Fey Friendship

Befriending a Fey usually comes with a myriad of gifts. In your case, befriending a minor fey has given you the following:

Ability Score Increase: Increase your Intelligence, Wisdom, or Charisma score by 1, to a maximum of 20.

Friendly Spellcasting: You learn how to cast Find Familiar, Speak with Animals, and Animal Friendship, and always have those spells prepared. You can cast each of these spells without expending a spell slot. Once you cast any of these spells in this way, you can't cast that spell in this way again until you finish a Long Rest. You can also cast these spell using spell slots you have of the appropriate level. The spells' spellcasting ability is the ability increased by this feat. The Familiar created by your Find Familiar spell must take on the Fey creature type.

Fey Aid: When your familiar takes the help action, they can create and administer one berry from the spell Goodberry to a willing or unconscious creature, as part of that help action. Your familiar can do this a number of times equal to half of your proficiency bonus, refreshing on a long rest.
