The usual question: alternate form or change shape? Not much difference here due to lack of special abilities, but I think I'd go with change shape limited to humanoids and giants.Females have the ability to shapechange at will, assuming the form of a human or humanoid. Most prefer the shape of a comely giant or a beautiful human woman of normal sire. The female typically uses this talent to lead wanderers to their doom, as well as to attract a mate.
