Abyssal God full body

Before you lies an outrageous, impossible sight!
"Gigantic" barely suffices to describe the immensity of the being you see...
The gigantic being hasn’t so much as glanced toward you. It simply lies malignantly in place...
This must be the ultimate source of the evil that lurks in the Yggdrasil Labyrinth!
Defeat the evil whose tendrils extend to the world above and win back true freedom for Armoroad!

Introductory cutscene, Etrian Odyssey III: The Drowned City


Abyssal God (昏き海淵の禍神, The Vengeful God in the Dark Ocean Abyss) is the true final boss of Etrian Odyssey III: The Drowned City. It can be fought on B25F, the final floor of the Yggdrasil Labyrinth, and is by far the hardest boss in the game, and one of the most frustrating and difficult fights in the entire series.

This creature is the final enemy of the explorers and the creator of the Deep Ones. No words can describe this colossal, tentacle ridden abomination. Its only visible part is its head, atop its body, with a huge, gaping maw.

This beast has many forms of attacks. When its mouth is closed, it uses its tentacles to defend itself, showing great skill in countering incoming attacks and restorative powers. However, once it opens its mouth and shows its true form, it attacks with unstoppable rage, using powerful elemental spells and using its huge tentacles and claws to rip apart anything that may dare to oppose its might.

Story[]

Spoiler Warning: Plot details follow. Read at your own risk.

The Abyssal God is a power-hungry god-like alien being that travels around space, seeking planets to conquer. It creates a new race on it, acting like an invasive species, destroying other predominant life forms until the race becomes the predominant one (with the races created by the Abyssal God also worshipping it as a deity). It went unstoppable for eons until another being, known as the Yggdrasil Tree, a sentient, highly powerful tree, started chasing after it in order to put an end in its rampage. In order to escape the creature landed on the earth, where it found refuge under its vast oceans and soon created a new race, the Deep Ones, in order to start a war with the planet's dominant race, humans. However, the Yggdrasil soon followed its lead, and landed on the same spot as the monster, quickly growing roots and sealing it within a labyrinth. Now sealed deep into the sea, it simply lies in wait for an opportunity to finally break free and restart the cycle of destruction.

The Abyssal God has a simplistic rotation by firing its elemental attacks in order, and its defenses and strength are dependent on the number of Tentacles still on the floor.

Once you deplete this form's health, you will transition to the next phase immediately. Any other combatants who haven't moved will skip their turn, and a new turn begins. Defeating this form will also trigger Bloody Lance from any Shogun who landed the killing blow.

The indescribable god has awakened!

The true form of the Abyssal God. It has two modes, one defensive and the other offensive. The defense mode has a lot of resistances and if struck will retaliate either with large backlash damage or by spreading ailments all across the party. It can also heal itself. After enough time passes, it changes to its offensive form, bearing deadly attacks but losing its defenses in exchange.

Since the game treats its transformations as "adding a different enemy to the fight", the Abyssal God loses all buffs, debuffs, ailments and binds when shifting forms.

Skills[]

Defense mode[]

  • Nameless Wall: When struck by a physical attack, counters with an almighty attack that deals 4x the amount of damage the Abyssal God took. If hit multiple times or by skills that lands several blows, this boss will unleash a counter for each time it has been damaged.
  • Mist Curtain: When struck by an elemental attack, counters with an almighty attack that deals 4x the amount of damage the Abyssal God took. If hit multiple times or by skills that lands several blows, this boss will unleash a counter for each time it has been damaged.
  • HD-LBind Chaotic Beckon: Moderate stab damage to the entire party. Restores some HP to the boss, proportional to the damage inflicted.
  • Spurting Fumes: When struck by any attack, counters by inflicting random status effects to the whole party. If hit multiple times or by skills that lands several blows, this boss will unleash a counter for each time it has been damaged. Can inflict petrify and a plague/poison status that deals 500 damage per turn.
  • HD-HBind Abyssal Offering: Removes all debuffs from the Abyssal God and heals for 11,475 to 11,480 HP

Trivia[]

  • The Abyssal god and the entirety of the Cyclopean Haunt have numerous references to the Cthulhu Mythos. In fact, it may be Cthulhu himself, taking into account the number of references and similarities:
    • The Cyclopean Haunt, where the Abyssal God is found, has several references to R'lyeh, where Cthulhu lies sleeping.
    • They are both worshiped by an aquatic species called the Deep Ones (Etrian | Lovecraft)
    • The B25F title, "That which can eternal lie". is a direct reference to a quote in one of H.P. Lovecraft's writings "That is not dead which can eternal lie", which refers to Cthulhu.
  • This is the first optional final boss of the series that got its own battle theme, as (Primevil used the standard boss battle music and Ur-Child used the Overlord's theme). This battle theme is called "Calling that Detestable Name".
  • This is the first boss fight in the DS series to have a fully animated background.
  • The Abyssal God is infamous for having an extremely difficult attack pattern to predict and its AI becoming more random and erratic as its HP lowers. Due to the poorly conveyed mechanics involved in the fight, and to how luck-based the battle can be, the Abyssal God stands as one of the most frustrating bosses in the series. This creates a stark contrast with the previous two superbosses in the series, Primevil and Ur-Child, who both have a more static and predictable AI, and makes the Abyssal God the first final superboss in the series to have a more dynamic fighting pattern.
  • In the second phase, once it starts randomizing, in defensive form, the skill it uses depends on whatever attacks you planned. This is known as "input reading". Input reading is also used by some Sea Quest NPCs and one Sea Quest boss.
  • Its first phase is somewhat similar to the Yggdrasil Core, which may hint at a similarity between the two.
