I need some creative, crazy, potentially unplayable deamon weapon effcts for my game. Go wild, Veeky Forums

It starts out as a normal weapon, but every time it's used it starts to mutate - growing fleshy outgrowths and metallic tumours and firing strange ammunition. Sometimes you can gear muttering inside.

A weapon that is no better than a common quality version, but the daemon still resides in it. It just complains non-stop about everything.

It shoots the burning, screaming skulls of the that explode on impact.

You need to reload it by using the alt-fire, which is a bear trap-like contraption attached to it like a bayonet, to behead foes.

The weapon is extremely powerful, but there's a 10% chance an injury dealt by the weapon is reflected into the wielder's body.

The first time the weapon is drawn, it shrieks and moans very softly.
Every time it takes a life, the weapon's screams become stronger and louder.

Whenever the weapon strikes something, its blade morphs into that material as soon as it leaves the target surface. This means that if it strikes soft flesh, it will become a mushy sword of flesh and blood.

The weapon is of a different size every time it is drawn from the hilt.

>weapon containing the bound souls of a psyker and a daemon, locked in an endless battle of wills. Casts random psychic powers on use (make the table yourself). 50-50 chance of it targeting yourself or the enemy. Psychic phenomena and perils of the warp can occur.

Demonic Blade that sings classical 50's ratpack classics whenever it's unsheathed. It's got a decent voice, but impossible to use for stealth.

Possessed Bolter that shouts BANG whenever it's fired. Will continue to do so even if it's out of ammo, leading to confusion as to if you are actually shooting or not.

Daemonic Flamer that fires rainbows and smoke clouds with happy faces on it.
WARNING: IT MAY SUMMON THE COWS. AND YOU ARE. NOT. PREPARED. FOR. THE. COWS.

Gun is in fact a rubic cube logic puzzle that cant take the form of various guns if you can solve it. Failure to solve it will cause it to try and eat you.

Sentient Demonic Maul possessed by the ghost of Terry Cruz. Smells amazing.

Demonic Spellbook that narrates itself. Does so in the voice of Gilbert Gottfried.

8 Foot long Butter Knife. Not possessed, but one day the original owner is going to come looking for it.

Some sort of Weaponised Grandfather Clock

A Giant Silver Bell that can cause people to explode if rung just right.

Wait a minute... these are just my Bloodborne 2 ideas now.

A book, that can speak and pretends to be omniscient. Doesn't ask for much, readily answers when spoken to but it just. won't. shut. up!

Even a simple, straight-forward question gets an hours-long answer delivered in a gentle, paternalistic if a bit sarcastic tone as the book dumps any tangentially relevant info it has on the subject. Anyone present at the moment the question is asked is forced to endure the entirety of the lecture, no matter how much they try to avoid it. The only way to make it shut up is to endure the whole babbling or kill the one who asked the question. Woe to the user if he dares ask an open-ended question....

A miniature ancient possessed battleship in a bottle. It fires the nova cannon (shell to scale) if you uncorck the bottle.
Yes I know Novas are Imperial Only.

A simple handgun that appears normal, and is loaded with normal ammunition.

But every time as bullet is fired from the gun the bullet changes into some random small living creature travelling at the same speed as the bullet was. One shot might be a heron, the next a racoon

Shield that can block any amount of damage infinitely, but you will then receive that damage 1 year later, including all effects.

Sword that adds the limbs you dismember from someone to your own body.

A short spear that, when used, makes the wielder see in the third person, top-down perspective
Potentially lethal to an untrained warrior, as all his senses become fucked up, but can grant total awareness of their surroundings to someone that trained enough with the weapon
Of course, switching back to first person is also a chore, inciting the warrior to constantly use the spear, and thus reinforcing the demon's grasp on their mind and soul

roll 1d1000 on a result of 001 OP turns straight

Off the top of my head.
Daemon Bolt Pistol that feeds off the user's blood, maybe from a tube or a tentacle with a lamprey mouth or something, and fires off daemon infused, frozen blood shards.

Pic unrelated

The demon boast to be a millenia old powerful weapon. Every cultists knows the legend and are afraid of it, so you get a bonus to Intimidation and Commanding.

In fact the demon was trapped in a ancient xeno "pellet gun" as a punishment. It's not very lethal, but can pop an eye if you are not careful. Also, warp tainted pellets under the skin can be dangerous on the long term

I really fucked up the grammar in this one.

