4. Telekinetic. If the target is a creature, it must succeed on a DC 16 Strength saving throw or the shadow moves it up to 30 feet in any direction. It is restrained by the ray’s telekinetic grip until the start of the spirit's next turn or until the spirit is incapacitated.
5. Sleep. The targeted creature must succeed on a DC 16 Wisdom saving throw or fall asleep and remain unconscious for 1 minute. The target awakens if it takes damage or another creature takes an action to wake it. This ray has no effect on constructs and undead.
