History YMMV / DungeonsAndDragonsOnline

* SugarWiki/HeartwarmingMoments: GaryGygax, co-creator of the original DungeonsAndDragons game, actually narrated one quest arc, Delara's Tomb. After Gygax's death in 2008, the developers of DDO created an in-game memorial in Delara's graveyard (which includes a d20 dice on the stone memorial). A similar memorial appears in the Threnal quest chain for D&D co-creator Dave Arneson, who narrated that quest series.

** "Kobold Assault" gets this for being the first Challenge Dungeon most players meet, It's a massive ZergRush of Kobolds, including their spellcasters, You have one rest shrine, it is also out in the open, this tends to involve players getting hopelessly overwhelmed even on casual.

*** Also, there are 3 rooms almost completely filled with acid, and you either need to navigate across pipes on the ceiling or jump on small platforms to the other side to pull a lever, causing walls to go up IN THE POOL, making it so you need to return a certain way. I forgot the third one, though. Also, there's a room with acid in front of the staircases, as well as an earlier room where you will likely need to walk across a pool of acid, so your hireling will probably walk into the acid, killing him/herself.

** Gnarkill, Troll Butcher in the Waterworks area is the first troll parties are likely to encounter. His regeneration combined with heavy damage-dealing capabilities make him difficult for parties that do not know to use fire or acid. Considering that flaming and acid weapons are not common at low levels (Perceptive people might notice the very helpful flame trap with a pressure pad on the right side of the room)...

*** On Normal, his Challenge Rating is the highest in the game at 32. This means he is twelve levels higher than the current level cap. On Epic, his CR is '''46'''.

*** Also, due to the new expansion, Epic mode has been divided into four difficulties.(Epic Casual, Normal, Hard, and Elite) Epic Hard is usually much easier than the old epic, but Epic Elite is [[HarderThanHard even harder]] than the old [[UpToEleven Epic difficulty]], meaning that the Lord of Blades [[BeyondtheImpossible is even tougher than before.]]

* 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...

**** The third pool of acid has ''[[ThereIsNoKillLikeOverkill spinning blades in it]]''.

The Lord of Blades. He is a handful on the lowest available difficulty setting and {{harder than hard}} on Epic. On Normal, he has ~200k hitpoints (about as much as several raid bosses have on Epic), 80% fortification with a such a massive fortitude save that he is pretty much sunder proof, has several devastating AOE attacks which are capable of instantly killing almost any character if you do not evade them (requiring twitch skills), and the fight goes in several phases which involve periodically clearing minibosses while still enduring LOB's powerful attacks.

* DemonicSpiders - Kobold Shamans on elite mode know lightning bolt spells. And use them a lot. Failing a reflex save means bye-bye to half of your health if you're a fighter, or all of your health if you're a wizard. At higher levels, you meet beholders, one of the game's nastiest monsters who tend to repeatedly use a Disintegrate spell from their EyeBeams, which is likely to kill you in one shot as well as damage or destroy all of your costly equipment.
* GoddamnBats - The actual bats are hard to hit if you aren't using auto-target, and auto-target is slower than the manual mode. Go figure. There's also rust monsters that pretty much have to be dealt with via ranged weapons, a wooden club, or magic (they eat metal), oozes that similarly eat whatever hits it other than ranged weapons and are best handled with GoodOldFisticuffs or a rare crystal Muckbane club, spellcasting enemies that know Hold Person/Hypnotize/Daze Monster, trolls that have to be [[KillItWithFire finished off with fire]] or acid (unless you have epic damage output), the large spider enemies that keep jumping around when they attack, etc. etc.
* ThatOneBoss - Numerous examples.

* [[ThatOneLevel That One Dungeon]]

** First General Horoth in the Tower of Despair raid has around 2 million health, hits hard, and regains 20% of his health if a party member dies. He also has a move that will kill all party members who are not wearing Boots of Anchoring, and will stun those who are for a short time.
*** Note that his "kill all unless wearing boots" attack doesn't actually kill, it will literally BANISH those not wearing them back to Stormreach, denying them completion of the raid and the resulting quest loot.

* [[ThatOneLevel That One Dungeon]] - "Proof is in the Poison" is very much a nightmare for any low-level party that does not know what they're doing, mainly due to the many casters in the dungeon that like to throw nasty spells on you. The Quickfoot Caster ambush on the bridge at the beginning has led to many a TotalPartyKill.

* YourMileageMayVary - Lots of people enjoy this game. Fans of the original tabletop game? Tend not to.
** Also, The Pit. It's a long run, and you spend 2/3rds of the time walking through force traps, but it gives '''lots''' of experience and the loot isn't too shabby.
