I'm designing a dungeon for the first time using the wip #Cairn2e Dungeon Seeds procedure.
You roll 6 to 20 d6 on a page and each number rolled is a room type (monster, lore, trap, special) with their own 2d20 spark tables, then you lay paths that can be direct, hidden or conditional.
I rolled a special room with wheel / locks in one of the central rooms, I'm thinking about a wheel you turn to rotate the walls and open and close paths, feels very Zelda.
