Months ago, my D&D campaign headed in the direction of going through the WotC 4E Tomb of Horrors. They puzzled over the traps and obstacles set before them, started thinking laterally (at least a little) and were having a good time. The culmination of the Garden of Graves, the end encounter, loomed before them. They were ready to tackle this and, in fact, very eager. They had just spent the last few sessions perplexed by the mysteries of the adventure, but at the same time had their eye on the map of the complex provided so early on in the Garden. They knew the end was coming, and they were dying to know just what the hell had been going on. Despite this adventure being a cut above the rest of WotC's stuff, I knew that I needed to crank it up to deliver the kind of awesome experience they were looking for.
I had to kill a god.
