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?

Yes, people can use magic in crafting. You might find blades inscribed with runes or enchanted with magic reagents, though (as to answer your second question), they are harder to come across. An adventurer might have an enchanted blade or a battle hardened paladin might wear holy-infused armor, but the average person won't have some sort of magical gear (unless you're a high elf, of course, since they're more inclined to use magic themselves). You wouldn't see guards up and walking around with [url=https://www.youtube.com/watch?v=KcOGxTCUZD4][Thunderfury, Blessed Blade of the Windseeker][/url].

As for the magic affinity question, high elf research has found that everyone has some sort of magical prowess that acts not unlike an essence. In other words, magic affinity is like blood that one uses to power/cast their spells, but can also be drained through the use of certain spells that devour the target's mana reserves, leaving them empty until they can replenish. One must go to school (or a church/temple in the case of religious-based magic) to learn how to physically harness their powers, but those with a stronger affinity generally have an easier time pursuing magic, with some colleges preferring those with a greater affinity to magic than those with weak ties.
