Gravegrasp Caltrops

Rare Wondrous item
Single use

Grasped Feet. As an action, you can spread this bag of caltrops to cover a 5ft. square area. Any creature that enters the area has to make a Dexterity saving throw (DC 15). On a failed save they take 1d4 Piercing and 2d6 Necrotic damage. On a failed save, the caltrops conjure dark skeletal hands from the ground. These hands wrap around the creature and they become Restrained for up to one minute. If a creature is Restrained by these caltrops at the end of their turn, they take 2d6 Necrotic damage. A creature can use an action to free itself by making a Strength or Dexterity check (DC 15). The caltrops lose their magic and turn to ashes 48 hours after they have been scattered.
