Aasimar Subrace: Exosolar Lineage

Exiled, desolated, and left with no home or people; this is the birthright of those who lived in an ancient warrior society from beyond the planes. Even with their blood diluted and tainted, the intense power always remains in some form. You may not have the immense reservoir of energy that belonged to your ancestors, but you are more than able to tap into that power for a limited time.

Ability Score Increase. Your Dexterity score increases by 1.

Light's Veil. Starting at 3rd level, you can use your action to unleash the godlike energy within yourself, causing your hair to stand on end and bathe your surroundings in radiant power.

Your transformation lasts for 1 minute or until you end it as a bonus action. During it, you have a flying speed of 45 feet, and once on each of your turns, you can deal extra radiant damage to one target when you deal damage to it with an attack or a spell. The extra radiant damage equals half your level. You shed bright light in a 5-foot radius and dim light for an additional 5 feet.

While transformed, you don't need to breathe, and are immune to being charmed and frightened.

Once you use this trait, you can't use it again until you finish a long rest.
