Starting at 3rd level, you can use your action to unleash the divine energy within yourself. The instant you transform, other creatures within 10 feet of you that can see you must each succeed on a Strength saving throw (DC 8 + your proficiency bonus + your Charisma modifier) or become restrained by you until the end of your next turn.

Your transformation lasts for 1 minute or until you end it as a bonus action. During it, 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 your level.

Your Charisma score increases by 2.

Aasimar mature at the same rate as humans, but they can live up to 160 years.

Imbued with celestial power, most aasimar are good. Outcast aasimar are most often neutral or even evil.

Aasimar have the same range of height and weight as humans.

Your base walking speed is 30 feet.

Blessed with a radiant soul, your vision can easily cut through darkness. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern color in darkness, only shades of gray.

You have resistance to necrotic damage and radiant damage.

As an action, you can touch a creature and cause it to regain a number of hit points equal to your level. Once you use this trait, you can’t use it again until you finish a long rest.

You know the druidcraft cantrip. Charisma is your spellcasting ability for it.

You can speak, read, and write Common and Celestial.
