''Dungeons & Dragons Online'' (or ''DDO'') is the {{MMORPG}} counterpart to [[TabletopGame/DungeonsAndDragons the pen-and-paper game we all know and love]] (mostly based on edition 3.5). As such, it has all the dice-rolling, kobold-smacking goodness of Dungeons and Dragons, with all the button-mashing, leet-speaking addiction of an MMORPG.

It was launched by Turbine in 2006 as ''Dungeons & Dragons Online: Stormreach''. The game has since been renamed ''Dungeons & Dragons Online: Eberron Unlimited''. (The latest update appears to have removed ''Eberron Unlimited'' from the logo, but is still referred to as such in reference materials and on the main website.) It is based in the campaign world of {{Eberron}} (yeah, [[{{Magitek}} the Magitek one]]) and is set on the fictional continent of Xen'drik. After years of being a pay-to-play game, it was rebranded as a free-to-play game with premium content that could be accessed by becoming a VIP (which is simply maintaining a paid subscription) or spending Turbine Points on it. The player character is initially thrust into a plot that involves an evil Devourer cult, sahuagin, a dragon, and a lot of snow.

As of June 2012, an ExpansionPack was released that introduced epic levels and allows players to adventure in the ForgottenRealms. AndThereWasMuchRejoicing indeed.

For additional examples, see {{Eberron}} for the general setting, and [[DungeonsandDragons the Dungeons and Dragons page]] for general gameplay tropes.

----
!!Contains examples of:

* AbsurdAltitude: If you're running the Vault of Night raid and have a newbie in group, [[SchmuckBait tell them it's tradition to cast or put on an item with feather fall and jump off the side after you've finished.]] You're so high up you can see the curvature of Eberron itself. You invariably float down to the Marketplace, but about 10 feet off the ground - whether you're under the effects of feather fall or not - you die. Yes, this does make you a giant troll, but the view is incredible.
* AbsurdlySharpBlade: Vorpal weapons.
* AbsurdlySpaciousSewer: ALL of them! Why else would there be monsters down there for you to kill?
* ActualPacifist: You get bonus experience for completing a quest without killing anything. [[EverythingTryingToKillYou Good luck with that]].
** All jokes aside, a select handful of quests are uniquely suited for evading all the mooks with Invisibility and/or Dimension Door, allowing one to run them very quickly and collect that bonus. Also, the quest called "Frame Work" has some amusing variable dialogue depending on how covert or [[ShootEverythingThatMoves omnicidal]] you were.
* AdaptationalBadass: The Lord of Blades is ''much'' stronger than he is in [[{{Eberron}} the main setting]].
* AdjectiveAnimalAlehouse: The Wayward Lobster and The One-Eared Bugbear Inn.
* AlienSky: Xoriat, Dal Quor, and the Demonweb. Xoriat has red clouds everywhere, and space seems to be rippling. Dal Quor looks like space with a purple tint to it and with buildings floating around. The Demonweb is a purple void with occasional red "stars" and bits of rock connected by webbing.
* AllMonksKnowKungFu: The Monk class can follow two prestige paths, both a type of WarriorMonk where you are a Whirling Dervish of punching destruction or a serious bane to undead or extra-planar creatures with some Cleric abilities. The Monks have it cool by using KiAttacks and not spellpoints (mana) to power their elemental and special attacks.
* AllTrollsAreDifferent: These ones are tall, green, have tusks, and regenerate from anything and everything unless you hit them with a dose of fire or acid after knocking them out.
* AllegedlyFreeGame: Theoretically playable for free after about level 12... but only if you're willing to do a lot of grinding. Or suffer from major {{Altitis}}. Which is quite likely.
** Mind you, you will probably accumulate enough Turbine Points by then to buy an adventure pack. Also,with the new Lordsmarch Plaza free to play chain and some high level free to play quests afer that,you can get that number higher.
* AnAdventurerIsYou: And everyone ELSE, too! Including several of the [=NPCs=], [[InformedAttribute apparently]], but they're worse at it than you are.
* AnnoyingArrows: Enemies with ranged attacks are pretty pathetic compared to enemy spellcasters. You can take several arrows to the face and keep going, relying on your magical equipment and lots of hitpoints to keep you alive, but there's not a lot that can save a low-medium level character from a Disintegrate, Harm, or Touch of Death spell.
* AnotherDimension: Shavarath, Xoriat, Dal Quor, and a couple of [[PocketDimension demiplanes]] are all accessible as part of quests.
** As of the new expansion, the [[EldritchLocation Demonweb]] is also accessible.
* ArbitraryHeadcountLimit: You can only fit 6 people into a typical party quest. For raids, you're allowed 12 heads.
** The game tries to justify that in one raid, Zawabi's Revenge, in which the Djinn that teleports you to the quest asserts he only has energy to transport 12 people into the Demon Queen's refuge.
*** You'll need all of them too. It's a 12th level raid, and the end boss is level 22.
* ArmCannon: The Artificers' Rune Arms.
* AutobotsRockOut: Some of the battle themes in the Maleficent Cabal Chain. Most prominent in "Under The Big Top".
* BackStab: The Sneak Attack ability is pretty much the only way for a rogue to do damage. [[ForMassiveDamage But when they do...]]
* BagOfHolding: Including sew-on pockets that can hold fifteen sets of plate mail. And then you can get another inventory page by paying an NPC to craft a broken Portable Hole into a literal pocket dimension.
** There are also bags for holding crafting ingredients, gems, and collectables looted from mobs, so that you can save on inventory space.
* BallOfLightTransformation: The game features [[http://ddowiki.com/page/Ghaele_Eladrin_race Ghaele Eladrin]] that can take the shape of a lantern archon.
