The Gold bracelet, attached to four gold finger rings by little chains, is a very powerful angreal. It was found in the Kin's Storeroom in Ebou Dar. It seems to adapt to any hand and fingers.
Since it was discovered it was usually used by Nynaeve. Only one time she lent it to Alivia to fight against the Forsaken during the Cleansing of saidin.
If Cadsuane's weak Shrike angreal enables her to reach the strength of the top male level, it can be assumed that this bracelet permits Nynaeve or Alivia to surpass a lot that level.
