Bead of Force

These small, black spheres might be mistaken for common beads or perhaps unusually lusterless black pearls. As a Magic Action, you can hurl one bead to a point that you can see within 60 feet of you. Upon impact, the bead sends a bust of force in a sphere of 10-foot radius. Each creature within the sphere must make a DC 15 Strength saving throw. On a failed save, a creature takes 5d4 force damage and has the Paralyzed condition. On a successful save, a creature takes half as much damage and no other ill effects. At the end of each of its next turns, a creature can make another saving throw, ending the Paralyzed condition on itself on a success. Usually, 2d4+1 beads are found.
