Crystal horn

Crystal horn is an item used in the Princess and the Warrior. It is only obtained as a drop from a crystal dragon during and after the quest. It is used as one of the components to turn the Death altar into a Life altar. The life altar has a number next to its name, which should show how many charges the altar has until it turns back into a death altar. Every time a Life rune is crafted, one charge is consumed. One crystal horn (along with a death talisman and 100 nature-, cosmic-, exile- and astral runes) grants 100 charges to the Life altar.
