* AnticlimaxBoss:
** Forgotten beasts and titans made of fluid tend to be this, since they fall apart at the slightest touch. If they have some additional ability such as deadly dust, they could be GlassCannon[=s=], but ones that rely on their body strength alone are just fragile.
** In earlier versions, werebeasts tend to change into their weak, naked humanoid form at the worst possible time (they're only beasts in the full moon), often the very instant after their arrival gets announced. This is no longer the case as of 0.40, where werebeasts are ''vicious''.
* BrokenBase: The [[VitriolicBestBuds friendly teasing]] that occurs between tile users and ASCII users, or between those who prefer Adventure Mode to Fortress Mode, is occasionally mistaken for this.
** Players that find {{Fan Nickname}}s fun and those who don't have been a straight example at times.
** Kobolds. Part of the community sees them as [[CutenessProximity adorable]] [[TheWoobie Woobies]], and the other part sees them as [[GoddamnedBats lowly thieves]] [[KillEmAll to be slain as soon as possible]]. (Although again, this usually escalates to [[VitriolicBestBuds entirely silly proportions]].)
** And you should see what happened with the tweaks to stone drop rate (where Legendary miners would once create a boulder from every square 100% of the time). The [[FlameWar !!debates!!]] are practically legendary.
** The modding community is quite split over the giant modpack known as [=MasterworkDF=], with some unaffiliated modders outright quitting due to lack of attention since [[SpotlightStealingSquad Masterwork usually had all the attention]], not to mention the criticism the pack itself gets such as occasional bugginess, ScheduleSlip and a complete lack of a unifying theme (essentially being Kitchen Sink modding where everything is thrown in). The fact the head of the project completely disappeared for an entire year due to a depressive crisis didn't help in the least. Outside the assigned board, and especially outside [=Bay12=], Masterwork is a sure topic to start a [[FlameWar !!Conversation!!]].
* ComplainingAboutPeopleNotLikingTheShow: This is...a bit more common than newcomers may be comfortable with, due to the game demanding a very different mindset from most other video games; a somewhat common response to new players expressing displeasure for the game is "no, you just need to play it more because [[NintendoHard Losing]] [[EarnYourFun Is]] [[MemeticMutation Fun]]!" While there are those who eventually warm up to the game, it can be irritating to be met with these sorts of responses if you just plain don't want to play anymore.
* DarknessInducedAudienceApathy: Not the game itself, which despite all of the horrors that can happen to fortress and adventurer alike has a fairly standard tone for a medieval fantasy game (even the literal legions of hell can be overcome if you're prepared enough). However, the game's notoriously steep difficulty curve ends up having the same kind of effect on many players, leading to the "losing is fun" mentality; if you're going to fail anyway, you might as well go all out.
* DemonicSpiders:
** Literally with giant cave spiders, as they are of the bear-sized, venomous, web spitting kind. They can trap dwarves with their webbing, paralyze them with venom, and go for the head for a straight kill. They never run out of web, either. If you ever see a zombie giant cave spider, RUN. RUN AND NEVER LOOK BACK.
** Wolves, especially in adventure mode, where they can ambush a hapless low-level traveler and kill them in a matter of moments, provided they're surrounded.
** Elephants have been toned down greatly from the days of {{LetsPlay/Boatmurdered}}, but [[LightIsNotGood unicorns]] have since gained a reputation as psychotic serial killers who brutally murder dwarves at random.
** Pond grabbers are the new carp. Not excessively hostile but if you fight them they are '''terrifying'''.
** In previous versions there were the elephants, then the carp (even Toady One thought he made them too strong). Now it's giant badgers. You also occasionally run into randomly generated enemies that are made of solid stone or even metal, and are as hard to kill as that would imply. To make things even worse, if the RandomNumberGod hates you, they can also have a dust attack that is, in its most deadly form, an InstantDeathRadius with about the same range as your archers.\\\
Also in previous versions, a Forgotten Beast made of poison mist. Then, a forgotten beast made of any intangible material could ''only'' be killed by being encased on obsidian or ice. However, forgotten beasts made of such material are now laughably easy to kill; one punch will tear off limbs.
** Although they're not strictly enmed.
* FanonDiscontinuity: {{Inverted|Trope}}; there are several iconic elements that have been patched out of the game, which the fanbase chooses to ignore and still treat as expected. Booze used to be MadeOfExplodium, for example, which caused [[HilarityEnsues hilarity to ensue]] when a ‼dwarf‼ decided that this [[ManOnFire weird orange stuff they'd been ignoring]] is making them awfully thirsty. Nowadays the booze just boils away, but nobody talks about that because it's less ‼fun‼.
