The Fae are born being able to shift into an animal shape, this being each Fae has two forms, their Fae form and their animal form. This is based on them having magic stores left and if you use up your magic while in one form you are unable to shift into the other until you have restored some of your magic. This will be based on your proficiency bonus and your magic spell slots.

During Character creation you will choose what type of magic you want your Fae to be proficient in. you can choose any type of element, or raw magic which can take any shape of magic. Raw magic is rare and you will need to write into your backstory how your character inherited raw magic. Magic type is passed down through family so some of your characters family will need to be able to use the magic type you choose for your character.
