Properties

• These matched hoops are linked. When an object (up to a maximum of 15 pounds) is placed in one hoop, roll a d20. On a result of 2–20, the object placed in the hoop disappears and reappears in the other hoop instantly, regardless of the distance between them, as long as both hoops are on the same plane.
  
• Malfunction: On a result of 1 on the d20 roll, any creature adjacent to either hoop takes 10 force damage.
