Damage Gained as extra X

Damage gained as a specific damage type only scales with modifiers to the new type, not with modifiers to the source damage's type (unless they're the same type). For example, Lightning damage gained from Physical damage scales with Lightning damage modifiers, but not Physical damage modifiers. Damage Gain occurs in the same two step process as Damage Conversion. Damage over time cannot benefit from damage Gain.
