Maybe its just because heroes of horror just came out (though I thought it sucked) but horror in D&D has really seemed like fun to me recently. the magic abilities of some creatures and what not make for some seriously bad-ass set-ups, as well as some of the monster's, especially int eh MM II & III. which rule by the way.
So the question is, what were the best horror game scenario's in D&D or otherwise you guys have had? or, what are ideas you can come up with?
So far, I've got a two story haunted house scenario using an Allip with the spell-stitched template, modified to use illusion spells instead. its looking pretty nice.
WHat do you guys got?
