Primal urn

An Infernal urn can be created at 62 Crafting (assist system can be used) with two pieces of soft clay and an air rune. It is used with the Prayer skill to help with gaining experience. The urn fills with experience the player would have earned if the ashes had been scattered instead of collected. The urn is filled when the player would have earned 1,562.5 Prayer experience with the urn in inventory. Once the infernal urn is full, it can be teleported to Ernie for 1,875 Prayer experience, which is a 20% Prayer experience bonus for all types of demonic ashes, compared to the base experience given for scattering them.

The Infernal urn essentially acts as a temporary Bonecrusher for demon-type ashes. Once ashes have been collected into the urn, they cannot be removed. The urn cannot be used with altars or the Ectofuntus.

Having an infernal urn may not be the most efficient way to train prayer. It may be one of the fastest with the inventory spaces saved. Using the Ectofunctus yields more experience per ashes, but takes more time. If a player uses 25 infernal ashes with an infernal urn, this would result in 1,875 prayer experience. If the ashes were instead used on the ectofunctus, this would instead result in 6,250 prayer experience.