* BattleInTheCenterOfTheMind: Comes in the quests "Finding the Path" and "I Dream of Jeets", and also comes in the final boss battle of the Harbinger of Madness chain.
* BigBad: None, really, but the closest the game has are Horoth, the Black Abbot, the Stormreaver, the Devourer of Dreams, and Lolth.
* TheBigGuy: The melee classes: Fighter, Barbarian, Paladin, and (to a lesser extent, it depends on the build) Monk. Clerics have a bunch of HitPoints and good armor, and shields, too.
* BlackoutBasement: The quest "Rainbow in the Dark", where the only source of light is a scepter that you have to carry to the end of the dungeon. You can use [[MuzzleFlashlight certain attack spells and Runearm blasts]] to light the way.
* BodyHorror: The Harbinger of Madness chain is centered around strange creatures called the Taken. While they look creepy enough on their own, it gets worse when you learn how they're made. [[spoiler: They were created by a Mindflayer "Artist" who crafted them out of kidnapped Stormreach citizens.]]
* BrainwashedAndCrazy: Happens a few times.
* BossSubtitles: Most named enemies have a subtitle under their names, some of them quite funny.
** The Cultists in the Korthos Island chain.
*** And their dragon. Upon being freed, she kills her controller and leaves.
** Near the end of the Maleficent Cabal chain, [[spoiler: Yewil d'Phiarlan and her troops]] are victim to this, and eventually [[spoiler: [[DyingAsYourself Die As Themselves]]]].
** The Silver Flame agents who were sent into the Cursed Crypt. Also, if you linger too long in there, the player characters.
** You find out that this is the case after picking up the first journal in [[spoiler: Let Sleeping Dust Lie]] with regards to [[spoiler: the Crimson Feet]].
** The cultists in Lords of Dust.
** Silver Flame agents again in [[spoiler: Wrath of the Flame]]. By the same person who [[spoiler: brainwashed Yewil back in the Big Top]].
** Pretty much any and all [[PathOfInspiration Inspired]].
** And finally, in a late-game raid, [[spoiler: the Lord of Blades]] himself, by [[spoiler: quori]]. Though he likely would have tried to kill you on his own anyway.
* BreastPlate: Averted for the most part; armor for characters in general tends to look more or less the same whether you're playing a guy or a girl. The Armor Appearance kits, on the other hand...
** After the update that turned the game into ''Eberron Unlimited'', a number of these kind of armors have shown up for female characters. They even vary in... erm, "capacity" depending on race.
* BreathWeapon: Artificer Iron Defender pets have a fire and acid variation. Characters with the Draconic Incarnation Epic Destiny can also learn a Dragon Breath attack.
* CallBack : When Gnomon [[spoiler: reveals his true intentions, he mentions causing damage by killing innocents and attacking other religions.]] Why is this a callback? One of the earlier quests involve [[spoiler:him ordering you to kill a group of Sovereign Host followers,]] calling them heretics.
* BribingYourWayToVictory: Costly [[PrecisionFStrike flippin']] skill books...
** Special classes, races, and other features like Veteran Status can be unlocked by raising your favor with various factions, but you can also buy them off the DDO Store.
* ChangingClothesIsAFreeAction: Switching armor takes time but swapping between or to robes and outfits is instantaneous.
* CharacterAlignment: This matters if you want to use armor of stability (which requires a TrueNeutral alignment) or a True Law/True Chaos/Pure Good weapon. Or if you're dealing with something capable of dealing alignment damage. Or if you want to be a Paladin/Bard (you can't; paladins must be LawfulGood, bards must be nonlawful.)
** Evil items will give you a permanent negative level until you take them off, unless you are of neutral alignment.
* CharacterCustomization: Stat-wise, this is one of the most flexible games on the market. Appearance-wise... maybe not so much.
* ClassAndLevelSystem: Much like D&D 3.5 core.
* ClimbingTheCliffsOfInsanity:
** Jumping (or getting thrown) off of the top of Tempest Spine while wearing a feather-falling item can make you float a '''really long way'''. Jumping (or getting thrown) off of the top of Tempest Spire while NOT wearing a feather-falling item can make you die from falling damage, and your teammates are going to be reluctant to come pick up your corpse so you can get your loot, because it is a ''long'' way back up, and likely involves running past fields of fire elementals.
** The Coalescence Chamber in the Vale of Twilight, filled with several very deep shafts, will make the best of friends want to tear each other's throat out and pick-up groups wind up with squelching angry, inexperienced and frustrated players about 90% of the time.
* CompellingVoice: Bards. Compelling enemies to sit still and listen to your lute ([[HyperspaceArsenal which doesn't even appear in your inventory, let alone contribute to encumbrance]]), to compelling your allies to feats of Heroism. Also, the Charm/Dominate Person/Monster spells, and Suggestion.
** Players can earn the items "Voice of the Master" and "Mantle of the Worldshaper" from the quests that the D&D creators narrated. Worn together, the player receives the True Seeing ability (Hello, hidden doors!).
* TheComputerIsACheatingBastard: At least in terms of computer-controlled casters. They have no [[VancianMagic spellpoints]] bar and seem to ignore the cooldown rules on spells that limit a player's spell use, especially obnoxious when the computer caster in question is a healer who can full-heal quickly with their infinite violating the VancianMagic rule with unlimited spell points. Damage almost never interrupts their spells, either, [[ComputersAreFast as if enemies have all of their spells quickened]].
** In a somewhat related note, computer-controlled '''ally''' Hirelings have no metamagic feats and thus can't improve any of their spells in a pinch.
*** Hirelings also DO have spell point bars, though typically slightly higher than player characters. The end result? Enemies have unlimited spells, but your party has a cut-off.
