It is the hardest instance in patch 2.2 of A Realm Reborn, and a spiritual successor to the Rivenroad trial from Legacy. The raid was first completed by the Free Company Order of the Blue Garter on Excalibur server on April 13, 2014.

Objectives

• Defeat Nael Deus Darnus.

Strategy

Nael Deus Darnus

MTQCapture Video Guide

An extremely infamous and difficult fight, Nael Deus Darnus will test the party's ability to coordinate as a group to a high degree. A single person stepping slightly out-of-place will often result in the death of the entire party.

This boss has four phases, with the second being a transitory invulnerability phase.

Phase 1: 100%-65%

---

The arena will be surrounded with a wall that causes instant-death to any that touch it for the entirety of the fight. Be careful when running near the edge.

Phase 1 Abilities

Name	Description
Ravensclaw	A cleave attack. Cast between attacks and is not tied to attack rotation.
Ravensbeak	A powerful casted tankbuster. The player is then debuffed with Raven Blight for 12 seconds. When Raven Blight expires, the player explodes in an AoE— dealing high damage to themselves and anyone nearby. Is cast every 45-50 seconds and is not explicitly tied to attack rotation.
Stardust	A random player that is not the main enmity target will get a yellow or purple marker. After a few seconds, the marker will disappear and a comet will drop on that location. Comets do proximity damage based on their landing location. Targeted players have a few seconds to move before the marker disappears, then another few seconds to move from the drop point. If two comets are in close proximity to each other (~5 yalms), one will explode and wipe the party.
Iron Chariot	Nael jumps to the farthest player and begins casting a Static circle AoE around themselves that deals knockback. Always combined with Thermionic Beam.
Thermionic Beam	A Stack marker indicated by a red marker on a player during Iron Chariot.
Raven Dive	Nael jumps onto the highest enmity target after Thermionic Beam, dealing minor damage in an AoE.
Lunar Dynamo	A Static donut AoE centered on Nael. Damage dealt to players by this attack with heal the boss.
Meteor Stream	Four random players are marked with purple spread circle arrows. This attack may happen twice in rapid succession.
Dalamud Dive	A much stronger version of Raven Dive that will kill non-tanks. Always follows a Meteor Stream.

The key to surviving the first phase will be correctly placing the Stardust comets around the arena, as putting two comets too close to each other will instantly wipe the party.

As Nael will repeatedly summon more comets as the fight progresses, Phase 1 has a soft DPS check to reach phase 2 before space runs out.

A faster Phase 1 clear will result in an easier start to Phase 2.

Phase 1 Rotation

Attack	Strategy
Stardust	Players should be prepared to run the comet to a safe spot away from the party and other comets.
Ravensbeak	The tank should use a mitigation and preferably tank swap to avoid putting the rest of the party at risk of exploding once Raven Blight expires.
Raven Dive + Iron Chariot	The party should move out of the AoE and towards whichever player is marked for Thermionic Beam.
Thermionic Beam	All players except the tank debuffed with Raven Blight should stack.
Raven Dive
Stardust	With every cast, the safe spots for comets decreases. Have a plan for where you would want to run if you're marked before the cast happens.
Lunar Dynamo	Melee players can stack on the boss while ranged can be at max range. Players will need to prepare to spread out the instance this cast finishes.
Meteor Stream	Spread out to avoid overlapping AoEs.
Dalamud Dive	The tank should avoid standing near other players, as this AoE will kill non-tanks.
Ravensbeak	Mitigate and tank swap.
Stardust	Move the comet to a safe spot.
Meteor Stream x2	Healers will need to be on their toes, as a lot of AoE damage will happen in rapid succession.
Dalamud Dive	Tanks should not stand near others.
Loop Repeat

Note: While this is accurate to the overall rotation for the first loop, the longer Phase 1 continues, the more offset Ravensbeak casts will be in relation to the other attacks. These mechanics will repeat until the boss is reduced to 65% HP.

Recommended spots to place Stardust comets. The "tails" aligning the edges of the floor's glyph can be used as markers.

Phase 2 - 65%

---

Nael Deus Darnus will fly into the center of the arena and become invulnerable. Three random players will be targeted with Green Comet markers that, like Stardust, must be dropped away from other comets on the field.

