Empower Familiar

You empower your familiar or summon an empowered familiar, a spirit endowed with the stat block of a CR 1 creature, at your DM's discretion. Appearing in an unoccupied space within range, the familiar has the statistics of the chosen form, though beasts summoned are celestial, fey, or fiend (your choice) instead of a beast.

Your familiar acts independently of you, but it always obeys your commands. In combat, it rolls its own initiative and acts on its own turn. A familiar can't attack, unless you forgo one of your own attacks to command the familiar to make an attack with its reaction, but it can take other actions as normal.

When the familiar drops to 0 hit points, it disappears, leaving behind no physical form. It reappears after you cast this spell again. As an action, you can temporarily dismiss the familiar to a pocket dimension. 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. 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.

While your familiar is within 100 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.

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

Finally, when you cast a spell with a range of touch, your familiar can deliver the spell as if it had cast the spell. Your familiar must be within 100 feet of you, and it must use its reaction to deliver the spell when you cast it. If the spell requires an attack roll, you use your attack modifier for the roll.

Higher Levels: For every two levels above third at which this spell is cast, you may empower your familiar to the stat block of a creature 1 CR higher. Additionally, for each two levels above third at which this spell is cast, it consumes an additional 100 gp worth of components and takes an additional hour to cast.
