// There isn't any obvious way to combine different values but it currently can't happen:
// - More than one source damage source for ApplyModifiersToSkillDamage can't happen because
// With(DamageSource) only takes one argument.
// - Different ApplyModifiersToAilmentDamage values for different source damage sources don't make sense.
// If e.g. crit multi for spells and attacks would be applied to ailments at different values, it would
// be ambiguous how to apply generic crit multi, which is split into the damage sources, to ailments.
// - The current solution would not work if different stats of the original StatBuilderResult (built from
// the core builder) have different ApplyModifiersTo values. That is possible with IDamageStatBuilder and
// its damage types, but damage-type specific ApplyModifiersTo modifiers do not exist.
