Druidic Disarm

You cause small thorny vines to form from an object a creature is holding if that object is wood. The target must make a Constitution saving throw. On a failed save, the target takes 1d4 piercing damage, and the vines ensnare and pierce the hand(s) of the creature holding the object. This ensnarement forces the creature's affected hand(s) to stay open, causing them to be unable to hold anything and disarming them. This affect lasts until the end the creature's next turn.
