I could not find a topic on this, so I'm posting here

Regarding spells like Banish and Scourge (where damage is split amongst elements), do CON spells that lower elemental resistances (i.e. Burn, Rasp, etc.) actually increase damage from these spells? Or are they lumped into an entirely separate category when this is calculated (i.e. 'Umbral', rather than 'Ice', 'Earth', 'Water')?
