Farbane

Farbane is a magical waraxe carved from a mysterious purple crystal. This material makes it exceptionally strong against aberrations, as well as providing its wielder some protection against the same. It is currently wielded by the half-orc ranger Harthur, who found it in the Tomb of Horrors.

After slaying a powerful aberrant monstrosity that had grown out of Boccob during the Battle of Silverstone, Farbane grew more powerful by absorbing its essence.
