The Ourania Altar converts pure essence into an assortment of random runes without a chance of bonus runes being created. The altar, which requires no talisman, tiara or staff to enter, gives double the normal experience for each pure essence used. Players do not need a specific Runecrafting level in order to craft at this altar, but the chance of crafting higher-levelled runes increases with a higher Runecrafting level.
