Fiora normally has a slightly larger longest kill spree than her enemy does. Commonly, Fiora takes more damage than Karthus. This often reflects differing health capacities, but it can also indicate that the one champ has less agility and thus is unable to kite away from further damage when engaged or poked.

Fiora commonly racks up many more minion kills than Karthus. Champions that do not amass much CS usually do not have to have much CS to be effective. Instead, they are capable of scaling adequately off their abilities alone. Yet, champs with large amounts of CS, such as ADCs, usually have to have a lot of items to be effective.
