Lock of Hair from Kirinhale

The Lock of Hair from Kirinhale can be either looted from Kirinhale's corpse or given freely to the protagonist in order to trap another - Riggilo - and in turn set Kirinhale free. There are no other known uses for this item, as it pointedly is not a Lock of Nymph's hair. It may be identified, but there is little reason to do so, other than to ascertain the description.

In-game description
"This lock of hair comes from the head of a succubus, a demonic creature that seduces men into accompanying her to the Abyss."
