Homebrew
Celestial Resistance. You have resistance to radiant damage.
Light Magic. When you reach 3rd level, you can cast the Faerie Fire spell once. Once you reach 5th level, you can also cast the Moonbeam spell once. You must finish a long rest to cast these spells again with this trait. Wisdom is your spellcasting ability for these spells.
Radiant Halo. Three glowing orbs float above your head, passively orbiting to form a halo-like ring. Each orb sheds dim light in a 10-foot radius. As a bonus action on your turn, you can move an orb up to 30 feet to a point within 60 feet of you. If an orb is ever more than 60 feet away from you, it winks out of existence and reappears above your head.
