Karna damage range = [[(1089+11976)*1.05*4*1.5*1.3*0.9*0.23*1.2]+200] to [[(1089+11976)*1.05*4*1.5*1.3*1.1*0.23*1.2]+200] = 26779 to 32686 damage to each target
So from this it looks like the Mordred rolled ~1.0x on her random modifiers while your Karna rolled really high (~1.1x) on his random modifiers.
