Threshold

THRESHOLD is a toolkit for generating dungeons for solo TTRPG play (also works for GM-led games).  Format is a single 8.5x11" sheet of paper; trifold pamphlet design.  The mechanics are setting- and system-agnostic; just grab your favourite TTRPG system and some dice, and get rolling.

• Threshold mechanic creates suspenseful and variable encounter outcomes.
• Create dungeon architecture on the fly. [Updated 2025-04-20]
• Encounter difficulty generator
• Wandering monsters don't just show up out of nowhere.  You can hear them coming, and they can hear you too!  (And smell you, see you, etc.)
• Traps and Treasure: magical or mundane.
