Hey all, I want to create magic items that are both extremely funny yet also useful. So far, I have a trident that deals extra fire damage on a hit (It's called the Trident of Grilling), but I'm struggling to come up with anything else. Ideas?

One of my favourite home brews that I stole from TikTok is The Hammer of Healing. It's a small mallet and you basically hit someone with it and it does 1D4 damage and at the same time does the same 1D4+1 healing. It's a ridiculously bad way to heal characters and yet out of combat it always seems to be my players first choice

My favorite to give to old wizards:

Robes of Flashing - Using a magic action, you can lift up the bottom of the robes, from inside the robes a bright light flashes causing blindess to creatures in a 30ft cone in front of you on a failed CON save.

I'd love to hear more of these! Hammer of Healing is brilliant.

Here are some magic items my dwarf shopkeeper with a speech impediment has

"Bagoffolding" (Bag of folding) Resembles a bag of holding, except that it is the size of a normal bag. Any objects placed inside are "folded". Clothes placed inside are folded neatly, scrolls inside are made into little origami swans, and anyone who reaches into the bag runs the risk of having their fingers bent backwards.

"Bagofoldin" (Bag of olding) Resembles a bag of holding, except that any object that is placed in the bag is aged 1d20 years for every day that it is left inside. leave some seeds inside? A tree may erupt from the bag at random. Put some wine in there? Aged to perfection. Keep in mind this only pertains to objects and plants and such.

Coobafforce (Cube of horse) Resembles a cube of force, but summons a horse as if by the find steed spell when any sides are pressed

Potion arrows.(consumable) They are arrows with potion bottles at the end that you need to shoot into peoples mouths. Target a willing creature then roll a d20 and on a 11 or higher you get it in their mouth giving them he effect of the potion with no damage, on a 10 or lower you shatter glass on their face  doing 1d4 damage as well as giving the effect of the potion. 

Hoola hoop of sanctuary. You can use it to cast sanctuary which  you do by spinning the hoola hoop around your waste. When the spell ends you drop the hoola hoop and you loos the ability to use a hoola hoop for the rest of the day (until the end of a long rest)

Card of spell reversing (consumable). Consumable,  when a spell targets you or an ally  casts counterspell with a dc based on rarity.  If they fail the save  you cast the same spell back at them using your attack and dc  but if they succeed they are compelled to say "no you" in which case the spell is redirected to you if it was targeting some one/ some where else. 

The god-tato. It makes people gods, but only if they deserve it (can use it at level 20; all other times, it just says "uh uh uh, you didn't say the magic word!").

Weapon of Opportune Embarrassment : when you roll a Nat 1 with this weapon it turns into a giant inflatable version of itself and makes and hillarious "boing" noise, casting Tasha's Hideous Laughter on the target of your attack (DC 15, no concentration required).

These might fall more under the "funny" category than "useful" but I think creative players will find ways to make use of them:

1. Figurine of Wondrous Power: Silver Raven, flawed.  It functions as described in the DM's Guide, except when using it to cast the Animal Messenger spell, the raven arrives at the target and caws frantically at them for about 1 minute, and departs.  The raven's calls have no meaning, and anyone using the Speak with Animals spell only hears frantic, incoherent screaming from it.

2. Talisman of Dragon Detection.  This polished skull has draconic runes carved into it and is hanging from an iron chain.  When a creature of "dragon" type approaches it within 100 feet, it screams loudly.

3. Immovable Rod, flawed.  It functions as described in the DM's Guide, but only if no creature is touching it.  If a creature touches it, it de-activates automatically, and it will not re-active while any creature is touching it.  (Note: "touching" includes handling it with gloves on.)

4. Scroll of Vitality, Goblin-made.  This scroll grants 3d4 temporary HP -- but not by reading it.  You have to eat it to gain the benefit.

5. Fermented Healing Potion: it can heal you... if you can keep it down.  Make a Constitution saving throw when you consume it.  If you succeed, you regain HP as expected.  If you fail, you lose your next turn because you're vomiting.

6. Distilling Waterskin:  any liquid left in this waterskin overnight becomes an alcoholic beverage- beer, mead, perry, sake, or other drink appropriate for the original contents, or the setting.

Tankard of inebriety: this appears to be a tankard of sobriety, but instead of preventing intoxication, it causes it, whatever the drink.

