Gunpowder

Gunpowder or blackpowder was a substance that existed across many worlds in the multiverse that was similar to the magic alchemical substance known as smokepowder.

Description
Typically gunpowder would ignite swiftly and explode, but there were a number of crystal spheres where this was not the case. And in some such worlds, gunpowder brought into them from another would be rendered inert.

Realmspace was one such sphere, owing to powerful magics cast by the deity Gond, who during the Time of Troubles revealed to his followers on Lantan the substance smokepowder as an alternative. On rare occasions Gond would allow high-ranking priests of his church to specially enchant gunpowder into a non-inert state, but never enough to threaten the dominance of smokepowder.

Creation
Much like smokepowder, charcoal, nitre, and sulfur were components of this substance.

Availability

 * High-ranking priests of Gond were willing to sell specially enchanted gunpowder, but only to those that sought to use it for the greater glory of their deity.
 * In Loudwater, the local apothecary sold gunpowder.

Beyond the Realms

 * Earth
 * Krynn was known to lack gunpowder.
 * Oerth, where the planet's local magic and physics rendered gunpowder inert.
 * Beyond the Prime Material plane, gunpowder could be found in the Domains of Dread, such as Barovia.

Usage

 * On worlds where it was not inert, gunpowder was primarily used for firearms.
 * Gunpowder wands were one of the few firearms in the Realms that operated on specially enchanted gunpowder.

Trivia
Wizards could learn how to make gunpowder from the spell Alamir's fundamental breakdown.
