Some simple, one-use magic items for an upcoming weird west, 5e-ish campaign.
A wizard can study these charms as if they were scrolls for purposes of expanding their spellbook and add a normal version of the spell to it, but doing so consumes their magic as if they had been cast.
This pig-leather poke of 99 clinking discs of fool's gold can be used to cast friends once. The target of the spell will believe the discs to be gold coins for the duration, as well.
A pair of knucklebone dice, each wrapped in the end of a rawhide tether. If hung from the handle or wrapped around the body of a walking stick or staff, they can be used to cast shillelagh on it. When you do, the dice clatter against each other - roll 2d6. On anything less than a 7, they crumble.
An iron rail spike that looks like it just came out of the foundry, glowing with a soft red light, but strangely casting no warmth. Striking it with a hammer loudly ignites it to the brightness of a candle for a minute. Striking it again while it glows this way causes it to flare up to red-tinged light spell for an hour, after which it becomes an ordinary rail spike.
This snuff pouch is made of waxy reeds woven tightly together. Filled with herbs, it can be used to cast druidcraft once, but the effect always manifests accompanied by a sneeze.
In full, bright sunlight, this burnished tin hand mirror can be used to cast fire bolt with a 300' range, and then melt.
A handful of jagged, magnetized scrap-iron needles. Toss them into the air to cast wrathful smite, and they will hover around you. When you hit and trigger the spell, the needles fly out and pierce the target, giving them disadvantage on any save to end the frightened condition imposed by the spell.
A bent and reforged cavalry saber handle forms the grip of this oak walking stick. It can be used once to invoke the soldier's memories that infuse it, casting longstrider on the bearer and allowing them to use the stick as a saber for the duration.
This delicate yew dowsing wand trembles in the presence of blood, granting advantage on checks to follow a trail to the wounded, but casts healing word on its quarry and becomes nonmagical as soon as it comes within 60 feet.
Anyone proficient with a playing card set can use this deck of gold-gilt playing cards as if the spell was on their class list. These decks are becoming more common, everyone involved in a game where one is introduced can make an Arcana check to recognize it. As part of play, the owner of the deck can command one other player to lose the game (giving disadvantage on any checks for the game), or, sometimes more sinisterly, to win the game (giving advantage). At the end of the game, the gilt has worn off on the players' fingers, and the deck becomes a regular, non-magical deck of cards.
Several tiny glass vials of patent veterinary medicine. The labels make it unclear which are appropriate for which animals, but the smells are unmistakably alluring. When used to cast animal friendship, also roll a d6: On a 1, the target animal attacks immediately; On a 6, the effect is permanent.
A mycelium-riddled railway map points the way towards routes not yet established, and ones long since rotted. It can be used to cast pass without trace once, and fungus and slimes will eat the footsteps of those who follow its dampened paths. If cast in the desert it simply desicates.
Deep in this cheaply printed religious pamphlet for One Eyed Jack, a misalignment (?) of characters is actually a prayer of spider climb.
A finger ring of white salt, that doesn't melt despite humidity or sweat. You can eat it as a ration, or eat it to cast mirror image. If you're somewhere salty, attacks against the images have disadvantage.
This wallet of reeking cigars can be use to cast locate animals or plants - the smoke that drifts from them indicates the direction. Adding a bit of the quarry to the cigar will double the range.
Poems of loss and fidelity grace this embroidered linen hanky. It can be used to cast wind wall if fluttered as if in farewell, at which point the embroidery unravels and falls out.
A clockwork toy donkey that can happily stomp around and bray when wound up. Wound in a certain unintuitive combination, though, it brays... backwards? somehow? in a dissonance that replicates dispel magic. After this it continues its playful aspects, somehow looking more pleased with itself.
This pair of wooden hare statuettes is carefully (and demurely) interlocked. When teased apart, they crumble, and a stinking cloud effect of boisterous charging bunnies, dust, musk, and... scents erupts.
An old leather dog collar scratched with the name "Bo". It can be used to cast polymorph once, changing the subject into an shambly hound dog for the duration. Since only one form is available by using the item, the target has disadvantage on their saving throw.
A finely printed religious pamphlet for Factumus that can be used to cast staggering smite. If all the dice come up the same, the book is not expended in the casting.
An old, dry cardboard box tied with a faded black ribbon. Inside is a dried grave wreath. It can be used to cast seeming, but only to create the appearance of a funerary party with out-of-date fashions, with a duration of 24 hours, at which point a ghost appears and reacts as if it had observed its own funeral again.
