This question is also relevant to the magic hack for Technomancers of "Fabricate Arms", if you apply a technological augment/boost to a weapon or suit of armour (provided the total bulk is 10 or less) it is technically one item - does this mean an augmented suit of heavy armor can be fabricated in one use by Fabricate Arms?
For example, if I use Vesk Overplate I with the MedObserve Interface, Basic augment - does that make it a single level 6 suit of armor for the purpose of Fabricate Arms?
I feel this is directly relevant to the query above of how do you calculate the level of combined gear and whether it counts as a single items for game purposes?
