Bind Familiar

You bind a creature of large or smaller size to your service as a familiar. The creature must be non-hostile to you and within the range of the spell for the full casting time or the spell fails. The creature's challenge rating must be 1/4th of your current level (rounded down) or lower when you cast this spell, otherwise the spell has no effect. Through binding a creature to you with this spell, it becomes celestial, fey, or fiend (your choice) instead of its normal creature type and its alignment changes to match yours. Additionally, the gem that is used to cast this spell becomes a vessel for your familiar which you can, as an action, use to house the creature in, and summon the creature from.

Your familiar acts independently of you, but it always obeys your commands. This familiar can make any action that is available to it normally. In combat, it acts immediately after your initiative.

When the familiar is below 0 hit points and is within 120 feet of you, it automatically disappears and retreats to its vessel, leaving behind no physical form. The creature is stabilized while within its vessel but makes death saves as normal outside of it.

While your familiar is within 120 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.

While your familiar is above 0 Hit Points, you can temporarily dismiss it as an action. It disappears and retreats to its vessel where it awaits your summons. As an action while it is within its vessel, you can cause it to reappear in any unoccupied space within 30 feet of you.

You can't have more than one familiar at a time. If you cast this spell while you already have a familiar you must chose to release your current one first or the spell fails.

If the challenge rating of the creature would change for any reason while it is bound to you, the creature remains in your service.

This spell ends if the creature dies, if you die, if the gem is destroyed or if you release the creature from your service.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, you reduce the casting time by half for each slot level above 5th.
