Mahogany Desk of Spectral Administration - This imposingly plain desk fills the viewer with the sort of dread one feels when facing down a hostile bureaucracy. A person seated behind it can send out a mental summons for any low level ghosts within a hundred miles to instantly appear before the desk one at a time and deliver their name, date of birth, place of birth, date of death, place of death, cause of death, names and last known locations of surviving kin, occupation in life, and occupation in death (that is, the nature of their haunting).

Ghosts can attempt to resist the summons, but failure results in full disclosure. If a ghost is normally bound to a certain location they are allowed to leave it until their accounting is finished. Cause of death does not mean a murderer's identity will be revealed, only that the ghost was murdered. The desk's user doesn't need to know beforehand who they are summoning or even if any ghosts are out there.

A person seated behind the desk cannot be harmed by ghosts but cannot perform hostile actions against them either.

The Hat of the Increasingly Agitated Beaver: A beaver-fur hat that allows the wearer to lift greater and greater weights of wood the angrier they get. This strength bonus only applies to wood and wooden objects. Continued ue of thi item make the bearer's front 2 teeth gradually increase in length

Belt of Youthful Japes - The buckle of this rubber belt is shaped like a winking geezer's face. If the wearer has suffered physical or mental deterioration due to age the belt restores everything but their appearance to a youthful state, but only if they are currently planning or carrying out a prank of some sort. Every 100th prank performed while wearing the belt adds a month to the wearer's natural lifespan.

Wand of Rarity - This tacky jewel-encrusted wand is tipped with a large golden 'R'. If it is pointed at a creature or object the wielder has an immediate but only approximate sense of how rare that type of creature or object is in the world. The parameters can be mentally adjusted, revealing how rare the thing is in a region or galaxy for instance. The notion of rarity can be relative of course, and the wand will adapt the impression it provides to what its wielder is intellectually capable of understanding.

Texeiran Jumping Beam - This heavy wooden beam was one part of a magical flying chateau, but the whole thing crashed and mostly burned up. The beam and others like it were salvaged for later re-use in other, more mundane structures, but their magic didn't fade away as expected, and they had a habit of suddenly "jumping" out of support structures and through walls at random, usually with catastrophic results.

Most of the beams have since been tossed into the wilderness, where they sometimes startle explorers whose magical items trigger "jumping spasms" through their proximity.

Ma Doqua's Stuffed Raven - This is a poorly taxidermized raven with an awkwardly outstretched wing and googly eyes. Despite its quality, some magic ensures no one ever throws it away.

Anyone trying to produce something artistic within 100 feet of it will unknowingly and inexorably be drawn to tragic themes. Writers will produce tear-jerker stories, painters will create images of utter gloom, singers will select the most despairing tunes in their repertoire, etc.

It's important to note that only the artistic output will be affected; the raven has no influence over a person's actual mood.

Amulet of Psychotic Emphasis - Any time the words "kill", "death", "murder", "slay", or "die" are uttered within 30 feet of the amulet, their volume and emotional intensity are amplified to an embarrassing degree.

Portable Toilet Slime
A domesticated slime residing in a collapsible box of holding. It waits patiently to be fed organic matter, to be digested quite slower than average slimes. The box collapses to about the size of an Octavo sized book. Comes with a book slipcover which is a collapsible privacy screen.

Sandals of Soft Trails – Everywhere the wearer's feet land, vibrant grass and flowers sprout for a minute before fading away.

Glass Eye Wallet – If the pupil of this high quality glass eye is tapped twice, a drawer just large enough for a coin springs out of it. The drawer is actually an extra dimensional space that can contain up to 1000 individual coins. If the person reaching into the drawer knows what specific coins are in it, they can pull out whichever one they want.

Cloak of Perfect Comfort: The enchantment on this cloak allows the wearer to be perfectly comfortable in any climate, temperature or weather, e.g. if in the arctic or desert the wearer will feel like it's a fine spring day in a temperate region, or if it's raining like dry. Requires attunement. This type of enchantment can be placed on any type of clothing or blanket, bedroll or etcetera.

Pendant of Sculpting - This rather heavy pendant is shaped like an egg with a strange saw-like pattern zig-zagging across its dull metal surface. It can be opened to reveal a small compartment inside, about a cubic-inch.

If a stone or piece of wood is inserted into the compartment, the pendant will gradually carve it into a small statue over about 8 hours. This will only work if the pendant is actually being worn by a living creature, and opening the compartment early ruins the sculpture. During the process the pendant produces a low buzzing sound. Each sculpture is unique, and can be abstract or representational.

The pendant is secretly powered by the wearer's life-force, resulting in an increased appetite and slightly reduced lifespan.

Ingenious players find ways to make almost any magic item useful.  In one of my current campaigns, a magic-user got a "magician's hat", which is a hat that lets them pull a single rabbit per day out of it.  I figured at most, it would mean they'd have to worry a little less about rations.  But you wouldn't believe all the shit they've managed to come up with using that damned rabbit (for starters, the poor rabbits have been frequent first-test subjects for potential dungeon traps).

Trap Chickens have routinely been a staple in dungeon-focused campaigns I've been in. I absolutely believe a "free rabbit a day" item would get used similarly. In fact, I should make a magical version where you'd want to go back and retrieve your trap chicken.

The Rubber Chicken
Indestructible
This is a rubber toy in the shape of a flattened chicken. Activated by blowing air through the rubber chicken beak, turns into a live chicken for 1 minute that can take simple commands like a trained dog. The live chicken can be destroyed, upon so the Rubber Chicken reappears and hovers where the chicken was last "alive." An indestructible magic object subjected to annihilation magic negates both magics — and causes a great explosion (GM determines).
