Level 7: Fey Fun
Level 11: Fey Companion, Truesight
Level 15: Fey Step
Starting at 7th level, you gain access to a number of illusion spells that the fey creatures use on mortal to have some fun. Each spell counts as a Ranger spell for you, but it doesn't count against the number of Ranger Spells you know.
You know and have prepared the following spells: Color Spray, Disguise Self, Illusory Script, Invisibility, Magic Mouth, Nystul's Magic Aura, Hypnotic Pattern.
Starting at 11th level, you can cast Find Familiar without components, but you can cast it only as a ritual. Your familiar can have any form you want, but it still needs to respect the given stat blocks of the spell.
Starting at 11th level, as an action, you can gain Truesight until the end of your turn.
Starting at 15th level, as an action, you can partially move through the Feywild until the beginning of your next turn. While in this state, you are partially insubstantial, can move through solid objects and have resistance to non-magical damage. If you end your turn inside a solid object, you will be automatically pushed back to your point of entry and suffer 4d6 force damage.
