I find myself looking for and modifying a new list of magic items to use in my 5th edition game to give an interesting twist to the game, so I just started looking for several entries suggested by google, I hope you find the items I was gathering for my game interesting:
Alien creatures from the astral plane have left forgotten along millenniums different artifacts and items that less advanced cultures in their technical level, use in the way they can imagine.
Green Wand: Made of material with a neon glow, when a creature is hurt by the staff, the creature damaged by the staff will flatly refuse to harm the owner of the staff for 1d4 rounds.
Purple Mask: Plastic and with a strong smell of dust. When placed on the face of a humanoid creature, it will have to resist to avoid the effect of a domination spell, if it manages to resist, it suffers a type of madness permanently. Single use.
Duplicate Chest: Small opaque glass chest that can duplicate any object stored inside it. Fading out the first object and delivering two copies of lower quality.
Red Horn: Red bone in the shape of a horn, when stuck on the user's forehead, it obtains a strength of 20 during 1d4 turns, it can be used once a day.
Dehydrated Aberration: Monster of CR 5 or smaller that fits in the pocket and needs 3 gallons of water to grow and fight according to its master's orders. It remains active for 3 hours before it is turned into dust.
Purple Pill: Single use, when consumed the pill obtains the effects of rage for 1 minute.
Control 9: Machine with nine buttons and a lever, pressing the buttons does not generate anything, just pulling the lever, generates an earthquake in the region for 1d10 minutes. One use.
Body map: Plastic roll, with different inks marking the veins. By placing a drop of blood on the map, changes can be made to the image, as if it were a voodoo doll.
Chaos Plastic: Green and rubbery, it is located inside a glass jar and can be extended up to 5 feet by 5 feet. The area in which the plastic was placed disappears.
Breeding Backpack: Bizarre creature inside a bottle with liquid, which can be carried on the back. When the character fails a saving throw of some magic effect or curse, the creature in the bottle absorbs all the damage or effect automatically and immediately is petrified.
Mini Automata: As big as a bottle, it has the shape of a jewel, but with a silver color, a small servant emerges who can serve as an explorer, but has a pitiful defense and life.
Pocket Laser: Metal tube with a golden button on one of its edges, when pressed it loops a radiant beam that does 1d20 of damage, if you get 1 in the roll, the object explodes.
The 3 Vials: Small box with a vial full of red, green and black liquid. Consuming only one has no effect, the liquids are tasteless. They have three effects according to the order in which they are consumed. Red, Black, Green... the creature is reduced to a black tar-like paste. Black, Red, Green revives the creature, as long as it is less than 3 days old. Green, Red, Black recovers total hit points. Other combinations have no effect. One use.