**** They do however, seem to have truckloads of potions.
** Enemy archers never run out of ammunition and maintain a rate of fire that only repeating crossbows can compete with, and they can target invisible characters by sound.
* ConvectionSchmonvection: Swimming IN lava causes a moderate amount of fire damage, but nothing serious. But walking right next to it (or on those METALLIC catwalks in the Firebrand Mines and Burning City) seems to have no ill effects.
* CreatorCameo: Creator/GaryGygax and DaveArneson are the DM/narrators in two different series of quests.
* DeathIsCheap: Well, except for when it comes to your equipment.
** Death becomes less cheap when there's no healer and no resurrection shrine nearby. In that case, the only way to revive yourself on the spot is to [[BribingYourWayToVictory buy an item from the DDO store]].
* DoesThisRemindYouOfAnything [=/=] DoubleEntendre:
** The world "Melf" in ''M'''e'''lf's'' Acid Arrow tends to be spelled with the wrong vowel.
** "We beat them off... this time."
** Jeets Shimis (speaking to the female cleric Cellimas): "Ha, I still got plenty of stamina! I can go all night long!" Jeets in general has a lot of things to say similar to this, usually related to Cellimas. "Tell her to keep her knickers on." "Don't worry, Cellimas. I'm here to watch your behind, now."
*** And he is a halfling, so his eyes are at just the right level
* DualWielding: Basically the whole [[IncrediblyLamePun point]] of a melee-based ranger. Any class can do this to varying degrees of success.
* DumpStat: Every class will have to pick one if they want to be the best at what they do. However there is a number one rule of character builds that all veteran players agree upon: "Con(stitution) is NOT a dump stat" for any class, due to hitpoints being extremely important for fighting (and sometimes the only defense against) high level monsters.
* DungeonCrawling: Or, with the tumble skill, dungeon rolling or even dungeon backflipping!
* DungeonPunk: With a late 2011 update, the world of Eberron reemphasized how Dungeon Punky it is by now filling it with gadgeteers of gears and magic: The Artificer class.
* EldritchLocation: Xoriat, Dal Quor and the Demonweb all have [[AlienSky weird skies]] and lack a real surface.
* ElementalPowers: Sorcerers and Druids can specialize in an elemental power. Likewise, Monks can [[WesternAnimation/AvatarTheLastAirbender go at it "Avatar"-style]] through attacks and stances that channel Air, Earth, Wind and Fire.
* EliteMooks: There seems to be a couple of these in every major dungeon. Commonly referred to by the players as "nameds," or "named monsters" [[CaptainObvious because they have a name]] and a treasure box.
** Can be more specifically referred to as "orange-" or, in higher levels, "red-names". Reds are normally "bosses," in the sense that they command the other enemies. Most of them are just PalletSwaps or regular Mooks.
* EnemyMine: Pretty much the entire storyline in the Necropolis quests regarding [[ReligionOfEvil The Emerald Claw]] and the [[CorruptChurch Silver Flame]].
* EscortMission:
** The crazed, ineffective magic attacks of Coyle, a non-player character you must protect for 15 eternally-long minutes in a Ruins of Threnal quest chain. If he dies, you fail the quest. Keeping the little bastard from attracting any attention that will get himself killed was made a little easier when the game developers allowed players to give Coyle a TapOnTheHead as required.
** Gladewatch Outpost Defense involves protecting the captain of a defense regiment while she defends the outpost from attacking goblinoids and ogres. Oh yeah, and she left her soldiers at home too, so it's just your team and her. Make sure to have at least two healers, since she tends to run off to attack whenever a new enemy spawns. You can try to talk her out of it, but even then you have to make sure she doesn't see anything hostile on the way to wherever you're hiding her.
** In many of the more recently-added quests, the developers have trended toward escortees who can fight or make themselves invincible, but not both at once. Your character can even say in dialogue on one occasion, "I dislike escort missions. They always die too easily or fall off ledges and there's nothing I can do about it," to which the VIP outright tells you not to worry about his safety.
* FakeBalance: Rogues get the shallow end of the DPS pool. Sure, sneak attack can do some [[ForMassiveDamage massive damage]], but it doesn't catch up to a fighter's damage output until about level 12, and even then it doesn't work against undead, elementals, oozes, constucts, an enemy with a Fortification (depending on how much it gives) item, or other human players in 1-on-1 PvP.
* FanServicePack: Game updates in late 2010 added armor kits, which allows a player to make their character's armor or clothing more cosmetically exciting, intimidating, or attractive. Female outfits and robes often (among other things) BareYourMidriff, add a CleavageWindow, or grant a LeotardofPower.
* FiveRaces: Eight, actually: Humans, Elves, Halflings, Dwarves, Warforged, Drow ([[OurElvesAreBetter which are like other elves, but with more stat boosts]]), [[HalfHumanHybrid half-orcs]] and [[HalfHumanHybrid half-elves]].
* GadgeteerGenius: The Artificer class.
* GameMaster: A well-voiced narration to help set the tone.
** One of the quest areas is even GM'd by Creator/GaryGygax himself, and another by fellow ''D&D'' creator Dave Arneson.
* GenreSavvy: In many newer quests, some of your character's possible dialogue is written as though spoken by a hack-and-slash gamer, such as telling a villain to [[ShutUpHannibal stop monologuing about his evil plan]] and start fighting, or complaining about annoying gameplay.
-->'''Player Character:''' Are you going to [[LeeroyJenkins charge at the first monster you see]] and [[SuicidalOverconfidence cast magic missile]] at it?
