Some dungeons are bigger than others! Flip-Tiles: Dungeon Vaults Expansion is the newest expansion to the Flip-Tiles: Dungeon Starter Set. With 24 full-color 6 x 6-inch double-sided tiles, each stunningly crafted by cartographer Jason A. Engle, you can add even larger fanes, occult chambers, arcane workshops, and strangely shaped chambers to your dungeon.