These Green Comets will transform into three enemies, each with a different color and set of abilities.

Phase 2 Enemies

Appearance	Name	Attacks	Description
	Red Dalamud Spawn	Earthen Heart	Targets a random player with a Static circle AoE. This attack leaves a puddle on the ground that inflicts a ~1000 Burns damage-over-time debuff.
		Heavy Strike	Three 270 degree Static cone AoEs in a wave pattern that deals high damage.
	Blue Dalamud Spawn	Magnetism	Pulls all players, comets, and other Dalamud Spawns towards this enemy in a ~10 yalm radius.
		Earthshock	An interruptible attack that inflicts Paralysis on all players for 20 seconds.
	Green Dalamud Spawn	Demolish	High unavoidable party-wide damage.
		Stone skull	A tankbuster.
		Boulder Clap	A cleave attack.

These Dalamud Spawn will absorb any nearby comets, growing in size and gaining a buff depending on the color of the comet absorbed. Red comets grant Damage Up while yellow comets grant Haste.

If a Dalamud Spawn absorbs a total of four comets, or absorbs another nearby Dalamud Spawn, it will grow enormous and become functionally invincible, wiping the party.

However, if any comets are remaining when Phase 2 ends, they will explode and wipe the party.

To succeed, players will need to not only keep all Dalamud Spawn separated from each other, but also bring them close enough to absorb comets without over-feeding them until all comets are removed.

As there are three golems and only two tanks, one Dalamud Spawn will likely need to be tanked by a DPS or Healer. The Green Dalamud Spawn must be held by a tank, however, as its abilities will quickly kill a DPS or healer.

Thirty seconds after spawning, all living Dalamud Spawn will exchange colors randomly with each other. Dead Dalamud Spawn can not exchange colors, thus removing that color from play.

After sixty seconds have passed, six more Stardust comets will drop targeting random players, followed by another three Green Comets. Players will then have another minute to repeat the cleaning process.

There are two common strategies to placing the six Stardust comets:

The first strategy is simply to have all players spread out equally around the edges of the arena, pre-positioning to different meteor placement spots. This requires individual coordination from all players to take note of when they themselves or their neighbors get targeted. Players can get targeted multiple times in a row, so all players must have multiple potential spots to run to planned ahead of time.

The second strategy, commonly referred to as "Mario Kart", is to have all players stack together on the edge of the arena prior to the Stardust casts. Once the first marker appears, all players run together in the same direction circling the arena until all six comets are dropped. This creates a simpler Stardust phase but a slightly harder Dalamud Spawn phase as all comets will be grouped closely on one half of the arena. Additionally, if any player is too far in front or behind of the stack when running, they risk mis-aligning the comets and wiping the party.

Once another sixty seconds has passed, Nael will begin casting Megaflare.

Megaflare deals high unavoidable party-wide damage and indicates the beginning of Phase 3. If any Dalamud Spawn are still alive at this point, they will merge and wipe the raid. Any remaining comets will be detonated and result in the same.

Phase 3: 65%-47%

---

The arena transforms, the glyph on the floor disappearing and being replaced with a scorched red floor. Nael gains a completely new set of attacks for this phase.

Nael loses her frontal cleave attack from this phase onward, allowing DPS and Healers to stack in front of the boss if needed.

Phase 3 Abilities

Name	Description
Heavensfall	An unmarked epicentral knockback created from a tower dropping on the center of the arena. This tower will repeatedly create Static cone AoEs that deal high damage and inflict Paralysis. The AoE patterns created by the tower get more complex and difficult to dodge with every cast. The first will be two 90-degree cones, the second alternating cones, and finally the third will be a rotating wave pattern.
Supernova	Two random players will be targeted and hit by a black hole, hitting for ~450 damage and creating a landmine. Players who trigger these landmines are dealt ~4500 damage and inflicted with the Heavy for 5 seconds.
Bahamut's Claw	Hits the main enmity target twice in a row for medium damage.
Binding Coil	Inflicts a random player with Garrote Twist, a 60 second debuff that repeatedly inflicts stacks of Garrote. If Garrote reaches 9 stacks, the player will instantly die. Garrote Twist can only be removed by absorbing one of the three white circles dropped by the Ghost of Meracydia on death.
Ghost of Meracydia	A dragon enemy that casts tankbusters, fire puddles, and Binding Chain, which will slowly add stacks of Garrote to random players until this enemy is killed. On death, will cast a massive Static circle AoE called Neurolink Burst that, if not escaped, inflicts 4 stacks of Garrote. On death, will drop three single-use white circles that are absorbed when ran on top of. These clear Garrote Twist and all stacks of Garrote.

