Beholderkin - Gauth (CR 5)

The  Gauth is one of those monsters that most of us have fought in video games, but which I never really hear getting used in day to day tabletop. I think this is a shame, as they represent a nice bit of Eye Tyrant weirdness at a much lower level. For this conversion I went to 2nd Edition AD&D, and pretty much recreated the same thing. I did tweak the explosion however, as in the original there was only a 2% chance of this happening...which seems pointless.

Anyway, here it is...

If they roll a natural 1 on this saving throw, the item is permanently drained of all magic. For 1 minute following the successful removal of magic from an item, the Gauth glows brightly, as if it had been affected by a Faerie Fire spell.


Final Eruption: When reduced to 0 hit points, the Gauth begins to glow brightly, casting bright light in a 60' radius. At the end of its next turn, it explodes in a 60' sphere, inflicting 8d10 force damage to all within – half if they make a D.C. 15 Constitution save.
