Caltrops
Size: small

Cost: 10 ryo

Caltrops are four-pronged iron spikes designed so that one prong is pointing up
when it rests on a surface. A character scatters caltrops on the ground to injure opponents,
or at least slow them down.
One bag of twenty-five caltrops covers a single 5-foot area. Each time a creature moves
through an area containing caltrops or each round a
creature spends fighting in such an area, take 1 point of damage per turn,
and the injury reduces speed to half for 1 round. A charging or running creature must immediately stop if it steps on a caltrop.
