You create a momentary needle of cold, sharp pain in a target creature. This causes no damage but requires the creature to make Concentration checks (DC 13) while engaged in any action that commands its full attention. On the creature’s next action following a failed check, it suddenly stands up or doubles over (DM’s choice), using a move action. There is a 50 percent chance that such a creature will drop a held item.
