Black pearl

The black pearl is a reward from the quest A Shadow over Ashdale, where three are rewarded. When cracked, they will give bonus experience in a skill of your choice. The experience given is dependent on that skill's level. For the quest reward pearls, it is equivalent to a large fallen star in the skill chosen; for the rewards from the repeatable boss to a medium fallen star. Unlike most experience-related rewards, the black pearls from the quest are bankable. Only one quest black pearl can be used per day; attempting to use a second pearl gives the message: "You must wait until tomorrow before you can use another black pearl."

NOTE: although the pearls grant bonus experience to any player, only members can use bonus experience.

Following the quest, the dead man's chest in the Ashdale Caves can be accessed to fight the final battle against Agoroth again, giving a black pearl with bonus experience in any skill equal to that of a medium fallen star. This can be done once per week, or twice per week for members. Both of the week's pearls may be cracked on the same day. Black pearls obtained after the quest can also be converted to coins.

Black pearls earned after the quest are not bankable. In addition, black pearls earned after the quest may be used alongside other black pearls earned before the quest for additional bonus experience.

Trivia

 * The item name may be a reference to the Pirates Of The Caribbean film series; a ship named Black Pearl appears throughout the franchise.
