The Diablo franchise is a dark fantasy action role-playing game franchise by Blizzard Entertainment. It is not related to the Warcraft universe in any way, nor are there significant contributions from that universe to this one. Although, there have been some rumors of more linkage.

Diablo II

Diablo III

Diablo IV

Many people suspected that the Diablo franchise was dead when Blizzard closed Blizzard North (the studio that created it) after the release of the last Diablo II. The franchise continued as Diablo III which was announced at the Blizzard Worldwide Invitational 2008 in Paris, and eventually was released in 2012. Diablo Immortal, originally a mobile-only game in the franchise, was announced at BlizzCon 2018 to poor reception and was eventually released in 2022 with a PC port but with a heavy focus for mobile. Diablo IV was announced at BlizzCon 2019 and released in mid-2023.

Influence on and differences from Warcraft

Humorous references aside, many spells and abilities in WC3 and WoW were inspired by skills in Diablo II, namely auras and the idea of passive skills. The RPG elements of Diablo were significant in the development of WoW, as it meant that Blizzard already had experience in building an RPG. Here are some of the similarities that players may notice between games:

The Barbarian of Diablo II features a variety of buffs in the form of battle cries, which most likely inspired the Warrior's Shout abilities. (One of which was the ability to Shout in Diablo.) Most if not all of the shouts in WoW have a counterpart shout in Diablo.
Barbarians in Diablo II could dual wield two-handed weapons, identical to the [Titan's Grip] of Warriors in WoW.
Barbarians in Diablo II have the skill Whirlwind identical to the Warrior skill [Whirlwind].
Several of the Mage's spells are taken directly from the Sorceress, including [Mana Shield], [Frost Nova], and [Frost Armor].
The Rogue's combo point system is similar to that of the Assassin's charge system in which players could accumulate charges and unleash finishing moves whose powers depended on the number of charges the player has. The Assassin also features a series of damaging traps, like the Hunters of WoW.
Druids from Diablo II can shapeshift into Werewolves and Werebears.
Paladins in Diablo II have numerous auras. They also have the [Charge] ability, which in WoW belongs to the Warrior.
The Necromancers in Scholomance and Stratholme use the Bone Shield spell and can raise skeletons, both of which Diablo II's Necromancers have.
The [Bone Shield] ability of Death Knights has a similar animation and function as the Bone Armor spell of Necromancers in Diablo.
Socketed items were first introduced in Diablo II and later applied to World of Warcraft.
The Murkalot pet is themed after the new Crusader class in the Diablo III expansion, Reaper of Souls.
Thunderfury and Ashbringer also exists as items in the Diablo setting.
The Mage Clan Wars possesses many story similarities to the War of the Ancients
The Mythic+ system and Torghast, Tower of the Damned are based on the Greater Rifts from Diablo III.
The Threads of Fate leveling mode in Shadowlands is similar to Adventure Mode in Diablo III.
The Companions skill line for Demon Hunters in Diablo III takes the skeleton rigs of most of the animal companions from World of Warcraft; specifically the wolf, ferret, and boar. In the case of the boar, the model is a direct rip from World of Warcraft.

Like in the Warcraft universe, Diablo features demons, but unlike Warcraft, Diablo's demons are ruled by devils, come from Hell, and fight a war against actual angels. The more traditional nature of Heaven and Hell make the world of Diablo extremely different from that of Warcraft. Religion becomes a conflict (references are made to Mage Wars and Inquisitions), and humanity becomes pawns in a greater conflict between angels and demons. In World of Warcraft, the fight for fame and glory can be tied into a quest to save the world from the evils of the Old Gods or the Burning Legion. In the world of Sanctuary, no quest for prestige and riches can occur without facing the minions of Hell.

In terms of visual style, Diablo is on the opposite end of the visual spectrum from Warcraft.^[1]

[Band of the Hierophant] references a legendary ring, the Hierophant's Seal in Diablo II.

[Livestock Lochaber Axe] that drops from The Cow King may be a reference to the Bovine Bardiche in Diablo III which was used to create the portal to the secret cow level.

Locations

Stone Cairn Lake in Elwynn Forest is a lake with an island at the center that has five stones arranged around a memorial. This is a reference to the Five Cairn Stones, an area in Diablo II where you open a portal to Tristram in Act I.
[Cow King's Hide] is a reference to the Secret Cow Level, the Moo Moo Farm, in Diablo II, which contained Hell Bovines and the Cow King.
Diablo II contained a secret level where one had to battle hordes of insane bovines, including the extremely powerful Cow King. This level was built into the game after a fake screenshot was posted of a secret cow level supposedly in the first Diablo game. A saying once existed in the loading screen tips in World of Warcraft that said: "There is no cow level." (The saying was also a cheat in the game StarCraft which caused you to automatically win the round.)
- Diablo's 20th Anniversary event introduced the "secret cow level" into World of Warcraft for a limited-time. There were several Diabolic Taurens and Diabolic Bovines roaming a farm and The Cow King also made an appearance. During the event, demonology warlocks had their Wild Imps appear as a Mini Diablo.
[Tristam Legguards] is named after Tristram, one of the most important locations in all Diablo games.

NPCs

The achievements [A Worthy Opponent], [Could We Find More Like That?], and [Glorious!] are quotes from Kormac the Templar in Diablo III after a rare or champion mob is slain.
Kaganishu, a kobold in Borean Tundra, is a play on Rakanishu from Diablo II. Similar to the Diablo boss, the nearby NPCs will scream out his name in all caps in combat.
Razorclaw the Butcher in Shadowfang Keep references the iconic early boss of the same name in Diablo I, brought back as the Act I boss in Diablo III: The Butcher.
Tyrael Flamekissed is a General Goods vendor at the Shattered Sun Offensive.
[Maiden's Anguish], formerly used by rogues to brew poison, references Andariel, the Maiden of Anguish. She was the first act boss in Diablo II and had a nasty Poison Spray ability.
[Stay Awhile and Listen] is a reference to dialogue from Deckard Cain in Diablo I.
The Treasure Goblins from Diablo made an appearance in World of Warcraft during Diablo's 20th Anniversary and once more with the A Greedy Emissary event.

Other

In reference to his demonic form in Frozen Throne, one of Illidan's gag quotes is "Wings, horns, hooves...what am I saying, is this Diablo?"
Another common humor reference to the Diablo franchise is the mention of Wirt and his wooden leg. Wirt was originally an NPC character in the first Diablo game, filling both the role of a rare-item vendor and a quest giver. It is believed Wirt was killed when Diablo's minions overran the NPC town of Tristram. In Diablo II, it was a requirement that the player needed to combine Wirt's Leg with a Tome of Town Portal in order to gain access to the Secret Cow Level. In Warcraft III: The Frozen Throne, an item called Wirt's Other Leg could be found in one of the campaign levels after defeating the Butcher, a giant abomination named after an early boss in the original Diablo. In World of Warcraft, there are several items that are named after Wirt's wooden leg including [Wirt's Fightin' Leg], [Wirt's Haunted Leg], [Wirt's Last Leg], [Southsea Lamp] (formerly named Wirt's Third Leg), and an object Wirt's Gambled Leg.