User can take a wound to deal an extra wound to the target.

Reminds me of the Zamonian Grinzold & Dandelion sword.
A monster fighter and troll that got hit by a meteor. And their pulverized brains got mixed with the meteor metal and forged in a sword were both talk nonsense to the sword wielder.

>turns into what it strikes
>portal to oblivion
Sounds familiar.

>A possessed weapon which transforms itself of its own accord, making it hilariously hard to use unless it agrees with your actions.

>A sword that, if not swung in anger, will grow into the wearer's hand and slowly corrupt them, turning them into a daemonic monster.

>A blade who's sharpness is tied to the wielder's belief. The blade is only ever as capable as the wielder believes it is.

>A pistol that allows you to read the thoughts of those it kills, but only when the barrel is pressed to the forehead of the victim, and only when the victim is shot.

>The Sorcerer's handbook.

>It's a rather plain, unimpressive notebook. However it is actually an impressive warp artefact imbued with arcane energies. The pages in the book are filled with an assortment of various warp powers/spells and ripping out a page allows the reader to cast that power..
> The only caveat is that using more than 2 spells per day results in the book requiring a to be fed otherwise it will simply drain the Reader. Feeding the book is done by either making an individual with an equal or higher intelligence than the Reader read from the last page, or writing a page in an individual's blood.

> The casting for the powers is done using the bound demon's willpower stats.

> The default powers in the book are rather basic powers of the pyromancy, telepathy, and divination discipline. However by adding a page from someone with a high int score, a page will be generate with a more advanced power.

> Adding a page from a dumber person will result in the next power used periling.

The weapon's wielder feels no pain while it is drawn and has the might of a one man army.

After every 24 hours spent without killing something, the wielder experience the pain of all wounds taken or dealt prior to the that day at once

>>A blade who's sharpness is tied to the wielder's belief. The blade is only ever as capable as the wielder believes it is.
Can it pierce the heavens?

>listening to eurobeat ironically

holy shit actually kill yourself you fucking pussy

Hand it to the Pope, we'll see

Mist high-ranking priests don't have that much (if any) faith.

Yeah you're supposed to listen to eurobeat unironically.

The slaanesh go-go ray. A perverted and demonic neural shredder from a calidus assassin.

This weapon, instead of frying the targets nerves, reprograms them so the victim starts dancing. They will continue dancing until they die of dehydration, exhaustion, or cardio pulmonary failure. The only way to stop the effect is to shoot the victim again. Doing so causes great agony to the daemon, who may lash out at the user if it can.

a tzeentch possessed space marine bolter that shoots bullets made of the owner own soul

Crazy good, it ignores armor and burns the soul of enemies (bonus damage against psykers and demons).

When the owner shoots the equivalent of a full clip, it turns into a Rubric marine. If the owner is a psyker, it doubles the damage but burns out twice as fast

A slaaneshi bolter made in the same stuff/way of the Hellflayer.

It pierces both flesh AND soul, causing unreal and transcendental agonies if it hits (because your soul getting boltered down is not pleasant).

That's why you start determining who gets to be pope based on their ability to slice through solid stone with the faith-sword

A set of unbreakable manacles that can only hold those who have committed no crime

>1000 ft/s herons
sign me the fuck up

it rapes you

A person shot is not hurt phisicly, but gains memories of a loved one raping him.
These memories are very real and start replacing real memories to acomodate themselves, over any real memory.

the bullets hurt 15% more than regular bullets and deal 1,2% more damage.

The weapon is intelligent and has a boss Intimidation skill. DM doesnt have to describe how it intimidates you, he just rolls and say its devilry intimidation.
A person cant walk away from that without gaining permanent damage to some important stat or feature it has, bacause it is wicked like that.
It also can teleport.

The weapon can only be used by dr.phaustus like people and fucks them hard after a while being used or sometyhing.

OP said demonic, not efficient.

>A Bolter that shoots souls. It's not picky about what soul it shoots, so the user must get melee kills with the bayonet to feed the weapon or else risk turning their soul into a full magazine.

