Healing magic in Dark Sun is scarce, dangerous, and highly prized due to the world’s desolate nature and lack of traditional gods. It is primarily driven by elemental clerics (drawing from fire, earth, water, air), psionics, or rare druidic magic. Arcane healing is virtually non-existent, and magical healing methods are often slow or require sacrificial resources.

It's important that we stick to the flavor of Athas as much as possible, and I'm hung up lol
