Non-Linear Dungeon-Making: Variant

I wanted to offer an alternative method for setting up tunnels in non-linear dungeons. Consider the illustration on the left, which is similar to the illustration in SubMethod II for the pre-connected method, and which may be used as a substitute if you don't want to use the "clock" method. It's basically an expansion of the d8 variant described in the other post. For this variant, you would check where a door leads by rolling a d10.

The rooms numbered 1 through 8 represent directions. Room 9 is the starting point, with one "sample" door in each of the four directions.

If, for example, you were checking where a door in the north wall of a room leads, you would roll a d10. Rolling a 1 means that the door leads due north, to Room 1 in the illustration, or in that general direction. You would extend the white corridor stub to the north so that it would connect Room 9 and Room 1. If, instead, you roll a 5, that would indicate that the north door leads south, which would mean the corridor would go around Room 9, and has two possible routes: the red path to the left or the blue path to the right. Flip a coin, or roll a d6: tails or odd numbers means use the left-hand path, heads or even numbers means use the right hand path.

If you would like more variety, you can use the coin toss or even/odd roll every time you have a choice between a red path and a blue path, so that a corridor could take either the shortest route or the longest route to reach its destination. In cases where there are three choices (red, white and blue,) any result of 5+ on 1d6 means use the white path, or go straight. So, the route from the north door in Room 9 to Room 1 could be short and straight, or make three left turns or three right turns and spiral around Room 9 on its way to Room 1.

On a roll of 9, the corridor leads back to the starting room. Roll a d6 for the location of the second door:

  1. North Wall
  2. East Wall
  3. South Wall
  4. West Wall
  5. Ladder Up/Down, center of room
  6. Stairs Up/Down, center of room

Connect the first and second door, making sure to include a ladder or staircase in the opposite direction if the result was 5+.

On a result of 0 for the d10 roll, the door goes nowhere: it opens on a blank wall or a short, dead-end tunnel. You can roll a d6 for tunnel length (in squares,) treating a 6 as a length of 0, and rolling another d6 to have the tunnel turn left or right after 2 squares.

All of this assumes that you know which walls in your starting room has exits, possibly because you've already rolled some kind of door check (for example, rolling four d8s and reading the result off the d6 table above, with 7+ meaning no door.) But an alternative approach would be to roll four d10s all at once and reading the result as if you were using a drop-dice table, with the positions of the dice indicating the approximate position of the door, and the result indicating where the door leads. Or make the number of d10s rolled variable by rolling 2d3 first for the number of dice to roll.

Once you have your network of corridors leading out of your starting room, you can use the junction table from either SubMethod II or the pre-loaded leximorph method, along with some method of checking every 60 feet of corridor for additional exits, to fill in extra details.

Pre-Connecting Random Non-Linear Dungeons, SubMethod II

Next up on our look at modifying random dungeon generators to make them more non-linear, I wanted to look at a different approach to rolling for a corridor's destination. SubMethod I relies on room numbers as references pointing to physical locations. This works great if you want to use room numbers as your way of keying rooms, but not so great if you prefer letters or multicharacter labels. It doesn't allow for nested structure labeling (room 1 as a main room and 1A/1B as subrooms.) And it doesn't work well at all if you want to use numbers for any point of interest, like a trapped intersection, not just literal rooms.

The solution is to use some kind of relative numbering system, something better than "roll dice and add a modifier to get the actual room number". One answer is to number the relative positions around the current room, for example using 12-hour clock positions, with 12 o'clock as the area due north of the current room, 3 o'clock as due east, 6 o'clock as due south, and 9 o'clock as due west, so that you can roll a d12 to select the room that is in that relative position as the destination of a corridor. In the illustration to the left, the main room in the center has a door in the north wall. We would roll a d12 for the destination of that door; a result of 12 would mean that the corridor heads straight north to Room 12, while a 7 would mean that the corridor turns west for about 40 feet, then south until it connects with Room 7.

(Incidentally, I've been using Alex Schroeder's Gridmapper for these quick demonstration pics. I only recently found out about it, but I've been out of the loop for a while, so probably everyone already knows about it. I work on the pic in another tab as I'm writing the blogpost, then use a Chrome extension called Nimbus Screenshot to quickly save the pic and insert it into my post.)

An alternative that might be easier for some people would be to mentally overlay a tic-tac-toe board over the map of the area immediately around the starting room, with the center square as the current room, and number the other squares clockwise from 1 to 8, starting at the top. Use a d8 with this method to indicate the destination square.

