ive been working on this one for a bit, its rarity is "artifact", it requires attunement, and the description and abilities would read:
This skull is home to a sentient air spirit of intellect, having existed for thousands of years as an assistant to generations of wizards. The spirit has an individual personality and a natural alignment of Chaotic Neutral, however it does adjust its personality to its owner and its alignment will move from Neutral to Good or Evil to match its owner's alignment. The owner must be attuned to the skull for its owner to receive any benefits.
While owning this item:
Your Intelligence score increases by 2, to a maximum of 20
You become proficient in using Alchemist's Supplies and Herbalism Kits
You gain Expertise in History and Arcana
When spending at least an hour studying or researching a topic, you have advantage on any related History or Arcana check
You can cast any spell from the Wizard spell list that has the Ritual tag up to Spell Levels you have access to. Once you use this feature, it cannot be used again until the next dawn
The skull has an armor class of 12, 5 hit points, and is immune to any non-magical damage. If its hit points is lowered to zero, the skull breaks and the spirit of intellect is released onto the world. If the spirit is released in (or ever enters) daylight, the spirit is destroyed. Otherwise, the spirit is free to move with a flying speed of 60 ft. The spirit has a strong desire to find a new home. A new home can be crafted from any humanoid skull after spending one full week and 5000 gp, representing the experiments, rituals and materials required to prepare the skull for the spirit. You can reduce the cost by 1000 gp each successive time you construct a new skull as you learn the correct procedure to prepare the skull, to a minimum cost of 1000 gp. The owner doesn’t lose their attunement to the skull due to distance or time. The skull and its owner can telepathically communicate anywhere on the same plane.
The spirit contained within the skull is able to leave the skull on occasion to perform certain tasks.
While outside of its skull, the spirit:
Cannot be seen by nonmagical means
Can communicate in any language (as it knows all languages)
Has to obey the command of its owner to the letter, though it is free to interpret those directions in any way it sees fit if the command is not clear
The spirit must return to its home in the skull by dawn. If it is not able to return (ex: the skull is on a different plane of existence, etc.) then the spirit is destroyed.
When you use this feature, you cannot use this feature or cast a Wizard ritual spell using the spirit's aid again for seven days.
