Phantom Bolter

Hand Crossbow, Uncommon (Requires Attunement)

An ornate redwood hand crossbow with no pull string. The metallic accents and engraving plates lead to a narrow half-tube bolt holder. When a finger is placed on the trigger, a spectral bolt appears in the half-tube, ready to be fired. This weapon requires no ammunition as it conjures its own: the spectral bolts and the weapon itself still deal piercing damage, but the weapon no longer has the loading property as it does not need to be manually loaded by the wielder.

If you make an attack roll with this weapon and hit a creature, you can choose to immediately vanish and reappear in an unoccupied space within 5 feet of the bolts impact area (no action required). You can teleport using this weapon a number of times equal to your proficiency bonus, and you regain any expended uses when you finish a long rest.