In either case, the corridor heads towards the indicated destination. If the area hasn't been mapped yet, you can roll to see what is in the area using a d10:

  • On a 0, the passage dead ends.
  • On any result up to 6, there's a junction. Roll again twice for destination with either the d12 or d8 (whichever method used above,) with doubles indicating that the junction is a turn rather than an intersection.
  • On any result over 6, there's a room. Roll on any table you prefer to determine room size, shape and description.

You can change the target number of 6 to a different number to shift the proportion of corridors to rooms, or use the junction table on the pre-loaded non-linear dungeon post instead.

If there is a room or corridor already in that location, the new corridor connects with it. (Notice that we don't need to connect with a room, or even with a keyed location...)  Alternatively, for corridors, use the d10 table for crossing pre-existing corridors from the SubMethod I post, which will add a chance for sublevels above or below the main level.

Pre-Connecting Random Non-Linear Dungeons, SubMethod I

To continue on the topic of making sure randomly-generated dungeons contain loops to avoid linear designs, let's look at the second method. The first method, you will recall, is to include the loops beforehand and built your dungeon around that skeleton, which I called "pre-loading". I was almost going to call the second method "post-directing", to contrast it to "pre-loading", but I didn't like that name. I'll call it "pre-connecting" instead.

The fundamental idea, remember, is that instead of waiting for the random twists and turns of a corridor to connect to a room, you roll immediately for where the corridor goes and adjust the shape to fit. You are thus connecting the rooms in advance, before knowing where the corridor actually appears to lead. Since most GMs number their rooms, the brute force method of rolling for connections would be to just roll the room number. For example, in the image to the left, if we begin in Room A and need to know where the door in the upper right leads, we could roll a d4 and read the result as the room number. If the result is 1, we draw the corridor turning north (upper blue squares,) then west to connect to the door in Room 1. On a 2, we extend the corridor east (upper red squares) until we connect to Room 2. On a 3 or 4, we extend the corridor south (green squares) and then turn east (lower blue squares) or west (lower red squares,) depending on whether we are connecting to Room 3 or Room 4.

The problem with this is that we need a die roll that matches the number of rooms in the dungeon... and we might not know how many rooms the dungeon has yet. Instead of rolling directly for the room number, then, we could instead roll for the relative room number. We could roll a d10 on the following table:

RollRoom #|RollRoom #
1Current Room - 4|6Current Room + 1
2Current Room - 3|7Current Room + 2
3Current Room - 2|8Current Room + 3
4Current Room - 1|9Current Room + 4
5Back to Current Room|0To Distant Room, Same Direction

In other words, subtract 5 from the current room number, then add the result of a d10 to get the destination room number. This means that most corridors will lead to nearby rooms: rooms you have just drawn, or rooms you are about to draw.

If the result is less than 5, it's one of the previous four rooms you've drawn. Draw your corridor as straight as possible towards that room. You might have to make one or two turns, if the corridor starts in the opposite direction (the way Room 1 in the example picture above is west of the door in Room A, so the corridor must make a U-Turn to connect.) You can still use the random corridor shape tables from whatever generator you are using to test the corridor every 60 feet or so for side passages or doors.

If the result is 5, the corridor re-connects with the room it leaves. Either there are two doors in the room and the corridor connects them, or the corridor splits into a Y or T and forms a loop that way. Again, check every 60 feet, or possibly even every 30 feet, for doors or branches off the main corridor.

If the result is more than 5, the corridor leads to a new room. assuming you haven't drawn those rooms yet. The general direction of the room is the general direction the initial door or doorway is facing. You can use the standard tables from whatever generation system you are using to test the corridor every 60 feet for turns or side passages, or you can roll a d10 for corridor length:
  • on a 0, there is no corridor and the door leads directly into the new room;
  • on a 1-6, multiply the result by 10 for the length of the corridor;
  • on a 7+, draw 60 feet of corridor and then test for turns, doors, or side passages.
If the result is a 0, the corridor connects to a distant room in the same general direction. Find the first numbered room on the map in that direction and use that room number as your "current" room, then roll on the table again for the destination. If the corridor's general direction is into an unmapped area (quite possible when you've just started mapping,) postpone mapping the corridor until you've mapped that area.

