Changes

Barbed caltrops are like regular caltrops but with a few exceptions, these caltrops were made to cause pain and bleeding . If the barbed caltrops succeed on the attack, the creature has stepped on one. The barbed caltrop deals 1 point of damage, then causes 1 bleed damage a round for 1 minute or until a dc 20 heal check is done or the application of healing magic.  Removing the caltrop causes 1d3 damage unless a DC 20 heal check is done. Also the creature’s speed is reduced by one-half because its foot is wounded.  This movement penalty lasts for 48 hours, or until the creature is successfully treated with a DC 25 Heal check, or until it receives at least 3 points of magical curing. A charging or running creature must immediately stop if it steps on a barbed caltrop. Any creature moving at half speed or slower can pick its way through a bed of barbed caltrops with no trouble.
