During the 2.6 beta stage, beta testers and data miners submitted information about the forthcoming Genshin Impact upgrade. There's a lot more to come, including a new Inazuman celebration dubbed the Irodori Festival, according to reports. It's important to note, however, that any information obtained from unauthorised sources is unverified and susceptible to change until the 2.6 release date approaches.

Another Genshin Impact character to look forward to in 2.6 is Kamisato Ayaka's older brother, Ayato, a blue-haired Hydro sword user. There's already a lot of information about his playstyle available, so if you've got your primogems ready for his Genshin Impact banner, it's worth looking into the rumoured Ayato ascension materials to ensure you're ready to unleash his full potential. Here's everything we know about the Genshin Impact 2.6 update thus far.
On March 30th, 2022, the Genshin Impact 2.6 will be released. The livestream was broadcasted on March 18, 2022. 

In version 2.6, there is only one new character: Kamisato Ayato, Ayaka's brother. On March 30, the first part of Ayato's banner, Azure Excursion, will commence. There hasn't been any word on which additional characters will be joining Ayato under his banner yet.
At the same time, Venti is having a banner rerun, reviving Ballad in Goblets. Sucrose, Razor, Noelle, Barbara, Fischl, and Xiangling have all appeared in Venti's repeat banners in the past.

GENSHIN IMPACT 2.6 CHASM

The Chasm is a brand-new location that will be available in version 2.6. Although it already exists in the game - it's a strange old mine in Liyue – we'll be able to visit it for the first time in version 2.6.
The Ruin Serpent, a new boss arriving in The Chasm, was shown off during the 2.5 Livestream. The Chasm is also engulfed in crippling mud, which saps your speed and health while buffing foes that stand in it. The Lumenstone Adjuvant will be used by players to navigate the mine's perilous depths. An NPC named Jinwu may improve this item using Lumenspar and Lumenstone Ore.
