Swimming Prohibited is an achievement in Genshin Impact Challenger: Series V that can be obtained by defeating the Bathysmal Vishap Herd without allowing them to dive into the water. It’s much simpler than it sounds: you need to defeat both bosses at the same time to prevent either of them from jumping into the water.
How To Defeat Bathysmal Vishap Herd Without Allowing Them To Dive Into Water In Genshin Impact
Start by heading to Dainichi Mikoshi where you will find a hole in the ground that will lead you to the Bathysmal Vishap Herd’s cave.

The Bathysmal Vishap Herd consists of two bosses: a Hydro and an Electro Vishap with separate HP bars. When you “defeat” a Vishap, he will jump into the water and continue to attack you from a distance. The only way to prevent a Vishap from jumping into the water is to beat them both at the same time.
You need to watch out for the attacking Vishap to make sure your HP bars go down at the same time. When your HP bars get too low, try to control your off-field attacks, such as Xingqiu and Xiangling’s elemental blasts, Zhongli’s shield, and similar attacks, which might accidentally kill one of the Vishaps too early.
Once both HP bars are extremely low, one tip is to wait until the two Vishaps are side by side so you can finish off both of them at the same time. Alternatively, if your party isn’t strong enough, you can go into Co-op mode and ask a friend to take on one of the Vishaps for you. If you successfully kill both at the same time, you will get the Challenger: Series V Achievement called Swimming Prohibited.
