Moonchild

You draw your power from the moon. Maybe you're a descendant of one of the sorcerer-kings or sorceress-queens of Maelari. Maybe you were gifted this power by a moon deity such as Gariseph or Selûne. No matter where you came from, your power is unquestionable with your control of moonlight and even being able to take on a form of pure moonlight for a time.

Moonlit Eyes

Starting at 1st level, your eyes glow with moonlight. If you don't already have darkvision, you gain 60 feet of darkvision. If you already have darkvision, your darkvision range increases by 30 feet. You are also immune to the blinded condition. You also learn the sacred flame spell, which does not count against your spells known and counts as a sorcerer spell for you. (update darkvision yourself.)

Lunar Power

Starting at 1st level, you can empower your spells with moonlight. When you fail a spell attack roll or a creature succeeds on a save against one of your spells, you can add 1d4 to the spell save DC temporarily or the attack roll. You can do this a number of times equal to your Charisma modifier (minimum 1). You regain all expended uses upon completing a long rest. (keep track of it yourself, I can't figure out how to do it, sorry.)

Enhanced Moonlight

Starting at 6th level, you gain resistance to radiant damage.

You also can spend 2 sorcery points to change a damaging spell you cast so its damage type becomes radiant. When you use your lunar power on a spell that deals radiant damage, you can add 2d4 instead of 1d4.

Moonlit Step

Starting at 14th level, you can use your bonus action to disappear in a flash of moonlight, reappearing in a location 30 feet away from you that you can see.

Moonchild Transformation

Starting at 18th level, you can spend 6 sorcery points to transform into a being of pure light for up to 1 minute. You can dismiss this form as a bonus action. This form grants you the following benefits:

• You gain a flying speed of 30 feet.
• You give off bright light for 30 feet and dim light for an additional 30 feet.
• A creature within 60 feet of you takes a step down on their defenses against radiant damage (i.e. normal >> vulnerable, resistant >> normal, immune >> resistant).
• You can use your action to cast moonbeam. Once you do so, you cannot cast it again until 1 minute has passed.
