Ok, I wanted to make sure what I was about to contradict Here is a summary of how a specific BOD is chosen, for a GM or above tailor. 1. Choose the quantity needed (10, 15, 20) randomly 2. 33% chance to be exceptional 3. 92% chance to be small, 8% chance to be large 4. Randomly choose from among all available types. Should be 55 types for smalls, 14 for larges. Notice there is no distinction made between cloth or leather at this point other than how many are in the list of each. 5. If the type from step 3 is leather, then it has a 70% chance to be colored leather. 6. If if is colored leather, the chance for each color is: 60% spined 30% horned 10% barbed That's the order in which each attribute of the BOD is chosen, so you can derive the percentage to get any one specific BOD from there. I don't know why the exceptional bonus differs compared to what was stated years ago, but it's been the same since as far back as early 2004. If I had to guess, I'd say that it was originally intended it to be that, but it was changed based on testing or feedback at the time.
