Weapon (hand crossbow), uncommon (requires attunement)

This hand crossbow is the result of an experiment gone wrong. While the goal was to enchant it so that it would multiply the bolts fired from it, it ended up only multiplying the head of the bolt. En masse.

The weapon has 6 charges that recharge each day at dawn. As a bonus action, you can expend one charge to fire a bolt from it at a point on the ground within 30 feet of you. When the bolt hits, it covers a 5-feet-square area with bolt heads. Any creature that enters the area must succeed on a DC 13 Dexterity saving throw or stop moving and take 1 piercing damage. Until the creature regains at least 1 hit point, its walking speed is reduced by 10 feet. A creature moving through the area at half speed doesn't need to make the saving throw.
