A new leak claims Genshin Impact Scaramouche the Harbinger is going to be a new weekly boss in the future.
According to the leak, there is new information about the upcoming weekly boss. Insider codenamed Uncle DumbDumb claims that Scaramouche, one of the Harbingers, is going to become a weekly boss soon. It seems he is going to be added as a new boss this coming update version 3.1, which should be launching by September 2022.
The pattern fits since during version 1.1 and 2.1, archons Zhongli and Raiden Shogun respectively were introduced. It also made Childe and Signora as weekly bosses. If we were to base the numbers of every version, 3.1 could possibly mean the introduction of a new archon, the Dendro one known as the Lesser Lord Kusanali and the God of Wisdom. This would also introduce a new weekly boss, which could be Scaramouche.
This villain has been introduced for a long while now and first made an appearance in version 1.1. He was first innocent looking during a quest, but turns out he has some evil plans working behind the scenes. He also seems to have a connection to Raiden Shogun.
HoYoVerse has not made any statement to confirm this leak so take this with a grain of salt.
