Create Skelital Familiar

You bind a lost soul to a skull, creating a floating skull that serves you. The floating skull appears in an unoccupied space within range.
The skull acts independently of you, but it always obeys your commands. In combat, it rolls its own initiative and acts on its own turn.
While the skull is within 100 feet of you, you can communicate with it telepathically.
When the skull drops to 0 hit points, it is destroyed and turns into a pile of dust, and nothing short of the wish spell can bring the soul bound to the skull back to life.
You can have up to three floating skulls bound to you with this spell. If you create another floating skull after that with this spell, a skull chosen by the DM is destroyed and turns into a pile of dust.

At Higher Levels. When you cast this spell using certain higher-level spell slots, you can create more floating skulls; two floating skulls with a 3rd-level slot and three floating skulls with a 5th-level slot. You must prepare separate material components for each skull created this way. The skull may not attack during combat but otherwise can take any other action
