Radiant energy

Radiant energy was a type of energy associated with certain good and benevolent creatures, along with those associated with the sun, the Positive Energy plane, as well as the Upper planes.

Description
Radiant energy was said to appear as a combination of "heat and light", that was either white or twinkling colors. When wielded offensively, either by means of a weapon or by magic, it both burned a target and burdened their soul with overwhelming power.

Properties
This form of energy was extremely harmful to fiends and the undead, especially shadows. It would often negate the regenerative properties of various types of undead and powerful fiends alike.
