In this episode, I look at the Son of Kyuss from the Fiend Folio, one of the nastiest undead in AD&D. This is not just a monster fight. It is fear, disease, worms, panic, and long-term trouble for any party that gets careless. I talk about why it works so well at the table, how to use it in a dungeon, and why monsters like this are a big part of what makes AD&D feel dangerous.
