Didn't FFXI use some sort of random stat generator for some of their gear?
Some items can be augmented randomly. 99% of the time the result is a piece of crap. 1% of the time it becomes Best Item In Its Slot - the 14% cure potency with +1 refresh Fascia Bliaut turns a SMN from half a white mage to 3/4 of one.
Ya I was there for the augmenting stuff. Got a -1 STR +12 water on a Hagun... Hated that system.
