This is probably the best Shadowdark gauntlet published so far. It took our party of 5 about 4 hours to run. Deadly, but felt fair. Great puzzles. It really helps establish the resource management aspects of SD in a way that was engaging to the party.
Drop Mugdulblub’s name a few times as the party is pushed into the first chamber and again if they get out and you have a perfect intro to the Gloaming setting from Cursed Scroll 1.
