Fflar's Scabbard is used to upgrade Foebane. This item appears in Baldur's Gate II: Throne of Bhaal and Baldur's Gate II: Enhanced Edition.
It is found in a locked chest in the just west of the prison cells on second level of the Saradush prison. The chest can be found in one of the northwest rooms.
|“||This scabbard is the companion to Fflar's enchanted blade Foebane, and like the sword was rumored to have been lost when Myth Drannor fell.||”|
