Caltrops, bag of 50
Cost: 5 cp
Weight: 2
Small spiked objects used to hinder movement and slow down pursuers.
As an action, you can spread a bag of caltrops to cover a square area that is 5 feet on a side.
Any creature that enters the area must succeed on a DC 15 Dexterity saving throw or stop moving this turn and take 1 piercing damage.
Taking this damage reduces the creature’s walking speed by 10 feet until the creature regains at least 1 hit point.
A creature moving through the area at half speed doesn’t need to make the save.
