Dust rune

Dust runes are combination runes. They count as two separate runes: one earth rune and one air rune. Thus, any spell requiring one earth rune, one air rune or both will spend only one dust rune.

They can be created with the Runecrafting skill or purchased with Pizazz points from the Mage Training Arena.

The Dust battlestaff offers unlimited amount of Dust runes.

Runecrafting Dust runes[]

At Runecrafting level 10 or higher, they can be crafted in either of two ways:

Pure essence, earth runes and an earth talisman to the Air altar (for 8.3 Runecrafting experience per rune)
Pure essence, air runes and an air talisman to the Earth altar. (for 9.0 Runecrafting experience per rune)

Tiaras will not work in place of talismans while crafting combination runes. Combinations have a 50% success rate (or 100%, if the player is wearing a binding necklace), and the talisman is consumed in the process (unless the player uses the Lunar spell Magic Imbue).

Note: Binding Dust Runes will consume the secondary talisman, for example: Using an air talisman at the Earth altar will consume the air talisman.
