Genshin Impact 6.6 Hexerei Buffs Leak: What We Know

I’ve been a Genshin Impact player since the very first day I logged into Mondstadt’s wind-swept hills, and let me tell you—this 2026 leak about Version 6.6’s Hexerei buffs has me screaming into my teacup of dandelion wine. After six years of watching my favorite old Mondstadt characters get left in the dust by flashy new Sumeru, Fontaine, and Natlan units, HoYoverse is finally circling back to the region that started it all, and it’s about time.

First, let’s recap the lead-up, because this isn’t just a random buff drop. Version 6.4’s flagship event was a full-on nostalgia trip, making me cry when I replayed the Traveler’s first meeting with Venti and the first time I fought Stormterror. Then Version 6.5 is dropping Dornman Port, a brand new Mondstadt map expansion that’s been teased for literal years—like, I still have a screenshot of the port’s outline from the 2022 Liyue Harbor update, I swear. But Version 6.6? That’s the capstone. The big one. The one that’s going to make me dust off my old character builds and delete the Fontaine units I’ve been maining for months.

For those who don’t remember, the Hexerei system launched back in Version 6.2 with Durin, right? It’s basically HoYoverse’s way of saying “oops, we made these characters too weak for the current meta, let’s fix that.” The first round of buffs hit Razor, Fischl, Sucrose, Mona, Venti, Klee, and Albedo—and let me tell you, my Razor went from being a bench warmer to carrying me through the Spiral Abyss. The community lost its mind, begging for the rest of the iconic Mondstadt crew to get the same treatment. And now, a reliable leaker named Writer-X—who’s been spot-on since Columbina’s debut—says Version 6.6 is bringing the next set of buffs, and the list is chef’s kiss: Amber, Kaeya, Lisa, Jean, Noelle, Mika, and Eula.

Let’s break down why each of these is a big deal, starting with the ones I’ve been begging for. Amber, for example—she’s the first character you get, and for years she’s been the butt of every Genshin joke. “Amber is useless” is a meme older than the game itself. If she gets a Hexerei buff that makes her Pyro damage actually competitive? I’m maining her. No questions asked. Kaeya? My first 4-star, the guy who gave me the Cryo vision that got me through the first Dragonspine. He’s been stuck as a sub-DPS for ages; a buff could turn him into a full-on hypercarry. Lisa? The librarian with the best voice line in the game (“I am Lisa, the librarian. I hope you don’t mind if I take a peek at your soul”)—her Electro damage has been so outclassed by Fontaine’s Electro units that I haven’t used her in a year. A buff? I’m pulling for her constellations immediately.

Then there’s the big ones: Jean, Mika, and Eula. Jean is the Acting Grand Master, and for years she’s been stuck as a mediocre healer with a burst that’s hard to use. If her Hexerei buff turns her into a top-tier support? That’s a game-changer. Mika is a newer unit, but he’s been underpowered since his release—his buffs are too weak, his healing is too slow. And Eula? Oh, Eula. My girl. The Physical hypercarry who’s been left in the dust since Version 3.0, when HoYoverse decided Elemental Reactions are the only way to play. Her whole playstyle is built for a version of the game that doesn’t exist anymore. If the Hexerei buffs fix that? I’m crying. Literally. I have a whole Eula cosplay that I’ve only worn once because she’s so weak.

And let’s not forget the two new Hexerei characters coming in Version 6.6: Nicole and Lohen. Nicole is rumored to be a 5-Star Pyro support for Varka, with a shield and attack buffs that scale with the number of Hexerei members on your team. That means if you run a team with Nicole, Jean, and Mika? They’re all getting buffed. Lohen is rumored to be a 5-Star Cryo hypercarry and the next Standard Banner unit. Both of them are part of the Hexerei, so they’ll have synergy with the buffed characters—potentially bringing the total Hexerei cast to 18. That’s a whole new team archetype.

There’s one bummer, though: Diluc and Bennett are left out of the buffs. Diluc is the original Pyro hypercarry, and Bennett is the best support in the game. It’s weird that they’re not getting buffed, but it does mean Varka will probably be locked into using Nicole as his main Pyro support. On the flip side, the buffs could be the start of a Physical damage revival. Sandrone is rumored to be a Superconduct character coming in Version 6.7, so Eula’s buffs could go either way: either make her a better Physical hypercarry, or nudge her into a more modern playstyle that synergizes with Elemental Reactions.

The best part? The beta for Version 6.6 starts on April 8, 2026. That means we’ll know all the exact buff details in just a few weeks. I’ve already cleared my schedule for the beta stream, and I’m already planning my new teams. I’m going to run a Hexerei team with Amber, Kaeya, Lisa, and Nicole. I’m going to run a Physical team with Eula, Mika, Lohen, and Sandrone. I’m going to make HoYoverse regret ever making these characters weak.

If this leak is true? Version 6.6 is going to be the best update in Genshin Impact history. It’s a love letter to the region that started it all, and it’s a chance for old players like me to reconnect with the characters we fell in love with six years ago. I’m ready. I’ve got my dandelion wine, my old character builds, and my Eula cosplay. Bring on the buffs.
