Diablo 4's Vessel of Hatred has a lot going for it with its introduction of an original story and the Spiritborn class, but the new Nahantu region is one of its most appealing features from a visual standpoint, at least. Originally from Diablo 2, the Nahantu region offers players something much more than Diablo 4's Sanctuary has been able to, and it's a step in the right direction.