For the first five rooms of a map, use the results as the raw room number. If a corridor has to cross other corridors or rooms to reach its destination, roll on the following table:

d10 RollResult
1-4corridor runs under area
5secret door connects to area
6-9corridor runs above area
0dead end, no connection

If the corridor runs under or above the area, there will be stairs just before it crosses the area, and stairs on the other side. Optionally, there are stairs on even rolls and ladders on odd rolls.

If the corridor ends, either with a secret door or a true dead end, there is no need to worry about finishing the connection on the other side of the already-mapped area.

Pre-Loaded Random Non-Linear Example: Blood of Prokopius

I've been sick for the last few days and unable to write the next installment of the random non-linear dungeon series, so I'll instead link to an example dungeon by FrDave at the Blood of Prokopius blog: The Sunken Halls of the Ape Brotherhood. This uses the leximorph-based pre-loading method to establish the main corridor structure, although instead of randomly-selecting letters using a table, he picked the letters "A", "P", and "E" from the most important descriptive keyword in the dungeon title.

The main thing I'll note is the loops and branching paths, which is what we are looking for in these methods. If entering from the south, there are three routes to choose from, all of which can connect to the same areas, forming a large loop: westwards from the western or middle branch to the apex of the "A", northwards through the flooded chambers, then southwards to the Bizarre Ice Gateway and out the eastern branch of the "E". There are several smaller loops as well: the apex of the "A" and the entire "A" form nesting triangular loops (although you'd have to clear some debris in one area,) the square loop of the "P", the loop(s) between the middle and eastern branches of the "E", and multiple loops of rooms off to the side of the major corridors.

On the whole, very loopy! And a tough environment, too!

Pre-Loading Random Non-Linear Dungeons

In the post on guaranteeing that a randomly-generated dungeon is non-linear (contains loops,) the first technique I mentioned was to start with a dungeon structure that already contains these loops, then generate rooms and additional corridors that connect to that structure. I call that technique "pre-loading". The predefined structure is a tunnel template which you then modify with dice rolls.

A long time ago, I toyed with the idea of leximorphs: using letters of the alphabet as if they were geomorphs. This could be used for a tunnel template. Assume that your dungeon is divided into sectors, for example four quarters. If you randomly select a four-letter word or character string, assign one character to each quarter, and draw them on a map so that each character touches the adjacent characters, you wind up with a network of tunnels. Some letters have loops built into them, for example "A", "B", "D" and "O". This guarantees at least a little bit on non-linearity. The loops can be drawn with curves or as angular shapes, as in the example image. Other curved strokes can be straightened or turned into angles as well, as desired.

There are a couple sources for random word generation, for example the random page feature of Wikipedia. But one quick option is to use this d10-based table:

Roll (d10)Letter Pattern
9lowercase g

I chose mostly letters with loops in them, although I did include three letters that do not contain any loops (T, L, and X,) just for variety. Roll a d10 once for each sector on your map. Optionally, roll a d4 for rotation of each letter (1= normal, 2= turn 90 degrees clockwise, 3= turn upside down, 4= turn 90 degrees counterclockwise.) Make sure each letter touches the adjacent letters, so that there aren't any disconnected lines. This is your base tunnel template.

At every corner or junction between letters or within each letter, roll to see how the two tunnels connect (d6).

  1. Ordinary Junction
  2. Trapped Junction
  3. Trapped Junction (disabled)
  4. Minor Obstacle (debris, pool of liquid)
  5. Door
  6. Room

Finally, check both sides of the tunnel every 60 feet for doors or branches (d8).

  1. Blank Wall
  2. Blank Wall with Secret Door
  3. Branch/Side Passage
  4. Two Diagonal Passages
  5. Blocked Passage
  6. Door
  7. Pair of Doors, side by side
  8. Stairs

I am assuming here that you are using tables borrowed from Appendix A or another random dungeon generator to roll for size and shape of rooms, type of door, what's behind each door, or other details as needed.

Random Non-Linear Dungeons

There was a recent forum discussion about non-linear or "jaquayed" dungeon generation. Justin Alexander introduced the term "jaquaying" to describe a method of non-linear dungeon design that uses lots of loops and alternate paths to avoid the stifling, railroaded feel of linear dungeons. What the forum discussion centered on was the problem of random dungeon generation, for example Appendix A in the AD&D Dungeon Master's Guide. Most random dungeon generators only produce loops by accident.

What Appendix A does, and many alternative generators copy, is it generates shapes or paths. You start at Room 1 and roll for doors or exits on each wall. Each exit leads to either another room or a corridor heading in some direction. Every so many feet of traveling down the corridor, you roll to see if the corridor turns, branches, ends in a T, or intersects with another corridor.