The Griffin's Saddlebags book that's just been added has some amazingly weird magic items. I think my favourite is the tiny Gelatinous Cube that just wanders round you house like a Roomba cleaning things up

Well, For my players (+ when I was a player) I made items such as "FORGIES" where they throw frogs at the enemy, I've made "Stick" which is a shiny stick that they can beat people with, One of my players asked if I could make an attack called "Eye Poke" which is self explanatory, I made "*BOOK* The Guin Saga" Which "147 volumes + 26 side-story Novels. Start reading the books, this takes forever. this makes your opponent go insane, and as you finish the series plus the side stories, your opponent’s head explodes" (that's the description), also made "Gaslighting" and "Frying Pan"  

(btw if you go to the homebrew collection and search for them, you'll find the items I've made) 

• Detective's glasses: goggles/glasses (change appearance/name at will; mine are steampunk-looking) that improve your sight close up, giving advantage on investigation checks closer than 3 feet.
• Self tying rope. Holding on to one end, throwing the other end at an object causes the rope to tie itself to the object. Using a command word causes it to loosen.
• Key that opens/locks any lock that is not magically warded.
• Magic beans that fill your belly, giving you a full day's worth of nourishment. Eating more than one causes you to regurgitate, wasting the bean(s) beyond the first.
• Jumping beans. Eat one and get triple jumping distance for 1 hour.
• Paint that lights up when you speak a command word.

Not mine, but my DM's. 

It finds its way into every campaign.  The "Dinner Plate".  Supplies one hearty meal of anything you want.  The meal gives you 1 day worth of food.  Everyone eating dried rations and you pull out a full plate of fried chicken, taters and veggies with bread.  My DM is big on watching rations and supplies.  Also when you rescue those kids who have not eaten you give them a good meal.  

Another one, was the mug that prevented "hang-overs"

Deer bottle of... healing?

More of a group joke than an actual magic item in one of my groups, that we came up with when one of us almost died after being stabbed with a dear bottle (and they had a dump stat of constitution because they were apparently not that confident, whatever that has to do with constitution?) . You essentially stab someone with a bottle shaped like a deer head, and they take 2d4 magical piercing damage and regain 2d4 HP. Sort of like the hammer of healing above except it's more of a gamble. One use for healing, but the stabby bit is reusable. 

My all time favorite magic item is called the Rock of Returning, in all appearances it is just a regular rock, however once it is touched by a player it becomes bound to them. after a nondescript amount of time, it reappears in their pocket showing no damage, (or you could make it useful as ammo and have it reappear right after it hits the ground.) it is fully destructible but that still doesn't stop it, it isn't a curse and it can't be dispelled, it is bonded to your soul. it weighs as much as a rock. have fun! I gave one of my players 3 of them.

the main use behind it is how the player handles it, they can enchant it, us it as a misdirect, or cast disguise object on it and try to sell it. its infinite ammo or a last-ditch attack against the bbeg.

I heard about a homebrew ring where it lets you change/remove/add a letter of a spell... forget what it's called though.

I created the The Clarkenters, primarily as a joke, but they do have some use cases. They're a pair of ordinary spectacles, but they have... side effects. The primary effect is that it's a "perfect" disguise as no one will realise who you are while wearing the glasses. The item is cursed though, so you can only take the glasses off during combat when no one is looking.

A few more of my creations, which might really fall into the "fun" category (define "fun"), but they are useful:

• Feather Blade - A dagger that you can recall to your hand when thrown, but it deals damage to creatures it flies through when flying back to your hand.
• Bottled Sunlight - A small sealed glass bottle with mysterious liquid inside. You can use your action to shake it to shed sunlight in a small radius. You can also throw it to blind all creatures in a radius.
• Frozen Heart - A shield that synergies with Protection and Interception fighting styles. If a creature within 5ft of you misses you or you reduce the damage dealt, you can use your reaction to cause cold damage to the attacker (or be used as part of the same reaction with Interception/Protection).
• Spell Reversal Armor - Once a day you can infuse it with a spell slot. When the wearer is hit by a spell that targets them and only them (and is of equal or lower level than used for infusion), they may use their reaction to rebound that spell back to the caster using the same attack and damage rolls and spell save DC. Once a spell has been rebound, it must be infused again with a spell slot.
• Sunglasses of Minor Fashion - sunglasses that gives the wearer immunity to sunlight sensitivity, but also negates darkvision. They also give advantage on saving throws against being blinded.

The flue of farting - when played makes a putrid smell dc 5 con check or run 5ft away 

Crossbow of misfire - fires backwards

Portal of return - travel through the portal realm for 1d10 minutes and return in the exact same place bonus points if it’s portable

The mug of alcoholics - makes you hungover

there is one that prevents hangovers but I’ll get the name later as I have the book with it at home

Potion of Fear of Cats: not useful to the party at first glance, but if you manage to get it into an enemy, suddenly your cat familiar is the scariest thing they've ever seen, not to mention if you have a tabaxi in their party.
