Your soul shares part of an angelic soul. You may be an Aasimar, and this is a common source of power for Aasimar Sorcerors, but characters of any race may have a touch of angel in them.

Angelic Magic

Your angelic nature allows you to learn spells from the cleric class. When your Spellcasting feature lets you learn or replace a sorcerer spell or cantrip, you can choose the new spell from either the cleric spell list or the sorcerer spell list, and it becomes a sorcerer spell for you.

In addition, choose an affinity for the source of your angelic power: good, law, chaos, or neutrality. You learn a spell based on that affinity, shown below. It is a sorcerer spell for you, and it doesn’t count against your number of sorcerer spells known. If you later replace this spell, you must replace it with a spell from the cleric spell list.

Chaos

You learn the bane spell, but it doesn’t count against your number of sorcerer spells known. If you later replace this spell, you must replace it with a spell from the cleric spell list.

Good

You learn the cure wounds spell, but it doesn’t count against your number of sorcerer spells known. If you later replace this spell, you must replace it with a spell from the cleric spell list.

Law

You learn the bless spell, but it doesn’t count against your number of sorcerer spells known. If you later replace this spell, you must replace it with a spell from the cleric spell list.

Neutrality

You learn the protection from evil and good spell, but it doesn’t count against your number of sorcerer spells known. If you later replace this spell, you must replace it with a spell from the cleric spell list.

Angelic Grace

Starting at 1st level, your angelic grace guards your destiny. If you fail a saving throw or miss with an attack roll, you can roll 2d4 and add it to the total, possibly changing the outcome. Once you use this feature, you can’t use it again until you finish a short or long rest.

Angelic Knowledge

Your angelic nature grants you the ability to retain knowledge of magic beyond that of most mortals, allowing you to learn spells above and beyond those granted by the Sorcerer class , at the DM's discretion, from books, scrolls, or from other sources. These spells become Sorcerer spells for you, use spell slots to cast if they are not Cantrips, and do not count against your total number of spells known.

Angelic Portent

Starting at 6nd level your angelic nature grants you glimpses of the future in your dreams or while you rest. When you finish a long rest, roll two d20s and record the numbers rolled. You can replace any attack roll, saving throw, or ability check made by you or a creature that you can see with one of these foretelling rolls. You must choose to do so before the roll, and you can replace a roll in this way only once per turn. Each foretelling roll can be used only once.

When you finish a long rest, you lose any unused foretelling rolls.

Angel Wings

Starting at 14th level, you can use a bonus action to manifest a pair of spectral angel wings from your back. While the wings are present, you have a flying speed of 30 feet. The wings last until you’re incapacitated, you die, or you dismiss them as a bonus action.

The affinity you chose for your Angelic Magic feature determines the appearance of the spectral angel wings: white wings for good or law, brown wings for neutrality, and black wings for chaos.

Angelic Recovery

At 18th level, your angelic soul grants you the ability to overcome grievous injuries. As a bonus action when you have fewer than half of your hit points remaining, you can regain a number of hit points equal to half your hit point maximum.

Once you use this feature, you can’t use it again until you finish a long rest.
