Alchemical dust

Alchemical dust is a resource that appears in Heroes of Might and Magic: Olden Era.

Alchemical dust is primarily used to upgrade artifacts and spells, but is also used for some buildings.

Rather than being obtained from a mine, dust must be created by destroying artifacts, or transferring 1 crystal, 1 gem, and 1 mercury into 5 alchemical dust at an alchemist's laboratory. It can also be found as a loose resource on the adventure map or collected from an alchemical dust storage once per week.
