The metal dodecahedron had twelve sides, each of which was painted with a number 1 through 12. Overall, it measured 12" (30.5 cm) across. Clockwork machinery composed its inner workings, which whirled and clicked whenever the die was cast.
Depending on the side that faced up whenever the die was thrown, one of six possible effects occurred:
- 1, 2: The dodecahedron burst in an explosion and was completely destroyed.
- 3, 4: A light spell was cast upon the die, which remained until it was touched by any creature.
- 5, 6: A ray of frost shot out from the die towards a random person or creature.
- 7, 8: The next creature to touch the dodecahedron was hit by a shocking grasp.
- 9, 10: A darkness spell was cast upon the die, lasting for 10 minutes.
- 11, 12: The next creature to touch the die became significantly more resilient for an hour's time.
- ↑ Canon material does not provide a year for the events described in Waterdeep: Dragon Heist, but Christopher Perkins answered a question via Twitter and stated the year was 1492 DR. Unless a canon source contradicts this assertion, this wiki will use 1492 DR for events related to this sourcebook and Waterdeep: Dungeon of the Mad Mage (which is referenced on pages 5 and 98 of Dragon Heist).
