If the creature does so, it can't see the gauth until the start of its next turn, when it can avert its eyes again. If the creature looks at the gauth in the meantime, it must immediately make the save.

Death Throes: When the gauth dies, the magical energy within it explodes, and each creature within 10 feet of it must make a DC 14 Dexterity saving throw, taking 13 (3d8) force damage on a failed save, or half as much damage on a successful one.

If the object is a charged item, it also loses 1d4 charges. Determine the affected item randomly, ignoring single-use items such as potions and scrolls.

2- Enervation Ray. The targeted creature must make a DC 14 Constitution saving throw, taking 18 (4d8) necrotic damage on a failed save, or half as much damage on a successful one.

3- Pushing Ray. The targeted creature must succeed on a DC 14 Strength saving throw or be pushed up to 15 feet directly away from the gauth and have its speed halved until the start of the gauth's next turn.

6- Sleep Roy. The targeted creature must succeed on a DC 14 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.
