Tazir's Greater Familiar

You bind a fey or fiendish spirit to serve as your familiar. The creature retains it's type, but takes the form of a beast of your choice. It uses the statistics of the chosen form.

The chosen form must have a challenge rating no greater than 1, and can not be of a size larger than medium.

Your familiar acts independently of you, but it always obeys your commands while it is under your control. In combat, it rolls its own initiative and acts on its own turn. You must use your bonus action to command your familiar to attack, but it can take other actions as normal. If the chosen form has the ability to attack more than once using it's action, it can only attack once when you command it. If you issue no commands, it defends itself to the best of it's ability.

When the familiar drops to 0 hit points, it disappears, leaving behind no physical form, leaving behind in its space anything it was wearing or carrying.

While the familiar is under your control, you can use your action to temporarily dismiss it to a pocket dimension inside the gem used in the casting, along with any items it's wearing or carrying. While it's in the pocket dimension, you can use your action to cause it to reappear in any unoccupied space within 30 feet of you.

While you are in control of your familiar, and you are on the same plane of existence, you can communicate with it telepathically. Additionally, as an action, you can project your mind into your familiar, taking complete control of it. During this time, your body is unconscious. You return to your body if you loose control of your familiar, it drops to 0 hit points, or use an action to withdraw you mind.

If the gem used in the casting of this spell is ever removed from your person, dispelled, or otherwise destroyed, you loose control of your familiar. When you loose control in this way, the familiar is free to act of it's own volition, and it may become hostile towards you, depending on its nature and how you've treated it. It may also choose to return to it's home plane as an action. If you cast this spell while you already have a familiar, the gem used in the previous casting magically shatters.

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.

At higher levels. If you cast this spell with a spellslot of 5th level or higher, the maximum challenge rating of the chosen form increases to 3, and the maximum size increases to large. Using a spellslot of 7th level or higher increases the challenge rating to 5, and the size to huge. Using a spellslot of 9th level, the challenge rating increases to 10, and the size restriction is removed.
