The impious urn (unf) can be made using the Crafting skill. Players with a crafting level of 2 can make an Impious urn by using 2 soft clay on a potter's wheel, granting 12 crafting experience. Firing it in a pottery oven will give 20 crafting experience and turn it into an impious urn (nr). An air rune must be used on it to make it active.
