Not that it matters much, but I get a slightly different number than the calculator. Here's my computation
The chances of magistrates on dlvl 14 (and therefore Dreadjudge) is 10%.
There are 67 base items with the bows being 2x as likely which for the sake of probability is the equivalent of adding 8 new items = 75. In addition, bosses can drop rings, amulets, and books. To make these items more common the code has several base items for each: 4 for books, 3 for rings and 2 for amulets, which means another 9 = 84. So the probability of getting a specific weapon (non-bow) is 1/84.
The chance that the item has both a prefix and a suffix is 16.7%.
There are 24 prefixes which can exist on non-bow weapons which are between qlvl 15 and 31. However, + to hit items and + to hit (3), + damage (3), and + both (5) are 2x as likely so we add another 11 so the chance of an emerald prefix is 1/35.
There are 15 possible suffixes which can exist on non-bow weapons which are between qlvl 15 and 31.
When a boss drops something which can have a unique item associated with it there is an 84% chance that it won't be unique.
So, in sum, the chance of an Emerald non-bow (which has a unique item of the same type) of Slaying dropping is 3.18 * 10^-7. The calculator gives 3.52*10^-7.
Can anyone tell me where I went wrong?
