How do you unlock the Bathysmal Vishaps Boss fight?

To Unlock this Boss Fight, first, you need to have Enkanomiya unlocked, which requires:

• Completing the Archon Quest Ritou Escape Plan in Chapter II: Act I - The Immovable God and the Eternal Euthymia
• Complete The Moon-Bathed Deep quest given by Tsuyuko, North of the Mouun Shrine on Watatsumi Island.
• Completing the quest The Still Water's Flow that unlocks after the previous quest to enter Enkanomiya.

After entering Enkanomiya, follow the Quests under the From Dusk to Dawn in Byakuyakoku series, and after completing The Subterranean Trials of Drake and Serpent, you'll have unlocked the Boss Fight.

Strategy

Each Vishap will have a slight resistance to its element, and both will have a slight resistance to Physical Attacks.

The Electro Vishap will climb one of the walls to shoot at you from a distance; you can destroy these walls to completely stop him from making this attack, so consider bringing a Claymore character or your preferred method of breaking rocks; you can also destroy them while he is on the wall to make it fall to the floor.

After one of them reaches low health, it will start swimming around the arena, shooting its element at you, so be mindful of that.

Weak Point

Both Vishaps receive increased damage when hit on the head.

If you break one of the walls while the Electro Vishap is on it, it will fall to the ground and remain stunned for a short instant.

Achievements

Swimming Prohibited

Hard Landing

Bring a climbing Bathysmal Vishap down.

Wait until the Electro Vishap climbs one of the walls and then destroy it.
