"Diablo 4 Devs Tease the Legendary Cow Level's Return"

Diablo 4 developers dropped a hint about the highly sought-after Cow Level during an interview at BlizzCon 2023. Players can earn three "Items of Great Significance" by killing 666 cows, which can be used to craft a key to access the Forlorn Hovel, where the portal to the Cow Level is believed to be hiding. The first expansion for Diablo 4, called Vessel of Hatred, was also announced, set to arrive in late 2024 and featuring a new Diablo class.
