Looking for random dungeon / Single player rules


Homebrew and House Rules


I am looking for some random dungeon making tables or single player (DMless) rules. Does anyone know of any that may exist?


Fortunately I saved my 1st edition AD&D Dungeon Masters Guide. On page 169 Appendix A: Random Dungeon Generation there is a set of tables that could easily be adapted to the Pathfinder game. You start with a room or chamber with a staircase leading down from the surface the room typically is assumed to be empty and your character(s) are assumed to have just descended the stairs from the surface. The stairs are at the southern end of the room and the room is a square room 30 feet by 30 feet with a 20 foot high ceiling, all walls are made of stone blocks and the dungeon is underground. A side from the staircase descending through the southern wall equidistant from west and east walls, there are 10 foot wide passages with 10 foot high ceilings leading out of the middle of the west, north, and east walls. These corridors continue on into the darkness beyond the range of your torchlight, latern light, or low light vision, whatever the range of your method of seeing in this unlit dungeon, the corridors extend beyond that. We'll call this distance the "seeing distance" if you like.

I'm going to paraphrase the tables presented in that book, so I don't get into copyright troubles, they are fairly simple anyway.

If you choose to go down any of these three corridors, and traveling the "seeing distance" down that corridor, you consult table 1 after rolling a 20-sided die.

Table 1: Periodic check
d20 Result
1-2 The corridor contiues straight for another "seeing distance" from your current location.

3-5 There is a door, roll d20 and consult Table 2.

6-10 There is a side passage a "seeing distance" ahead from your current position, roll d20 and consult table 3 to determine wall(s) and direction(s) of the side passage, and check width on table 3.a, the corridor continues off in the distance past the side passage(s) into the darkness.

11-13 The passage turns at the "seeing distance", roll d20 and consult table 4, and check width of passage on table 3a.

14-16 The passage leads to a chamber at "seeing distance", roll d20 and consult table 5.

17 There are stairs ahead at "seeing distance", roll d20 and consult table 6.

18 The passage ends at a dead end at "seeing distance" from your current position.

19 You may have sprung a trap at your current position, roll d20 and consult table 7 to determine type of trap, the passage continues past the trap into the darkness at seeing distance.

20 You have a wandering monster encounter, roll a d20 and consult the appropriate wantering monster encounters table(s).


Table 2: Doors
Location of the door (all doors are assumed to be closed)
Die Result
1-6 door on left wall at "seeing distance".
7-12 door on right at "seeing distance".
13-20 passage ends at door directly ahead at "seeing distance".

after consulting above table roll a d20 and consult table 2a.

Table 2a: The space on the other side of door if opened.
"You open the door to find ..."
Die Result
1-4 a parallel passage to the doorway, roll d20 and consult table 3a to determine width.

5-8 a passage straight ahead, roll d20 consulting table 3a to determine width.

9 a passage 45 degrees ahead, roll d20 consulting table 3a to determine width.

10 a passage 45 degrees behind, roll d20 consulting table 3a to determine width.

11-18 a room, roll d20 and consult table 5.
19-20 a chamber, roll d20 and consult table 5.


Table 3: Side passages
Die Result
1-2 left 90 degrees,
3-4 right 90 degrees,
5 left 45 degrees ahead,
6 left 45 degrees behind,
7 right 45 degrees ahead,
8 right 45 degrees behind,
9 left curve to an eventual 45 degrees ahead at "seeing distance",
10 right curve to an eventual 45 degrees ahead at "seeing distance",

11-13 passage ends at "seeing distance" forming a 'T' with another passage at a right angle to the passage your currently in.

14-15 passage splits in two at "seeing distance", forming a 'Y', with left fork going 45 degrees ahead and the right fork going 45 degrees ahead from the passage your currently in.

16-19 The passage bisects another passage at right angles a "seeing distance" ahead, forming a 4-way intersection.

20 passage ends at an 'X' formed by two other passages a "seeing distance" ahead, the passage your currently in forms a fifth passage at the bottom of the 'X'.

After consulting the above table roll a d20 and consult table 3a.

Table 3a: Passage width
d20 Result
1-12 passage two 5-foot squares wide.
13 passage three 5-foot squares wide.
14 passage four 5-foot squares wide.
15 passage five 5-foot squares wide.
16 passage six 5-foot squares wide.
17-18 passage one 5-foot square wide.
19-20 roll d20 and consult Table 3b Special Passages.

Dark Archive

Dungeon Bash did the job in 3.5, though it requires some small retooling for Pathfinder. I've done some work in that regard, but they are of little good without the core DB stuff.


