Well Maka, this comes from Casters Realm...
Type 1 - Single stat enhancements (self explaining)
Type 2 - Multiple stat enhancements (also self explaining)
Type 3 - Worn Effects (such as haste, regeneration, etc.)
Type 4 - Weapon Procs
Type 5 - Single Weapon Damage additions (single changes to a weapon's damage I am thinking from what they said)
Type 6 - Multiple Weapon Damage additions (same as 5, but giving multiple types of damage, perhaps affecting delay as well?)
Type 7 - Here's The one that I don't know... and i've been looking everywhere, but can't find it. sorry
Type 8 - Plane of Time Items Only (well, it's augments for plane of time items only...)
Hoped this helped... also, if anyone discovers/knows what type 7 is, it would be a great help to get the information.
