Karthus vs Varus Counter Pick

The 58.6% belongs to Karthus, though it rests on 111 games from patch 16.13.1 — the kind of sample that moves several points in a quiet week. The direction matches the kits. Varus is rated 2 for difficulty and plays a straightforward distance game at 575 units against 450, opening with a charged Piercing Arrow that gains range and damage the longer he holds it. That pattern works against champions who have to walk forward; Karthus does not walk forward, and Lay Waste pays extra against whichever target has stepped away from company.

Defensively Varus is exposed. He finishes at 92 armor and 2,385 health at level 18, and armor is irrelevant against a magic-damage kit in the first place, so his usual defensive shopping does not address the actual threat. Blighted Quiver adds magic damage to his attacks and detonates on his abilities, which pushes him toward extended trades — precisely what Defile is built to punish — while Hail of Arrows slows and cuts healing rather than creating separation. Chain of Corruption is the genuine danger, immobilising the first champion it hits and spreading onward. Even then, Death Defied keeps Karthus casting after death, and a three-second Requiem finishes an enemy who committed to the kill.
