With the release of Vessel of Hatred, Diablo IV has seen its most significant changes since its original launch in June 2023. Adding a completely new region, Nahantu, along with a wealth of added characters and modes and a brand-new story, the expansion pack is the very definition of a game changer. But it goes even further than that, bringing in entirely new ways to upgrade items, a revamp of the World Tiers, new animal-morphing classes, and a new level cap. However, we meet change without fear, offering a litany of guides to get you up to speed.

For instance, Diablo IV now has NPC Mercenaries you can hire to come with you on your brawling, but you’re only going to find them by following a specific series of quests. Then there are those Spiritborn classes that let you pick between being able to possess the powers of a Jaguar, Eagle, Gorilla, or Centipede…Wait, centipede? No, we’ve checked, that’s definitely correct—and apparently one of the best choices for end-game content.

And this all follows on from piles of massive changes earlier this year, which saw the introduction of loot-fest The Pit, a new way to improve loot called Tempering, the addition of Mythic Uniques, and Infernal Hordes to battle. It’s mayhem!

But worry not, as here we’ve collected every guide we’ve published for Diablo IV’s big changes, which will see you flying toward the new level cap in no time at all.
