VAULTS - A D66 Dungeon Supplement and Card Set

VAULTS is a dungeon and indoor-exploration supplement for Game Masters. Roll 2d6 and you have a ready-to-run space: what the party sees when they arrive, the detail that reveals what it actually is, and a danger that gives the room teeth. No stats, no prep, works with any fantasy TTRPG.

A room is never just a room. Not down here.

How the D66 Works

Roll 2d6. The first die picks the category. The second die picks the space. VAULTS includes two complete D66 tables: 12 options per category, 72 location entries total.

• Vestibules — Entrances, antechambers, the room before the room
• Architecture — Room features, furnishings, what a space was built for
• Uncharted — Branching paths, dead ends, the unmapped unknown
• Lairs — Throne rooms, ritual sanctums, set-piece chambers
• Tunnels — Corridors, stairwells, chokepoints, the spaces between
• Secrets — Hidden doors, concealed rooms, what was meant to stay buried

Every Space Has Three Layers

• The Description — What the space looks and feels like the moment the party arrives. Read-aloud ready.
• The Detail — What the space actually is, was built for, or is hiding. GM-only info.
• The Danger — The sting that keeps it from being a flat description. A threat, but just as often a cost, a choice, a time pressure, or a revelation.

The Danger is a dial. Play it as an active threat, or treat it as atmosphere and foreshadowing. Every entry gives you one. Using it as written is always optional.

The gap between what a space looks like and what it actually is drives every entry. A room reveals itself in stages: first impression, then closer understanding, then consequence. Some spaces are exactly what they seem, right up until they aren't.

[IMAGE] Phase 1 ladder + Delver tease: Locked-ladder graphic like TAVERN's "Meet the Bartenders" scroll, plus 2 Delver portrait samples to tease the art.

Not every dungeon is empty. As funding grows, illustrated Delver NPCs are added to the supplement: fellow explorers, trapped survivors, long-dwelling hermits, imprisoned scholars. Each has a portrait, a personality, and something practical to offer the party, whether it's knowledge of the layout, a safe route, a warning about what lies ahead, a key, or supplies.

• $200 — +2 Delver NPCs
• $400 — +2 (4 total)
• $600 — +2 (6 total)
