Dungeon of the Three Fools - Multi-Die Dungeon Creation Tables
Originally, we played Dungeons and Dragons (from the three books in the little white box, in fact). Then we advanced to Dave Hargrave's Arduin Grimoire. During all that time, of course, we used and collected all those multi-colored dice in their profusion of sides. From the pointy little four-siders to the zocchihedron (a 100 sided die named for Lou Zocchi, whom I had the pleasure to meet once), we used and collected (what role player doesn't collect dice, eh?) them all. As a consequence, my first dungeon creation tables freely switched back and forth across all those differenct dice.
These tables date from about 1978. We still use them, whenever we are in the mood for a mindless dungeon romp.
Note: The tables shown here are fairly (but not totally) faithful to the original tables. I improved some of the wording and added a Type of Trap table (to be parallel to the D6 tables).
Need tables that print more nicely? Here's a Word version.
