History YMMV / Diablo

* {{Altitis}}: The series was ''born'' for this. Much of the appeal comes from taking its simplistic gameplay style and sprucing it up through constant character customization. Shifting between characters and character builds are a sure-fire way to fall prey to the game's [[JustOneMoreLevel infamously addictive nature]].

* TierInducedScrappy: Blood Star is pretty underwhelming for an endgame spell that you can add to the spellbook. It's supposed to be the answer to use against enemies that are immune to Fire and Lightning due to Blood Star being a Magic-type attack that enemies are very rarely immune against, but the fact that the spell costs both mana ''and'' health to use along with the damage Blood Star deals not being all that high makes it too much of a hassle compared to just relying on the much easier and stronger Fire and Lightning spells along with just using basic weapon attacks. It's also been found to be much easier to just Stone Curse spam the enemies as an alternative Magic-type spell for said Fire and Lightning immune enemies. The reson being that while constantly freezing enemies with Stone Curse is very mana costly, that can easily be rectified by just stacking up on Mana Potions.

** Turns into a bit of Tear Jerker with [[spoiler:Deckard Cain's death in ''III''. We never listened...]]

* FanNickname: Combines this with MaliciousMisnaming. The immense hatred towards ''Diablo Immortal'' and what it stood for a majority of gamers caused them to just omit the 't' and instead call it ''Diablo Immoral'[[note]]Creator/CarbotAnimations wouldn't be [[WebVideo/{{Diablol}} the first/only one]] to use the term.[[/note]]

** Unofficial ExpansionPack ''Hellfire'''s easter egg bard was breakable without any bugs because of dual-wield. Just equip a haste/peril weapon combo together with an undead crown or helm or spirits for life-steal. Because peril does 1x WEAPON damage to the user, but 3x CHARACTER damage to the monsters, and such big life-steal will almost always get your HP back, such a combo can potentially cause total havoc.

* BestLevelEver: The Hell Levels. The most atmospheric hell ever (if you prefer {{Gorn}} hell over firey hell), and you [[DidYouJustPunchOutCthulhu fight the Devil]] at the end.

* {{Adorkable}}:
** Tyrael has his moments as a human. In ''Diablo III's'' Adventure Mode, he has yet to get used to certain basic things mortals have to do that angels don't, such as eating - one [[WelcomeToCorneria awfully common conversation]] he has with Lorath Nahr involves getting a stomachache from eating his entire daily ration in a single meal. Since Adventure Mode takes place after [[spoiler:defeating Malthael]], Tyrael's struggles become [[{{Irony}} ironic]] as Tyrael [[spoiler:is the Archangel of '''Wisdom''']], yet makes that mistake.
** While Kormac's usually a confident, [[LargeHam hammy]] BloodKnight KnightTemplar, he gets rather awkward and embarrassed with regards to the opposite sex. He (poorly) denies his attraction to Eirena, [[spoiler:requires the PC's pushing him forward the entire way to try to ask Eirina to stay with him (and then words it instead as just adventuring with him which might have caused Eirena [[ObliviousToLove to not get the entire implication of his question in spite of responding yes]])]], and random dialogue in Act II can have to PC ask if there are any women in the Templar Order which he admits there isn't, causing Leah to rhetorically question "Shouldn't the Templars accept anyone willing to fight evil"? aggressively, with Kormac responding meekly that's a grand idea which he should mentions to the Order's higher-ups.

** Monsters that attack using Blood Star. Due to the game's dearth in providing substantial defense towards the generic "MAGIC"-type damage (ie Bone Spear, Berserk, Blessed Hammer etc) for players, a frequently-encountered stream of blood stars will cause ''immense'' grief to characters that don't explicitly load up on hit points and the mod "Magic Damage reduced by [''integer'']".

** Literal bats...that teleport. ''Diablo II'' adds Flayers, Maggot Young, Flesh Beasts, Leapers and Imps. The Imps teleport. Both games have Fallen/Carvers. Flayers, Fallen, and Carvers all tend to swarm and can be resurrected by their respective Shamans (except for the undead Bone Flayers, which ''explode'' for a nasty chunk of damage when they die). Sand Maggots and Flesh Beasts spawn Maggot Young and Flesh Spawn, respectively. Imps are spawned by huts. Leapers move very fast and jump all the time which makes them difficult to kill due more to being hard to click on than having lots of armor or HP.

