Familiar

A familiar is a creature that is bound to a magic user such as a wizard or warlock by magic. It can take on the form of an animal or another small creature, and it obeys their commands. Familiars are very helpful companions, and they can help with a variety of tasks. For example, a wizard's familiar can scout ahead for them or deliver messages. A Pact of the Chain warlock can even summon more vicious or aggresive familiars which will attack their enemies.
