In variants that implement object lookup: looking up an object should show that object’s relative probability within its own class.

Statistics that might be more useful to players, but harder to estimate, include the overall generation percentage for an object per level in each branch and per deathdrop, and whether or not monsters can generate carrying it. The overall percentages are tricky because object class distributions vary per branch, and it’s hard to estimate the amount of rooms in a level. Which items generate with monsters is less tricky but would need significant refactoring to avoid coupling the object lookup code to the monster generation code.