* GameBreaker: Arrows and thrown objects were this in earlier versions. Before projectile velocity calculations were fixed, elven arrows (made of wood) could pierce through ''steel'' plate armour with little effort.
** Ballistas. There have been reports of people holding off huge raids with just one ballista, and people going on rampages in Adventure Mode with just a ballista bolt.
** Whips (blunt) and scourges (edged) have an extremely tiny area of impact and 5 times the attack force of other weapons. Compared to other weapon attacks, a successful hit by one of these will focus all the weapon's power (and weight) into a single point on the target rather than a wide area. This will nearly always instantly crush (whip) or sever (scourge) a body part, making them the best melee weapons in the game by far.
** Flails are [[FanNickname popularly known as lightsabers or hypersonic hammers]]. Like whips, they have a combination of a small impact area and high velocity.
** Weapon Traps are considered to be game breakers by some due to the massive amount of damage they deal. Likewise for cage traps, which unfailingly captures anything that isn't immune to traps, even megabeasts (and if you put a Giant Cave Spider web on it, it catches ''anything'')
** Economically, stoneware pottery. Fire clay can be gathered indefinitely and stockpiled near a magma kiln, which perpetually churns out crafts and large pots. Considering that stoneware can hold liquid without being glazed, you will never have problems with booze again. The value of stoneware crafts is comparable to obsidian, but are much easier to mass-produce; a few years of constant production will give incredible purchasing power.
** In adventure mode, sneak and find a tile where rocks can be picked up that is as close as you can get to the enemy's range of vision. Then start throwing the rocks until he dies (or passes out, at which point you can walk up and slit his throat), without ever being seen. A higher Ambusher skill makes this better, of course.
** In older versions, the so-called "[[FanNickname Danger Room]]" method of military training. Make a small room full of low-quality menacing spike traps. Fill those traps with practice spears. Attach them to a lever or repeater. Station a squad of dorfs in the room and watch their dodging, blocking, armor using, shield using, and weapon skills go up at a ridiculous rate. As a bonus, if any of them actually manage to get hurt, it gives your doctors practice, too! Later versions have significantly increased the injury potential of poorly-aimed practice spears while also increasing the skill-gain done from sparring with other dwarfs, so [[{{Nerf}} this is no longer the game-breaking training method it once was]].
* GoddamnedBats: '''Bogeymen.''' The only thing stopping them from being DemonicSpiders is that a decently skilled/strong character can usually manage to kill them; they're still absolute bastards, though, since '''[[FragileSpeedster you can almost never fucking hit them.]]''' Which is why, of course, every single person in the world tells you not to travel alone at night.
** Most thieving creatures, such as rhesus macaques, raccoons, but especially the flying ones such as kea and buzzards, because they have far more mobility and are therefore harder to kill.
** Magma crabs, only if you embark on a volcano though. They live in magma and are very resistant to bolts, and fire liquid basalt that will maim or even kill your dwarves. They will attack anything at every single possible occasion. They have MoreDakka. They spend years in the magma sea or volcano and will probably never leave. It's not very difficult to protect yourself against them, though.
** Quite a bit of cavern creatures, such as crundles, creeping eyes, but most especially hungry heads. Small, flying, come to your map as a lot, tend to get stuck in corners and scare dwarves, and harass dwarves like nobody's business.
** Kobolds, that is if you don't consider them as [[TheWoobie Woobies]]. Steal stuff, generally annoying, sometimes deadly, draw attention from more important tasks? Check all of these.
* GoodBadBugs: These are the kinds of bugs that make DF the game it is. Magma sea vanishing? Oops, it's all being [[spoiler:sucked down by a hole into '''HELL''']].
** Thirsty? Oh hey, I'm on the beach! Oh, I can't drink salt water? No problem! When you fall into water, your clothing and external organs get wet with an item called a "water covering". It's never salty.
** Due to a few of the particulars of combat and skill training, along with an overpowered bite attack, [[LegendaryCarp carp]] in previous versions had the ability to very quickly tear your people to shreds.
** A good bit of the popularity of the game -- aside from the whole ridiculously-detailed fortress-building thing -- is due to various bugs, perhaps "misfeatures", that produce unintentionally hilarious results: for example, dwarves not recognizing that they are on fire before attempting to drink from the extremely flammable booze stocks. The developer's constantly updated progress log is a good source for these stories.