This phase the shortest and the simplest, but can still catch players off guard. The most dangerous attack is Heavensfall, which can instantly kill unaware players who are too close or too far from the center.

Players will need to remain vigilant for Garrote Twist as, if left uncleansed for too long or kept into Phase 4, it will result in the debuffed player's death.

Phase 3 Rotation

Attack	Strategy
Heavensfall	Avoid standing directly under the tower in the center, but standing too far will cause the knockback to push players into the death-wall.
Supernova x2	(Not cast for the first Heavensfall) — Players will have to avoid the landmines and the tower's AoEs.
Bahamut's Claw	Healers be ready to keep the tank topped up.
Binding Coil
Ghost of Meracydia	The off-tank should pick up this enemy and all DPS focus it down as fast as possible. Leave any white circles on the ground for people with Garrote Twist.
Bahamut's Claw
Binding Coil	The player targeted by this should try to run and grab one of the white circles before the next Heavensfall cast.
Loop Repeat

Once Nael is brought to 47% health, she will begin her final phase indicated by casting Bahamut's Favor.

Phase 4: 47%-0%

---

Once Nael reaches 47%, she will summon three dragons outside of the arena, as well as combine her attacks from Phase 1 with a series of new attacks.

Phase 4 Abilities

Name	Description
Bahamut's Favor	Nael buffs themselves with a stack of Damage Up permanently. Always followed immediately by Bahamut's Claw.
Bahamut's Claw	Attacks the main enmity target with high damage five times in rapid succession. The unmitigated damage of this attack can kill a tank twice-over.
Ice Dragon	Hits players with Iceballs in order of the party list, inflicting them with Frostbitten. Frostbitten players are instantly killed by the next Iceball. Frostbitten is removed by being hit with a Fireball.
Fire Dragon	A random player is marked with a tether, then shot with a Fireball AoE. All players in the AoE are inflicted with Scorched— making the next Fireball kill instantly. Scorched is removed by being hit with an Iceball.
Lightning Dragon	One player is debuffed with Thunderstruck for five seconds. When this debuff expires, the inflicted will burst in a small AoE, damaging other nearby players and inflicting them with a 20 second Paralysis.
Cauterize	Two players are marked with a dark-green circle one after the other. When these markers disappear, the dragons on the outside of the arena will attack those locations with giant Line AoE charges that deal heavy damage and knockback. The location the dragons will charge is where the targeted player is standing when the marker disappears. It is possible for the targeted players to dodge the attack by using Sprint to run the instant the marker disappears.

The three potential dragon positions and where players marked by Cauterize should stand.

The three dragons will attack separately from Nael but still follow a strict timing. The Fire Dragon and Lightning Dragon always attack at the same time. The Ice Dragon fires between three to four Iceballs between every Fireball.

The biggest hurdle will be handling the dragon's debuffs between Nael's onslaught of attacks, as well as Cauterize— all of which can quickly result in a party wipe.

The three dragons will appear in one of three random patterns, only changing after a Cauterize. As these patterns determine where dragons will charge from for Cauterize, it is important to take note of which pattern the dragons are in at the start of the phase.

Players will need to take note of who is marked first and second, and which exact position those players need to run to based on the dragon's placement pattern, all in order to prevent the dragons from charging through the center of the arena and knocking the party into the death-wall.