--> '''Foreman Wee Yip Yip:''' Are you bonkers?! Kobold Foreman Wee Yip Yip not get promoted to Foreman for being a hero! This kobold a lover, kobold no fighter! Kobold like his job and his life and his family very, very much. Kobold stay right here. And if scary things come knockin' Kobold squeal and run around like a little girl, like any sensible Kobold should!
* GogglesDoNothing: As of Update 22, you can visually show off goggles over your character's forehead.
* {{Golem}}: the Warforged race, a living construct that (paying) players can choose to use. Not-so-nice golems populate the dungeons as well.
* GoLookAtTheDistraction:
** The Intimidate skill. Technically more of a "come here and look at me distracting you," but still.
** Would be more suited to the Diplomacy skill. "Hey, here's a great idea. Go lodge your axe in my friend's skull instead."
** Bluff fits even better; it works even when you're alone. Also the best skill for Rogues, because it opens up the target to Sneak Attacks.
* GoodIsDumb: In the case of the Catacombs, a crypt under the tower of the Silver Flame. You'd think a church dedicated to destroying the undead could deal with an undead infestation in ''their basement'', but no, it's time to call in the adventurers. Adventurers who, by the way, are likely to destroy each and every sarcophagus they find so they get more experience points, and will expect you to pay them with expensive magic items when they're done.
** The Silver Flame is a bit of a CorruptChurch in places, mired in their own bureaucracy that hobbles them from working as well or as effectively as they could.
** The GoodIsDumb trope is actually lampshaded by Archbishop Dryden, who refers to the guards as "quarter-wits." [[spoiler: At the time he was possessed by his wraith brother, so we don't know how valid this statement is.]]
** They also had a [[spoiler: ''[[AlwaysChaoticEvil rakshasa]]'']] in their ranks for several years, and no one had a clue.
* GottaCatchEmAll: Collectibles, trade-able items, quests, favor... take your pick.
* HighlyVisibleNinja: If your teammate is using the Hide command, you see them crouching with their avatar slightly darkened. Also, some enemies will use the Sneak command, with almost no effect due to their pitiful skill checks; you can still target them and hit them just fine.
* HitPoints: Notably changed from the paper-and-pencil version in that every character starts with the Heroic Durability feat, granting 20 hit points. Toughness's effect is also increased from just 3 HP to 3 HP at 1st level and 1 HP every level thereafter, without losing the stacking ability of the original.
* HumanoidAbomination: Belashyrra, one of the daelkyr, appears as an ArcVillain. He looks like a man with long blond hair, but he's covered in chitin armor and speaks in a distorted double voice.
** Most of the Quori are also this.
* HyperactiveMetabolism: Averted. You'll heal {{hitpoints}} and {{mana}} naturally when standing around in Stormreach city, but you can drastically increase your regeneration rate for a couple minutes by eating food and drinking juice. Or consuming oil, if you're a Warforged.
* IngestingKnowledge: Until a recent update, your character used stat-enhancing books pretty much exactly like this.
* InsurmountableWaistHeightFence: Averted by the characters' ability to jump, or clamber over shorter objects like large crates. Occasionally played straight as part of an...
* InvisibleWall: There are some places in Stormreach harbor or marketplace that you just can't get your character to go, despite logic. This was made especially evident when Turbine released the Head In The Clouds festive buff; your character can jump insanely high, but if you jump too high you hit your head on Stormreach's invisible ceiling.
* InvoluntaryDance: The Otto's dance line of spells: Resistible, Irresistible, and Sphere of Dancing. Nearly all creatures with minds (including the player characters) can be affected by it.
* KamehameHadoken: An Epic Destiny for epic players in the new expansion, Menace of the Underdark, allows powerful ranged KiAttacks. Later updates also allow a new Monk class tree, the Henshin Mystic, to weaponize ki this way (albeit not as dramatically as Son Goku).
* KillItWithFire: Neophyte spell-casting adventurers will throw Walls of Fire at the blink of an eye. That's fine and all until they realize that the enemy AI sets its sights on them and squishes them flat. Not a tactic against Iron Golems (fire heals them) or {{Devil}}s and Demons (they eat fire for breakfast).
* KnightTemplar: Inquisitor Gnomon of the Silver Flame. He has characters wipe out a shrine to the ''Sovereign Host''. [[spoiler: Turns out that he's actually a powerful rakshasa working for the Lords of Dust who has been trying to ruin the Silver Flame from within]].
* LargeHam: Lars Heyton coincidentally has the same initials as this trope. "Sahuagin SCUM! Keep coming, I won't die that easily!"
** The DM for the new version of Heyton's Rest is also quite given to hammery.
* LeeroyJenkins: Player characters that do a Leeroy in a quest are likely to get themselves (and any guild they represent) a blackballing reputation. While in a quest, a party leader can't dismiss a player, but others may choose not to heal the offending player or even carry his Soulstone (death token) to where he has a chance to revive.
* TheLegionsOfHell: The Devil Legions. In fact, the same type of devil in that page's image appear here.
* LeParkour:
** Running around on top of the buildings in the Stormreach marketplace can be kinda fun, and it's an integral part of the [[ChristmasMode Easter event's]] egg hunt. It more or less requires a Feather Fall effect of some kind, though.
** Players with light or no armor and high Jump skills often use this way to get about town very quickly. For Monks, it fits their {{Wuxia}} style, obviously.
* LevelGrinding: Thankfully, every character gets bonus experience for doing a quest on any difficulty the first time, and most quests come with 3 or 4 difficulty levels to shake things up a little bit. You also get bonus XP for [[DieChairDie Breaking everything you can]], [[OmnicidalManiac killing everything you can]], [[ActualPacifist not killing anything]], not dying, not leaving the quest until it's done, and disabling traps/finding secret doors.
