The answer, as always with dungeons & dragons, is naughty word magic. Need a workshop, assistance, and a master Craftsman? Okay, cast magnificent mansion, animate objects and conjure up the soul of a long dead armorer and bind him to your service. Problem naughty word solved.There is a fundamental conflict in what people think crafting should be. There is simulationist - full plate requires a well equipped workshop, assistants, months of work and a full time professional master craftsman with at least 10 years experience. Or there is the gamist approach, as seen in 3rd edition and many video games. Full plate can be created by an adventurer in the field with a work bench, four iron ingots, and an at most one days work.
I don’t really see a way to thread the needle between the two.
