Loot drop item stats rolls

A simple diagram simulating item/loot drop rates with different stats.

There are 3 examples:

Simple stat roll that randomly picks 1 out of 3 options with a value between 40 and 70

Stat rolls that randomly pick 2 options out of 5

Affixes and stat rolls that ensure each affix category has at least one option and 2 more options are randomized.
