Fun fact : introducing a species to an environment with the intent to cause harm counts as biological warfare! Which is a war crime under the Geneva conventions!
Got two here, one from my time as a dm and one as a player:
1: the party interrogated a celebrity bard in his dreams because they wanted answers and he was too far away to talk to. Later, they also held him against his will dancing in a parlor while still invading his mind.
2: the party’s monk (me) and the Druid essentially performed an ear piercing, nose piercing, lobotomy, and all around tortured a chimeric hybrid creature because we could not for the life of us kill it in combat.
So to face one of the big bads we needed to get into the inner city and in the party only me and 1 other player out of the 5 have survived up to that point. So since they only knew us 2 the other 3 casually walked towards the inner city while me and the other player went to the other side of the city and caused chaos. Due to some weird BS I had a tlexolotl as a familiar which allowed us to make infinite bottles of fireball. So me and the other player started bombing the city and due to the commotion all of the guards of the city rushed towards us (they were robots) so we ended up killing over 150 guards and burning down the whole city.
My friend, has a sorcerer character that’s literally just a ceramic garden gnome that has a magic bucket of popcorn that doesn’t run out. Let’s just say he traumatized our DM by suffocating a bandit by cramming an ungodly amount of popcorn down his throat
Not sure if this counts?
My Tiefling Warbard has repeatedly killed fleeing enemies on the basis of "No witnesses so their boss don't know it was us" or "They may bring reinforcements".
Also when threatened by a smugglers ship she warned them to back off, they didn't so she set it on fire.
Our druid keeps bbqing the enemy wildlife with moonbeam, in particular I feel really sorry to the poor owl bear, in a ruined temple.
So if your curious: stacking surrendering opponents is a war crime not sure about retreating ones
Also fire against militant targets is NOT a war crime under the Geneva conventions as far as I know
We lured a giant fire centipede abomination the size of a mountain into the the no-man's land between two armies so that they would help us kill it if only to save their own lives.
We then proceeded to sacrifice all of our unused magical items and minor artifacts into a ritual spell so that the summoner could Rita Repulsa her eidolon, the proceeded to have a kaiju battle while she rode on the deck of an airship cackling like a madwoman.
The fight between the Imoleth Xoltani and the Galactic Allbuncle, the amassed armies of Holwich and Galone, and the avatars of the gods resulted in hundreds of thousands of deaths.
The surviving armies started spreading word of the Allbuncle and supposedly teaching the summoning arts, earning Aoife that worship she needed to eventually become a deity, and Winter, who lured the Xoltani, got escorted off to Holwich to stand trial for a completely different war crime that is definitely against the Geneva Convention.
We did the thing Thanos does in Avengers Infinity War and used 50 Scrolls of the Comet to basically drop a planet on a group of Enemies.
We also summoned a black hole.
Oh, I know this one!
I had a wizard who was highly adaptable and particularly creative with his magic, to the point where he got bitten by a werewolf at one point and thought, "How the hell is this a *curse?* This is cool! I get to become a wolf, I can be immune to most forms of physical damage, and I get claws, all without the use of magic? This is awesome!"
So when you tell him, "Get information out of this guy, I don't care what methods you use." you just know it's not gonna end well.
I don't know if this one is on the geneva convention, but when interrogating someone, he cast Contagion on them to give them Flesh Rot and blew their legs off section by section with Eldritch Blast.
Yes that is tourture and biological warfare
Both of which are war crimes under the Geneva conventions
Also interesting note: the DM manual specifically recommends not letting PCs tourture during interrogations
My party was coming off of an intense fight for the soul of the Cleric, lost thanks to the Deck of Many Things. They were on their way to a meet Titiania, who was now perturbed by their delay. After she scolded them and refocused them on their mission to find a missing McGuffin, they needed to release some tension.
While flying across the Summer realm of the Feywild, they saw a group of poachers chasing a mama Owlbear and her cub. The Warlock-Cleric, who was flying on a conspiracy of Ravens (16 in total), decided to carpet bomb one of them with Raven poop. He crit, so I let the player roll all the dice in his tray for damage. A couple hundred or so HP entombed the bad guy and his horse. Then the Ranger commanded her giant flying Mammoth to do the same to the others. I also let her roll all her dice for damage, and they were encased in 423HP of flying Mammoth dung. One poacher remained unglooped, so the Cleric & Druid, who were riding on a Giant Eagle, picked him up, flew him up as high as they could, and dropped him. He took 20D6 damage and was instantly indistinguishable from the guano.