* MagnificentBastard: [[PersonOfMassDestruction Baal, Lord of Destruction]], is the middle brother of the Prime Evils and [[UnderestimatingBadassery far more clever]] than he is typically given credit for. More straightforward than his wantonly sadistic siblings, Baal was the first of them to suspect his niece Lilith's theft of the Worldstone. After following the Dark Exile, Baal emerges thanks to manipulating the wandering patsy to Diablo Marius into freeing him, later appearing to him as the angel Tyrael so that Marius will surrender his Soulstone to him before he executes Marius as a "reward" and proceeding to go on to corrupt the Worldstone to [[TakeOverTheWorld seize control of the world]].

** You've found a Horadric Staff! That's quite a treasure you have there in your Horadric Cube! I'M DECKARD CAIN!

** Diablo 2: Disconnected[[labelnote:Explanation]][[UpdatedReRelease Diablo 2: Resurrected]] has been the subject of mockery on release due to the unstable servers, leading to several emergency maintenances and loads of technical issues, resulting in people being unable to play online the game [[https://www.reddit.com/r/Diablo_2_Resurrected/comments/q6mivl/30_expansion_confirmed/ and mockingly refering to the game by this moniker]][[/labelnote]]

*** The same can be said about Level 3's "King Leoric" if the player doesn't choose to spam the Holy Bolt spell, or doesn't have access to said spell.

** [[SatanicArchetype Al'Diabalos]], better known as [[AntagonistTitle Diablo]], is known as [[TheDreaded the Lord of Terror]]. Before the events of the first game, Diablo fought alongside his brothers, Mephisto and Baal, against the Angiris Council in the Eternal Conflict, at times [[ItsAllAboutMe even fighting his own brothers to gain more power for himself]]. With the discovery of Sanctuary, Diablo sought to [[TheCorrupter corrupt]] humanity to his will, deliberately [[TheChessmaster engineering]] his and his brothers' own exile from hell into Sanctuary so they could corrupt humanity. Through this plan failed due to the intervention of the Horadim, Diablo's essence possessed King Leoric of Tristram 200 years after his imprisonment and later [[DemonicPossession took possession]] of Prince Albrecht once he deemed Albrecht a suitable host. Through defeated by Albrecht's brother, Prince Aiden, Diablo corrupts Prince Aiden into the Dark Wanderer when the latter sought to contain Diablo's soulstone within himself, and procreated Leah with Adria as a means to [[BodyBackupDrive revive himself should he be slain again]]. As the Dark Wanderer, Diablo destroyed Tristram with a horde of Demons and sought to free his brothers and unleash them into Sanctuary in order to corrupt the Worldstone and subsequently humanity, manipulating Marius into helping him free Baal. Through defeated and seemingly banished to the black abyss, Diablo reemerged 20 years later due to Adria's manipulations of another group of adventurers to empower the Black Soulstone and restore Diablo into Sanctuary into a form combining the power and essence of all the Great Evils. Ultimately, Adria's manipulations succeeded at restoring Diablo at the cost of Leah's life, and he [[HellInvadesHeaven ascended to the High Heavens to destroy the Angris Council]], causing much destruction before his defeat at the hands of the Nephelim. Driven by a desire to corrupt all of humanity and spread terror across Sanctuary, Diablo stands out as the vilest of the Prime Evils.
** [[SinisterMinister Archbishop Lazarus]], mainly from the first game, becoming a [[PsychoSupporter devoted servant]] of Diablo in Tristram, seeks to bring out the Dark Lord into the real world. Helping Diablo to possess King Leoric, wiping out Leoric's morality and [[TheCorrupter corrupting him into a tyrant]], [[TreacherousAdviser Lazarus plays the devil in his ear]], swaying him into atrocities and even having him start a pointless war that leaves most of his soldiers wiped out by Westmarch. Lazarus then brings the child Prince Albrecht to Diablo to possess, intending on unleashing the Prime Evils to damn and destroy most of Sanctuary, even luring in the well-meaning, would-be heroes to the slaughter at the hands of Diablo's monsters beneath Tristram.
** ''VideoGame/DiabloII'' & ''VideoGame/DiabloIII'': [[TheMole Izual]], [[FallenHero former lieutenant of Tyrael]], [[FaceHeelTurn betrayed the High Heavens]] of his own accord, informing the Prime Evils of the Soulstones meant to contain them and how to corrupt them. Helping them to mastermind their exiles to Sanctuary with all the evil that followed, Izual would become a corrupt demon himself, with the assistance of all the mass bloodshed and death the Prime Evils were responsible for, so that Hell would annihilate mankind in a "tide of blood and nightmare" before moving on to the heavens themselves.
** Maghda and [[spoiler:Adria]] can be found [[YMMV/DiabloIII here]].
** In the novel ''Legacy of Blood'', by Richard Knaak, General Augustus [[NamesToRunAwayFromReallyFast Malevolyn]] shows what kind of man he is by handing a loyal soldier to his witch and mistress Galelona to be [[HumanSacrifice horribly sacrificed to demons]]. Hunting down the armor of his ancestor Bartuc, Warlord of Blood, Malevolyn eventually [[DealWithTheDevil makes a pact with the demon Xazax]], who shows him a ritual to bind demons to his soldiers. Sacrificing the souls of his entire army, Malevolyn has them slaughter a patrol from Lut Gholein before having the city attacked. Despite [[ILied promising them peace]] should he get what he wants, Malevolyn reveals he intends on having Lut Gholein massacred to the last human being before moving on with a demonic army to subjugate or slaughter all before him.

