How the numbers work

Chance of an item = slot chance Γ— (item weight Γ· total weight of the slot).

Chance of at least 1 = 1 βˆ’ product over slots of (1 βˆ’ that item's chance in the slot). Slots are rolled independently.

Expected amount = sum of chance Γ— average quantity ((min + max) Γ· 2). Treat it as an average over many openings.

Weights and chances are the values in the game's loot tables. Rows with zero weight never drop and are left out; identical rows in one slot are merged.
