Palace - New Faction

Excellent!
However, there is no Plane of Fire in the Asylum; instead, the Elemental Planes are replaced by Elemental Dragons.

But I haven't seen any statements anywhere that it doesn't exist. In the pantheon of D&D worlds, there are also gods responsible for the elements. At the same time, the Planes serve as their home!

I like it. It's a good idea. And how much mana does level 4 have?

Presumably, Mystics and Fanatics have around 12. And Astrologers have 16.
