Demon's Souls/YMMV


 * Accidental Innuendo: Sometimes, the Maiden's line "Touch the demon inside me" sounds a lot different from what it should mean.
 * Not to mention the item you use to give your weapon magic damage, Sticky White Stuff.
 * The Penetrator is going to pierce through your armor with his long, long sword.
 * Alas Poor Villain: Many get this feeling after killing
 * Some also get this feeling after
 * Complete Monster: Yurt the Silent Chief, who chooses to repay you for rescuing him from a cage by slaughtering multiple helpful NPCs in the Nexus before targeting you.
 * Also, Mephistopholes, his boss, who will task you to assassinate many good-aligned NPCs.
 * Crowning Moment of Funny: Backstabs with the Keel Smasher/Dragon Bone Smasher. The thing is taller than you are, wider than pretty much every humanoid enemy, and is blunt at the top. And then some enemies get back up again afterwards. The sight of it is just absurd.
 * Some item descriptions fall into this. The above-mentioned Dragon Bone Smasher's description ends with "Because of its immense weight, blacksmiths joke that it can scarcely be called a sword."
 * Crowning Music of Awesome: The music during the fight against . Its sinister sound suits the challenging fight.
 * The eerie and haunting piano piece when you fight Fool's Idol. Coupled with her sinister laughters in a dark, abandoned church makes a rather creepy atmosphere.
 * The organ piece during the "fight" with  fits the solemn mood perfectly.
 * Demonic Spiders: A literal example in that there is actually a gigantic demonic spider that breathes fire as the first boss of the second world.
 * The skeletons of the Shrine of Storms just keep rolling around and breaking your guard. And don't get me started on those gold skeletons.
 * The Black Skeletons are the stuff of nightmares, even more so than their silver counterparts, as they are wickedly fast when they decide to start running, are insanely powerful with a sudden leaping attack that will destroy all but the strongest defenses if it lands, have high defense that will shrug off most damage, and will follow you farther than any other enemy you encounter. They're like Terminators with katanas.
 * The Giant Depraved Ones in the Valley of Defilement. They hit hard, have a lot of health, are not easily stunned, and worst of all, are in a level full of Bottomless Pits and poisonous water that removes any and all of your mobility (and none of theirs).
 * Game Breaker: The Firestorm spell, which unleashes huge flames all around the user. Invading Black Phantoms love to spam this.
 * There's also the long spear, heavy armor, heavy shield combo. With the Brushwood Armor set and a sufficiently built up character, and a sufficiently strong spear, you have a powerful equipment based character that, while slow, can shrug off most hits, has a shield that can significantly reduce magic damage, and can attack without lowering his shield. This is effective against many of the enemies (and several of the bosses) of the game. Just level it up and add a bow for long range enemies, and the Keel Smasher for the more massive bosses, and you have Mighty Glacier that will shrug off all but the mightiest attacks, and can deal death in all 32 flavors. You can work on magic and healing spells in your second playthrough.
 * Obviously, having two experienced Blue Phantom players help you will allow you to storm through any level without you having to move a finger save for opening the fog doors.
 * In the very rare case that a friendly Black Phantom player invades, it can clear all enemies for you as they wont ever attack it. Of course, most of the time the friendly Black Phantom will be attacked by the host or a Blue Phantom as soon as it approaches them unless it took the time to send a message stating its intentions.
 * The Thief Ring. While its effect doesn't sound too exciting on paper, it's actually incredibly effective, allowing you to sneak right past everything, sneak up on Black Phantoms and soulsuck them and become invisible to invaders unless they move in on you (auras and such are still visible though)... oh, and it works on bosses too, including the Final Boss.
 * While not necessarily a game breaker, the Anti-Magic Field miracle can transform world 3 from "That One Level" into "Happy Squid Head Stab Time", since the squid headed guards (who have a powerful distance attack spell and a paralyzing field spell that they use to render you defenseless against a nearly 100% fatal attack) rely entirely on magic, and once you're up close to them, all they can do is try to cast while you stab them to death. It is strongly recommended that you get the 4-3 boss' demon soul, rescue Saint Urbain, and trade that soul for this miracle. It makes that entire world much, much easier. Just don't use it in co-op or pvp, since it can cause serious lag.
 * Dual Katanas. While not gamebreaking for the singleplayer portion, these have earned a lot of hate in PvP. Their attacks are fast, hard-hitting, and stamina-economic. To top it all off, it can combo a main-hand push into an off-hand attack, back into a main-hand push. The added damage following a push combined with the aforementioned stamina economy makes it possible to kill full-health opponents with one combo. To add insult to injury, it is one of the easiest combos in the game to land, as you can chain into it with three different attacks, all of which are powerful tools on their own.
 * Almost everything in Demon's Souls's Pv P could be considered a game breaker. By casting Light Weapon on an Iron Knuckle you can kill a high-vitality body form character with Second Chance active when they're at full health by headbutting them. It's an inescapable combo, unlike the Dual Katana combo mentioned above, which can be escaped. Despite all that, it's considered one of the worst set-ups in the game.
 * Goddamned Bats: The Valley of Defilement has Giant Mosquitoes who are very annoying if you don't have ranged weapons or melee attacks that work well on them. There's also an annoying group of hard-to-hit rats in the first level of this section. The main mook enemies, the Depraved are also somewhat this; they aren't very dangerous singularly but they can come in hordes, like to sneak up on you, can cause status effects and have an irritating push attack (that can be outright dangerous in the first map with all its pitfalls).
