October is bound to be a big month for Diablo 4, as the highly anticipated Vessel of Hatred DLC is set to make its way into the game. The impending doom of Mephisto's appearance is promising a harrowing story ahead in Diablo 4, but that isn't the only big addition to the game. A new jungle location known as Nahantu and the compelling Spiritborn class who reside in the land make Vessel of Hatred the biggest update to Diablo 4.
