Wow, I should say, WOW! this thing is impressive! feels great in hand, really allows a GM to hang up the GM screen and play some games with their playgroup. random dungeon, generator. mix this with trap dice and monster dice, you have a dungeon system in a bag or case. I love the huge size, I bought some D20s of equal size (edit-were actually larger), and this will go along greatly! Added picture.

It’s so chonky and a very unique dice idea, really cool concept, happy to add it to my collection. Painting is a little rough tbh but still really cool

This is now the crown jewel of my weird dice collection. It's massive, the casting is perfect, the paint flawless, and it's fun to generate a cave with it. Genuinely wish I could give this more stars somehow.