* LinearWarriorsQuadraticWizards: Just like the original ''[=DnD=]''; Fighters (and the like) start off doing respectable damage that increases slowly over time, while wizards go from their 1d6 Magic Missile damage to spamming Quickened Meteor Swarm for 4 times 8d6 damage twice a second, not to mention the crapton of damage boosts they get by that point.
** This ''does'' switch around every few updates or so as new content is released: at one point, having more than one arcane caster in a raid (out of 12 participants) was considered a waste of a DPS slot, being relegated to crowd-control duties.
* LiterallyShatteredLives: The common fate of enemies who die to a cold weapon or cold-related spell.
* LostForever:
** You get one and only one ember weapon per character, and they're non-tradeable. Here's hoping you have some other way to attack with fire or acid when you finally meet some trolls.
** Finish Misery's Peak you only get one shot at the end rewards, which are the second half of a two set piece that gives a class related bonus depending on which one you pick. Choose wisely, because you can't trade your pick in for a different set.
** In a more abstract way, your starting stats. Put too much strength on your wizard? Well, you can either start over or [[BribingYourWayToVictory buy a Heart of Wood (rerolling token)]] and fix those stats.
* TheLostWoods: The King's Forest. the Storm Horns and, minus a lot of woods, the Underdark.
* MacGuffin: The entire game is filled with enough of these for an adventurer to open their own shop. From the early-level Seal of Shan-to-Kor, to the three artifacts for the Demon Queen, to the ridiculous Sigil Frame of eight pieces in the last Necropolis quest, this game lives and breathes this stuff.
** Some of the objects actually do stuff, and others are just valuable.
* MadArtist: The main antagonist of the Harbinger of Madness series is a [[spoiler: Mindflayer artist, Yaulthoon, who specializes in making sculptures...by turning kidnapped Stormreach citizens into monsters called the Taken.]]
* MadeOfExplodium: Lots of stuff.
** Trap boxes explode if you [[CriticalFailure fail badly enough]] when trying to disarm them, [[ExplodingBarrels certain barrels]] will explode if you hit them with anything (including but not limited to: your fists, swords or clubs, arrows, crossbow bolts, shurikens, and elemental magic (even [[FridgeLogic ice]] [[IncrediblyLamePun magic]]), symbols of fire ignite if you go anywhere near them, and if you kill an enemy with a fire attack, its corpse will light on fire and burn away. Frozen enemies explode into ice fragments.
** In the "Irestone Inlet" quest, you rig a boat with barrels of gunpowder and light the fuse. It's even possible to do this without the guards on board realizing you're there. Oh, and if you're standing too close to the boat when it blows up, the shockwave pushes you away.
** Players in the quest "Siegebreaker" encounter an entire room filled with explosive barrels that cascade their explosions. There are two HUGE super-barrels that will outright kill anyone on exploding if the player is on the same plane of the things. The Dungeon Master voice [[LampshadeHanging puts a light on this humorously.]]
** Also the "Blown to Bits" quest, where the crates of weapons get ExactlyWhatItSaysOnTheTin. Even has an optional golem boss who offensively uses mines.
* {{Magitek}}: The cranes in Stormreach Harbor in Ebberon, for instance. Also pretty much every light source in the game, except the sun and a few fire pits.
* ManaPotion: The rather expensive Potions of Mnemonic Enhancement, which restore your Spell Points.
* MassMonsterSlaughterSidequest:
** The Slayer bonus, which gives you experience for killing X amount of enemies in a wilderness instance.
** Certain dungeon quests, such as "The Butcher's Path," will also have you killing X amount of monsters as one of your objectives on the quest, either as a main objective, or as an optional objective for extra experience.
** The later-released Monster Manual provides you with bonus EXP and Turbine Points for killing certain amounts of certain types of monsters.
* MasterPoisoner: The Ninja Spy has its own brand of deadly damage-over-time poison that even works on bosses.
* MeatMoss: Shows up often in quests where the Plane of Xoriat is involved.
* MechanicalLifeforms:
** The Warforged, created and given souls by [[AWizardDidIt ancient and vaguely defined magic]].
** There's also the Iron Defenders, which Artificers get as pets, and which you fight every now and then.
* TheMedic: Don't leave Stormreach without one. If an enemy comes with his own healer, [[ShootTheMedicFirst he's FIRST on your list to kill]].
* MinMaxing:
** Half-elves, having the incontestably ugliest face models in the game and looking like creepy dolls, and being able get limited abilities from classes in which they don't have levels, such as having a pure fighter casting divine scrolls or getting full monk bonus to healing amplification. They're basically a munchkin's wet dream.
** Find a full-cleric with more than 14 intelligence. Go on, ''try''.
** Non-divine Drow spellcasters. +2 to intelligence and charisma? They're popular for a ''reason''. Actually, even Clerics might want to play a drow, since they'll get another turning check.
** Leads to some amusement when a DDO player also plays tabletop D&D, as if they forget which system they're building for they'll turn up with a character sheet that is completely inappropriate for a tabletop game (e.g. a healbot cleric with no strength or combat ability).
* MrSmith: In the quest "Missing", the prime suspect of a series of disappearances is a Warforged wearing a hat named Mister Smythe. [[spoiler: He is actually a Beholder wearing a Warforged costume.]]
* NiceJobBreakingItHero: The defeat of the Black Abbot (Necropolis Part Four) is what sets the events of The Thirteenth Eclipse story arc in motion.
** The following counts, in a way. Inquisitor Gnomon urges you to [[{{Squick}} kill followers of the Sovereign Host, calling them heretics]]. Then, in a more recent update, you accompany him on a trip to a cult base. [[spoiler: Turns out that he's actually one of the "Lords of Dust", and that he used his position in the Silver Flame to distract them from the cult's actions, and to cause damage by attacking innocents and those of other religions.]]
