Diablo 4's Vessel of Hatred expansion has a lot of strange selling points: it's a continuance of the main story surrounding Mephisto and Neyrelle, it takes players to the historied jungles of Nahantu, it adds a brand new class in the Spiritborn, and it expands the game with a plethora of new items, expanding mechanics, and more. Of course, a lot of eyes are on the Spiritborn because it is the first brand-new mainline Diablo class in a long time (discounting the Tempest in Diablo Immortal).
