2013-08-21 One Roll Dungeon Stocking

When I stocked my dungeon yesterday, I used the Moldvay Dungeon Stocking procedure. To be honest, my wife used it. The two tables are somewhat confusing.

I used the Moldvay Dungeon Stocking procedure

Moldvay:

||CONTENTS||||TREASURE| ||:--:||||:--:| |d6|Result|d6|Monster|Trap|Empty| |1–2|Monster|1|Yes|Yes|Yes| |3|Trap|2|Yes|Yes|No| |4|Special|3|Yes|No|No| |5–6|Empty|4–6|No|No|No|

I couldn’t find a blog post translating Moldvay’s dungeon stocking table into a single table. I’m sure I saw it somewhere. That would have helped us. (Edit: I guess I was remembering this discussion of the OD&D restocking procedure by Sham.)

this discussion of the OD&D restocking procedure

Let’s do it ourselves, then. Writing out all the results:

     1   2   3   4   5   6
 1   M$  M$  M$  M   M   M
 2   M$  M$  M$  M   M   M
 3   T$  T$  T   T   T   T
 4   S   S   S   S   S   S
 5   E$  E   E   E   E   E
 6   E$  E   E   E   E   E

Counting occurences:

+----+-----------------------------+
| #  |    Contents and Treasure    |
+----+-----------------------------+
|  6 | Monster and treasure        |
|  6 | Monster                     |
|  2 | Trap and unguarded treasure |
|  4 | Trap                        |
|  6 | Special                     |
|  2 | Unguarded Treasure          |
| 10 | Empty                       |
+----+-----------------------------+

Transforming this into a d36 table:

+-------+-----------------------------+
|  d36  |    Contents and Treasure    |
+-------+-----------------------------+
| 1–6   | Monster and treasure        |
| 7–12  | Monster                     |
| 13–14 | Trap and unguarded treasure |
| 15–18 | Trap                        |
| 19–24 | Special                     |
| 25–26 | Unguarded Treasure          |
| 27–36 | Empty                       |
+-------+-----------------------------+

Or divide it by two to get a d18 table:

+-------+-----------------------------+
|  d18  |    Contents and Treasure    |
+-------+-----------------------------+
| 1–3   | Monster and treasure        |
| 4–6   | Monster                     |
|     7 | Trap and unguarded treasure |
| 8–9   | Trap                        |
| 10–12 | Special                     |
|    13 | Unguarded Treasure          |
| 14–18 | Empty                       |
+-------+-----------------------------+

Too bad there is no such d18. We should change that to a d20 table. Let’s see if we can do it using Labyrinth Lord.

+-------+----------+----------+
| d100  | Contents | Treasure |
+-------+----------+----------+
| 01–30 | Empty    | 15%      |
| 31–60 | Monster  | 50%      |
| 61–75 | Trap     | 30%      |
| 76–00 | Unique   | var.     |
+-------+----------+----------+

We just multiply the percentages from the table:

+----------+---------------+-------------+
| Contents | With Treasure | No Treasure |
+----------+---------------+-------------+
| Empty    | 4.5%          | 25.5%       |
| Monster  | 15%           | 15%         |
| Trap     | 4.5%          | 10.5%       |
| Unique   | 25%           |
+----------+---------------+-------------+

We could simplify the above by rounding to increments of 5% and translating this to a d20, reusing the order from the d18 table:

+-------+-----------------------------+
|  d20  |    Contents and Treasure    |
+-------+-----------------------------+
| 1–3   | Monster and treasure        |
| 4–6   | Monster                     |
|     7 | Trap and unguarded treasure |
| 8–9   | Trap                        |
| 10–14 | Special                     |
|    15 | Unguarded Treasure          |
| 16–20 | Empty                       |
+-------+-----------------------------+

It’s very close to Moldvay, I’d say. And it’s probably less confusing. I can’t count the times I got confused by the Moldvay tables. 😄

Reordering it for excitement, I guess:

+-------+-----------------------------+
|  d20  |    Contents and Treasure    |
+-------+-----------------------------+
| 1–5   | Empty                       |
|     6 | Unguarded treasure          |
|     7 | Trap and unguarded treasure |
| 8–9   | Trap                        |
| 10–12 | Monster                     |
| 13–15 | Monster and treasure        |
| 16–20 | Special                     |
+-------+-----------------------------+

I need to stick this into my campaign book.

I would... ah, nonsense, I will change the special to a little less and the empty to a little more. Just because. ;)

“Special” needs a bit more work, that’s true. 😄
