Here is something I made up to help me with randomly stocking a dungeon with monsters for Labyrinth Lord, which is a retroclone of 1981 Basic /Expert D&D (available from Goblinoid Games link at top of main blog page).
I had to turn it into an image file to get it to display in a post.
The PDF version can be found here:
The NPC Details table is an aid for quickly determining the
Class, Alignment, Purpose (Motivation), and Condition (Health) of randomly rolled NPCs.
I never got around to making tables for anything past Level One of a dungeon. Although I could if I needed to I suppose.
