Treasure

Use a treasure trade-out system similar to that presented in Swords & Wizardry.

• For each 100 gp worth of treasure, there’s a 10% chance to roll on the Minor (100 gp) Treasure Trade Outs table.
• For each 1,000 gp worth of treasure, there’s a 10% chance to roll the Medium (1,000 gp) Treasure Trade Outs table.
• for each 5,000 gp worth fo treasure, there’s a 10% chance to roll the Major (1,000 gp) Treasure Trade Outs table.

These chances stack/overlap. Take a treasure worth 5,000 gp, for example. It gives a 10% chance to roll on the 5,000 gp table and five 10% chances to roll on the 1,000 gp table and fifty 10% chances to roll on the 100 gp table.

For large treasures, rather than rolling many times for magic items, we can use the expected value of a binomial random variable — i.e., the probability (10%) times the number of rolls.

How may minor magic items might be in a 2,000 gp treasure? 2000 ÷ 100 = 20, so we expect a 2,000 gp treasure to yield two minor magic items.

>>> (2000/100) * .1
2.0

Take an 18,500 gp treasure as another example. That yields nineteen minor items, two medium items, and 16,400 gp of non-magical treasure.

>>> (18500 / 100) * .1
18.5
>>> (18500 / 100) * .1
18.5
>>> (18500 / 1000) * .1
1.8
>>> (18500 / 5000) * .1
0.30000000000000004
>>> 18500 - (19 * 100) - (2 * 100)
16400