Phase 4 Rotation

Attack	Strategy
Bahamut's Favor	Will follow up immediately with a tankbuster. Tanks and/or healers will need to be prepared.
Bahamut's Claw	Tanks will either need to use several large mitigations to survive this, an invulnerability, or a will-timed tank swap between swings.
Raven Dive	Will jump on the farthest player. Players may want to stay near the boss to prevent Nael from moving too far.
Lunar Dynamo	A donut AoE where one player will be inflicted with Thunderstruck. The debuffed player should move to the opposite side of the boss while the party stacks safely together away and from them.
Iron Chariot	Start spreading out in preparation for the next attack.
Supernova x3	Players should spread out a short distance away from the boss to leave space clear for everyone to stack for the follow-up Thermionic Beam.
Thermionic Beam	Once the third Supernova is cast, all players should immediately run together to stack.
Bahamut's Claw	Once again, tanks should use heavy mitigations, an invulnerability, or a well-timed tank swap.
Cauterize	The first marked player should run to their designated point based on the dragon placement while the rest of the group stays in the center. The second player moves to their point once marked.
Meteor Stream / Lunar Dynamo	On the first rotation, players will need to spread out for Meteor Stream. On the second rotation, Nael will instead require players to stack for Lunar Dynamo.
Loop Repeat

The boss will cycle through these attacks with the dragons firing attacks and debuffs in a set order until around 13 minutes where the boss enrages. When the boss enrages, players will have to kill the boss before the Megaflare cast finishes, or the party will be wiped.

Solo Unsync

This duty may be soloed unsynced by most jobs at around level 90, and possibly earlier for DPS jobs. There are two DPS checks that must be fulfilled:

• Phase 2: Golems must be killed before they are able to merge. There is a small window of opportunity after they spawn where they are idle and a player must be able to oneshot them. If they are allowed to merge, the resulting golem will be almost invincible and a reset via the death wall will be needed.
• Phase 3: Nael Deus Darnus must be burned down as fast as possible before the dragons are able to apply two stacks of ice or fire, which is instant death.

Blue mage solo setup

A Blue Mage can clear the duty solo unsynced at level 70 within phase 2, using the following setup:

• Full set of Augmented Scaevan Armor and Augmented Scaevan Accessories.
• Prior to entering the duty, use Aetheric Mimicry to mimic a DPS.
• Once inside the duty, cast Basic Instinct.
• Damage the boss until about 66% HP - get as low as possible without hitting the phase change threshold of 65%.
• After the boss's HP has been lowered, use the following combo of spells: Tingle, Moon Flute, Whistle, Off-guard, and finally Final Sting. The boss should instantly die from Final Sting's damage, skipping phases 3 and 4.

Dialogue

Cutscene 1

Start of cutscene.

Alisaie

That...that surely cannot be Dalamud!? How— Where are we!?

If the player is a Legacy character

Nael Deus Darnus

Your companion knows this place well. For it was here that she/he slew Nael van Darnus.

Otherwise

Nael Deus Darnus

The final resting place of Nael van Darnus.

Nael Deus Darnus

This is a grave for the undeserving.

And for the crime of trespassing upon my god's sanctuary, this place shall serve as your grave too!

Alisaie

No!

Nael Deus Darnus

In the hour of his failure, Nael van Darnus felt the currents of aether begin to bear away his essence. But before oblivion could claim the last of him, a divine will reached out...and I was born.

Then did the words of my god resound in mine ears...

“Bring unto mine enemies crushing defeat, that they might know despair without end! And claim thee thus the victory which thou wert once denied!”

Alisaie

...'Twould seem that little remained of Nael's essence when Bahamut plucked him from the brink of oblivion. And the result was this strange...simulacrum. Nevertheless, her aura bespeaks great power. She channels the rage of the elder primal himself...

Nael Deus Darnus

Lord Bahamut! Thy wish is my command! None shall 'scape Thine unquenchable fury!

Come, ye dull, unthinking beasts...bare your teeth!

They will avail you naught in the calamity to come!

End of cutscene.

Cutscene 2

Start of cutscene.

Alisaie

Poor creature. Would that you had never been born.

You had surrendered your physical form, and collapsed into aether... But Bahamut denied you death, and imprisoned what little was left of you in an aetherial shell resembling...what, I wonder? Images from your memory, perhaps?

But that shell is now broken. And your primal deity seems disinclined to sustain your existence.

