Like the other worms (Sand Worm and Land Worm), the Abyss Worm will Swallow a party member and Regurgitate them, causing 9,000 to 9,999 damage and inflicting Delay (strong). It also uses Earthquake like Land Worms and Sand Worms, but the Abyss Worm uses Readying Quake before it does the attack (in two versions). One of them, inflicts Delay (weak).

From the start of battle Abyss Worm is immune to Sleep until he uses Earthquake. After Earthquake has been used his Sleep Resist is lowered from Immune to 80%.

Abyss Worm drops weapons with Strength +% abilities and armor with Defense +% abilities, Strength +20% and Defense +20% being fixed abilities.

Its Regurgitate attack is glitched and may end up making party members invisible until the swallowed characters have left the battleground for a summon, or the battle ends, provided a character is under the effect of Guard or Sentinel when Abyss Worm uses this ability. The glitch does not affect gameplay.


Summoning Valefor before the Abyss Worm uses Quake will negate the damage. This battle should be relatively easy if the player is well leveled up and has the Celestial Weapons.



Abyss refers to a bottomless pit, to the underworld, to the deepest ocean floor, or to hell, or more loosely to any chasm or large drop.
