Low-Life Encounter Table (Version-1)

Here's a low-life encounter table meant to fill-out a dungeon with a bunch of minor encounters to have a dungeon teeming with a host of critters but not all party killers. It's inspired by an excellent post over at Elf-Maids and Octopi (most of the entries lifted from there really), I also made use  of some one hit point holmes monsters from Zenopus Archives and some of the Swords and Wizardry SRD.

I'd use this table 50% of the time for random level 1 encounters, 40% for level 2, 30% for level 3, 20% for level 4, 10% for all deeper levels unless really remote or hard to reach sub-level. I'd likely increase monster probability by about 50% to make up for the number of not too dangerous low-life meant to be there in a busy dungeon.

Stats are for S&W which is compatible with my house rules and lots of other folks games.
