Radiant Aura works on all enemy types
Radiant Aura is a great QoL skill, but it currently only damages Fell foes. Since it deals fire damage (which most enemies are susceptible to), it would be nice if it could affect all enemies
My suggestion:
Add a skill node that expands Radiant Aura's damage to all enemies, not just Fell. This would make radiant aura more versatile and satisfying to use and won't make it overpowered because the new skill might cost quite a lot of skill points.
