Wondrous Item, very rare
This small, round sphere looks normal from the outside but is helpful in events of paralysis and containment. This gray and jade ball is able to contain up to eight large humanoids or the equivalent mass. Within the ball, creatures may be kept comfortable in the event of sudden paralysis and for easy of transporting. The ball may be activated once per short rest. To encase someone in the ball, you must touch them with the object. To recall them, the ball must be tossed on the ground, in which case, all of the ball's contents will re-emerge in the existing space. The inside of the ball acts like Lemond's Tiny Hut in that it is impenetrable, comfortable, and roomy.
