Burning Head

You set your head on fire. Your head is consumed by flames of any color of your choice and your flesh burns away until only your skull remains. You have resistance to fire damage until the start of your next turn. On your next turn you must use your action to remove your head, otherwise the spell fails. Your head counts as a tiny creature with an armor class of 10 + your dexterity modifier, a number of hit points equal to your level times 3, and immunity to fire damage. Your head gains a flying speed that is also equal to your spell-casting ability times 3. On each turn afterwards you can make your head move up to its movement speed (no action required) and you can use a bonus action to make a ranged spell attack with a range of 10 feet originating from the head. The attack deals (1d8) fire damage plus your spell-casting ability modifier. You continue to see out of your head even as the head moves. You can use your action to make your body do any of its normal actions, however you make attack rolls and ability checks using strength or dexterity with disadvantage. If your head and your body are within 5 ft of each other you can reconnect your head and body using either an action or bonus action ending the spell

If your head is reduced to 0 hit points the spell ends. If your body is reduced to 0 hit points the spell ends and you are knocked unconscious. If the distance between your head and your body exceeds 120 ft. the spell ends. If the spell ends and your body and head are not connected your head disintegrates and your suffer from the paralyzed condition for one round while your head grows back.
