One of my favourite things about combat in table-top role playing games is the random encounters. I always thought it a bit nasty or mean as the DM to deliberately pick creatures that you know have counter abilities to the players, which is one of the reasons I love encounter tables – you let the dice decide. I use a variation of this to throw things into disarray or just stir the imagination pot inside my head. This can be used for adventurers up to 10th level, but the average level increase should be 5th level.
Low Dungeon
Use this encounter Master Table in a magically active area, less than a mile deep, so true underdark type creatures (Pech, Duergar) should be rare. It should be travelled on a infrequent basis by commoners, though adventurers or patrols are still there to do what must be done.
Encounter determination should be made at pre-set times, such as when a door is opened, a group descends a level, a loud noise is made, or every three hours check for encounters. Normally the base chance is 1 / 20. For every three additional members travelling together, add +3. For loud noises, add +5. All adjustments are cumulative. So a group party with seven people smashing down a door would have 1+3+3+5= 12 / 20 to attract attention. This gives a real incentive for rogue-types to scout ahead, their chance would be 1 / 20. You may increase the base rate (normally 1) as high as 5 then add the miscellaneous adjustments.
Alternate Determination: If the current roll doesn't make sense, such as a building feature due to PCs making noise, reverse the numbers (14 into a 41). If this still doesn't work, odd roll drop down to the previous listing, even roll go to the next highest item listing.
How to use this table: You may use this table during the game for every dungeon encounter check. However, consider pre-rolling a “hot-list” of the eleven (2d6) most likely creatures encountered. This way you can use the Master Table, and the hot list changes per dungeon, without players knowing what a specific dice roll is on the Master Table. I most often use the hot-list for known threats in an area, for example, if enquiring about the dungeon, and the locals say cultists and ogres, these should go on the hot list. Anything from the Master table (actually anything in the monster books or in my head may end up in the adventure) but these are the most
Features: The encounter table has a number of environmental aspects. Just like with a creatures, if something doesn't ”make sense” to you, you don't use it. I recommend you try to incorporate it, even if something is illogical or out of place, describe it that way. If all of the other doors you find are made out of wood for medium sized creatures, suddenly you find a double set of metal doors for small creatures.
