Amulet of Leadership

Leadership. (Recharges after a long rest). For 30 seconds, the Wearer can utter a special command of warning whenever a nonhostile creature that it can see within 30 feet of it makes an attack roll or a saving throw. The creature can add a d4 to its roll provided it can hear and understand the wearer. A creature can benefit from only one Leadership die at a time. This effect ends if the wearer is incapacitated.
