[MINIMAL SPOILERS!]
Greetings, all!
I've heard in D:OSII there are common (white), uncommon (green), rare (blue), epic (purple), legendary (orange), divine (yellow), and unique (gold) items. Ignoring unique items for now since they have predetermined stats, how do item rarities determine stats?
I've seen green items have a single + to something (STR, Thievery, etc.) sometimes with a secondary extra effect on weapons (like 10% to set Silence on a subject with no magic armor), blues have a + to two stats, and no appreciable difference in for purple gear.
Mind you, we're still in act 1 and have only found a single purple item and nothing more rare than epic.
