Dusk Caller

 is a consumable in V Rising. It allows you to summon a swarm of bats to transport a subdued human back to the nearest unoccupied within your realm. Can only be used while is active.

If you're in a clan, it will transport the human to nearest unoccupied prison cell within all your castles. If you'd like to ensure the target is transported to a specific prison cell, make sure that cell is the only unoccupied one at the time.
