather than at a fixed level.
