Regular tabletop role playing magic, however, is mostly focused on what might be useful to, y'know, an adventuring party. While that is useful to the players, you'd think that in a world with magic people would come up with relatively mundane, day-to-day uses for it. Because what good is magic to a farmer if it doesn't help with the harvest? What is good for a merchant if it doesn't help her make a profit or balance the books?
So here's some more everyday uses of magic, many of which conveniently duplicate things we've achieved via technology (i.e. we know they're actually useful). I guess the list could be looked at as a background detail generator table or some such - if you squint hard enough, that is.
- Legal documents sealed/signed with drop of blood. Magic can then be used to verify identities of the relevant persons. Anyone who works with paperwork carries a special needle for drawing blood together with writing implements.
- Enchanted ledgers that total up income and expenses on their own and are capable of updating them. (Sort of like magical spreadsheet apps. Only inkier.)
- Harvest-mages wander the rural countryside looking for work. They mostly only knows spells that speed up harvest, such as Beltor's Fruit Shaker or Greater Wheat Reaper. They get a lot of call in wartime, when being able to bring in the harvest quick and with few people is important.
- Mages specialising in pest control. Rats routed, bedbugs banished, termites terminated - or your silver back! Gives me ideas for wizards in coveralls.
- Credit-enchanted items - work like our credit cards, but on magic, rather than technology. Come to think about it, if I were a wizard in a fantasy setting, banking in general would seem like a field that could benefit from magical expertise.
- Pay crystal balls for contacting home when you're away.
- Spells for copying texts from one sheet to another. Who needs printing again?
- Magically-powered keywords allow accessing relevant chapters of a book quickly. Useful in big manuals, encyclopedias and reference books.
