Barbed Wire

This motorized spool of razor-sharp barbed wire can be deployed to cover a small area in loops that will bring pain to whatever poor soul tries to rush through it. Over the course of a minute, you can spread a spool of barbed wire to cover a 10-foot-square area, which becomes difficult terrain. When a creature moves into or within the area, it takes 1d4 piercing damage for every 5 feet it travels. The barbed wire takes 10 minutes to wrap back into a spool.

Notes: Damage: Piercing
