There are two levels.I just want to double-check, because I read the Fandom wiki page on Guardian weapons but I'm not sure that's always reliable - you need one Guardian weapon blueprint for each weapon, right? So four slots = four blueprints?
I'd like to try out a similar build, but no way am I putting that amount of work in for something I might not even use again![]()
You need to unlock only once for the first round of guardian weapons. Once for each type. Unlock and buy forever.
For the salvation variants, you have to unlock for each one you want to purchase.