As you generate corridors (or, for that matter, additional rooms that have their own set of exits,) there is a random chance that the direction indicated would lead into an already mapped area, creating a loop. The chance improves as the map fills up. This means that such loops are more likely to be small, which means less of an opportunity for players to exploit the structure of the dungeon to bypass dangerous areas, slip around behind opponents, or evade pursuit. You wind up with less interesting dungeons that way.

My opinion: you really need to move away from randomly-rolled shapes if you want a better chance of getting loops. The way I see it, you have two choices:

  1. Start with a network of major corridors that already includes loops, then randomly connect rooms and minor corridors to that base structure.
  2. Roll for the destination of corridors or exits, instead of rolling for their shapes.
The best way to explain #1 is to look at the way Appendix A handles starting areas. The first dungeon level starts with either a random room (jump to Table V) or one of five starter areas with a good choice of rooms and passages leading off from the first room. To force loops into your random dungeon, you could similarly have five pre-defined corridor networks that include loops and alternate paths, then check each corridor every 60 feet for branching corridors or doors to build your dungeon around that framework.

For #2, you would replace any roll for direction with a roll for destination, for example rolling for a room number. You would then connect an exit or passage to that destination, adjusting the shape of the corridor to fit the map. As long as there's a possibility of rolling an already-mapped room as a destination, you will get some loops in your dungeon.

You can, of course, mix the two methods with each other or with the random shape method.

I have a couple experimental approaches to each method that I will present in separate posts.

The Infamous OD&D Caller

I was going to start posting a series on alternative corridor generation for random dungeon creation, but then I was reminded about a recent forum discussion on the caller.

There's not a lot of information about what a "caller" is in the original three booklets. Callers are mentioned in a play example on pages 12-14 of Underworld & Wilderness Adventures. The book doesn't say what a caller does, but in the example it's things like "We're going downstairs," "Three of us listen at the door," "Two of us throw our weight against the door while the others get ready for combat." Based on that example, some people have come to the conclusion that OD&D is a bad RPG because it deprotagonizes players. The caller decides what everyone does, and the other players just have to shut up and do as they are told.

Why on earth would an RPG do something like that?

Why would players roll up characters, give them a name, and buy equipment if they weren't actually going to do anything from then on? Why wouldn't OD&D instead be a one-on-one game where one player controls an entire party?

Some people have thought of that line of logic and thus ask for clarification on what a caller is, or why the rule exists. But the short answer is: it's not a rule. It's just a convenience. Somebody tells the referee what everyone is doing. It doesn't mean there is no discussion among the players, or that a player can't disagree with what someone else says they should do. The example in U&WA skips over what other people are saying, because it's supposed to be an example of how the referee moderates what's going on. Players aren't supposed to worry about that section at all.

The Fantasy Trip was published only a few years after D&D. It's not D&D, but it has some D&D features, including a tradition of using a caller. Perhaps D&D should have had something more explicit, such as this passage from In the Labyrinth, the TFT campaign guidebook.
"CHOOSING A LEADER. Ask the players if they want to designate a leader. They don't have to — but if they do, you can assume their party is a little quieter as they travel. If they DO choose a leader, you will speak to the leader when asking what the party does (at least until a combat situation, when it's likely to be every man for himself). Of course, a player can always have his figure DISOBEY - and for some figures, this would be quite in character." (TFT:ITL, p. 33.)
This makes it sound more like a rule, but even here, it's aimed more at the referee than at players. What do referees do when players don't designate a caller or leader? They should treat the party as being a little noisier. That's it. There's no other rules in that paragraph.

Even this glosses over the fact that there are different levels of caller/leader. Some groups might just have someone make decisions on which direction to go and nothing else. Others might have the leader assign tasks to each character, although the player of that character decides how to obey, if they obey at all. In practice, I don't think I've ever seen any GM ask who would be the caller, nor have I seen players make a formal decision on who would be the caller. It was always informal. The GM would ask, "What are you going to do?" and someone would reply, "We go left." If no one said otherwise, that person was the caller.

The only hard rule I'd use is: what players say to each other happens in the game world, while what players say to the GM is happening in the real world. That means that if people are arguing over which way to go, their characters are arguing, too, and therefore monsters can hear them. This means extra wandering monster rolls.

Things like a caller saying "We go left," or a player asking "Do I understand what the goblin is saying?" do not happen in the game world, so monsters can't overhear them. They basically happen outside of time.

