I carry around a little pocket notebook most days. It's useful in general, but over the past few months, since I started working on my Megadungeon, I've been using it most during my commutes to and from work to jot down ideas for special or interesting encounters, traps, monster combinations, or generally odd things I'd like to throw in the Megadungeon.
That little notebook is now full, and I have a new one. So I decided to copy all of those Specials into a document here on the computer to print out and have easy access to when I get back to stocking the dungeon. And of course, why not share? These are just idea prompts, not every encounter will be just like this when I stock them, so if by chance anyone who plays in my Megadungeon has read them, they won't necessarily be at an advantage. Feel free to use, modify, or mock them as you please (I fully admit some of these are stolen, and some are very cheesy).
