The accursed urn (full) is an item made by filling an accursed urn with accursed ashes. It can be teleported to Ernie by clicking it, giving 375 Prayerexperience. When the urn is teleported, the player gets the message, "You activate the rune on the urn and it is teleported away. You gain 375 Prayer XP."
Players can have up to ten full urns at any one time. Once that number is reached, new urns will not start collecting charges. A full urn can also be given to Ernie manually by using the item on him, or through a chat option while having a full urn in the inventory.
