I’m running Tomb of Horrors as part of my Enter the Necropolis series of Old-School Essentials one-shots. If you’ve ever wanted to try one of the most infamous D&D adventures ever written, this is your chance. You do not need to know OSE, and you do not need to make a character beforehand. I’ll have 14th-level pregenerated characters ready to go. This is old-school dungeon crawling, so expect traps, weird puzzles, hidden passages, bad decisions, and very real consequences. Fighting everything you see is probably a terrible idea. Looking at the room carefully, asking questions, testing things, and working together will matter a lot more. Character death is possible, but the goal is not to “beat” the players. I want everyone to have a good time tackling a genuinely dangerous dungeon and seeing why Tomb of Horrors has the reputation it does.
