A pendant would slowly change the person using it into a Berserker. Each time it was used, the pendant would slightly change the bearer both physically and mentally until the bearer desired to complete the transformation into a Berserker. During transformation the user would develop prominent veins over the skin's surface. The final form had the appearance of a man wearing animal skins. The only cure, if done early enough, was to remind the affected person who they were so that the memories would reassert their identity.
