The Lock of Nymph's Hair can be sold to the owner of Sorcerous Sundries for 500, or can be fashioned into a Nymph Cloak by him for 100. It can also be sold to other merchants, but only for 250 . It is gained when you help the nymph Abela out of the claws of one of the two rivalling mages in Baldur's Gate. This item appears in Baldur's Gate and Baldur's Gate: Enhanced Edition.
Sometimes in BG:EE, Abela gives the PC a Nymph Cloak with 0 charges instead of the lock.
|“||While nymph's hair has no magical properties of its own, it is an important component in a variety of charisma-related spells spells and items, not the least of which is the fabled Nymph's Cloak.||”|