Poop jokes aren't normally our style but this was so great, and just what we needed to shake off the stress of the previous in-game day.
After rescuing 2 kid from a hag's tower one of them irritated the human necromancer enough for him to grab his sword and slice the child, after realizing what he did he used animate dead to reanimate the child and give the child back to their parents. He was given a handsome reward in gold and ran out of town asap.
Glassed a vast section of a desert planet. All to escape a small party of Astral elves that had shot down their ship in a Spelljammer campaign.
The group has a Barbarian Minotaur, Harengon Gunslinger, Plasmoid Artificer, Tiefling Wizard, Half Elf hexblade, Dhampir Samurai fighter (he was a pirate) and a simic hybrid ranger (moth man).
Long story. But shortest I can make it with enough context.
The group has a unique spelljammer, a steampunky rocket/submarine named The SunSeeker. It has a reactor onboard you can sacrafice magic items too to give it spell slots the pilot can use.
The ship was shot down by Astral elves, intact but "knocked out". A bunch of elves rode out to go investigate the ship. The group PANICKED. Dumping magic items into the reactor to start it back up.
The wizard grabbed a suit of armor, a relic of a homebrew race called the Heliokin. The armor was blessed by their goddess and infused with Hellfire/Sunfire. The group had planned to return this armor to the heliokin, but the wizard in their desperation tossed this artifact into the reactor. The reactor broke down the armor, and I as the DM had to pause and figure out wtf would happen. The mechanics were only designed for uncommon, up to Very rare (purple) items.
I had it that the ship's reactor was soon filled with uncontrolable Hellfire/Sunfire. The engine erupted flames and incinerated the on coming astral elves as the ship took off. Corkscrewing through the air uncontrolled. The crew held on for dear life, the pirate samurai fighter and the gunslinger crawled to the controls and grabbed the manual controls to try and control the ship. The wizard jumped in the spelljammer helm, finding the entire ships systems bathed in this powerful Hellfire/sunfire.
They angled the ship towards the sky, and the wizard gave it the gas.
Again, I had to pause to figure wtf would happen. I flipped a coin. Heads, the ship zooms off, tails. The reactor melts and the ship falls from the sky and crashes again.
it was heads. The ship unloaded all the hellfire/sunfire from it's main engine, turning the desert below into a massive field of magically infused glass hellscape. Killing thousands of random bandits, citizens, and wildlife with the deluge of fire like a nuclear blast. The ship rocketd off into space, so fast the tunnel of air through the atmosphere it left collapsed and caused another explosion. The ship zoomed into space and into the Astral sea so fast (88% the speed of light), that the crew experienced time dilation.
The ship came to a halt, and powering down 3 weeks into the future.
The crew fixed the ship, and flew back to find the massive glass scar they left on the planet. In horror they flew down, completed the original objective they set out to do, and left the planet as quickly as they could.
we are a semi evil party on the way to full evilness. somehow we end up talking to an archdevil that wants to conquer all of the nine hells. coincidentally, my necromancer wants to conquer all the material plane. so we made a deal: every time i gain control over an undead through any feature, my control becomes permanent and without the need to maintain it. so there is nothing stopping me from raising entire armies with animate dead now. but this is not the war crime part. that part is that every undead i raise automatically get a hellfire weapon, which, if you dont know, is a weapon that sends the soul of anyone killed by it directly to hell, no matter how good of a person you were. so, im gonna have my massive armies killing civilians and combatants alike, and every dead person, even if they are literally the most pure creature to ever be born, go straight to hell.
Risking and almost wiping out an entire Tiefling city just because our Artificer was trying to punch a hole into this magical tower that was actually just an illusion to an alternate plane by using our flying vehicles warp drive that we were told had 45% of success.
Releasing a small legion of rapidly growing tree monsters on a civilian population.

That is a fun fact! Also terrifying in a way

As of the last session our warlock used telepathy to convince an old man that the gods commanded him to sacrifice himself.
Gaslight

We Revived Hittler And Exterminated Goblins And Kobolds Except For My Kobold

Huh.... I guess my DM missed that part. Or he just wanted to see what we'd do. I'm not complaining, it was a fun bit to do in character.
Ad&d. Cast resurrection on a litch, no spell resistance, no saving throw.
Big brain move
None yet but there is still time
Breaking me, the DM, into allowing so much.

there's a group in one of my campaigns who control the nation by giving people saplings and creating orphans