Nael Deus Darnus

My “primal deity”? I kneel to no eikon! What need have I to beg the favor of such filth!?

Nael Van Darnus

I am Nael van Darnus! Legatus of the VIIth Legion...

No... A moment... My thoughts are clouded...and this body is not mine own. Could it be that you spoke the truth? Was I ensorcelled by the lesser moon's ancient prisoner? ...That will not happen again.

Alisaie

You speak as if Bahamut no longer controlled you! But that's impossible! Once a primal ensnares a mind, it cannot be freed!

Unless... Unless Bahamut simply relinquished his claim. What need has he of a broken spirit bound for the aetherial realm?

Nael Van Darnus

Ohhh...that I should fall prey to the very influence I sought to purge from the land. The irony is galling.

But do not assume that all of my actions were chosen for me. It was my will that the Meteor project be resurrected—mine and none other.

Yet it seems that my grand designs were destined to fail. Even the ungentle release of death was denied me...

Alisaie

Nael, please. You must tell us more of the Calamity. I must know the truth of what has befallen the world...and what has become of my grandfather, Archon Louisoix.

Nael Van Darnus

You are Louisoix's grandchild? Ah, the fates are generous with their cruelty.

Continue on, if you would have your answers—they await you at the terminus of your path. But know that this path leads only to despair. The light of truth was ever harsh and unforgiving...

Alisaie

Why do you say this? Grandfather will be freed once we put a stop to Bahamut's restoration, will he not? What are you not telling us!?

Nael Van Darnus

Steel yourself, child. Only unbending resolve and merciless strength can conquer what lies ahead.

The weak can do naught but weep under the pall of their own misery. As did the frail child I once was...

???

Silence, chattering raven. Your wretched wings are broken, and you shall soar no more.

Nael Van Darnus

My crimson moon... Your brilliance sears mine eyes...

Alisaie

I recognize that voice, Forename. But never would he say such words...

Come, let us finish what we came to do. All will be put aright when the final hulk lies dormant. Grandfather will be himself again...I'm sure of it.

End of cutscene.

Cutscene 3

Start of cutscene.

Alisaie

Bahamut regenerates more swiftly than I had anticipated. Let us hope that disabling this coil will serve to slow the process.

The display seems...different, but the controls appear to mimic the mechanism we found in the La Noscean hulk. It shouldn't pose a problem.

...Forename, forgive me. The moment I beheld Nael's transformation, hope wilted in my heart. I did not believe you could stand against the manifestation of Bahamut's power.

For all your fabled strength and skill, I felt certain then that I was going to lose you—just as I lost my grandfather. Even he, a man for whom naught seemed impossible, was humbled before Bahamut's might.

And yet, look how far we have come.

'Tis incredible the feats of which we are capable—our boundless potential.

'Twas this capacity for greatness, I believe, that Grandfather so dearly wished to protect. With all that has occurred, I have come to understand that much at least.

'Tis done. Shall we make our way back to the surface and gather our thoughts? We have seen much that will benefit from Urianger's learned perspective.

Grandfather!? It is you! Then...why?

Louisoix

Abandon this quest, Alisaie. I will not countenance further sabotage of the coils.

Alisaie

“Sabotage”? But...but we must disable the coils if we are to prevent Bahamut's revival!

Louisoix

Your defiance seals your fate.

Alisaie

No... No, you are not who I thought you were... My grandfather would never...

Louisoix

Foolish girl.

How could the White Raven allow herself to be bested by such sniveling opponents?

Listen well. We all exist at the pleasure of one divine will.

And the word of Lord Bahamut is absolute!

Scurry back into your holes, vermin. You have been granted this one reprieve. But should you be so foolish as to crawl into my lord's domain again, I will crush the life from you myself.

Alisaie

That light in Grandfather's eyes... He has suffered the same fate as Nael.

My grandsire is no more. That was naught but a phantom that profanes his noble memory...

This mockery must be expunged! I will not rest until I free Grandfather's soul from Bahamut's tyranny.

Do you hear me, Bahamut? Your time is at an end! Eorzea—and my family—will be avenged! is at an end! Eorzea─and my family─will be avenged!

End of cutscene.
