The ancient tome recovered by Captain Radlia of the Talons tells of a floating refuge─an island created by Mhachi sorcerers to provide safe haven from calamitous floodwaters. With the disaster that befell the Void Ark, however, the island's intended residents never arrived. Cait Sith is convinced that Diabolos has instead claimed this refuge as his own, transforming what was to be a bastion of hope into a voidsent nest of shadowy nightmare. And it is into this fiendish lair that you must delve.
The Lady Radlia stands ready to bear you across the skies. Assault the island, reclaim the Nullstone, and cast your demonic foes into oblivion!

Bosses

Deathgaze Hollow

There are no walls on the left and right side of the ship so be careful not to fall off. Throughout the fight, the boss moves between these sides to attack you and make you fly off to your death.

First Half

The boss opens up with Void Death. This is a large red-black, circle area of effect (AoE) at the center that pulls you in a couple times. You must keep running away from it or anyone caught in it dies.

Next, it casts Void Aero II and marks three players with green spread markers. Go to a place away from everyone to place the tornado. Anyone walking into the tornado will get hurt by Biting Wind, which gives you small damage and the Windburn debuff. Windburn can be removed with Esuna.

When the boss casts Void Blizzard II, avoid the fan AoE by going to either side or on the safe spots in between. If you don’t, you receive a large amount of damage from Void Blizzard III and get the Frostbite debuff. Frostbite can be removed with Esuna

Throughout the fight, the boss casts Doomsay which randomly gives Doom to one to two players. Healers must use Esuna to remove them or they will die when the countdown ends.

If the boss casts Void Aero III, immediately get close to either purple walls on the top and bottom of the ship. A green circular wind will appear in the center that causes proximity-based damage and knockback, so make sure you aren’t too close to it or you may die from damage. If you aren’t against a wall, you may fly off to your death.
NOTE: The wind makes you fly in a straight line from the center, so you must be perpendicular to the purple wall to fly into it. See the image on the left to see the direction of where the wind blows.

When Void Blizzard IV is cast, stand directly opposite of either proximity markers and take the damage. Ice blocks are dropped where the marker is located, and the boss immediately casts Void Aero IV. If you try to stand where you take the least amount of damage from the proximity marker, you might not have enough time to get to the ice block. If you stand where the opposite side of the ice block was located, you will fly to the block when Void Aero IV is cast, blocking you from falling off. Anyone who didn’t fly into the block will fall to their deaths.
NOTE: You can also use Surecast or Arm’s Length to stop you from flying off, but make sure to time it right because you only have a five or six-second duration.

Second Half

In the latter half, everything repeats with some differences.

The boss casts Doomsay more often, and only one proximity marker is placed on the floor when the boss casts Void Blizzard IV.

After Void Aero III is cast, the boss immediately flies right beside a purple wall and casts Bolt of Darkness. The boss shoots out a large, column AoE across the ship while the green wind on the center from Void Aero III blows people away. Bolt of Darkness gives you Bleed, which can be removed with Esuna. If you can, go to the purple wall where the boss isn’t next to, to avoid Bolt of Darkness.

Make sure to kill the two Void Sprites that spawn randomly. Avoid their cone AoE when they cast Dark II.

Since the beginning of the fight, the boss places random gray squares on the ship’s floor. In this half, the boss finally uses Void Death IV, which makes the squares pulse. Anyone standing on them when the cast is done, dies.

*Italicized words are names of casts

Ferdiad Hollow

Throughout the fight, Ferdiad will mark 3 players with red markers and throw Abyssal Scythes on them. The scythes will stay on the ground, dealing damage to anyone close to them.

Also throughout the fight, Ferdiad will summon Atmos, and tether to one or two of them and cast Wormhole.
Wormhole: Shoots a ball in a straight line into the tethered Atmos. The tethered ones disappear after the cast, transferring their balls to a same-colored Atmos.
- Yellow Atmos transfers ball to another yellow Atmos, and blue Atmos transfers ball to another blue Atmos; the ball color will not change.
- The yellow ball explodes in a room-wide donut-AoE (safe zone near it), and the blue ball explodes in a big AoE (no safe zone).

Jester's Reap: Big cone AoE in front of the boss.
Jongleur's X: Tankbuster.
Blackblot: Marks a target. Others should stack on the targeted player to share damage.
Blackfire: AoEs will cover the arena. Those become gradually bigger as the cast progresses.

Debilitator: Reduces all players' weakness to fire or water, and spawns various puddles on the floor. Stepping on a puddle changes its element (blue = water, red = fire). The boss will cast Flameflow after a while.
- Players should change puddles' element to the one contrary to their weakness - if you have fire weakness, change puddles to blue (water).
Flameflow: Deals damage to all players. Damage can be reduced by avoiding puddles of the same element of the group weakness.

At around 60% health, the boss will go to the middle of the room and become untargetable, spawning Atmos around him which mobs will shot from them.
- Anyone in front of the Atmos will take damage and a stack of vulnerability.
From time to time, the boss will cover a half of the arena with a long-cast AoE. It will kill any players standing on that side when the cast finishes.
The adds will either cast:
- Lucky Pierrot: Atmos will spawn around the edges of the room, and adds will dash to them, dealing damage to anyone on the way. The adds will reappear from the Atmos in the center, dealing damage to players nearby.
- Icafall: Small AoEs.
After the adds are killed, the boss will deal damage to all players.

Scathach

When wings(?) get really big be in front or behind THEM, boss direction doesn't matter
When she ports she will do large aoe a few seconds later
When message about shadows on the ground pops up, stop all movement, otherwise little arms grab you and do a good amount of damage
Occasionally she will turn toward party and do line aoe, sidestep it
Move adds away and kill, if they get too close they tether and buff her
Shadow Limb (giant hands) link to a player when spawned and will be pulled toward that player, killing the player if they reach the player. The tethered player can face the Shadow Limb to make it stand still. The Limbs must be DPSed, and can switch tethers to a different player.
At 50%, Scathach will enter a cocoon and spawn adds, including a Chimera with the typical Chimera moveset.
These adds must be killed, or she will wipe upon emerging from the cocoon.

Diabolos

Phase 1: Diabolos

Nightmare - Look away from Diabolos, inflicts sleep
Ultimate Terror - Donut AoE - Stand close or very far away
Ruinous Omen - Raidwide AoE
Night Terror - Stack marker on random player, stack to share damage

Phase 3: Diabolos Hollow

Diabolos starts with 100% crit and a large shield. Watch main tank's hp until shield breaks. Hollow Camisado will one-shot low geared tanks without cooldowns. Kill Deathgates and assign people to do Diabolic Gate (Usually Alliance A for Adds).
