Item: Embalmed Hand With Wheels (3): mentally controlled by a magic-user, the drones deliver a lesser version of the Life Drain effect of the Wraith: 2d6 necrotic damage. The target must succeed on a DC 14 Constitution
saving throw or its hit point maximum is reduced by an amount equal to
the damage taken. This reduction lasts until the target finishes a Long Rest. The target dies if this effect reduces its hit point maximum to 0.
Although… playing as a ring that possesses the wearer would be a fun and interesting idea for a DnD character.
Item: cursed ring that possesses the character, but not as the evil warlock this trope usually winds up being associated with (roll d8)
just some random unlucky guy that got his soul stuck in a ring
a king/queen whose soul was removed from their body and put into the ring so the next in line for the throne could steal their body and rule
the character, but from a couple of years earlier, lacking all memory of the interceding times
a rust monster that can’t figure out how to eat metal without its feelers
a ring that can’t figure out how it wound up in a PC body and really just wants to be wrapped around someone’s finger
the ghost of a retired Big Bad that has been dead for years and is kind of upset at being called back from the World Beyond just because the heroes that defeated them forgot to destroy one of their horcruxes or whatever; keeps trying to kill the host body so they can go back to eternal sleep
an extraplanar body-tourist taking a vacation from the Swirling Realms to visit the quaint lands of mortals. Amused by local customs like having mass and the linear flow of time

Item: Auto Mephit; as the Steam Mephit, but replace all instances of the word “steam” with “car exhaust fumes”. When in physical contact with a vehicle, its upper speed limit is doubled.
Spell: Align Inventory, attunes all items a character currently has equipped to their alignment; does not affect items stowed away in pocket dimensions (Bags of Holding, Portable Holes, &c.)
