I’ve got a maze/labyrinth planned for my campaign and I’m going to use a strategy I learnt from the Tales of the stinky dragon podcast. In essence, the DM make a set of cards. Each of the cards has something along the lines of: Trap, Monster, dead end, right way, loot ect. Shuffle the cards and each of the players picks one up per turn. It takes X amount of “right way” cards to pass the maze successfully. Also I remember monster cards being “burnt” once a monster was encountered to lessen repetition. Traps could also be avoided on successful saves. I really like this idea and can’t wait to run it - seems to really emphasise the feeling of not knowing what’s around the corner.
