Sorcerers can come from the wild magic of the fey and have their powers uncontrolled. But those with a fey bloodline are different. They have powers related to certain fey and those powers are able to be controlled.

Sylvan Nature

You can speak, read, and write Sylvan. Additionally, whenever you make a Charisma check when interacting with fae, your proficiency bonus is doubled if it applies to the check.

You gain proficiency in the nature skill.

Natural Magic

At 1st level, Your link to the wilds allows you to learn spells from the druid class. When your Spellcasting feature lets you learn or replace a sorcerer cantrip or a sorcerer spell of 1st level or higher, you can choose the new spell from the druid spell list or the sorcerer spell list. You must otherwise obey all the restrictions for selecting the spell, and it becomes a sorcerer spell for you.

In addition, choose an affinity for the source of your natural power: Spring, Summer, Fall or Winter. You learn an additional spell based on that affinity, as shown below. It is a sorcerer spell for you, 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 druid spell list.

 

Fall

 You learn the Fog cloud 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 druid spell list.

Spring

 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 druid spell list.

Summer

You learn the Entangle 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 druid spell list.

Winter

 You learn the Sleep 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 druid spell list.

Vanishing Act

Starting at 6th level, As a reaction after receiving damage, you can spend 3 sorcery point to turn invisible and teleport to an unoccupied space you can see that is no further then 30 feet.

Butterfly Wings

At 14th level, you gain the ability to sprout a pair of buttefly 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 armor unless the armor is made to accommodate them, and clothing not made to accommodate your wings might be destroyed when you manifest them.

Archfey Presence

Beginning at 18th level, you can channel the beautiful presence of your fey ancestor, causing those around you to become awestruck or frightened. As an action, you can spend 5 sorcery points to draw on this power and exude an aura of awe or fear (your choice) to a distance of 60 feet. For 1 minute or until you lose your concentration (as if you were casting a concentration spell), each hostile creature that starts its turn in this aura must succeed on a Wisdom saving throw or be charmed (if you chose awe) or frightened (if you chose fear) until the aura ends. A creature that succeeds on this saving throw is immune to your aura for 24 hours.
