There have been sightings in the wild, so I can now safely post that I have them as well! Yes, I have the DungeonMorph Dice! Joe Wetzel has done an amazing job of putting these suckers together and I'm honored to have some of my designs included alongside a host of cartographic luminaries.
The dice look awesome and feel great in the hand. I've already been using them for dice games with my kids and I hope to use these real dungeon crawls at first opportunity.
