Damage
775Viktor
990Karthus
Karthus heavily out-damages Viktor by 214 DMG/min, dominating both short trades and all-in fights. Viktor should avoid extended combat and instead focus on burst trade patterns — short engages followed by immediate disengagement — to avoid letting Karthus's sustained damage advantage take over.

Healing
