Call of the Wild

You gain the companionship of a beast of no more than CR½ that you have encountered including, but are not limited to, hawk, eagle, owl, raven, black bear, boar, deer, panther, wolf,  bat, poisonous snake, and weasel. A Druid of 11th level of greater may gain the companionship of a Beast up to CR1.

Your companion animal acts independently of you, but it always obeys your commands. In combat, it rolls its own initiative and acts on its own turn. A companion can't attack, but it can take other actions as normal.

The animal companion remains with the Druid until death or until it is released or another companion is called.

While your companion is within 100 feet of you, you can communicate with it telepathically. Additionally, as an action, you can see through your companions's eyes and hear what it hears until the start of your next turn, gaining the benefits of any special senses that the companion has. During this time, you are deaf and blind with regard to your own senses.

As an action, you can temporarily dismiss your companion. It will retreat nearby where it awaits your call. Alternatively, you can release 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 before the next turn.

You can't have more than one companion at a time. If you cast this spell while you already have a companion, your current companion will be released into the wild.

Finally, when you cast a spell with a range of touch, your companion can deliver the spell as if it had cast the spell. Your companion 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.
