One of my favorite items in Castle of the Winds is the distillation of water, a useless potion. You can drink them though, just like any other potion. It's just so absurd. I used to collect them in a chest as I played, just for fun.

I toyed around with suggesting just finding one and drinking it for a misc category, but that's too quick. They're pretty common, especially in Part 1, and it might be a bit more interesting to watch if there was more to it than getting lucky on the first level of the mines.

My idea would be finding 5 Distillations, then drinking them all, in either part 1 or part 2. The one rule is, they have to be identified BEFORE you drink, as it adds the need to identify somehow, and prevents people from just grabbing every potion they find and chugging them. That would be harder to verify, and probably a little less fun to watch.

Part 1 has more of a chance to drop them, but part 2 has the identify spell and the detect items spell available from the beginning both of which you can utilize to find them. Heck because map level scrolls reveal all items, refreshing levels that way might be the easiest way to find them in part 2.

I'm going to try a demo of it some time this week and I'll post it here, but let me know if it sounds interesting! With all the weirdness in this game, I bet there's at least another misc category that could be thought up...
