Halondrus the Reclaimer Strategy Guide for Sepulcher of the First Ones

In the Stationary Phase:

• Spread out around the boss, and soak the orbs that move toward the boss from the edge of the room to knock them away. On Heroic,the orbs have a shield on them that needs to be removed with the tank frontal beam before they can be soaked ( Fractal Shell). If an orb gets to the boss, it is basically a wipe.
• Tanks taunt swap after every beam cast, being sure to aim it at orbs on Heroic ( Lightshatter Beam).
• Dispel the Crushing Prism as soon as possible to prevent its damage from ramping up, but on Heroic, players with the debuff need to move in front of where orbs are spawning and before getting dispelled. This leaves a circle on the ground that slows the orbs.
• At 100 Energy, the boss shields itself and starts pulling everyone and the orbs toward it. Nuke the shield as fast as possible to break it and stop the pull.
• When everyone gets a circle around them, spread out and then move out of the aftershock that spawns where the circle expires ( Earthbreaker Missiles).
• On Heroic, dodge the rotating circles on the ground ( Planetcracker Beam). In the final phase, quickly move through it instead.

In the Relocation Phase (80% and 50%):

• Quickly move with the boss as it moves to the next room, and continue doing damage to it as you go.
• Avoid standing in the big circles on the ground, because they do lethal damage to anyone inside when they explode ( Shatter). They also knock everyone away from them when they explode, so try to use this to get knocked forward instead of backward.
• The raid takes crazy pulsing damage, so healers be ready to heal on the move.

Halondrus is an entirely single-target fight with a high mobility requirement. There are two alternating phases: the Stationary Phase where the boss fights you and you have to soak a bunch of orbs, and the Relocation Phase where the boss runs to the next room and you have to run with him. We recommend using Bloodlust/ Heroism in the last Stationary Phase, because it is the longest part of the fight and can the orbs can get overwhelming.

• The fight mainly revolves around orbs that spawn from tremors around the outer edge of the room. These orbs move toward the boss and basically wipe you if even one gets to him ( Ephemeral Eruption). Players can knock orbs back by running into them, doing damage to the player in the process( Ephemeral Burst). Everyone should spread out around the boss to keep any orbs away. On Heroic, some of the orbs have a shield on them that needs to be removed before they can be soaked by hitting them with the tank frontal beam.
• Tanks taunt swap after every Lightshatter Beam cast, because it does a ton of damage to whoever it hits and increases their damage taken by the next cast. On Heroic, make sure to aim the beam at any orbs that have shields on them.
• At 100 Energy, the boss puts a big absorb shield on itself and starts pulling the raid and the orbs toward it until the shield is broken ( Reclaim). This pull gets stronger the longer the shield lasts, and it also does ramping damage to the raid, so nuke the shield as fast as possible.
• When everyone in the raid gets a circle under their feet, spread out to avoid cleaving each other ( Earthbreaker Missiles). Then move out of the aftershock that spawns from the circle when it expires.
• Healers dispel the Crushing Prism debuff on multiple players as quickly as possible, because its DoT damage and slow ramp up fast. On Heroic, players with the debuff need to position themselves in front of one of the tremors that spawns the orbs before getting dispelled. This is because dispelling the debuff drops a circle on the ground that slows the orbs, giving you more time to hit them with the tank beam and soak them.
• On Heroic, dodge the circles on the ground that rotate around the boss ( Planetcracker Beam). In the last phase, there are too many too dodge, so just move through them quickly when they get to you.
• When the boss gets to 80% and 50% health, it starts the Relocation Phase.

• The boss despawns all the orbs, stands up, and starts moving to the next room. Follow the boss as fast as possible and continue doing damage to him as you go. Healers also need to be ready to heal on the move, because the raid takes huge pulsing damage while the boss is moving ( Quaking Steps).
• There are circles on the ground along the way that explode shortly after the boss moves past them ( Shatter). Stay out of the circles, and try to be ahead of them, because they also knock everyone away when they explode.
• Continue dispelling Crushing Prism as fast as possible and spreading for Earthbreaker Missiles.
• When the boss gets to the center of the next room, he plops down and starts the Stationary Phase again.