** Spit coming out frozen is a recent one. The adventurer Toady was using ''hit'' it aside as a result.
** Pinching (yes, ''pinching'') was ludicrously overpowered in previous versions. Pinching someone in the neck while they're sleeping could ''sever their head and send it flying across the room''.
** And of course, the nicely illustrative, 'Got rid of world gen crash during succession after death of prolific long-standing position holders with inbred descendants.'
** A bug in the way cooking ingredients used to work, which enabled a cook to produce solid meals out of nothing but booze; this has since been fixed.
** Due to a rather peculiar glitch that has since been fixed, ordering the construction of metal goblets would turn even the most valuable bars into iron mugs. Some reported that iron bars turned into gold, as something of an alchemical counterbalance.
** You can throw things without having usable arms. Or legs for that matter. Apparently your character spits them out.
** For the first few 2010 versions, it was possible for creatures, including your dwarves, to ''[[ImMelting melt]]'' if caught in the rain in a warm area. This leads to one of the most ridiculous exploits ever in Adventurer mode: by going in and out of fire to melt all the fat in your body (but avoiding bleeding to death in the process) [[http://www.bay12forums.com/smf/index.php?topic=54174.0 you become effectively fireproof.]]
** Speaking of which, the Adventure mode also has several conditions where your controlled character suddenly shifts to some other creature. Overlaps with {{Game Breaking Bug}}s depending on luck and personal preference as you may get something stupid like a kobold or something horrendously awesome and nigh-unkillable like a bronze colossus.
** More in adventure mode: the effects of walking with a crutch (speed becomes dependent on crutch-walking skill, which grows as you move) only cease when you drop a crutch, ''not'' when you put it in a container or throw it. This lets adventurers missing legs regain mobility without losing use of a limb in the process and sell back crutches they're already "done" with.
** Water will freeze in cold environments, the resulting ice can be mined out like stone, it will melt if it gets too warm. This is all logical and expected. But constructions built out of ice will ''never melt''. You can build a magma aqueduct out of ice if you so desire.
** Normally, necromancers and other unnatural types make people around them increasingly suspicious with their agelessness until they're run out of town. So, from the devlog: "In bug news, the zombies in a necromancer's tower became suspicious after the necromancer failed to age, and he fled into the hills."
** [[http://www.bay12games.com/dwarves/index.html#2011-08-17 More necromancy hilarity]], as we see the very silly results when certain abilities are not tied to specific body parts:
--->'''Today:''' Then I talked to one of [the resurrected severed limbs], and it told me that it was peasant. It was flattered but had no need of my services. I imagine its little fingers were shaped into the form of a mouth and they flapped back and forth while it spoke with a high-pitched voice. I guess there's still work to do.
** Dwarfs ordered to remain inside (40d) or in a burrow (2010 and newer) will exhibit a few bugs. A [[MadArtist moody]] dwarf will ignore this order when deciding on what workshop to take, and will bring items to said workshop even if it's outdoors/out of the burrow. One still-standing glitch causes a moody dwarf to forget whether or not he brought items to a workshop that's outside of the area he's supposed to be in. Cue the creation of [[http://df.magmawiki.com/index.php/Planepacked Planepacked]], which took over a year for all the materials that ended up being used to be gathered and contained '''''73 images of itself'''''.
** A bug that briefly appeared in at least one version caused a sort of Goblin Civil War. Somehow, goblins were divided on whether or not they were loyal to Non-goblin leaders of goblin civilizations. This caused Goblin ambushes and sieges to immediately start killing each other as soon as they arrived on the map.
** In one version of Adventure mode, sleeping on the beach may result in you being ambushed... by fish that immediately drown as soon as the battle starts.
** BodySurf: Before 34.11, it was possible to suddenly shift from controlling an adventurer to an underground creature (even [[spoiler:a demon]]), then to bodyswap to some other animal every time you go to sleep... and they still can talk. Humans [[http://www.bay12forums.com/smf/index.php?topic=75246.msg1889160#msg1889160 are okay with a talking elephant]].

-->"[[http://www.bay12forums.com/smf/index.php?topic=75246.msg1888981#msg1888981 I'll bet you didn't know cave crocodiles have high musicality.]]"
** When a caravan appears and you have a hospital zone designated, your dwarves will sometimes pour out of the fortress en masse, steal all the cloth the merchants are carrying, and take it to the hospital to use as bandages.
