Karthus vs Evelynn Counter Pick

Evelynn carries a difficulty rating of 10 and Karthus a 7, yet the 186 games logged on patch 16.13.1 hand her the matchup and leave him at 41.9%. The mechanism is Demon Shade. Out of combat she heals when low and gains Camouflage from level 6, so she chooses when contact happens and Karthus never has the information his kit requires. Placing delayed blasts where an enemy will be stops working against an opponent who is not on screen until the moment of the strike.

Allure compounds it, charming the target and cutting magic resistance before Whiplash and Last Caress arrive — a full burst into 620 base health, 21 base armor and 30 magic resistance. The counterplay reads well on paper: Wall of Pain slows and shreds magic resistance across a wide screen, Defile punishes anyone standing close, and Evelynn fights at 125 units against his 450. Death Defied denies her a clean execution as well, since the spirit form keeps casting and Requiem still resolves after he dies. In practice, control wards on camp entrances are worth more than any item decision, because the whole problem is information rather than statistics — at 2,308 health and 116.9 armor by level 18 she is not built to survive a fight she did not start.
