Maybe a silly question, but I seriously can’t find this info anywhere. Where can I find the blueprint for the living armor component? I think I’ve checked all of the different faction’s quartermasters…is it just a random drop?
Afraid so. 
Hit up some heroes/nemeses/roguelike dungeons and hope you get lucky.
Damn. Thanks for the info, though!
Crucible is the fastest way, just Aspirant and the bonus retires should be enough to get all the low tier blueprints
