Caltrops

Caltrops are metal spikes that look like large jacks, shaped so that there is always one sharp point facing up. One bag can be scattered over an area of 5 square feet. If a creature moves through or spends a round fighting in an area scattered with caltrops, there is a 2 in 6 chance it will step on one. Heavy boots reduce the chances of stepping on a caltrop to 1 in 6. Stepping on a caltrop deals 1 point of damage and reduces the creature's movement rate by half for 24 hours, or until it receives some form of healing. Stats: cost 1 gp • weight 2 lbs.
