Vessel of Hatred Datamining: New Spiritborn Class, Mercenaries, New Skills for All Classes, and More

Stan Avatar by Stan

Datamined details from the upcoming “Vessel of Hatred” expansion pack, set for release later this year, have surfaced, revealing exciting updates including a new Spiritborn class, Mercenaries, new skills for all classes, and much more!

About four months ago, a datamining scoop on “Vessel of Hatred” took Reddit by storm. It detailed how Blizzard inadvertently uploaded the “Vessel of Hatred” build onto the same server branch used for last year’s endgame beta. This slip-up meant anyone who took part in the endgame beta had the chance to download the client. Though mining data without Alpha access is tricky, this glitch made it feasible to sift through individual file names, shedding some light on what to expect from Diablo 4’s eagerly awaited expansion.

Interestingly, this post also nailed its prediction about Season 3’s theme, which revolves around the exploration of Zoltun Kulle’s vaults.

You can download a filtered list of new files added in Patch 2.0 compared to 1.2 here. The file names reveal some new features coming to the game.

New Spiritborn Class

The mysterious sixth class that Blizzard accidentally revealed through artwork which was later removed is apparently called Spiritborn. While we thought it’s a Holy Knight of sorts, it’s allegedly tied to nature based on datamining.

Spiritborn Abilities and Skills

Based on the file names, the Spiriborn class will use Vigor as resource and use Natural 1H weapons like Glaives + Shields. Some abilities are Bat Swarm, Soar (Fly/Ascend), Sky Control, Armor Split, Thorn, Soil, etc, most of them are nature-themed.
