Purge of the Paragons
This bag of 100 caltrops is enchanted to explode when stepped on. Exploding caltrops look and act like ordinary caltrops, but have a small red rune carved into their sides. When stepped on, the metal spikes explode for 1d6 fire damage. There is a 50% chance that the spikes will be lodged in the victim’s foot as shrapnel, which bleeds the victim at a rate of 1 hp per turn.
