Obtained new, the necklace comes with 10 charges. For every 10 minutes of skilling or combat, the necklace will use up one of its charges. Every time a charge is used, the player has a 25% chance of receiving a reward from the reward table. If the player doesn't win a reward, player will be rewarded with coins equal of a small cash bag. Once the necklace is depleted of all of its charges, the necklace becomes a purely cosmetic item. The 3% bonus XP is also lost when this happens. There is no way to recharge the necklace.
