its more a question than an issue:
How does FirstAid handle Apotheosis Affixes? Theyre adding flat amounts of e.g. Armor and Armor Toughness which doesnt get converted into local armor/toughness. Do these global attributes work? or are they just invalid and get ignored (in this case i'd wish for an integration of apotheosis into FirstAid's System).

Any armor you have that is not locational armor (be it in an item, an effect or something else) will be distributed on all armor regions.

Closing as answered
