Especially with that reply, I have another question from the side of a non-mage. Or maybe really some questions.

First would be the use of magic in "normal" crafts, such as: Is it common for someone to improve their craft with magic either by unconsciously channeling some of it during production or through learning of explicit runes / enchanting procedures? Are magical items (lamps, storage ..) / weapons common at all or special as only trained sorcerers create them?

And how does magical affinity show for people not formerly trained? Are they aware of surrounding magic or is it just the general possibility to make use of it without any real implications?
