BUC

BUC is an acronym meaning Blessed, Uncursed, Cursed. It is usually used in phrases such as "BUC identified", meaning an item whose "BUC status" is known.

For some items, such as gold pieces or scrolls of mail, the BUC-status has no meaning and is always omitted. For some other items, such as armor or rings without charges, it is not shown if you have fully identified the item. Also, priests never see the uncursed-status.
