Undead Familiar

You gain the ability to raise an creature from the dead with a CR rating of 0. Creature has the statistics they had before they died.

Your undead 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, but it can take other actions as normal.

When the familiar drops to 0 hit points, roll a d20, if you roll below 5 it turns to ash, if not it stays dead. If it stays dead you can raise it again. 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.

As an action, you can temporarily dismiss your familiar. It take on a ghostly form which cannot me seen.

You can't have more than one undead familiar at a time. If you cast this spell while you already have a familiar, the old one turns to ash.

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.
