Darkness, Ring of Power application to magick/DoT

Not sure if this was a bug or intentional, but neither Darkness nor Ring of Power affects magick damage, including from magick ammunition. Since magick and especially the damage/time from magick ammunition are generally weak and most enchantments don't stack it would be great if:

• Darkness and Ring both affect magick ammunition damage/time, and

• Darkness and Ring both affect magick damage

The inability to have enchantments active while casting others beyond Ring of Power and Summon Swarm makes it a slow-burn build even when maxed with the best materials and T4 infusions, and vs the bosses even worse because of their mechanics and immunities (Sheliak's immunity to all but weakpoint damage), so making Darkness persist through other enchantments on top of it affecting enchantments would be a big deal.