>A whipsword blessed by a Lord of Change. It functions like a Tyranid writhing tendril in that it has a mind of its own and can act for, or against the welder. Whether it whips away an unseen blade in a clever parry or become flaccid before the final blow is struck depends on the rapport it has with the user. The swordsman can improve their relationship with the weapon by telling it secrets, songs, and stories, but you can't tell it the same one twice (unless it requests it). Eventually the sword will become less like a petulant child demanding bed time tales and more of the users' Archivist, the wielder telling them stories of their past (and even present events if given enough bardic flair). One must be careful in parsing out tales and knowledge, as even at it's most congenial it will constantly seek out a better source.

>A Plasma weapon that is ABSOLUTELY addicted to Warpdust. It has an empty power cell well/outlet and instead has a gill like appendage that will greedily vacuum any narcotics close enough. The more it ingests the faster it shoots, to the point of essentially shooting a laser of pure plasma. It still Gets Hot, and screams in ecstasy while firing.

>At first this weapon appears to be no more that an ornate brass pike, but if one kills another with the weapon the skull of the slain victim will disappear from the corpse and reform at the top of the weapon, bound by thick iron chains. The Hammer will continue to accumulate skulls, increasing in size and damage (but not weight) until the Hammer has a head consisting of 88 skulls, which then it will be consumed by Warpfire and transport the user to Khorne's realm where the Daemon Smith that created the weapon takes it from them and rewards them with a weapon of their choice, forged from the corpse of a Juggernaut (which they must slay at the Forge). If the user dies before the 88 skulls or collected then the Hammer resets and the next user must use the headless haft from scratch.

>A flamer that shoots Bees. Plague Wasps, to be exact, thumb sized Daemons loaded to the antennae with flesh/metal/bone melting venoms. The fuel tank is actually the Wasp nest grown in and around a rotting Plaguebearer head. If one opens the mouth of the Plaguebearer (who is still alive and offers encouraging advice in droning, buzzing tones) they can feed it various materials/souls to nourish the Queen and change the abilities of the wasps given a few days. This can only be done three times or else the Queen will be overloaded and explode, unleashing the angry Wasps on whoever is unlucky enough to be around.

A Slaaneshi weapon that sucks your finger while you wield it.

Whenever it exists, the weapon starts asking "Where is Gulliman?" and saying shit like "Ultramarines are the best! Omega master race reporting in!". It is indestructible and can't be thrown away.

Everyone in the same universe where this weapon exists have a pee fetish and gets xp penalty for not roleplaying.
Is this what you want, OP?

The daemon in the weapon called the boner that talks to you and offers helpful advice, occasionally talking about all the daemon hunnies it's been with.

It can turn into a large weapon that must be held at crotch level and in order to fire it you must thrust your hips while saying something about the big boner.

A deamonic plasma gun that never overheats and will never explode.

The downside? It will slowly fuse with your arm and start growing additional plasma guns from your body. It will also fuse any piece of armor or clothing you have with your flesh and itself. Not to mention that the gun is inhabited by the souls of those that were slain by it and those who died wielding it. They all bicker at each other, complain, comment and more to the point that you start to wonder what made you pick up this gun.

Other downside. It makes it difficult to hide and move with so many plasma guns growing out of your body. The plasma guns also don't share the weapon's traits, so they can overheat and/or explode.

Your genitals also change into a plasma gun. Be careful while using the restroom.

Rictus, a sword crafted for a noise marine champion
Every blow, even slashes in air, produces a chorus of the most aggressive sounds imaginable (think nailgun on sheet metal + fork on plate + chalk on blackboard)
The noise is so awful that the feeling that settles around the teeth doesn't stop there
When exposed too much to it, teeth start getting loose and falling out, inflicting excruciating pain
Of course, the demon makes the bearer's teeth grow back, sharper, more crooked and more ingrown everytime
When the wielder bites someone, they remain embedded in the flesh, vibrating and burrowing deeper with every sound the blade makes

It's a powerful weapon, but the wielder will feel the pain of any wound it inflicts.

Satan quints make it canon

>make it CANON
I see what you did there

Nunchucks of Tzeentch

Repeatedly smack the user in the face.

