Generating a random dungeon in DW with Tarot

This reddit post suggests you can draw tarot cards to make a dungeon, but doesn't provide much in the way of guidelines to finish it off. In Dungeon World, it could be fair to assume the same thing about dungeons that you do about treasure. That they are related to the damage dice of the enemy. Damage dice in dungeon world are very small. I don't recall seeing anything bigger than (b[2d12+9] damage). The average dungeon befitting a boss monster with just such damage would be 6.5+9 or 15.5. Call it 16 since it's the better of two rolls, which are presumed an average of 6-7. Another example, the bandit king (b[2d10]), would be probably about a 6 room dungeon. You can toy with it too. Goblins might not have half the damage roll in dungeon rooms, and a Noble who has a Knight probably has twice the Knight's damage roll of rooms in his castle.
