Treasure tables are, for better or worse, part of old-school RPGs. Since the intention is to make the Treasure Overhaul a very useful and broadly compatible book, it's important to understand the subtleties of historical treasure generation. The average treasure value of a given type is relatively easy to calculate. It's also deceptive. Averages are a good start, but if you only look at averages, you can easily miss the big picture. To make sure I understood the bones of OD&D and AD&D's famous treasure tables, I cobbled together a spreadsheet that runs through 100 at a time. No, you can't see it. It's _awful_. I'm reasonably confident it's correct, but it's not elegant. ## OD&D Treasure Type A1 --- Bars are cumulative. 200 trials. I ran many, many trials to confirm the general trends, but charts with 200 results are easier to read. ### **1. Null results** Around 8% of rolls for Type A1 result in 0gp. Around 20% result in less than 1,000gp. There's an argument to be made that unexpectedly high-value results (>150,000gp for A1) only feel "real" if there's a chance of unexpectedly low results. I'm still thinking this concept through. Take random encounter tables. Nobody insists that if a Random Encounter Table includes 3d6 level-draining PC-slaughtering Wights, it's only fair that it include 3d6 helpless Marshmallow Cuddlebugs. The low result isn't required to make the high result feel "worth it". There's usually a spread of results and deadliness, sure, but in OSR games, even a handful of Goblins can be dangerous. People would complain if a random encounter table was 10% empty. On the other hand, a random encounter table is only used some of the time. A treasure table is used every time (in theory). So a 0gp treasure is just moving the probabilities of a no-encounter roll to a different step. A 0gp result can also help with worldbuilding. When I rolled up my OD&D Hexcrawl (available on Patreon) I had a surprising number of 0gp results to explain. That's part of why I created the spreadsheet. I wanted to see if I was unlucky or incompetent. Turns out it was probably both. Hooray! ** --- Antonio J. Manzanedo ** ### **2. Gems and Jewellery** The structure of a treasure table, and cultural depictions of dragon hoards, suggests coins are important while gems and jewellery are accessories. The results (and plenty of documented wisdom) shows that this isn't true. Coins are a consolation prize. Gems are a lottery ticket that _could_ boost a small treasure into an enormous one. But the meat-and-potatoes of the OD&D treasure table is jewellery. --- Taken from Greyharp's Single Volume Edition. Treasure Type A1 has a 50% chance of including 3d6 pieces of jewellery. If the treasure includes jewellery, it's all but guaranteed it will dominate the result. You can see the cutoff on the chart. To match the usual at-table procedure, the sheet rolls jewellery and gem values in batches of 10. E.g. if I rolled a 36 on 6x1d6, I'd roll for 10, 10, 10, and 6 gem values. All you need is one batch of 10 hit 10x1,000gp and you've got 100,000gp. To put it another way, for Treasure Type A1, if you roll Jewellery, you get a minimum of 6 pieces. At the minimum value of 300gp per piece, that's 1,800gp. That's worth more than the _maximum_ roll for Copper and Silver coins. The jewellery table is the driving value behind treasure in OD&D. You could leave coins out entirely and barely notice. --- Values of each type of treasure, separated. 500 trials. ### 3. The Gem Lottery In OD&D, gems have a base value based on a 1d100 roll, and then a 1-in-6 chance to upgrade to the next highest value (or a list of higher values that can't be initially rolled), up to the incredibly unlikely 500,000gp. Gems are the lottery tickets of the OD&D treasure table. But "standard" upgrade, of 10x 1,000gp gems to 10x 5,000gp gems or 10x 10,000gp gems still only puts the Gem results in the midrange of Jewellery results. You can see that on the chart. There are a few results where Gems form the bulk of the treasure, but the solid and consistent mass of Treasure Type A's value comes from Jewellery. ### 4. Average Value Check Just to make sure I'm not totally crazy, let's run through some basic averages for OD&D jewellery. **OD &D Jewellery (Type A1) Average Calculation** --- **Roll** | **Value** | **Value** | **Rate** | **Product** 20 | (3d6x1000) | 1050 | 0.2 | 210 80 | (1d6x1000) | 3500 | 0.6 | 2100 100 | (1d10x1000) | 5500 | 0.2 | 1100 | | Average Per Piece | | | | 3410 | | Average Pieces Per Type A1 | | | (6x1d6) | 21 | | Average Per Type A1 | | | | 71,610 My Calculations (500 runs) | Rate | 0.5 | **36,358** | | Average | **35,805** That's pretty darn close, and it matches the values found by others. But this does suggest that Delta's famous XP/GP tables are incorrect, at least for OD&D (if I'm reading them correctly). ## OD&D Treasure Type H --- Bars are cumulative. 200 trials. Ah, the classic Hoard. In A1, Gems and Jewellery have same number of pieces (6x1d6). In H, Gems have 1d100 pieces, while Jewellery has 1d4x10 pieces. This provides more-or-less the same jewellery values, with the added boost of a high gem roll giving a higher chance upgrading gem values. In A1, there are at most 4 "batches" that can be upgraded. In H, there are up to 10. It's interesting that the top ~20% of Type A1 is above 100,000gp, while ~30% of Type H is above 100,000. Type H _feels_ larger, with its 1d100 gems and 6x1d10x1,000gp, but in practice it's all jewellery-dominated. A has a 50% chance of 6x1d6 pieces; H has a 50% chance of 1d4x10 pieces. The difference between 6x1d6 and 4x1d10 is not terribly significant. Dragons, the standard hoarding creatures in OD&D, do have a built-in age-related multiplier. "Very Young and Young Dragons are unlikely to have acquired treasure. Sub-Adult Dragons will have about half the indicated treasure for Dragons. Very Old Dragons can have as much as twice the indicated amount." ## AD&D Treasure Type A In AD&D, Treasure Type A is used for for the Lich, Locathah, Men (Bandits), Troglodytes, and the Squid Giant... for some reason. It's a mixed bag. --- Bars are cumulative. 200 trials. As usual, AD&D's procedure is OD&D + a layer of complexity. I did not implement the stone increase/decrease base value table. It's more complicated than OD&D's. I looked at it, and I tested out a few worst-case scenarios, but it's a horrible and recursive thing and I just can't be bothered. It provides for a runaway doubling of gem value (as in OD&D) but it's _so_ hard to implement cleanly (with my very limited skillset, at least). As my grandfather said, just before his homemade self-driving car took him over a cliff, there are times when you should code things properly and times when nested IF statements are good enough. Jewellery in AD&D also has a runaway increase. If the piece has gems (on a 51+), roll 1d8. On a 1, add 5,000gp and roll 1d6. If that's a 1, double it to 10,000gp and repeat, to a maximum of +640,000gp. There's a craftsmanship value adjustment step which I didn't implement. The point is to confirm that, in AD&D as well as OD&D, the "average" treasure value doesn't tell the whole story. Jewellery dominates the chart. ## Final Notes Treasure tables are fun. They are also very difficult to implement with at-table utility in mind. For a pre-generated dungeon, where the GM can sit back, roll, and type things into a calculator, they work just fine. But at the table, with the pressure of game flow bearing down on them, and the added pressure of fast math, they're a slog. I've also created a small OD&D hexcrawl and 3-level standard dungeon. They're available on Patreon. I sometimes post previews of the Treasure Overhaul on Bluesky.
