Dungeon Master Builder is a dungeon editor for the PC version of Dungeon Master and Dungeon Master 2 developed by Sphenx. It has many features not found in any other tool, like the ability to create dungeons with up to 63 levels, choose the number and types of creatures and ornates on each level, create an arbitrary number of objects (doors, items, teleporters), and more!
Version 0.88.g2 adds experimental support to read Theron’s Quest dungeons and more documentation.
This tool was previously known as “DMEdit”.
You can report bugs and make suggestions on the Dungeon Master Forums.
Note that this tool can only load dungeon files with a checksum.




Beowuuf posted the following table to the forum for use with DMBuilder to get wall triggers to work. Set the trigger to ‘activate by item’, scroll to the object referenced, then change the wall object back to ’trigger’. The list of combinations for activation extends beyond this for all possible combinations (for example there is an ‘activated by open on all face’, etc to make a total of sixteen sets).
