Here's a list that I made with Augment names, the stats they increase, the skill/level required to use them, and the prefix it puts on the gear.
Google Doc Augment List
*NOTE: The increased stat number varies on item slot. Legs might have stat increased by 4, but shoulders stat is only increased by 3. Item level of the gear doesn't seem to matter, lvl 50 gloves and lvl 32 gloves had stat increased by 4.
A separate table MIGHT be done in the future to show how augments effect each item slot.
