What's in Descent into the Lost Caverns of Tsojcanth?

Artist: ZOLTAN BOROS

Iggwilv, the Witch Queen, was a powerful entity known for her magical mastery, cunning, and propensity to ally with demons to further her goals. The Lost Caverns of Tsojcanth were once her lair, but Iggwilv has not been heard from in decades.

As is fitting for the former lair of a dangerously magical individual, these caverns are said to be brimming with treasure, magical artifacts, and danger.

Descent into the Lost Caverns of Tsojcanth is a remastered version of the iconic, first-edition dungeon crawl, The Lost Caverns of Tsojconth, a tournament adventure written by Gary Gygax, the co-founder of D&D.

This updated adventure is suitable for 9th-level characters and can be completed in a single three- to four-hour session. The appendices contain exclusive magical items that the party will receive if they successfully navigate the dungeon, a new stat block for the pech, six premade characters with D&D Beyond and downloadable PDF character sheets, and optional tournament scoring rules.

The expanded version of this adventure, Lost Caverns of Tsojcanth, has been updated for the fifth edition as well and appears in the upcoming adventure collection, Quests from the Infinite Staircase, releasing July 16!

How Does Tournament Scoring Work?

The tournament scoring rules included with this adventure are meant to add a fun twist to your games. These rules are optional, you don't need to use them to run the adventure. If you're playing at a convention or a local game store, they can be used to determine the highest-performing party to win prizes. If you're using these rules during your home game, they are simply a means for bragging rights.

Dungeon Masters can use the provided scoring system to track the party's progress, with points being added or subtracted based on the party's actions.

The adventure operates within a strict four-hour time limit, so characters must make quick decisions and be strategic in battles. Additionally, to maintain the challenge, characters are limited to one short rest throughout the session and cannot take long rests.
