The Coral Defenders, also known as the Bathysmal Vishap Herd, are a Normal Boss challenge found in Dainichi Mikoshi, Enkanomiya, Inazuma. The herd consists of a particularly powerful Bolteater Bathysmal Vishap and Rimebiter Bathysmal Vishap. In order to challenge them, the player must have completed the World Quest The Subterranean Trials of Drake and Serpent in Series From Dusk to Dawn in Byakuyakoku.

These Bathysmal Vishaps were specifically modified by the Vishap Research Lab to accept grafted fragments of Orobashi's Bloodbranch Coral without adverse side effects, making them exceptionally large and powerful. This was a painstaking process, since beings of the Light Realm (such as Vishaps) naturally reject those of the Human Realm (which includes the Gods).

Cleansing Shower
Forms an orb within their mouth and launches it at the player. On hit, the orb deals 5% ATK as Cryo DMG or Electro DMG and drains 30 Energy from the active character. If the active character has less than 30 Energy, the rest of the drain is converted to HP Loss. The HP Loss is calculated as: $\begin{align} \text{HP Loss} = {} & ( 17 \% \times \text{Character Max HP} + 600 ) \\ & \times ( 1 - \frac{\text{Remaining Energy}}{30} ) \end{align}$

Spike Field
One of the vishaps plugs its tail into the ground, creating a large field, within which ice shards or Electro Energy frequently spike from the ground at random locations, dealing 60% ATK as Cryo DMG or Electro DMG. If a player is within the field, a spike will appear at the player's exact location every 2 seconds up to three times. If both vishaps are on the arena, only the Rimebiter Vishap can use the Spike Field attack. The Bolteater Vishap will not use this attack until the Rimebiter Vishap reaches critical health.

Bolteater: Summons an orb in front of it that fires three bolts in a spread after a delay. The bolts then fire themselves towards the player's position, each dealing 30% ATK as Electro DMG.

Assist
If a wall is intact, the Bolteater Vishap climbs up a wall and repeatedly launches Cleansing Shower orbs at the player. Orbs launched this way have the same Energy or HP draining effects, although with a minor homing property and a slower travel speed.

Revival
Media:Bathysmal Vishap Herd Soul Link.mp4	A visible link connects the two Vishaps. If one Vishap's HP reaches 1.2% and the other Vishap is not defeated within the next 10 seconds, the defeated Vishap will be revived with 50%/40%/30%/20% of its Max HP if revived 1/2/3/4+ time(s).

Strategy

• Dodging the Cleansing Shower orbs or having characters with high Energy Recharge is beneficial for this fight as having low Energy can prove to be fatal if the player cannot dodge their Cleansing Shower attacks.
• The pillars that the Bolteater Vishap jumps onto are Geo Constructs and can be easily destroyed using Blunt Attacks. Alternatively, try to stay far away from the Bolteater Vishap, as the orbs are harder to dodge while up close.

Adventurer Handbook, before unlocking Coral Defenders

A powerful group of Bathysmal Vishaps.
They have been specifically bred and selected by the people of Enkanomiya, which has given them their exceptional strength. Of course, no vishap would consider this some sort of debt to be repaid.
The strongest members of the herd can use different elements, which they wield as a show of their hatred.

Trivia

• Despite being a herd which would consist of numerous members, this challenge only consists of two boss enemies.
  • This also makes it the first normal boss challenge that doesn't consist of a single, unique enemy. Others include the Icewind Suite and Dual Maguu Kenki.
• The Coral Defenders were the first Normal Boss with their own battle music, No Turning Back, a remix of Beats of Water Drops.
• The Coral Defenders are the only Normal Boss that lacks an archive entry. Rather, the Bolteater Bathysmal Vishap and Rimebiter Bathysmal Vishap have their own archive entries.
• If the Coral Defenders are killed with one of them in a Critical Assist state, the vishap in that state will simply disappear with no death animation played.
• The walls in the boss fight used for skills such as Assist are considered Geo Constructs.
