With the release of the Genshin Impact 2.5 Update, many new features have appeared in the game. While new character banners, events, and new weekly bosses appear, these hidden achievements aren't listed publicly, only revealing when you earn them. Completing these is very important if you want to earn Primogems and level up your Adventurer Rank. MMOWTS will introduce new hidden achievements.
After completing all achievements in specific categories, you can also unlock special name cards to use in your profile. Hidden achievements are hard to get because you can't find them anywhere and only appear when you meet the requirements to get them. But we've collected the hidden achievements added in the 2.5 update:
* Impeccable Judgement - "Only shoot down your real opponent..."
* Basically Harmless - "Defeat a Specter that has not accumulated any Fury."
* Hard Landing - "Bring a climbing Bathysmal Vishap down."
* Beware of Angry Dog - "Defeat a roaring Rifthound."
* Inugami's End - "Destroy two Rifthound Skulls within a short time."
Rewards
Once you get the achievement, you can get 5 Primogems as a reward. All of the new hidden achievements can be easily earned as long as you are aware of their existence. The list of available hidden achievements will continue to grow as achievements are continuously updated. At that time, MMOWTS will continue to be updated.
MMOWTS will not only offer some gameplay guides but also cheap Genshin Impact Accounts with any characters you like, which includes Yae Miko, Raiden Shogun, and more.