Table 3b: Special Passage
d20 Result
1-4 Passage is eight 5-foot squares wide with 5-foot wide columns down center one column every third 5-foot square with two empty 5-foot squares inbetween columns. The passage continues into darkness.

5-7 Passage is eight 5-foot squares wide with a double row of 5-foot wide columns. Each column is two 5-foot squares from the nearest wall, with a central space of two 5-foot columns between the rows down the center, each column in a row fills every third square in that row, and is thus seperated by two 5-foot squares from each other in each row. The columns are lined up to form squares down the center of the passage.

8-10 Passage is ten 5-foot squares wide with a double row of 5-foot wide columns. Each column is two 5-foot squares from the nearest wall, with a central space of four 5-foot columns between the rows down the center, Each column in the row fills every fifth square in that row and is thus seperated by four 5-foot squares from each other in each row.
The columns arew lined uo to form squares down the center of the passage.

11-12 Passage is ten 5-foot squares wide, with a double row of columns, two 5-foot squares to the right and two 5-foot squares to the left, each row of columns supports upper galleries 2 squares wide 10 feet above the floor.

13-15 Passage is two 5-foot squares wide and flooded with water flowing down the passage forming a stream.

16 Passage is three 5-foot squares wide and flooded with water flowing down the passage forming an underground river.

17 Passage is four 5-foot squares wide and flooded with water flowing down the passage forming an underground river.

18 Passage is eight 5-foot squares wide and flooded with water flowing down the passage forming an underground river.

19 Passage is twelve 5-foot squares wide and flooded with water flowing down the passage forming an underground river.

20 Passage has a floor 200 feet below the entrance forming a chasm four 5-foot squares wide.

But creating a while dungeon level at a time is not what one wants if one intends to be a solo player without a GM. What you want then is a series of tables that reveals information at the same time as the player character and hence the player would get it. That way as a solo dungeon player, you don't know what's behind that door until you open it, or listen or whatever.

(remember roll a d20 afterwards and recheck on table 3a to determine the new width of the passage after it turns.)

No problem, that is a fantastic site, and it creates a dungeon, a good GM tool, and I like the random planet generators too, but to have a solo adventurer play it, you'd need to breakdown each room description into a bunch of number index cards.

I did this once. Someone other than the player prepares the deck of dungeon cards with all the descriptions and secrets. On one side of each card is a small map of the room or encounter area in question, and at every exit is a number which refers to a numbered card, if there are containers, they have numbers too, if one opens a container, the player pulls the container card and finds out what's in it, whether trap or treasure, if he opens a door, then he pulls another card to find out what's on the other side. Some cards have combat encounters on it, and the player himself runs the encounter rolling dice for both his character and his opponents, all monsters are automatically assumed to attack, not much opportunity for roll playing here.

The deck of dungeon cards does the same thing as the random tables do, though perhaps with some more intelligently thought out encounters.

The Mythic Game Master Emulator is a product that has received high praises. It is not a dungeon generator per se, but a system-neutral campaign/adventure generator!

It might be a good product. I don't have much money right now, so I just use RPGs that are on my shelf, for other cheapskates out there I'm going to continue throwing out these random dungeon generating tables. It takes time to type out this stuff, so I'm doing a little here at a time. I hope to eliminate some ambiguities that the original tables have about how to draw the rooms and corridors on the grid. It is primarily for this reason that I keep the old first edition DM's guide, as the later editions don't have these tables in them. They have random monsters and treasures, but no tables for generating dungeons on the fly. Perhaps this mythic game engine does the same thing these tables do, I don't know cause I don't have it. One of the problems with buying stuff over the Internet is you don't get to browse, you buy it and then find out what's in it. Its kind of a pity that Borders Bookstores are going out of business, as I like browsing in their stores and if something really catches my eye I buy it.

The next table is of course that for the number of exits and their location. Instead of doing it the way the ist edition DMs guide does it I have my own idea, Tables 5c-g are the result. The main difference between rooms and chambers is that with rooms the exits have doors, which chambers they do not.

Tables 5c-h Number and Exit locations for Rooms and Chambers
These tables assume straight walls each is categorized by length, and one rolls the chance of an exit for each five-foot square in the length of the wall, thus for a 2 square long wall, one rolls a 1d4 and a result of 1 indicates the presence of an exit for each square rolled for the possibilities are 0 exits, 1 exit or 2 exits for this 10 foot long (2 five-foot squares) wall.

I really like these tables. If you have anymore of them please share them.

Thank you for your time.

I've looked at that and it seems very interesting. Would you be willing to share the pathfinder stuff you have made for it?
