• If the target is a creature, it must succeed on a DC 14 Strength saving throw, or the zombie moves it up to 30 feet in any direction. It is restrained by the ray's telekinetic grip until the start of the zombie's next turn or until the zombie is incapacitated. If the target is an object weighing 300 pounds or less that isn't being worn or carried, it is moved up to 30 feet in any direction. The zombie can also exert fine control on objects with this ray, such as manipulating a simple tool or opening a door or container.
