Your familiar acts independently of you, but it obeys your commands.

Telepathic ConnectionWhile your familiar is within 100 feet of you, you can communicate with it telepathically. Additionally, as a Bonus Action, you can see through the familiar's eyes and hear what it hears until the start of your next turn, gaining the benefits of any special senses it has.Finally, when you cast a spell with a range of touch, your familiar can deliver the touch. Your familiar must be within 100 feet of you, and it must take a Reaction to deliver the touch when you cast the spell.

Disappearance of the FamiliarWhen the familiar drops to 0 Hit Points, it disappears. It reappears after you cast this spell again. As a Magic action, you can temporarily dismiss the familiar to a pocket dimension. Alternatively, you can dismiss it forever. As a Magic action while it is temporarily dismissed, you can cause it to reappear in an unoccupied space within 30 feet of you. Whenever the familiar drops to 0 Hit Points or disappears into the pocket dimension, it leaves behind in its space anything it was wearing or carrying.

One Familiar OnlyYou can't have more than one familiar at a time. If you cast this spell while you have a familiar, you instead cause it to adopt a new eligible form.