* BreatherLevel: After clearing [[ThatOneLevel the jungles of Kurast]] in Act 3 (the Spider Forest, the Great Marsh and [[IDontLikeTheSoundOfThatPlace the Flayer Jungle]]), it's a huge relief for all players to arrive at Lower Kurast. Players are rewarded with many chests, containers, much easier monsters to deal with and a very smaller area to explore. Not like the previous locations filled with DemonicSpiders like Flayers, Flayer Shamans, Undead Flayers, WillOTheWisp, [[GiantSpider Poisonous Spiders]] and claustrophobic dungeons. That is, until you explore [[HereWeGoAgain the confusing maze-layout of the Kurast's sewers]].

** The Black Death zombies are yellow zombies whose attacks can ''permanently'' reduce your HP upon hit. Rogues and sorcerers can simply pick them off at range, but they are a huge problem for warriors, whose primary attack mode is melee and are often forced to use magic or arrows to kill them without getting close.

* UnintentionallyUnwinnable: The first game has strong {{roguelike}} influences and can screw you over in numerous other ways.
** Black Death in particular take away 1 hit point permanently on striking (with no indication that this is the case) and can render the game unwinnable if you are playing very badly and get hit hundreds of times, leaving you with a tiny amount of health.
** Unless you're a mage who's using Mana Shield... at which point you get to use the ludicrously advantageous "No Stun" bug.
** When you die, the save function is disabled, but not ''immediately''. Yes, saving at this point makes the current game unwinnable. It requires timing by the milliseconds, though. A frame too late and the game disables the save function. The easiest way is probably to get a +HP item and then get yourself down to health lower than said item provides you. When you remove the item, you die. If you click and press ESC almost exactly at the same moment, you get to save without having that item on you. No, there is no time to put it back on.
** It's possible to make the game unwinnable by abusing the Chamber of Bone entrance in a hilariously stupid way. You need to teleport there before you use the book to open it (either with a scroll of teleport or using a scroll of town portal then going there from town) and leave yourself stuck in a sealed room. Yes, you need to be completely stupid to do this unless you're doing it intentionally for the lulz.

* MST3KMantra: This is a requirement. FridgeLogic avoided.

* UnwinnableByInsanity: The first game has strong {{roguelike}} influences and can screw you over in numerous other ways.

** The player is only able to walk, which looks quite weird when your in combat. Come across a spot where there's too many enemies to fight at once? Escape by slowly walking away.
