Empty canopic jar (Dimension of Disaster)

The empty canopic jar is used in Dimension of Disaster/Curse of Arrav. It's given to you by Ernie after you fill up a strong cooking urn for him.

You are supposed to turn this into a prepared canopic jar by adding sacred oil, dwellberries and a ring of life to the jar in any order.
 * Adding dwellberries creates a canopic jar with berries
 * Adding a ring of life creates a canopic jar with ring
 * Adding sacred oil creates a canopic jar with oil
