[ And I'm not exactly sure what you mean by 'export the armor from the illusionist place in Candlekeep.
In the group combat training house. There's a unbreakable chainmail and plate with the illusion party. But you have to export the character to get it. They are armors with a l in the beginig of the file name (lCHAN01).
Just the few that are bg1 gameplay specific, like: Reveal maps, add containers, exotic items, items stack, npc class alterations, etc..
The "Breakable Nonmagical Armor, Helms, and Shields" component would be a nice solution to the equipament shattering discussion, but that's up to Ascension.
