Most often, sorcerers with this origin had a mighty sorceress ancestor of the favored soul or who was favored by the god they prayed to. Some of these bloodlines are well established in the world, but most are obscure. Any given sorcerer could be the first of a new bloodline, as a result of a pact or some other exceptional circumstance. No matter the circumstance you slowly reveal the angel within you.

Heaven's Gifts

Starting at 1st level the heavens shine upon you. The heavens grant you enhanced durability. Your hit point maximum increases by 1, and it increases by 1 again whenever you gain a level in this class.

When you aren’t wearing armor, your AC equals 13 + your Dexterity modifier. 

You can read, write, and speak Celestial.

Divine Magic

At 1st level your ancestor grants you his divine magic. Your link to the divine allows you to learn spells normally associated with the cleric class. When your Spellcasting feature lets you learn a sorcerer cantrip or a sorcerer spell of 1st level or higher, you can choose the new spell from the cleric spell list, in addition to the sorcerer spell list. You must otherwise obey all the restrictions for selecting the spell, and it becomes a sorcerer spell for you.

Angelic Weapons

At 6th level you gain proficiency with one martial weapon of your choice.

The angels grant you weapon skills. Your weapon becomes imbued with your angelic essence. When you hit a creature you may deal an additional 1d8 radiant damage. You may use this feature three times per long rest.

While you hold this weapon, you can choose to make it shed bright light in a 20-foot radius and dim light for an additional 20 feet.

Angelic Might

At 14th level the angel within you slowly reveals itself and you glow a bright light around you. You become immune to disease and poison damage, and resistant to radiant and necrotic damage. You gain a +2 to your AC while not wearing armor.

Sound the Trumpets

At 18th level the angel within you fully reveals itself you gain the ability to sprout a pair of angel wings from your back, gaining a flying speed equal to your current speed. You can create these wings as a bonus action on your turn. They last until you dismiss them as a bonus action on your turn.

You can’t manifest your wings while wearing clothing not made to accommodate them or your wings might damage the clothing.

You are now immune to radiant damage.

When you cast a spell of 5th level or lower, you draw on the surrounding magic infused in the universe to aid your casting. Roll a d20 and subtract your spellcasting ability modifier, if the result is less than 0, you do not expend a spell slot for casting that spell. You can only use this once for each school of magic between long rests. If you roll is equal to a 0 or a 1, you can use a spell slot that is 1 level higher than the spell slot you are attempting to use, however, you must have that spell slot in order to gain this benefit.
