Edit Shadow Key. A shadow key is an item found in gold chests in the dungeon. Shadow keys are required for unlocking a shadow chest. All shadow chests are originally found locked. Unlike a golden key, shadow keys are not consumed when unlocking a chest.
Muscle twitching, also known as muscle fasciculation, is marked by small muscle contractions in the body. Your muscles are composed of fibers, tissues, and nerves. When a nerve is stimulated or damaged, it may cause your muscle fibers to twitch. Many twitches experienced in your body are common and may go unnoticed.
Involuntary contractions or muscle twitches of the biceps can be alarming. Although muscle twitches are often harmless, they can be a sign of a serious underlying disorder. People with persistent biceps muscle twitching should see a doctor to determine the cause of the twitching and rule out a neurological disorder.
