Carl's bulk crafting supply, thrown by the sackful to coat and reveal an invisible attacker.
Carl carries a dozen sacks of Gunpowder in his inventory, each bag the size of a pillowcase. Cornered at the settlement gate with his Protective Shell about to drop and no idea where his invisible attacker is, he drops the guard's spear, pulls a sack, and throws it.
The sack spins through the air spilling black powder, hits something solid, and the powder forms a shape around the creature. It hisses over his head and shakes most of the dust off, but enough clings that when Princess Donut's Magic Missile lands, Tootsie's fur pops and sparkles as the powder cooks off, dropping her invisibility and half her health.
Black powder carried in pillowcase-sized sacks.
Carl's improvised anti-invisibility weapon and bomb-making staple.