>The weapon superficially resembles an ornate, archaic lasgun seemingly constructed of nothing but dark, sullen glass with tarnished metal details. The weapon feasts on memories, and isn't picky on which. If the daemon is not powerful enough to fire, it will devour memories from the wielder until it can devour the mind of a victim instead. Eventually, the wielder will remember nothing but wielding the rifle, and will be lost in their own head, only living through the memories the daemon feeds them.
Resolve as a standard Lasgun with the following changes: +4 damage, does its full damage to the Intelligence and Willpower Characteristics instead of Wounds (roll separately), ignores armour and Toughness bonus. Reload becomes "-" and Clip becomes "Special". Loses Variable Setting rule.
Starts with 2d5 shots in the mag when first aquired, and can hold an indefinite amount as max. Recharges 1 shot for every 22 Characteristic damage (Willpower and Intelligence) caused. Victims reach 0 Willpower or Intelligence instead fall into a vegetable state and dies of thirst or starvation unless attended. This is permanent, barring miracles (burnt Fate Point, at GM's discretion).
There is no telling the remaining ammo in the weapon beyond a subtle "glow". Firing it with an empty clip, the wielder immediately suffers 1d5 Intelligence and Willpower damage. Use of the weapon is Addictive (see rules on Addiction), and the addiction can obviously not be cleared with medicinal means. If the user is Addicted and suffers Intelligence and Willpower damage from firing when "empty", they must immediately also make an +30 Test against both Intelligence and Willpower, or that damage becomes permanent. Reaching 0 Intelligence or Willpower causes the daemon to take over as per Possession.

Nunchucks of Malal

Repeatedly smack the user in the nuts

a bo-staff that, when it hits an enemy, just wraps around that part of the arm and doesn't release this shape unless stroked, become erect once more.

When used to choke someone, the person being choked will begin to talk in a strange ancient language. when translated is just the recipe for cosmic brownie shake

Did this comic ever continue?
The author kinda fell of the deep end last I followed it. I'm hoping he is at least okay.

Give it to a complete dumb ass & lie to him about whatever you want to happen

We'll, I had a fun one. A ork power-male that was huge size (I think that's one size up from hulking) and requires additional cybernetics to field, possessed by a fleshhound of khorne.

It was a slavering, snapping weapon that track psykers by "scent" and had its own perception score.

It was responsible for many many dead nurglites.

>I swear I only listen to Eurobeat ironically

What a tool, I've been listening to nothing but Italo Disco for the last six months.

a sword that draws power from past battle that has been fought in where there fighting now, the more violent and bloody the battle was the more the sword yearns to fight

A Stradivarius cursed to only play anime, video game, and top40 music.

A broken sword hilt. Every time you stab it into something that has blood a chunk of the blade regrows made out of hardened blood. Every kill adds to the blade, EVERY KILL. Eventually we're talking dragonslayer levels of size and damage.
Problem: when the battle ends and the blood stops flowing, it returns to its original form.
Praise Khorne!

Solution: never stop killing

>Solution: never stop killing
Problem: when it gets too unwieldy to be effectively used. Even if a character has the physical strength use a sword 8X their height you're going to have to find the space to use it effectively.

It sucks your dick
Forever
It never stops
You can't use it as a weapon, it's stuck on your dick

Solution: install it on the chariot ot a tank and drive-by people with it. If it get too big for that install it on a titan. Then as a ram on the space ship.

If you happen to be a female or a member of species that don't have dicks (ork, kroot) you grow one the moment you pick this weapon.

Praise slanesh

>You can't use it as a weapon, it's stuck on your dick
You cant fuck someone else with it. After all as a daemon weapon it's almost indestructible and can punch trough anything - imagine blowing holes in tanks with a thing stuck on your dick.

It is a daemon weapon, why would it need to cooperate with physical laws and not the concept of greater and greater slaughter?

a fair point.
it's just that eventually, you will run out of people to kill.

At that point, you'd better have depopulated a hive city or so.

Blood for the Blood God Indeed.

>implying Eurobeat is only ironically good

It's like you don't even step on the Gas, Gas, Gas.

Double damage to pots and pans.

>potentially unplayable demon weapon effects

I've been messing with the idea of a bow that's just fucking impossible to draw back. Absolutely massive bows - essentially ballistas that are only supposed to be used by a single person. You jab one end into the ground and try draw the bow will all the might you can muster and even moreso. It's highly likely you'll break limbs and dislocate them in even the first use - assuming you manage to draw it in the first place.

If you do manage to draw the bow and load the arrow, you've then got to aim and finally fire the bow. But with your body absolutely ruined you'll almost definitely miss and the shockwaves from the bowstring snapping shut will fuck everything in a 10 foot radius - bowling you over and potentially sending people around you flying.

I mainly thought of this bow as a joke, the idea of using all your energy and body weight just to draw the bow sounded funny to me.
