Diablo 4 Season 9 drops in early July, so it鈥檚 time we talk about some of the potentially best builds. Naturally, this is based on patch notes, and general vibes going into the season about how things should fit together. These builds should all do exceptionally well this season, when you combine the right Uniques and Horadric Spell bits together. They鈥檙e all builds I鈥檓 pretty excited to play.After all, I have to find something that isn鈥檛 Minion Necromancer, thanks to all the nerfs; though frankly, the new Season 9 Unique, The Hand of Naz might see me playing Minion Necro again, because I鈥檓 personally convinced it will be good. However, if you want the best builds to try in Diablo 4 Season 9, here are my picks.Which are the best builds to try out in Diablo 4 Season 9?Hydra SorcererPoison Volley SpiritbornBlood Wave NecromancerWhirlwind BarbarianFlay BarbarianDeath Trap RogueLightning Spear SorcererOnce Diablo 4 Season 9, Sins of the Horadrim kicks off in July, the above choices are all builds I think are going to make their way towards the endgame. While I can鈥檛 promise that these will all hit the deepest levels of The Pit (since it鈥檚 supposed to be even harder now), I think they will be serviceable with the right loadout and class knowledge.1) Hydra SorcererThis particular Unique will carry Hydra Sorcerer super hard (Image via Blizzard Entertainment)It鈥檚 my belief that Hydra Sorcerer is going to be the most overpowered (and thus best) build for Diablo 4 Season 9. There are other great, powerful, top-tier builds, but I think Hydra鈥檚 going to be more reliable, and the new Unique that allows for this shouldn鈥檛 be too hard to unlock.You鈥檒l also need to do a little Masterworking and slot in the right Legendary Affixes, but I think it should be easy enough to start melting things with a giant fire hydra. When you combine this with the already great Horadric spell possibilities, and Sorcerer鈥檚 innate defensive cooldowns, it鈥檚 going to be a very fun season.2) Poison Volley SpiritbornSpiritborn aren’t going anywhere anytime soon (Image via Blizzard Entertainment)Poison Volley Spiritborn works for a few reasons, to be honest. It鈥檚 going to be one of the best builds in Diablo 4 Season 9 because Spiritborn is always a great pick. They have an amazing new Unique, which enhances Thorns and Poison damage. You combine this with a heavy poison build, and the poison spell offerings in the Horadric Spells, and suddenly, everything melts under a proverbial tidal wave of noxious, green poison.Then you have Noxious Resonance, the Key Passive, that makes our Poison even better. However, this is also overpowered because of a bug with Double Jaguar in the Spirit Hall, and there鈥檚 a chance this could be fixed. Even without that, I think it鈥檚 going to be wildly powerful.3) Blood Wave NecromancerBlood Wave continues to be the champion for Necros everywhere (Image via Blizzard Entertainment)No matter what Blizzard does to Blood Wave Necromancer, it remains one of the best builds in Diablo 4 Season 9. It鈥檚 been nerfed quite a few times now, but it鈥檚 still great! It鈥檚 also one of the easiest builds to set up. Just get Kessime鈥檚 Legacy, and you鈥檙e ready to get going.While Minion Necro is still a fantastic way to level up in D4 Season 9, I don鈥檛 know that it鈥檚 going to be easier to succeed with, compared to Blood Wave Necromancer. This one鈥檚 pretty easy, it鈥檚 powerful, and it doesn鈥檛 require the same level of intense setup.4) Whirlwind BarbarianWhilrwind Barbarians are easy and fun, what’s not to like? (Image via Blizzard Entertainment)I don鈥檛 think Whirlwind Barbarian鈥檚 going anywhere anytime soon, especially not in Diablo 4 Season 9. Flooding the screen with Dust Devils just remains an incredibly potent way to deal with enemies. Dust Devils hit hard, and it鈥檚 incredibly simple to get them moving on the screen, slaughtering enemies for you.I also like Whirlwind builds because they鈥檙e easy to play. It doesn鈥檛 鈥渞equire鈥 any Uniques, but there are several that go well with it. You will need specific Legendary Aspects, though. If you want something easy to play, that鈥檚 fairly easy to setup, and doesn鈥檛 have many downsides, this is the play.5) Flay BarbarianI think Flay still has a chance to be quite good, even if the bugs are ironed out of the new Unique (Image via Blizzard Entertainment)If Flay Barbarian doesn鈥檛 get fixed, it will easily be one of the strongest builds in Diablo 4 Season 9; even if it does, I think it still has a lot of promise. But due to a bugged interaction with Hooves of the Mountain God, they can basically use negative damage to one-shot a wide array of enemies.However, either way, this new Unique allows you to deal extra damage with Basic Skills (Flay), and also makes them cleave on top of that. It鈥檚 wildly powerful, and if you can keep building your Fury up while it drains, you can obliterate pretty much anything using the power of Flay. I have high hopes for it this season.6) Death Trap RogueSomehow, Death Trap persists as a potential build. I want it to be Flurry, but I’m not sure that it will be quite as good (Image via Blizzard Entertainment)I don鈥檛 know that the new Rogue Unique, Deathmask of Nirmitruq is going to really shake anything up. It鈥檚 in an unfortunate slot (Head), and it affects Flurry. I don鈥檛 know that it鈥檚 going to be much better than Death Trap Rogues already were going into Season 8, and again in Diablo 4 Season 9.Repeatedly casting Death Trap is incredibly satisfying, but I鈥檓 not sure if it鈥檚 going to be a game-breaker, due to a host of planned Overpower nerfs. That said, I still think this is going to be a solid pick, thanks to Preparation (Rogue ability), and gear like Banished Lord鈥檚 Talisman, Beastfall Boots, and Scoundrel鈥檚 Leathers.7) Lightning Spear SorcererLightning Spear will remain a decent, but intricate build going forward (Image via Blizzard Entertainment)While yes, I do think Hydra Sorcerer is going to be the best, that doesn鈥檛 mean it鈥檚 the only powerful Sorcerer build going into this season. I have a very good feeling about Lightning Spear. We鈥檝e talked about it many times over the lifetime of Diablo 4, and Season 9鈥檚 going to be no different.Lightning Spear isn鈥檛 as easy to use as some of the other builds, because you really have to work at mana and cooldown management, but with the right skills, and Uniques like Raiment of the Infinite, Tal Rasha鈥檚 Iridescent Loop, and Tibault鈥檚 Will, you wil have an excellent start. The downside to it is if you want it to really shine, you also need Harlequin Crest and Ring of Starless Skies, both Mythic Uniques.Check out our other Diablo 4 guides and featuresDiablo 4 Season 9 Endgame tier listDiablo 4 Season 9 leveling tier listDiablo 4 SEason 9: All Horadric Jewels
