Found in a chest in Delfran's Hideout.
A dazzling light shines from the chest, and a pair of ethereal hands rise, touch your shoulder, slides over your shoulder blade, down to your shadow. The hands move around your shadow, feeling, searching... A flash, then hands and light are gone. The chest opens.
A dazzling light shines from the chest, then shimmers, pulses... Your shadow twists into sharp shapes, shapes which stab you with searing pain.
