The thanadaemon fixes its gaze on one creature it can see within 10 feet of it. The target must succeed on a DC 15 Wisdom saving throw against this magic or become paralyzed for 1 minute. The paralyzed target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a target's saving throw is successful or the effect ends for it, the target is immune to the thanadaemon's gaze for the next 24 hours.
