Stocking a Dungeon: Monster Activities

You’re stocking a dungeon. You’ve drafted all of the rooms, filled them with monsters and treasure and it’s looking as if it’s almost ready to be pillaged by a group of adventurers with questionable ethics. In their final moments, the monsters that you’ve placed should be doing something other than waiting for the sweet release of death.

Let’s add a little flavor to the daily routine of your randomly-generated creatures. Note that most of these only apply if the creature is at least modestly intelligent. Slavering beasts probably won’t engage in the bulk of these activities. You certainly get points for style if they do, though.


  1. Eating
  2. Eating (Again)
  3. Training

This should be easy. Monsters with patrols should roam to nearby rooms, mostly to check up on any heavy-traffic intersections. They’ll return to their ‘home’ room once they’ve spent a turn in their destination room. Monsters on patrol should be armed with a source of light and a sketched map of the dungeon.


Some monsters are needed to reset traps, ensure that hidden doors haven’t been used and left open and clean up any unsightly blights on their dungeon homes. These monsters should be equipped with some sort of protective armor and 10’ poles if they are going to be interacting with traps. They should also have lamp oil, fresh torches and candles, cleaning supplies and perhaps a sketched map of the dungeon with a 50% chance of having hidden passages marked.
