References to Diablo in Warcraft
- Both Warcraft III and World of Warcraft contain some in-game humorous references to Diablo, for instance, the Cow King's Hide. 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.
- There's a saying in the loading screen/tips in World of Warcraft that says "There is no cow level". This is a reference to the Secret Cow Level
- In reference to his demonic form in The 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 games is mention of Wirt, and his wooden leg. Wirt is an NPC in Diablo I, 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 required to combine Wirt's leg with a Tome of Town Portal in order to gain access to the Secret Cow Level. In 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. Finally, Wirt's Third Leg is an item available in World of Warcraft
- Many spells and abilities in World of Warcraft are derived from 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.
- Barbarians featured a variety of buffs in the form of battle cries, which may have inspired the warrior's Shout abilities.
- 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 had. The Assassin also features a series of damaging traps.
- Just like in Diablo II, Druids possess shapeshifting abilities.
- Paladins in WOW had numerous auras. The Charge ability of the Paladin from Diablo II also belongs to the WOW Warrior class.
- The necromancers in Scholomance and Stratholme use the Bone Shield spell and can raise skeletons, both of which Diablo II's Necromancers have.
- Socketed items were first introduced in Diablo II and later applied to World of Warcraft.
- Diablo features an eternal war between the forces of the High Heavens and the Burning Hells. Warcraft has its own demons in the form of the Burning Legion and those who oppose them serving the Holy Light, such as the Naaru.
- The Light carries the same name in both universes, and operates in much the same way, sanctifying paladins and uniting the people of Sanctuary (even Necromancers) or Azeroth (even Warlocks) against their common foes.
