H.hhhh: (Dot delimited) At least one leading digit, and at least 4 decimal digits.(good: "0.1230", bad: ".123")
H:M: (Colon delimited) At least one hour digit, and 1 or 2 minute digits. (good: "0:1", bad: ":1" or "0:123")

How to Acquire

Cooking a River Pearl Mussel into a Boiled River Pearl Mussel, will very rarely result in a pearl in addition to a boiled mussel (a 1/100 base). (Note: Jorb has mentioned that the rate at which a pearl can be found has been reduced severely and that you should "not go looking for them, but enjoy it when you come across one")


  • A pearl's quality is equal to the uncooked mussel's quality, unmodified by cauldron, water, or cooking skill.