 * Also, there are Phosphorescent Slugs who have spit and lunge attacks. They are slow to move and are among the easiest enemies in the game, but are quite dangerous when in large groups, which is how you will often find them in the Valley of Defilement. They are even deadlier when found in tight places coupled with moving lights that explode on contact.
 * Good Bad Bugs: There is a small glitch in the Tower of Latria stage you could take advantage of so you only have to fight
 * Also, there is a bug that you can use to kill  before he even starts moving.
 * The item duplication glitch and the soul duplication glitch. The latter have been fixed in the latest patch, but can still be exploited by deleting the installation data.
 * Hell Is That Noise: The extremely jarring sound of the Mind Flayer's bell ringing in the otherwise silent world of 3-1.
 * Not to mention the ominous-sounding female voice (that turns out to be the voice of the Former Royal's Wife) that randomly starts wailing from time to time with no warning.
 * Also can be considered for Rydell for first-time players in 3-1. Hearing someone yelling and begging you to help them when you can't see them made this troper very nervous.
 * The Old Hero's roar when the player attacks him. This also acts as a warning - shoot him while he roars, and the results won't be pretty.
 * The Fool's Idol's Evil Laugh.
 * The background ambience and loud beating of the Old Monk's giant bio-mechanical heart in 3-2.
 * Memetic Badass: Due to his awesome looking Dark Silver Armor, ability to hold a giant mace in one hand and never let his shield down in the other, and all to protect his love, Garl Vinland was declared the manliest character in the game.
 * Memetic Mutation: "This is , please evaluate me."
 * "I'm in trouble, please recommend this message!"
 * No, his name is Ostrava, not Otsdarva.
 * And no, the white sprinkly particles that came out of Tower Knight's feet when you attack it are not Kojima Particles.
 * Moe:
 * Yuria, if the fan art is to be believed. Sadly averted.
 * The Maiden in Black, however, is a perfectly straight example.
 * Narm:
 * Despite the great seriousness that the Monumental's speech to you should be taken with, it's kind of hard to do because it has a noticeable lisp.
 * ridiculous hat. It makes him a whole lot less creepier.
 * Needs More Love
 * Nightmare Fuel: A few areas around Boletaria; the Prison of Hope especially, what with the mad prisoners, the royal mistress' singing, the iron maidens and the illithid-looking things...
 * The plague babies in the Valley of Defilement. *shudder*
 * Are you afraid of anything? If so, Boletaria has something for you. Hate bugs? Enjoy the six-foot centipedes with four faces. Does body horror terrify you? Then the Old Monk or the prisoners should really terrify you. Scared of the dark or of heights? Then the first two areas of the Tower of Latria will make it hard for you to sleep.
 * Paranoia Fuel: After a certain level. The Nexus, or starting hub, which seemed so safe, the only dangers coming from being an idiot (attacking some NPC's, falling long distances etc.), suddenly feels less safe when you notice corpses that weren't there before...
 * After the very first level you will only advance through dark hallways very slowly, with your shield raised high, and nervously rotating the camera around trying to spot enemies waiting to ambush you the second you move another inch.
 * Player Punch: Killing Garl tends to make people feel real bad about it.
 * Spiritual Licensee: Definitely one of the best game adaptations of Berserk yet.
 * That One Boss:
 * Another boss that can be That One Boss is the . It can be because
 * Most players agree that the undisputed That One Boss is because not only is it in constant motion, has magic attacks that stun you and can easily knock you down the bridge you fight it in, but
 * Flamelurker, who is very strong, very fast and agile, has powerful attacks that are boosted by fire damage and often knock you down, becomes stronger and changes his attack pattern as he loses life, and until you beat him, you can't forge many of the weapons and shields that would actually make him a little easier to beat, since his soul is needed to forge demon soul fortified weapons, as well as more than half of the other special weapon types in the game. The Dragon God, the boss that comes after him, is almost an anti climax boss fight in comparison...
 * That One Level: The Valley of Defilement. It's dark, you have to traverse wide-open areas so it's easy to get disoriented, most of the place consists of swamp that will infect you with Poison and/or Plague, and worst of all, while immersed in the water, you're completely incapable of backstepping and rolling, and your movement is severely slowed, making you a sitting duck for enemies that can easily kill you in one hit (and are otherwise, unaffected by the water).
 * The damn bridge in Boletaria 1-2. It's not bad when you learn how to play the game more effectively, but good lord. You have the dragon shooting you with the fire, but the worst part was of course at the end. Archers in front of you but you can't go forward to much you'll provoke TWO heavy soldiers and you can't move back anymore because the damn dragon will blast you.
 * Note that, if you blow it off, you can get a Composite Long Bow and about two hundred arrows (maybe 300 to be safe), then kill the Dragon. The catch is that the fastest way to get a Composite Long Bow is to go to area 4-1 (The Shrine of Storms), in which the Skeletons will rape the unprepared. What makes it worse is that to get cheap arrows, you need to rescue Graverobber Blige (his arrows are 10 souls each, while Boldwin's are 20 each) before you leave. To top it off, Blige never goes to the Nexus, so you'll have to go back to the Shrine of Storms to buy more from him. If you kill the Adjudicator though (assuming you manage the black skeleton before him), Blige will move to a much easier to reach spot, where you can buy the same stuff and more with less effort.
 * World 3, which has monsters that can paralyze and then One Hit Kill most players in a single attack. Plus, it's incredibly dark, and several paths drop off very suddenly, so you may be plummeting to your death before you fully realize you walked off the edge.
