Hey folks. In a couple weeks, I'm planning on running a Kobolds Ate My Baby game in the Tomb of Horrors. Yes, that Tomb of Horrors. To that end, I'm reading up on a lot of the really weird and vaguely defined stuff that you could do in old-school (i.e., pre-3.5, since that's what I'm most familiar with) D&D, since that's sure to cause some delightful havok when they're heading into one of gaming's more famous meat grinders in the name of King Torg (ALL HAIL KING TORG!).
I've dug up copies of the AD&D PHB and the 2nd ed PHB, but I don't have any of the expansions with weird spells in them. I'm reading through them, but since I'm sure I'll miss something . . . what are some of the weirder spells and effects you could find in 1st and 2nd ed D&D, ideally stuff that didn't make the transition to 3rd ed and above? Things like Sticks to Snakes or Duo-Dimension . . . you know, bizarre stuff like that. (OK, Sticks to Snakes isn't that weird, but it will be once the kobolds get their fuzzy little paws on it.) What kind of spells were there in the days when you were expected to bring a stack of character sheets to the table (I'm exaggerating, but I am reading the Tomb of Horrors)? If there are any spells that are substantially different from the modern version (you know, like Polymorph having that whole "system shock" business) in ways that would be interesting and funny in a KAMB game, I'd be interested in hearing about those too.
In short, what old-school spells and effects should I give to (and inflict upon) these hapless kobolds?
