Magical blastbox

The Magical blastbox is a reward item from the Dungeoneering skill that can be bought with 40,000 Dungeoneering reward tokens. It was released on 19 August 2010. It requires a Magic level of 30, a Runecrafting level of 30, and a Dungeoneering level of 30 to use.

This item can store runes for use in bolt spells and blast spells. To store it the related runes must be in inventory space, and than choose charge option by right-clicking the box. The capacity of the box is indicated by "Charge". Two air and one chaos rune count to one charge in bolt mode, while three air and one death rune count as one charge in blast mode.

Once charges are put into the magic blast box, it must be wielded in order to use the runes. Using a spell will use up one charge and additional runes needed (water, earth, fire or none). The box, unlike most of other rune-supply equipments, acts according to individual spells. For any single bolt or blast spell, the full amount of chaos or death, and air runes are provided as long as a charge is available. In this way fire bolt and fire blast will have one air rune saved because two air are required to be used instead of three.

To check, empty the charges, or change mode, the box must be unequipped. If remaining charges are in the box while changing mode, the charges will automatically be returned to inventory space. Doing these without enough inventory spaces will just stop the process.