** Another example from the quest "Acute Delirium". After retrieving Belashyrra's Scepter, you must use it to close a Xoriat Portal that was opened earlier. However, it backfires and opens a portal to Belashyrra's prison in Khyber, allowing him to escape. The [[ButThouMust only way to complete the quest]] is to give him the Scepter so that he can wreak havoc upon Eberron.
* NoOSHACompliance: House Deneith's trash incinerator, "The Pit," is a multi-level subterranean building dug out around two [[LavaPit Lava Pits]], which are inhabited by man- and equipment-eating Oozes. The only way to move from one level to the other is to use a network of twisting, railing-less walkways that extend across the lava pits. In addition, the system's "Security System" is really just a series of deadly traps that blast said narrow walkways at 10-second intervals. The system is electrically powered, and the circuit breakers inexplicably channel the electricity through the room they're housed in. In addition, if you turn the trash incinerating furnaces on in the wrong order, you'll blow up half the city. (You can't do this because the rooms unlock in order, but it's [[AllThereInTheScript stated in the quest introduction]])
* NotTheFallThatKillsYou:
** Using a Feather Fall spell or wearing a feather-falling item lets you avoid falling damage. So does [[LiteralCliffhanger grabbing a ledge or ladder]] or [[SoftWater landing in water more than 7 feet deep]].
** The Monk class gets off easier here with their Slow Fall feat that's automatically given as they level. By the time they are level 20, they can fall ''any'' distance [[MagicalRealism without any damage]], Feather Fall item or no.
* OneHitKill: Any of the dozen or so death effect spells, like [[NamesToRunAwayFromReallyFast Finger of Death, Destruction, and Implosion]]. The Grandmaster of Flowers epic destiny also has the power "Everything is Nothing," which allows you to quite literally ''rip your enemies out of the multiverse'', [[CaptainObvious killing them instantly]]. Should the save be made, they still take 1000 points of damage, and must save ''again'' in order to reduce that damage to 500. Bosses can't be blown out of reality, but they do take the damage.
** There are also vorpal, slaying, banishing, smiting, and disruption weapons that kill most mooks of the appropriate type outright or deal a thousand bonus damage to others.
* OpeningTheSandbox: You leave Korthos and get to Stormreach, and BAM! Look how many quests are suddenly available to you! Then, you play through all the free stuff, and if you decide to upgrade to a premium account, look at how many MORE dungeons you can [[BribingYourWayToVictory buy]]!
* OptionalStealth: A low-level quest is called "Stealthy Repossession", and involves stealing a special gemstone back from kobolds without killing more than a few kobold prophets. Appropriately built classes can sneak the entire way through, but other classes have little choice but to madly blitz through the dungeon, or else play normally but carefully kill every kobold except the prophets. A handful of other quests become easier with some stealth, but are never impossible without it.
* OurDwarvesAreAllTheSame: Short, bearded, gruff people who like beer and digging. Except perhaps for the Duergar, who will kill you on sight.
** Oddly, most NPC dwarves in Stormreach have no facial hair at all and are quite polite. The lore for them plays this straight, though.
* OurElvesAreBetter: Playing a drow for any non-melee-combat-specialized class is what you might call optimized, since they receive more bonus stats than they lose (all other races' stats balance out).
* OxygenMeter: Used when you swim. Wearing an amulet or ring of Underwater Action gives you SuperNotDrowningSkills.
** Warforged have SuperNotDrowningSkills as a racial ability: They don't have lungs, and therefore don't need to breathe.
** Unfortunate players may often find their chest loot filled with [[UselessItem Underwater Action items that are racially restricted to Warforged.]] Thankfully, players now have access to an ItemCrafting area to crunch these things into a fine powder.
*** Or just have a high enough Use Magical Device score to ignore the racial restriction.
* PoisonIsEvil: The Spinner of Shadows has poison so deadly that death is certain without the help of an ethereal flame inside her prison. Other enemies have some nasty poison attacks. Averted with the Ninja Spy and some spell casters, who use their poison on the side of good.
* PhysicalGod: Lolth, who managed to smash a hole in reality between Eberron and the Forgotten Realms, breaching Silver Flame wards in the process. Also, the top few members of the [[LegionsOfHell Devil Legions]] could qualify, since while not actually gods they are immortal beings of incredible power.
* PlatformHell:
** "The Pit" quest, again. Two rooms involve platform puzzles. One involves running around on pipes while jets of steam push you backwards and fire elementals shoot at you, but is relatively easy if you are prepared for it. The other one involves co-ordinating at least four team members, two of whom must be simply ludicrous at platforming (jumping some 15 feet horizontally to catch some crosswise pipes and pull yourself up) while your friends on the ground deal with equipment-eating oozes that respawn indefinitely while manipulating the correct valves for the platforming team. Also, if you get hit while using a valve, your action stops. Oozes are immune to almost all status effects and most elemental magic ([[ColourCodedElements varies by color]])? Oh, and watch out for the hobgoblins with bows, and the room at the top that's full of exploding barrels [[spoiler: an ooze drops down in that room and tries to attack you, occasionally igniting the boxes]].
** As stated above, "The Coalescence Chamber." You have to navigate up a winding spiral of narrow ledges while being assaulted by troglodyte snipers and sorcerers. The real pain in the ass here is that jumping will sometimes cause you to be pushed away from the ledge, resulting in a hair-tearing plummet all the way back down to the bottom. Note that it's usually impossible to make your way back up without help from fellow party members because the monsters respawn.
** "The Tear of Dhakaan" also has a couple platform sections... with most of the platforms ''trapped''. Imagine the surprise of many players who, going in for the first time, realized that their first leap landed them in the middle of an acid spewer.
