Ring of attunement: allows one additional item to be attuned for the player (requires attunement)
This is actually really strong for a max level artificer as they get a +1 to all saves for each attunement
Ring of Luck.
Note this is not Ring of Good Luck.
Implement it as you wish. I currently flip a coin at the start of each day, and depending of that, it’s good or back luck for the day. Never communicate which, let the player using the ring find out.
One of my players really enjoys his Cloak of Billowing
A bench which increases your intelligence to 30 so long as you’re sitting on it. It isnt so heavy that it can’t be picked up, but it is quite cumbersome
Thinking Stool
I always try to have 2 Immovable Rods with my character so I basically have an infinite ladder. You can lock and unlock each rod and use them like rungs to climb things, cross gaps, etc. And they’re not really rare or expensive.
Maybe add the opposite of those; rods that never stop moving. Unstoppable Rods.
Boots of blinding speed.
Reference, in case you’re not an old.
An idol that periodically tells the current time of the day in a loud and clear voice. But only at night (or when the party likes to sneak).
I gotta say, that’s a pretty good useless item
The vibrator of slicing.
This is a knife with two saw-like blades that move back and forth, allowing enhanced slicing of cooked or raw meats.
It gives advantage on all intimidate checks, with a +2 if wearing fishnets and/or high heels
