Ashe vs Karthus Counter Pick

Range favors Ashe by 150 units at the auto-attack level — 600 to Karthus’s 450 — yet this matchup is fought mostly with spells, and that’s where the numbers turn against her. Karthus’s kit does the work:

• Lay Waste (Q) — a delayed blast that deals extra damage to isolated targets, exactly the profile a solo laner presents.
• Wall of Pain (W) — a passable screen that cuts Move Speed and Magic Resist on anyone who walks through it, undercutting Ashe’s kiting.
• Defile (E) — Mana refunded on kills, plus a mana-fueled burn Karthus can hold around himself.

Frost Shot only slows on hit, and Ranger’s Focus needs sustained auto-attacking that Lay Waste’s poke tends to interrupt before it builds. Across 384 games on patch 16.13.1, a modest sample, Ashe wins just 42.2% against Karthus, rated Hard. Both champions carry a difficulty rating of 7, so the gap isn’t about execution — it’s a kit built for extended poke trading favorably against Ashe’s shorter effective threat range before her late-game scaling as a Marksman can take over. Karthus also ends up tankier by level 18, 2,490 health to Ashe’s 2,327, despite an almost identical starting pool of 620 to 610 — extra durability that helps him survive the poke he’s dishing out.