* PrestigeClass: Just a few of them, and they aren't technically [[ClassAndLevelSystem classes]], but you can use your action points from levelling up to specialize in one of your class' abilities.
** The Underdark update added Epic Destinies, "mini-classes" that provide powerful abilities, which are available to characters level 20-25.
* PurelyAestheticGender: Naturally, this causes several male players to create female characters.
* ReligionOfEvil
** The Devourer cult on Korthos.
** The Dark Six cult on Sorrowdusk.
** The Vulkoorim in Menechtarun, a group of drow who worship the scorpion god Vulkoor.
** The cult of the [[AGodAmI Black Abbot]] in the Necropolis.
** The cult of the [[SealedEvilInACan Spinner of Shadows]]
** The PathOfInspiration.
** The Lord of Blades cult.
*** Interestingly enough, the ''player'' can be a follower of this cult as a Warforged. These include Warforged [[ThePaladin Paladins]]. Who are like every other paladin, paragons of goodness.
** The cult/empire of Lolth.
** It's easier to count the religions that ''aren't'' this, actually.
* RepeatableQuest: Adventures are infinitely repeatable on four different difficulty levels each. The first play on each adventure/difficulty combo gives an array of experience bonuses, while subsequent replays start adding penalties, eventually hard-capping the XP gain at a very low number for extreme repetition. Ironically, it's more efficient to not repeat quests too heavily (except for crafting purposes).
* ResurrectionSickness: The effects of death will cause more hardship on your spirit (and poor gameplay) if you die repeatedly.
* RougeAnglesOfSatin: To be expected in a "free" MMORPG where one of the playable classes is a rogue.
** Most commonly seen misspelling in the game's Groups window where help for quests are asked. ''"How much damage does my powder puff do, again?"''
** Just to be funny, the developers created a quest chain giver in House Phiarlan (a village of elven performers ''cum'' spymasters) named "Rouge".
* ScarsAreForever: Some of the appearance customization are a scar somewhere on the face. Naturally, nothing short of reincarnation (basically reroll, but keep used tomes, equipment and levels) can remove it.
* SealedEvilInACan: There are several boss monsters that are or were imprisoned in some fashion. Three of them are arc villains, and can be [[DidYouJustPunchOutCthulhu punched out]]. The Devourer cult at the beginning of the game tries to release a "Devourer beast" that cannot be punched out, meaning that you have to reverse their efforts to thaw it out. The Spinner of Shadows, sealed for eons in the plane of Khyber, is another canned boss that led to a MUCH more powerful goddess.
* SelfImposedChallenge: [[http://www.massiveonlinegamer.com/news/usersubmitted/155-perma-death-in-ddo The Perma-Death Challenge.]]
* SentryGun: Magefire Cannons, and to a lesser extent, the Artificer's Flame Turret spell.
* ShatteringTheIllusion: The first section of the "Partycrashers" quest takes place in the Phiarlan Illusionarium, which is packed with illusionary enemies and traps that [[YourMindMakesItReal can, and will, hurt you.]] The only way to get past them is to destroy the Dragonmarks of Shadow that created them.
* ShootTheMageFirst: Killing the casters first is a good rule to follow, given the general danger of spellcasters in D&D in general.
* ShoutOut: Stuffed to the gills with them. From Music/HeavyMetal references all over the place such as a [[Music/{{Scorpions}} scorpion boss named Schenker]] to a quest called [[Music/VanHalen Running with the Devils]] to a bard themed sword with the enscription [[Music/{{Rush}} Anthem of the heart; Anthem of the mind]] to Franchise/StarWars flavored quotes in NPC text to {{MythologyGag}}'s to other D&D properties (for example, in the quest Fear Factory there's an optional locked door behind which first you find [[spoiler: a dead Acrobat. Further down you fight an undead Cavalier, Ranger, Magician, and Barbarian. Popular theory is the Thief sold them out.]] Makes the [[spoiler: end of {{WesternAnimation/DungeonsandDragons}} ]] a bit HarsherInHindsight.)
** For an exhaustive list check out this thread: https://www.ddo.com/forums/showthread.php/364243-Easter-Eggs-and-Puns-in-DDO
** There's a new raid featuring three weapons named [[WesternAnimation/MyLittlePonyFriendshipIsMagic Nightmare, the Fallen Moon, Celestia, Brightest Star of Day, and Twilight, Element of Magic]].
* SlipperySkid: Throw your Grease spell and players with low Balance skills begin a series of {{Pratfall}}s. This might also get you kicked from the party if you do this against enemies that rarely [[IncrediblyLamePun fall for it]] during battle.
* SquishyWizard: Even with 20 extra hit points at start, it's still not a good idea for most sorcerers or wizards to get into melee, especially at lower levels.
* SteamPunk: Considering [[{{Eberron}} the setting]], the game has this and DungeonPunk all over the place, from the low-level The Waterworks and Shan-To-Kor, to the advanced adversaries in the Cannith Manufactuary. The Menace of the Underdark expansion, however, sticks to the high-fantasy campaign settings when you visit the Forgotten Realms.
* TalkingIsAFreeAction: Ehh... kinda. If you have a microphone, you can talk to your party while you play (sound quality varies). If you stop in the middle of combat to ''type'' to your teammates, you're likely to die unless your cleric is particularly competent.
** Subverted when fighting a boss or mini-boss with dialogue, whom you can kill before they're done with their {{Monologuing}} or EvilGloating. Nothing says ShutUpHannibal like a Holy Burst greatsword to the face.
* TakeThat: [[MapleStory Broccoli]] [[http://www.youtube.com/watch?v=hhIMu60Zab0 or the Beholder]]?
