So, there are several pieces of armor that have an inherent stat bonus. For instance:
Robe of the Arch Magi: Res +2
Circlet: Int +3
Shadow Weave: Agi +2
...
etc.
Are these considered an enchantment (i.e. do they take up an enchantment slot), or just part of the armor's inherent properties?
Also, if you were to enchant the items with that particular stat, is there a limit of +5 in total for that stat (so a circlet could only be enchanted with a further +2 Int), or +5 on top of the automatic bonus?
