You summon tiny celestial, fey, or fiend servant (your choice when you cast the spell), using the familiar template (below) to serve you until it is reduced to 0 hit points. You can't have more than one familiar at a time. If you cast this spell while you already have a familiar, you instead grant it the ability to adopt a new form. Choose one of the forms from the above list. Your familiar transforms into the chosen creature.

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 you can see 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 deafened and blinded with regard to your own senses.

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.

Your familiar gains a special shapechange ability from this list below (chosen when you summon the familiar). As an action, your familiar can change its shape to resemble that of a tiny animal. The familiar gains one of the following bonuses when it uses an action to changes into a tiny animal :

• Shapechange: Amphibious Form. The familiar takes the form of a tiny amphibious animal (such as a frog, salamander, or turtle). While shapechanged, the familiar gains a 25 feet swim speed and can breathe water as well as air.

• Shapechange: Climbing Beast. The familiar takes the form of a tiny climbing animal (such as a lizard, monkey, or squirrel). While shapechanged, the familiar gains a 25 feet climb speed and adds your proficiency bonus to Dexterity saving throws.

• Shapechange: Digging Beast. The familiar takes the form of a tiny digging animal (such as an armadillo, meerkat, or mole). While shapechanged, the familiar gains a 5 feet burrow speed.

• Shapechange: Land Beast. The familiar takes the form of a tiny land animal (such as a cat, mouse, or weasel). While shapechanged, the familiar gains a 40 feet speed (instead of 25).

• Shapechange: Flying Beast. The familiar takes the form of a tiny flying animal (such as a bat, bird, or butterfly). While shapechanged, the familiar gains a 25 feet fly speed.

• Shapechange: Swimming Beast. The familiar takes the form of a tiny swimming animal (such as a fish, jellyfish, or squid). While shapechanged, the familiar gains a 40 feet swim speed, looses its regular speed, and can breathe water instead of air.
