It would be nice to, also, be able to "disassemble" the things you build. If you have the schematic, then you could "disassemble" things, like a pyro ax, and get the parts that made it a pyro ax back.
I don't consider it a good idea. After all you strongly modified what you had to get given object assembled. Perhaps it should be allowable with some simpler items (like flintlock pistol) in more mechanical disciplines. In a discipline like herbology you shouldn't expect it to work. Also in a discipline like smithy you it would work out to a very limited extent. For example you couldn't dissasamble pure ore. There should be also penalty included (so that you wouldn't get "fresh" ingredients. For example you dismount Pyro Axe. You should get:
- oak handle with slightly lowered durability
- pyro axe blade (you shouldn't really expect to get featherwight axe blade since you modified it so much)
Anyway I don't see much use for such a feature to back introduction. What would be the aim for disassembling things?
