Fistful of Lead: Custom Dungeon Builder Card Deck. Book III of our Fantasy Trilogy has a perfectly good dungeon builder chart you can use with a regular deck of cards, OR your Fistful of Lead deck. However, we thought you might like these nifty custom cards. No need to check the book, because the dungeon features are cleverly printed on the cards. If you are a fan of dungeon crawls, this is the way to build it.