** Historical figures can survive having their [[OffWithHisHead necks ripped off]] in world-gen, only to [[PuffOfLogic instantly die]] once they show up during actual play.
** The delivery of magma to your fort in bags carried by traders tends to lead to your depot exploding, but it's hard to argue with any trade good so dwarfy.
** In versions .40 and .42, wandering bandits and armies can be composed of nothing but domesticated animals. Such groups can even invade and take over civilized sites in world gen, ''Literature/AnimalFarm''-style.
** Early versions of .42 had a bug which caused ''horses'' of all creatures (and only horses) to spawn in ludicrously huge numbers, often up to 3600 per site. It got to the point where what was identified in-game as a goblin settlement would in reality consist of one goblin and thousands upon thousands of horses. Several people even found the game would let them control a horse in Adventurer mode.
* ItsHardSoItSucks: The game has a very high barrier to entry that new players compare to flying a passenger jet with no training or experience. Newcomers are advised to ditch the mentality that losing is a bad thing ([[CatchPhrase "Losing is fun!"]]), but many still are reluctant to try for more than five minutes.
* MemeticBadass: Toady himself. When you look at what he created, it's not all that surprising.
** Any fortress will create a few of these if it survives long enough, but some are truly exceptional, such as the backpack-wielding dwarf of Syrupleaf, or the dwarves of [[http://df.magmawiki.com/index.php/Bronzemurder Bronzemurder]].
** Captain Ironblood who never bathes (and is thus literally covered in blood, mud and vomit at all times) and can kill titans and dragons on his own. He eventually took up seige weaponry use as a hobby.
** [[AwesomeMcCoolName Cacame Awemedinidae]], [[NamesToRunAwayFromReallyFast The Immortal Onslaught]], Elf King of the Dwarves. According to the (partially player-invented story), he joined the Dwarven military after his wife was killed and eaten by other Elves, just so that he could kill more elves. He proved to hate elves so much, that he was made the Dwarven King.
* TheScrappy: [[ScrewYouElves Everybody hates the elves]]. They're irritating, stuck-up little bastards who spend all their time getting snooty at you for chopping down trees or selling them wood and trying to sell you poor-quality trade goods ([[HypocriticalHumor made of wood]]). Elves are basically the ''reason'' people invented [[TakeThatScrappy trade-depot-drowning traps]], [[IronicHell surround elves in cages with lots of wooden trade goods]], or quite a bit of other weaponry.
** Players also devote a lot of time and energy devising "[[VideoGameCrueltyPotential unfortunate accidents]]" to befall their nobles. This may count as KickTheSonOfABitch (or ShootTheDog, or PragmaticVillainy) considering most nobles are currently useless, arrogant and haughty, and require stuff constantly only to keep them happy.
** Migrants with near-useless skills, such as cheesemakers, small animal dissectors, trappers, etc.
* ScrappyMechanic:
** The economy in 40d. There's a widely recommended option to turn it off, and several other options to turn it down if you do permit it (none of which allow you to convert a stack of coins from a blindingly spammy list of one-coin objects.) [=DF2010=] just scrapped the whole thing until Toady can make something that isn't horrendously broken.
** Force mechanics in post-0.42 versions, because ''everyone'' is MadeOfPlasticine due to them and armor doesn't help anyone. It's quite a blasted annoyance when you lose your adventurer or champion dwarf because a lucky shot to the fingers that glanced off their *Steel Left Gauntlet* somehow still imparted enough force to twist their wrist/elbow/shoulder into a gordian knot, tearing muscles, tendons, ligaments and nerves and collapsing the victim into a helpless heap of pain with no chance to prevent it.
* SequelDisplacement: Slaves to Armok Chapter 1? [[http://www.bay12games.com/armok/download.html What]]? Possibly inverted -- at this point, Dwarf Fortress is popular enough that "people who would never have heard of Slaves to Armok 1 if not for Dwarf Fortress having that conspicuous 2 in its full title" probably outnumber "people who might have actually played Slaves to Armok 1 if not for Dwarf Fortress being more polished and popular" by quite a lot.
* TearJerker: [[https://www.reddit.com/r/dwarffortress/comments/4v5kno/a_heartwarming_gem_from_my_adventure_mode_game The stars are bold tonight]]. A tale of two adventuring companions having one last conversation as one of them lays mortally wounded, and the game's procedural generation allowing for some unexpected depth.
