Old modules with Random effects

I'm looking for old TSR-modules with random elements. And with "random" I mean quite extraordinary effects, like you sacrifice a living heart on an altar and maybe all your abilities rise a step or you die (something like the effects in Deck of Many Things).

In new OSR-modules these effects are quite common, but I'm looking for original modules for ODD/BDnD/ADnD with these effects.

As an example: Steading of the Hill Giant Chief & Hall of the Fire Giant King both have weird temples where very strange things can happen.

X2 (Castle Amber) has a number of these. A magical dinner. One course will raise your hit points, one will raise one ability 1-2 points and lower another 1-2 (randomly), one will make you either need no food or twice as much food, or give you a +4 bonus vs point or kill you.

It also had a deck of cards type deal, and a magic square thing. One of those things where the letters spell the same words in a different directions? If you walk across a certain path it does so and such to you.

EX1 (Dungeonland) has a magical grotto with a d20 for effects. All are temporary. It's also got a magical hat table where the Mad Hatter tosses one at a PC at random.

B1 has a wonderful room of pools. Some of the pools are magical and drinking from them can have various effects.

B1 has some as EW mentioned.

UK1 has one at the very beginning.
