Cinderflare Caltrops

Uncommon Wondrous Item
Single use

Singed Feet. As an action, you can spread this bag of caltrops to cover a 5ft. square area. Any creature that enters the area must make a Dexterity saving throw (DC 15). On a failed save they stop moving and take 2d6 Fire damage. Until the creature regains at least 1 hit point, its walking speed is reduced by 10ft. A creature moving through the area at half speed doesn’t need to make the saving throw. The caltrops turn to ashes 24 hours after they have been scattered.
