Since its inception, the Dungeons & Dragons game has kept magic items firmly in the realm of those things which are of direct use to adventurers. Weapons, miscellaneous items, magic rings and wands, etc.; all provide some benefit in combat, or are otherwise useful in an adventuring setting (with notable exceptions such as the spoon of stirring…).
However, given a world in which magic does exist, it stands to reason that such would be used for more mundane purposes far more often than to assist adventurers in, say, discovering the location of secret doors. One has only to look at the “real world” magical grimoires and Black Books with their spells for curing impotency, discovering the identity of one’s future husband, etc. to see that such practical magic was of much more immediate interest to those who practice the art, presumably because they could be paid for it more often than for more esoteric and exotic applications.
Where this leaves us, in game terms, is a class of magic items that are of little direct use to adventurers save as treasure to be sold for coin. As such, the can be thought of as belonging to the same class as tapestries, statues, jewelry, and the like. The mere fact that they are magical in nature doesn’t imply a “high magic” setting; indeed, in a low-magic setting one might expect to see more of this sort of magical item; scarce magical resources would be used in ways that would most practically benefit the practitioner.
So here I present a sampling of such items, which are magic items intended only for sale, rather than the direct use of the adventurers. Of course, adventurers being what they are, they might well find some creative use for such things in the course of their quests, but at the end of the day these creations are intended for the use of non-adventurers. Often a village will collectively own one of these implements, lending it out to villagers as needed. Command words, if present, are usually engraved in an inconspicuous place on the item.
Anvil of Striking: Metal worked on this enchanted anvil will be harder and stronger than normal, and yet easier to work while it is still hot. It is worth 1,000 g.p.
Barrel of the Gods: This large oaken barrel will always produce a superior vintage of wine, when aged in this barrel. Up to 60 gallons can be aged in such a barrel. It is worth 750 g.p.
Broom of Sweeping: This item appears to be similar to any sort of enchanted broom. When the command word is spoken, however, it will begin sweeping the floor of whatever space it is in, in a 10′ radius. If a door is present within 30′, it will sweep towards that portal (the nearest one, if more than one door is present). It is worth 500 g.p.
Chest of Cooling: Seemingly an ordinary chest, this device will keep whatever is within it at a constant temperature of 40 degrees Fahrenheit, allowing food to be stored for much longer periods than is usually possible. A small chest is worth 750 g.p., while a large chest is worth 1,500 g.p.
Golden Spindle: Fiber spun on this enchanted spindle will be twice as strong as ordinary string or thread. It is worth 500 g.p.
Jug of Fine Brew: When used to brew ale or mead, this covered jug will always produce a superior-tasting beverage, and will never not ferment. It is worth 750 g.p.
Millstone of Productivity: Allows grain to be milled 50% faster than an ordinary millstone. It is worth 1,000 g.p.
Playing Board: This appears to be an ordinary board with a design on it for playing Nine Men’s Morris, and appropriate black and white stones will be found with it. When the command word is spoken, the board will play the game against an opponent. It is not a perfect player; roll 1d6 for the player and 1d6 for the board, adding the appropriate INT score. The highest total wins the game.A board that can defeat someone with an INT of 6 is worth 100 g.p., one that can defeat an INT of 8 is worth 150 g.p., one that can defeat an INT of 10 is worth 200 g.p., and so on, but fancier boards made of precious substances are not unknown and could command great prices. Boards capable of playing other, more complex, games are obviously worth considerably more.
Plough of Mighty Furrowing: Cuts through the toughest sod with ease; a team of horses or oxen can plough a patch of ground in half the time it would normally take. It is worth 1,000 g.p.
Vermin-stone: This enchanted stone will cause bedbugs, cockroaches, weevils, mice, etc. to flee from its vicinity, with a 20′ radius of effect. Magical vermin, creatures with an intelligence of semi- or higher, creatures under magical control, or monsters (including giant rats) are not affected. It is worth 1,000 g.p.
