Dungeon Walkthrough
As you make your way through this dungeon, be on the lookout for floating clouds of yellow Corruption. Moving near one of these will deal damage in the area, so avoid getting close to the yellow clouds.
In the second section of Pharos Sirius (Hard), you will encounter small Time Bomb enemies. These enemies will instantly begin casting Self-destruct when they are targeted, dealing high damage in the surrounding area. Avoid these large AoEs as you move through the dungeon.
Additionally, Simple Bomb Incubators will periodically summon Time Bombs nearby. Destroy the Bomb Incubators as quickly as possible to reduce the amount of AoEs.
In the room before the final boss, there will be several Simple Bomb Incubators that will summon Time Bombs, as well as various other enemies. All of these enemies will attempt to destroy the Pharos Walls, which, if successful, will summon even more enemies to the area. Destroy the Incubators first, then focus on the enemies attacking the Walls.
Ghrah Luminary
The first boss of Pharos Sirius (Hard) is Ghrah Luminary. You may notice a number of untargetable bird and spider adds roaming around the arena. These will come into the fight later on.
- Vorpal Blade: Deals damage in a short cone to the front of the boss. The Tank should face Ghrah Luminary away from the rest of the party.
- Luminous Lancet: Targets all players with AoE circles. Move outside the AoE indicators to avoid.
- Prey and Corruption: Yellow Corruption orbs will appear around the arena, and will tether to random players. After a few seconds, the Corruption orb will attempt to corrupt its current target, summoning an enemy. What type of Corruption enemy is summoned depends on the orb's current target.
- Player: If the Corruption orb is targeting a player, a doll-shaped Corruption will be summoned that tethers to the boss, granting it a damage up buff and occasionally using AoE attacks.
- Spider: If the Corruption orb is tethered to a spider, it will kill the spider, creating a poison puddle at its position. Then, a Corrupted Spider will appear, which will also drop a poison puddle upon death.
- Bird: If the Corruption orb is tethered to a bird, it will kill the bird and summon a Corrupted Bird in its place.
- To best deal with this mechanic, move your tether to one of the bird adds around the arena. These are easy to kill once Corrupted, and have no additional effects.
Ghrah Luminary will repeat these attacks until it is defeated. Look for a bird add to move your Corruption tether to, and heal through the rest of the Ghrah Luminary's attacks.
8th Order Patriarch Be Gu
The second boss of Pharos Sirius (Hard) is Be Gu, who will use the following attacks and mechanics.
- Frack: Deals damage in a short line AoE to the front of the boss. The Tank should use defensive cooldowns as necessary to mitigate this damage.
- Strip Mine: Creates a proximity-based AoE in the center of the arena that deals more damage the closer you are to the AoE. Run to the edge of the arena to mitigate the damage of this attack. After Strip Mine deals damage, an Aether Valve will be opened.
- Aether Valves: Periodically summons Corrupted Gel enemies that will target and attack random players. As long as the Valve remains open, these enemies will continue to spawn. To stop this, kill a Corrupted Gel on top of the Aether Valve to seal it shut.
- Corrupted Gel: Attacks random players. If left alive for long enough, the Corrupted Gel will cast Corrupture, dealing high damage to all party members. Destroy them before this happens.
- Alchemy Engine: These adds will spawn around the arena and tether to the boss, granting Be Gu a damage increase buff and allowing it to counter all attacks, stunning players that attack them. While the Alchemy Engine is alive, the boss will repeatedly attack with Loose Screw.
- Loose Screw: Be Gu will charge towards random players, dealing damage along its path. When the boss turns to attack with Loose Screw, quickly move out of the way.
- Furnaceman Adds: These adds will spawn at the same time as the Alchemy Engine, and will use Titan's Anger on random players, attacking with a circle AoE. Move out of the AoE indicator to avoid while destroying the Alchemy Engine.
Be Gu will repeat these attacks until it is defeated. There's a lot to keep track of during this fight, but be sure to kill the Corrupted Gels on top of the Aether Vents, and destroy the Alchemy Engine as quickly as possible.
Progenitrix and Progenitor
The final boss of Pharos Sirius (Hard) is Progenitrix, followed by Progenitor. These two bombs will use the following attacks and mechanics.
Progenitrix
- Scalding Scolding: Deals damage in a wide cone to the front of the boss. The Tank should face the boss away from the rest of the party to avoid them taking unecessary damage.
- Sap: Targets a random player with a large circle AoE. Move outside the AoE indicator to avoid.
- Bombshell Drop: Progenitrix will summon two types of bombs, detailed below.
- Grey Bombs: These enemies will slowly grow in size. When at maximum size, they will cast Big Burst, dealing high damage to all party members. Destroy the Grey Bombs before this happens.
- Lava Bombs: These enemies will periodically cast Fire on a random target, dealing a small amount of damage. Defeat them after first dealing with the Grey Bombs.
- Big Burst: Deals damage to all party members and summons four Grey Bombs. Destroy them as quickly as possible.
Progenitrix will repeat these attacks until it is defeated, at which point Progenitor will be summoned.
Progenitor
After Progenitrix has been defeated, Progenitor will take the field, using Scorched Earth to deal damage to all players and knock them back to the bottom of the arena. Progenitor will use Scalding Scolding, and Sap, as well as a few additional attacks and mechanics.
- Blue Flame: Deals fire damage to all party members and inflicts a fire vulnerability up debuff, increasing the amount of fire damage all players take. This debuff will stack throughout the fight as Progenitor continues to use Blue Flame, making the attack deal more damage as the fight continues.
- Big Burst: Deals fire damage to all party members and summons Grey Bombs and Remedy Bombs. The Grey Bombs function like they did before, while the Remedy Bombs will tether to the Grey Bombs, slowly moving towards them. When a Remedy Bomb reaches a Grey Bomb, it will explode, dealing fire damage to all party members and inflicting Burn, dealing damage over time. Destroy the Remedy Bombs before they reach the Grey Bombs.
Progenitor will repeat these attacks until it is defeated. As the fight progresses, more Grey and Remedy Bombs will be summoned at once, and Blue Flame's damage will continue to increase. Destroy the bombs and work quickly to defeat Progenitor before it defeats you.
