Miss Fortune vs Karthus Counter Pick

This is a losing matchup for Miss Fortune and a small one to measure: 213 games on patch 16.13.1 returning 44.6%. Karthus in the bottom lane trades an ordinary marksman duel for an attrition problem, since he attacks from 450 units against her 550 but almost none of his damage requires him to use that range.

The specific pressure points:

• Lay Waste is a delayed blast dealing increased damage to isolated enemies, and a marksman farming behind the wave is frequently isolated.
• Defile surrounds him in a persistent aura, so proximity costs health continuously instead of in discrete trades.
• Wall of Pain reduces movement speed and magic resist together, against a champion starting on 30 magic resist with no dash.
• Death Defied lets him keep casting after dying, removing much of the reward for winning an all-in.

Strut is the one structural counter she owns, granting passive movement speed while she avoids damage and activating for attack speed when she commits. Karthus builds his lead slowly from 46 base attack damage, 620 health and 21 armour, so an early Bullet Time aimed into a stationary channel is the realistic win condition, taken before Requiem starts converting his farm into damage delivered to every enemy champion at once. Past that window, holding a healthy position instead of contesting every wave is the compromise most games settle into. Kits: Miss Fortune, Karthus.
