Gunpowder

Cost: 1sp = Ounce

Gunpowder is a black, granular, alchemical mixture of sulfur, charcoal, and saltpeter, giving the substance its more common name of “black powder.” It is a necessary ingredient in bombs and in the paper cartridges used by firearms. Igniting an ounce of gunpowder causes it to burn for 1 round, shedding bright light in a 20-foot radius and dim light for an additional 20 feet. Gunpowder in larger quantities can have more devastating effects. When used as a weapon or explosive device, gunpowder has the gunpowder weapon property.

• Barrel (125 gp). A barrel contains enough gunpowder to fill approximately 40 gunpowder horns. Igniting a full barrel of gunpowder causes it to explode at the end of the next round. Each creature within 15 feet of the keg must make a DC 12 Dexterity saving throw, taking 2d4 piercing plus 5d6 fire damage on a failed save, or half as much damage on a successful one.

• Horn (3 gp). A horn contains enough gunpowder to create 30 paper cartridges. Igniting a full horn of gunpowder causes it to explode immediately. Each creature within 5 feet of the horn must make a DC 12 Dexterity saving throw, taking 2d6 fire damage on a failed save, or half as much damage on a successful one.

• Keg (65 gp). A keg contains enough gunpowder to fill approximately 20 gunpowder horns. Igniting a full keg of gunpowder causes it to explode at the end of the next round. Each creature within 10 feet of the keg must make a DC 12 Dexterity saving throw, taking 1d4 piercing plus 3d6 fire damage on a failed save, or half as much damage on a successful one.
