All Genshin Impact 2.6 monsters and enemies leaked so far

sportskeeda.com:

New version updates tend to include new enemies for the player to vanquish, and Genshin Impact 2.6 is no different.

There are three major new enemies that have been leaked to be a part of Genshin Impact 2.6, and their leaked names are:

There aren't any gameplay leaks of them yet, but some unofficial translations and brief descriptions feature these new foes. Their names are subject to change, but it's worth noting that some items related to these foes have also been leaked.

The above Discord screenshot features some unofficial translations of these new foes. It includes some lore and small pictures, although the official translations may change a few parts of the description.

Black Serpent Knight: Windcutter has also been leaked as a new type of the Shadowy Husk archetype (it even has an anti-shield ability like other Shadowy Husks). A leak describing its capabilities can be seen in the Tweet displayed below.

It's a rough translation, but it essentially states that this new Genshin Impact 2.6 enemy becomes stronger and faster if it hits shielded characters. Unlike the next two enemies, this foe doesn't drop any new items. Based on this rough translation, it will also utilize Anemo as its primary element.

For reference, here are the elements of the other Shadowy Husk enemies:

According to the above leak, the Ruin Serpent is a Normal Boss. The event page reveals some interesting details about it, particularly its rewards. It will drop Prithiva Topaz Ascension Materials, along with a new item that's been translated as "Runic Fang."

This boss apparently requires players to complete a World Quest known as "Surreptitious Seven-Star Seal Sundering." Unfortunately, no details were leaked about that quest in the recent Genshin Impact 2.6
