Lock of Nymph's Hair

Lock of Nymph's hair has no use, but it can be sold to the owner of Sorcerous Sundries for 500 gold coins or you can trade it in combination with 100 gold for a Nymph's cloak. It can also be sold to other merchants, but only for 250 gold. It is gained when you help the nymph Abela from the claws of one of the two rivalling mages.

In-game description
"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."
