DemonCracker

Typical Cost: 350 yen - black market only

This flash-bang grenade looks like a typical ninja trick, but its powder is infused with the ground-up essence of a demon lord, and if the target who is struck by it fails a save versus death magic, they are transported to one of the 666 planes of the Abyss. They will arrive somewhere nominally "safe," but making it back home to the Prime Material is far from guaranteed, and likely to take 10 to 30 days (presuming one isn't killed or captured...) A successful to hit roll (ignoring armor) is required for this item to work.
