2 Gharj

Gharj is the second encounter in the Eternity Vault.

In this encounter, the group must regularly switch platforms as the current one will disappear in the lava.

His main mechanic is Frenzy:

During Frenzy, which is announced as “Gharj is entering a Frenzy”, the platform the group is currently on will shake; at the same time, a new platform will appear. When Frenzy ends, the old platform will disappear; the group must therefore move to the new platform in time. Standing in Lava should be avoided since it deals damage. When the tank is on the new platform, Gharj will Attack and Damage Type: Tech, Kinetic (AoE)
View on swtor.jedipedia.net Leap to them, stunning them for 2 seconds. Frenzy happens when the boss’ health falls below 95%, 70%, 50%, 30% and 10%, respectively. Below 50%, adds will spawn as well. They can be killed easily; the priority however is to get to the new platform.

Another ability is Attack and Damage Type: Melee, Kinetic (AoE)

3 The Ancient Pylons

The Ancient Pylons are the puzzle boss of the Eternity Vault. The encounter features two pylons, one in the North, one in the South. In order to complete this encounter, the group must split up and solve both pylons simultaneously.

A pylon is solved if the symbols on the central wheel of the pylon match the ones on the sides. This can be achieved by clicking on the Rotate Right / Left Consoles which will rotate the wheel. Once the symbol on the central wheel matches the one on the sides, the Confirmation Console must be clicked. As soon as the Confirmations Consoles on both pylons are clicked, the next wheel can be rotated. This happens until the puzzle is solved.

During the encounter, waves of adds spawn. They can be killed easily, however there are two mechanics to keep in mind.

Rakata Eternal Guardians cast a Incoming damage reflected.
Duration: 10 seconds
View on swtor.jedipedia.net Force Barrier on themselves, reflecting all incoming damage.

Rakata Eternal Wardens stun their targets.

The puzzle must be completed in under 3:55 minutes, else the pylons will reset. Some time before the reset, waves of Acklays will spawn dealing considerable damage. The pylon solver below can tell the fastest way to solve the puzzle.

Hard Mode

The only change in Hard Mode is that everyone who clicks the Rotate Left / Left Consoles will receive the debuff You cannot interact with the Ancient Pylon.
Duration: 30 seconds
View on swtor.jedipedia.net Pylon Ward , preventing them from interacting with those consoles for 30 seconds. Therefore, the group on each pylon must rotate with clicking. At least two members per group are required for this rotation, it is however smoother with three.

4 The Infernal Council

The Infernal Council is the fourth encounter in the Eternity Vault and is a series of duels.

Before the fight, every player must choose an opponent. In general, tanks should take Lords, DPS Marauders and Healers Assassins. The encounter can be started by clicking on the console in the room. Do not click on that console until everyone is assigned to a boss.

When a player attacks a boss, the boss will lock onto them, indicated by a green beam.

It is important that the battles must be 1 vs. 1 battles. Other players may not intervene in any battle except their own. Therefore, no healing or guarding others, no raid buffs should be used, etc. After a player killed their own boss, they can do one single attack which then applies the debuff You have attempted to assist someone else in their duel of fates. As a result you have incurred the penalty of destiny. Outgoing damage and healing reduced by 100%.
Duration: 60 seconds
View on swtor.jedipedia.net Penalty of Destiny, reducing all outgoing damage and healing, as well as any incoming healing by 100%.

If the group is incomplete, somebody has to take two bosses. This is done by letting the spare boss roam around the room until said player finished their first duel who then engages the second boss.

The duels themselves are basically dummy parses. The Assassins regularly channel Attack and Damage Type: Melee, Energy

5 Soa

Soa, an ancient Rakatan warlord, is the last boss in the Eternity Vault. He is the most difficult encounter in the Operation with his main mechanic that lets the inner rings of the platform disappear when his health reaches certain percentages.

Pre-fight

Sometimes, the encounter starts as soon as a players enters Soa’s chamber. Therefore, the group should wait in front of the entrance of the chamber until everyone is ready.

Phase 1: Top Floor, Soa 100% - 75%

Soa will start shielded; the shield will remove itself after a few seconds.

The only noteable mechanic on the top floor is Attack and Damage Type while standing in the green AoE: Force, Energy (AoE)
View on swtor.jedipedia.net Force Torrent, “activating” one of the nodes on the outer ring. The node will start to glow green, damaging anyone standing in the green area.

At 75%, Soa will shield again and soon after, all rings of the platform, except the outer one, will fall down. While this is usually announced by Soa saying “I have waited twenty thousand years, but I will wait no longer!”, it can happen that DPS is so high that he has not even finished his introduction speech.

Everyone should stand near the entrance of the room when the inner rings collapse. Else they will die from fall damage and may land somewhere where they cannot be revived.

Transistion Phase

The group has to jump down the platforms to get to the middle floor. New platforms to jump on will appear little by little. The platforms will fall down after a certain time, so the group should not waste too many time on a platform.

Soa will gain 5 stacks of the buff Increases Soa’s damage and allows Soa to use his Power Orb Detonation ability.
View on swtor.jedipedia.net Power Orbs at the beginning of the Transistion Phase. The stacks increase his damage dealt by 5% and for each stack that is still present in the next phase, he will cast Attack and Damage Type: Force, Energy
View on swtor.jedipedia.net Power Orb Detonation, dealing high raid wide damage in the beginning of the phase until the stacks are gone. To remove stacks, the group must destroy five of the Ancient Power Sources on the platforms while jumping down; each destroyed Ancient Power Sources removes one Increases Soa’s damage and allows Soa to use his Power Orb Detonation ability.

Transistion Phase

Same procedure as in the first Transistion Phase.

Phase 3: Bottom Floor, Soa 30% - 0%

The mechanics of the middle floor are also on the bottom floor.

In addition to that, Soa remains shielded. The only way to remove the shield is to position him under the objects that he regularly hurls on the ground with Hurls a large object at the designated region.
