-6 delvers (Warrior, Wizard, Elf, Dwarf, Thief, and Priestess.)All you need is a 3D printer. So if you've got one--or you're handy with that hacker/maker stuff-- then you've got yourself an endlessly printable dungeon!
-10 dwellers (2 Skittering Fiends, 2 Restless Spirits, 2 Hogboglins, 2 Shambling Corpses, 1 Cave Gronk, and 1 Ancient Guardian)
-40 dungeon tiles (print the tile set twice)
-6 door markers
-13 counters (6 Treasure counters, 6 Hazard counters, and 1 Stairs counter)
-12 six-sided dice (6 red Offense dice and 6 blue Defense dice) (These weren't printed, though I suppose you could)
Check out the full set-up. Props to Boing Boing for finding this little treasure.
