Death Rune

The Death rune is used for blast spells, the highest level combat spells available in the free-to-play version of RuneScape, including Wind Blast, Water Blast, Earth Blast, and Fire Blast. Death runes are also in great demand with mages that cast Ancient Magicks, as they are used in all Ancient Magicks combat spells.

These are also the most powerful rune stocked in any store in free-to-play, and can only be crafted by members after completing Mourning's Ends Part II. Prior to the update which gave most stores in RuneScape an infinite stock of their goods and a fixed price, death runes were often bought from magic stores until they ran out of stock because there was high demand and the store price was slightly under the street price. After the update, the store price was raised above the street price.

Adult cats can be exchanged for 100 death runes with a Civilian in West Ardougne.
