Druids, Shaman, and Clerics:
Created a new spell effect for Celestial Healing, Celestial Elixir, and Torpor. This will allow them to stack with all other spells, save spells of the same type (Heal over time). Prior to this, all heal-over-time spells followed the same rules as regeneration spells.

I could be wrong; throwing this out there for the great classic gods.
