Royal Fey

However recent or distant, you have a bloodline tied to Fey royalty, which has awakened in you a magical power and connection with the Feywild. Some claim to have awakened such power through ritual blood sacrifice of a fey creature, but most such sorcerers powers appear to be lineage-based. Nevertheless, 'common' fey like, respect or fear you and the royal power you effortlessly manifest. 

Fey

You can speak, read, and write Sylvan. Additionally, whenever you make a Charisma check while interacting with fey, your proficiency bonus is doubled if it applies to the check. Beasts always react to your presence as if under the Animal Friendship spell. As a bonus action you unfurl tiny insectoid wings which sprout from between layers of clothing or armor, granting you a flying speed of 15 feet and can hover in place. If you already have a flying speed, it increases by 15 feet. 

Fey Royalty

Beginning at 6th level, the magic of your royal bloodline causes fey creatures (who are normally resistant or immune to enchantments) to be susceptible to your enchantments. Your insect wings grow stronger, increasing your flying speed by 10 feet. 

Ascendant Fey

At 14th level you have begun to manifest the resistances of the greater fey, shrugging off the mundane harms of the mortal world and lesser wielders of magic. You gain resistance to nonmagical bludgeoning, piercing, slashing damage. You also have advantage on saving throws against spells and magical effects.

Irresistible Enchantment

As the powerful royal lineage manifests, at 18th level your enchantment spells become so potent hardly anyone can resist them. The spell save DC for Enchantment spells you cast equals your Charisma score plus your proficiency modifier.
