Classic Modules Today: The Ruins of Undermountain (5e)

In 1991, TSR published the boxed-set named "The Ruins of Undermountain," with the product code "TSR 1060." It was written by Ed Greenwood, the mastermind behind the Forgotten Realms campaign setting. "Ruins" consisted of a 128 page campaign guide, with 32 pages of adventures and adventure hooks set in Undermountain. In addition to an extensive sandbox-style dungeon complex, the module provided guidance on expanding and creating additional levels and encounters for adventures in Undermountain. The boxed-set was very well-received, and it was ranked as the 17th best Dungeons and Dragons adventure by Dragon Magazine in 2004.

This conversion guide allows DMs to run the original module with 5th Edition rules and provides a reference sheet for encounters.

To use this conversion guide, you will need a copy of "The Ruins of Undermountain", originally available in hard copy and now for sale in digital format at DMsGuild.com.

"Classic Modules Today: B4 The Lost City" contains the OpenOffice/LibreOffice source files used to create the PDF. Visit Classicmodulestoday.com for instructions on creating your own classic module conversions and selling them on the DMs Guild.

What this Conversion Is, and What it Is Not: 

This conversion is for the original module, as it was written. Classic Modules Today conversions are designed to convert the magic items, monsters, traps, and other key statistics from the original module into 5th edition. These guides set the adventure in the Forgotten Realms, and may offer some additional notes on running the adventure, or suggestions for extra encounters, but they are primarily conversions that are faithful to the original module. 

Per guidelines from One Book Shelf and Wizards of the Coast, we are not permitted to revise or reinvent these adventures; we may only convert the above elements over to their corresponding 5th Edition counterparts.
