Damage
1,238Karthus
665Sylas
Karthus heavily out-damages Sylas by 572 DMG/min, dominating both short trades and all-in fights. Sylas 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.

Both Karthus and Sylas provide similar amounts of crowd control (0.1s/min difference), meaning neither has a significant advantage in locking down opponents for ganks or team fights. Lane ganks are equally effective for both sides.
Sustain
