Diablo 4 Season 9 is coming soon, and along with all the new content, it’s time for a new class to be the most OP spec for the season. Previous seasons, we leaned more towards Barbarian or Necromancer, and right now, it’s clearly between three very specific builds: Flay Barbarian, Poison Volley Spiritborn, and Hydra Sorcerer. However, two of those builds also take clear advantage of bugs, and bugged gear.
That leads me to just one class and spec as the most OP for Diablo 4 Season 9. It’s probably the first time that in quite a long time that I’ve been excited for a Sorcerer. When you combine their new Unique, the power of the Horadric spells, and their survivability, there’s only one choice - though I will bring up the other two for consideration.
The Hydra Sorcerer is going to be the most OP spec going into Diablo 4 Season 9
Hydra Sorcerer is hands-down the most OP and reliable spec going into Diablo 4 Season 9. Unlike Flay Barbarian and Poison Volley Spiritborn, which both take advantage of bugs, Hydra Sorcerer is simply a great build, with tons of damage, and potentially gigantic Fire Hydras. Sorcerer already has fantastic movement and survivability skills, and plenty of powerful Uniques. When you pair this with the incredible power of the Horadric spells, you’re going to have a real powerhouse.

Flay Barbarian takes advantage of a bug in the Hooves of the Mountain God Unique, and Poison Volley Spiritborn uses a bug with Double Jaguar, and both of these could get fixed within the first few weeks of the Season. Of course, we don’t know if that will happen, so that’s why I wanted to at least mention these other classes.
Flay Barbarian uses a bug to deal negative damage, to basically one-shot almost everything. Conversely, Poison Volley Spiritborn will probably still be powerful even after a bug fix. You combine their significant poison powers with new Horadric spells and the Balazan’s Maxtlatl Unique, and they suddenly become wildly tanky and deal tons of damage to boot.
However, I still prefer what Sorcerers have going into this season. Ophidian Iris is an incredible new Unique, and it shouldn’t be too hard to farm, either. It makes it so Hydra becomes a Core Skill, and will always summon a 3-headed hydra, whose attacks deal splash damage (explode on impact).

In addition, for every head above 3 that it would normally have had, it grows bigger, and deals 50-100%[x] increased damage. That is going to get out of hand incredibly fast. There’s the Enhanced Hydra skill that grants an additional head while healthy, and you can simply stack more heads via Conjuration Augments on your weapon.
This is going to do some impressive damage, and I think, overall, be more reliable, and easier to manage compared to builds that might suddenly let you down during the season, due to bugfixes. If you want to be powerful, and also have a giant fire hydra splashing down doom on your enemies, this is the build to go with in Diablo 4 Season 9 if you want the most op spec.