** There's rumors that they are making the Broccoli a playable class with veggie themed attacks.
** There's a quest-giving NPC that asks you to [[WorldOfWarcraft retrieve 10 rat tails]]. When your character reacts incredulously ("You can NOT be serious!"), the NPC's whole table bursts out laughing. He then gives you the REAL mission.
* TheCanKickedHim: EnforcedTrope. A challenge named Moving Targets has an optional objective of killing a boss in the toilets.
* TimeTravel: The Chronoscope Raid, where you go back in time to the Devil invasion in the Stormreach Marketplace.
* TooDumbToLive: Somehow Tremas got it into his head that it would be a good idea to kill a powerful devil by aging him to death. Devils are immortal, and since Tremas is a tiefling there is no reason why he would not know this (having likely worked with them for his ''entire adult life''). He still acts surprised when it fails, though.
** The Delirium and Acute Delirium quests were caused by an apprentice who wanted to show off to his girlfriend with a scepter created by the Lord of Eyes, the Daelkyr Prince of Madness. You can guess what happens...
* TheUndead: They tend to be GoddamnBats to rogues, because a +5 Holy Shortsword of Disruption is a mite costly at lower levels (and can't be used anyway until [[TookALevelInBadass you're MUCH higher in character level]]).
* {{Understatement}}: After you destroy the Quori Mindsunder in "Misery's Peak," the Dungeon Master notes that the dragon you just freed from its power looks "very annoyed" -- as she uses her ice breath on the Mind Flayer that had her under its thrall and [[LiterallyShatteredLives turns it into a popsicle]].
* UnusuallyUninterestingSight: Fred, the resident EldritchAbomination brain-eater/feat retrainer.
* UpToEleven: Due to the recent expansion, the Epic difficulty has been divided into four difficulties.(Epic Casual, Normal, etc.) The old Epic mode was between Epic Hard and Epic Elite in terms of difficulty. Epic Elite is somehow much more challenging than the old Epic mode, with dogs that can kill you in less than 5 hits, and traps dealing absurd amounts of damage. Now, imagine fighting the [[ThatOneBoss Lord of Blades]] on Epic Elite...
* UselessUsefulSpell: Plenty of them:
** Anything that does stat damage often takes a lot of hits before it may become effective.
** Turn Undead, which can incapacitate or destroy targets but seldom works on anything powerful enough to be worth fighting in the first place.
** Fear, which mostly causes weak enemies to run away and thus take longer to kill.
** Bosses, of course, are largely immune to stat damaging, along with all other forms of instant death, level drain, paralysis, charm, stun, petrification, knockdown and immobilization.
** As an inversion, however, several of these effects are highly useful against anything that isn't completely immune.
** Enhancements, spells, and item effects can be used to increase stat damage effectiveness, especially with poison in the last 2012 updates.
* VancianMagic: Played straight on points one (spells do one thing and only that one thing) and three (spell levels, caster levels, must rest to recharge spells), averted on point two: spellcasting players have a ManaMeter.
* VillainBall: [[TheDragon Suulomades]] apparently grabbed this while planning his attack on Stormreach. As opposed to simply waltzing through a city where not a single living soul is strong enough to take him on, he sends an army of mid-level Mooks to do his dirty work while he was back on Shavarath. This resulted in the devils losing the battle when it could have been won with very little effort.
** Tremas also does this when he tries to kill Suulomades by [[TooDumbToLive aging him to death]]. Suulomades then does it again while overlapping with LawfulStupid by taking Tremas to Shavarath to face the prescribed punishment (torture) instead of entering a battle that his much weaker minions are losing.
* VillainForgotToLevelGrind: Averted. Malicia is the main antagonist of a level 5 story arc, and is also the main antagonist of a level 18 quest. In both cases she is of a higher level than the characters.
* ViolationOfCommonSense: "The Pit," yet again. Often the general strategy of the Pit, when going from up high to a lower point, is to ''jump off'' and use your feather-falling boots to survive, and steer yourself to the next area. Jumping off cliffs as shortcuts in general tends to be this.
* WalkOnWater: Before late 2012, you could become a Monk, choose the Path of Inevitable Dominion (dark) path, choose the right enhancements and eventually gain the ability to focus your ki to walk (well, ''run'', really) on water (''and'' lava, but you might still take damage). Your [[TheDestroyer Remo Williams and Master Chiun dreams come true]]. But now, that ability has been lost to major game changes.
* YouAllLookFamiliar:
** Inverted. The {{NPC}}s are fairly varied... it's the player characters who tend to all look the same.
** The enemy [=NPCs=] (i.e. monsters) will all use the same character model. Any given batch of cultists will look an awful lot like any other given batch of cultists.
** The final quest of Korthos Island has the player (or player in front, if in a party) turn a corner to see several cultists dressed in all white marching in a 2x3 formation. All identical down to walking in step.
* YouHaveToBurnTheWeb: Some of the earlier quests involve webs that block your progress. You can get through them with a cutting weapon, a flaming weapon, or a fire spell... [[FridgeLogic Or any other mundane weapon, or your fists, or any kind of attack spell]]. It's worth noting though, that the webs WILL simply shrivel away if you light them on fire.
** The actual Web spell can be burned away with a fireball or burning hands spells or some other fire area effect.
** Some higher-level quests have web curtains which cannot be burned or damaged in any way, but as soon as you kill the spiders involved, the webs part obligingly.
* ZergRush: Kobolds and zombies are fond of this tactic. There is a quest where the player must kill 200 kobolds, who come in large waves.
** Another quest cranks this up where you have to beat 200+ hobgoblins and bugbears, which are ''significantly'' more of a threat due to almost half of them being casters and require strategy rather than brute force to thin out. The last wave contains ogres.
