Dust Runes are a rune from Runescapes that combines the effects of two of the four elemental runes into one item. They may be used in place of both elements for any spell, even spells that utilize both Air and Earth Runes.
Dust Runecrafting requirements
For you to create your own Dust Runes, you will need to have at least level 10 Runecrafting. Every Dust Runecrafting expedition you take will require Pure Essence, at a rate of one piece of essence for every Dust Rune crafted. The other items required for the process will vary depending on the Runecrafting altar you visit.
If you wish to visit the Air Altar south of Varrocks Cooking Guild, youll need a stack of normal Earth Runes equal to the amount of Dust Runes you intend to craft, as well as an Earth Talisman and a means to get into the Air Altar. Both will work for this purpose.
The Earth Altar near Varrocks eastern lumber yard is equally accessible, although the elements of all items are reversed. Youll rather bring Air Runes along with a disposable Air Talisman or Earth Tiara for access to the altar. As with both altars, wearing an elemental tiara will save inventory space and allow you to bring another piece of pure essence per inventory.
Runecrafting Dust Runes
To get to the Air or Earth altars, you must either climb their respective ruins in the overworld and place the same-element talisman on it, or, if wearing the elemental tiara, left clicking it. This will take you directly to the actual altar, which you may manipulate to create runes.
The way you interact with the altar will affect the type of runes you craft. Left-clicking on the essence in your inventory will only produce runes of that type, which will result in the creation of Air or Earth Runes instead of the desired Dust Runes. Instead, using the other stack of elemental runes on the altar Air Runes on the Earth Altar or Earth Runes on the Air Altar will fuse dust runes at the cost of both the disposable talisman and the
Making combination runes has a 50% success rate, meaning that around half of your available essence will be crafted into Dust Runes per trip. If done correctly, making use of relevant teleports, Abyssal Titan summons, full essence pouches, and Binding Necklaces can turn a profit of around 20,000,000 GP hourly, making Dust Runecrafting one of Runescapes' most profitable money-makers.
