Bind Imp Familiar

You gain the service of a nearby and willing imp as a familiar. 

Your imp familiar acts independently of you, but it always obeys your commands, so long as they do not conflict with contracted agreements. In combat, it rolls its own initiative and acts on its own turn.

The imp can't attack, but it can take other actions as normal.

When the imp familiar drops to 0 hit points, it disappears, leaving behind no physical form. It reappears after 24 hours has passed. 

You can't have more than one familiar at a time. 

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