The Acid Gun is a weapon crafted by tinkers. The acid is contained in specially treated wax pellets that serve as bullets. When fired, the heat from the gunpowder melts the wax and expels the acid in a wide spray. The acid gun sprays acid in a 10-foot-long cone.
After people began getting acid burns after firing the weapon, tinkers decided that such a ridiculously dangerous weapon should be made safer by being sold with safety gloves. So with every acid gun, the buyer receives free a pair of thick gloves, and must sign an affidavit saying he does not blame the creator if he fires the gun and gets acid on his hands.