Blog Revamp

So, I really really should get back to blogging. Especially since I have been posting some ideas on the OD&D boards recently and should mirror them and perhaps expand on them here, rather than let them hide in the forum.

As it so happens, though, there's something else that just happened which may impact this blog.

Control of LiveJournal as a blogging platform has been transferred to SUP Media LLC, a legal entity based in the Russian Federation. This decision stems from the urge to become closer to our users, most of whom live in Europe and Russia. Every LiveJournal user will be offered to sign the new User Agreement with SUP Media. Paid services, however, will still be provided by Live Journal Inc.

When LiveJournal's ownership changed a couple years back and everyone was worried about the changes, I backed up my LJ account, as many others did. But I left my blog there rather than moving it somewhere else. But I'm thinking now is the time to just delete that profile and salvage what I can.

Some of my posts there were, in fact, about some RPGs I was designing. I'm thinking of re-posting them here, even though these projects are either abandoned or on the backburner. The one way, way in the back. Just in case some of the material might be useful to someone. All these posts will be marked as reposts with the original date noted, and they will be interspersed with new stuff I'm working on now, so I'm not going to swamp my blog with a rehash of out of date material.

I was thinking of starting another Blogger blog for the non-gaming stuff. Most of my LJ posts aren't worth reposting, because they are only relevant to myself and the friends who were reading my posts back then. But I might repost some social commentary or other witty insights (ha!) on such a blog, maybe even get back into non-RPG blogging on an occasional basis. Haven't decided yet.

But the main non-RPG posts I felt were worthy of being saved were media commentary, mostly reviews of TV and movies, mostly fantasy and sci-fi. I enjoyed writing those and occasionally like to look up those old posts when someone brings up a movie like, oh, Camelot (1967) and I wonder "Hey, did I like that?" (Spoiler: No.)

When discussing blog-moving plans with my friend Colin, he suggested I could merge some of my non-RPG posts into this blog, The Nine and Thirty Kingdoms, and just use tags so people could filter out the material they don't want to see. And I thought, "Well, not most of that stuff... But the media stuff? Maybe?"

I know many of the RPG bloggers I read do include a lot of commentary about movies, TV, books, and comics in their blogs, but I've always tried to keep this an RPG-only blog. I wanted it to be very focused, since I figured most people who come here looking for terrain generation tips or random tables aren't interested in my opinion of The Fifth Element. (Spoiler: Again, No.) But on the other hand, I kept that stuff out because I had another place to post it. Even if I used that place less and less as the years rolled on.

Now that it's not going to be there anymore... Should I? How do people feel about me ranting about movies? Not all of which are fantasy and sci-fi, some of which would be very hard to relate to RPGs?

It wouldn't just be reposts, either. I've had the urge to write a thing or three about some recent stuff, especially the Doctor Strange movie, so I could post about that, too.

I'm just not sure how people are going to feel about that.

The Grubby Adventurer

I keep forgetting to copy quick ideas I post in forum threads over here, so that I don’t lose them. This is an idea sparked by a thread about the effects of grime vs. cleanliness.

Being on the road, camping in the wilderness, or exploring the underground is filthy work. Civilized people will tolerate some grubbiness, but after a full day of any such activity, characters are at half effective Charisma until they’ve had a chance to clean up. This mainly affects dealing with merchants, meeting new people, hiring help, and other negotiations. It may also affect the behavior of existing hirelings, within reason: the chambermaid responsible for preparing your bath isn’t going to quit because you haven’t bathed yet today, for example, nor will hirelings who do filthy jobs themselves, like stable boys, take exception to your grubbiness. It definitely does not apply to any mercenaries or retainers who have gone through the same grimy events. They know why you’re dirty, because they’re dirty for the same reason.

Some events can make you instantly filthy, for example crawling through sewers, having a chamberpot dumped on your head, returning from a battle covered in the blood of your enemies. This can also be used when dealing with groups that have unique ideas of hygiene or decorum, including wearing lower-class clothing to a party at the palace.

The penalty disappears as soon as you clean up. Pseudomedieval societies aren’t too demanding when it comes to hygiene: get the blood wiped off, wash your face and hands. That’s generally enough. Again, some groups may have additional standards of hygiene, or even lower standards: some areas will tolerate a week’s worth of stink instead of a mere day’s worth. Barbarians generally don’t care at all, or will have exotic standards. “I don’t want to speak to you, whelp! You have barely any tattoos!”
