Turn Familiar

You perform a 24-hour long ritual to turn a willing creature into your familiar, you can only do this to a creature who's Challenge Rating is no more than 3. That creature is then bonded with you and has its own small pocket dimension of your own design.

While your familiar is within 150 feet of you, you can communicate with it telepathically. Additionally, as an action, you can see through your familiar's eyes and hear what it hears until the start of your next turn, gaining the benefits of any special senses that the familiar has. During this time, you are deaf and blind with regard to your own senses

Your familiar acts independently of you, but it always obeys your commands. In combat, it acts directly after you in the initiative order, and can only attack if you spend your bonus action commanding your familiar. Otherwise, it can take other actions normally.

When the familiar drops to 0 hit points, it returns to its pocket dimension, leaving behind no physical form. It returns after you cast the spell again.

As an action, you can temporarily dismiss your familiar. It disappears into a pocket dimension where it awaits your summons. Alternatively, you can dismiss it forever. As an action, while it is temporarily dismissed, you can cause it to reappear in any unoccupied space within 30 feet of you.

You can't have more than one familiar at a time. If you cast this spell while you already have a familiar, the spell fails.
