Blood and Ice
Bag of Endless Icicles
This brown leather belt pouch produces an unlimited supply of razor ice caltrops. It takes a standard action to cover a 5 foot space in caltrops. Dumping the bag out spawns 5 pounds of caltrops per round of shaking. Anyone who moves through a caltrop planted space takes 1d4 piercing damage per round.
Popular among people who like to make a hasty exit, the bag of endless icicles also has near endless practical applications.
