Aasimar (Fernian)

You have Resistance to Fire damage and Necrotic damage.

You have Darkvision with a range of 60 feet.

As a Magic action, you touch a creature and roll a number of d4s equal to your Proficiency Bonus. The creature regains a number of Hit Points equal to the total rolled. Once you use this trait, you can't use it again until you finish a Long Rest.

You know the Produce Flame cantrip. Intelligence, Wisdom, or Charisma is your spellcasting ability for this spell (choose the ability when you select this species).

When you reach character level 3, you can transform as a Bonus Action using one of the options below (choose the option each time you transform). The transformation lasts for 1 minute or until you end it (no action required). Once you transform, you can't do so again until you finish a Long Rest.

Once on each of your turns before the transformation ends, you can deal extra damage to one target when you deal damage to it with an attack or a spell. The extra damage equals your Proficiency Bonus, and the extra damage's type is either Necrotic for Necrotic Shroud or Radiant for Heavenly Wings and Inner Radiance.

Here are the transformation options:
