Wondrous Item (vase) , Rare
The ancient Wensharians created magical vessels that could summon and contain various planer essences.
These vases could summon one potion bottle worth of essence per day, and were usually set to a specific type when created. The max capacity for a standard version of this device is 10 potion bottles worth of essence.
The essence could be removed from the vessel and transferred to a potion bottle via a siphon inserted into the top of the vase's lid.
Cracked or damaged vessels could leak or dump their contents into the surrounding area with damage or effects varying with the type of essence. I.e. fire or radiance essence could explode or burn things within the area. (damage is usually 1d6 per bottle's worth of essence).
