Item Rarity Calculator

This utility will calculate the chance for any magical item to drop in the dungeons. It does NOT calculate the rarity from NPC sources (items you can buy). It is based on the information in Jarulf's Guide to Diablo and Hellfire including items, affixes, monsters, and all the information in Chapter 3.8. Special thanks to Jarulf for his guide and his insight into monster generation routines. This calculator would not have been possible otherwise.

Rarity: The first number is a percent and refers to the chance a game has to generate the item (all items to drop in a game are determined at game creation). This number is best used to compare the rarity of two items. The second number is the statistical number of games that would need to be cleared to find the item.

Best drop probability: Values are given for dungeon level, unique monster, normal monster, and dungeon source. This means that the probabilty listed 2nd may or may not actually be the 2nd best drop probabilty. I figured it would just be boring if there were nothing but unique monsters listed.

n, N, H refer to normal, nightmare, hell difficulties respectively.
