Farming
5.5Swain
5.5Karthus

Damage
910Swain
1,457Karthus
Karthus heavily out-damages Swain by 547 DMG/min, dominating both short trades and all-in fights. Swain 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.
Economy
13,719Swain
14,510Karthus
Karthus earns 791 more gold per game than Swain, equivalent to roughly one additional component item. This economic edge comes from a combination of better farming, kill participation, and objective control, giving Karthus slightly faster item completions.
Utility
2.0Swain
0.8Karthus
Swain brings significantly more crowd control than Karthus, with 1.1 more seconds of CC per minute. This large utility gap makes Swain far more valuable in setting up jungle ganks, controlling objectives, and locking down targets in team fights.

Sustain
1,175Swain
400Karthus
Swain vastly out-sustains Karthus, healing and mitigating 775 more damage per minute. This massive durability gap means Swain can absorb significant punishment and remain in lane while Karthus is forced to recall.
