Here's a thing I'm playtesting for Lunchtime Dungeons.
(Click the pic.)
The exploration procedure has been working pretty smoothly for a few months now, but I was inspired by a peek Luka Rejec gave us of his d100 event-slash-encounter table a while ago. Earlier inspiration comes from the Hazard System by Brendan S and some parallel thinking by David Black and Chris McDowall a couple years ago (which had prompted me to work on the same kind of table for Macchiato Monsters).
(Yeah, I made an HTML joke. I'm not feeling well today, okay?)
So for the next while I'll be dropping the 2d6+1d6 random encounter model and try this thing out. The monsters are from level 1 of B4: The Lost City because that's what I'm running this week. In your game, BOD points can be treated as hits or CON/STR, depending on how easy it is to recover HP.
