20 years of Diablo is also being celebrated in World of Warcraft. A secret cow level holds plenty of rewards.
It has been exactly 20 years since the first Diablo was released and excited hack & slash players. Blizzard is celebrating this significant event in various ways, including in the parallel world of World of Warcraft.
The cow level has always been a joke known to Diablo players. At one point, there was even a tip on the loading screen in WoW that said “There is no secret cow level” – and as of today, that tip is a blatant lie. Because to celebrate Diablo’s 20th birthday, there are now plenty of festivities and hidden features in World of Warcraft – such as the legendary cow level!
To enter the cow level, you must first locate a Treasure Goblin. This can appear in several places in the game world, known locations so far include the shadow side of Dalaran (the sewers), the Broken Isles, and at the end of instances of all difficulty levels. Once the Treasure Goblin appears, you must beat it down as quickly as possible, because it tries to escape through a portal. If successful, a portal to the secret cow level will appear instead! This is located in an instanced version of Duskwood, and – as expected – you must kill cows in the form of Tauren and other creatures there, including the Cow King.
As a reward, there is the toy “Twelve-String Guitar”, but also plenty of other things. Not all details of the event are known yet, but players are discovering every secret.
There are also other small references to the birthday. Warlocks currently cannot summon wild imps, but instead a horde of mini-Diablo.
