Phantom Bolter

Hand Crossbow, Rare (Requires Attunement)

An ornate blue mahoewood hand crossbow with no pull string or loading mechanism. The metallic plates that secure a narrow half-tube at the top are finely cut with a slight downward slope leading to the firing vent. When a finger is placed on the trigger, a spectral bolt appears in the half-tube if the wielder is attuned to the weapon. 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. Once a spectral bolt hits its mark, or misses, it vanishes.

This hand crossbow is especially effective at hindering an undead creature of ghostly or spiritual nature. When struck by a bolt, it remains embedded in the creature instead of vanishing: the bolt prevents the creature from turning invisible, teleporting, or possessing another creature. The bolt remains in the creature until it is killed, until you choose to let it vanish (no action required), or until the creature ends its turn at least 60 feet away from the hand crossbow.

As an action, you can turn this weapon invisible. This invisibility ends if you use the weapon to make an attack or harm something, if it is no longer on your person or being wielded by you, or if you use another action to end it early.
