Walkthrough[edit]
- You can begin the fight against Persys, Primordial Ruin by approaching it or shooting it.
Opening the Door[edit]
- Once the fight has begun, you have 2 Incarcerator Hydras that appear, one on each side of the "safety Room."
- They appear with a number of Goblins, but also a trio of Supplicants as well, so be warned about the explosions.
- Destroy the Hydras (and at least thin the adds that came with it) to move to the next step.
- A short while after each Incarcerator Hydra is destroyed, a Conduit Minotaur will appear in the room behind the pillar against the wall on either side.
- Destroy them to drop the pool for the Arctrician buff.
- With the buff acquired from either side, it's time to open the door.
- If you look at the inside of the pillars in the middle of the room, you will see nodes on them.
- On top of that, there is a node just above the large door between the safety room and the Reactor Room.
- You need to quickly shoot the 4 nodes in the middle and then shoot the node over the door between the rooms.
Preparing the Core[edit]
- In the Reactor Room, there are 2 pairs of cores, 2 on the left side and 2 on the right side.
- Each has its own path running from the Reactor Room to the Safety Room.
- They can be completed from either direction, but starting in the Safety Room is recommended.
Circuit 1[edit]
- Start this circuit by firing on the Node on the back right pillar in the Safety Room.
- Turn to the small area where the Conduit Minotaur spawns in.
- In the corner, you will find the next Node in the Circuit.
- Run toward the Right-Hand Door to the Reactor Room.
- Look to the Ceiling Corner nearby the door to find the next Node in the Circuit.
- Run on through to the Reactor Room.
- Look on the ceiling nearby the support column on this side.
- There is a Node sitting there for you to continue the Circuit.
- Just to the central platform of the Reactor Room.
- Look back toward the walkway you just jumped from.
- Look into the gap to where you jumped from to spot the next Node in the Circuit.
- Finally, look to the Final Node in the Front Right to complete the Circuit.
Circuit 2[edit]
- This circuit being on the right-hand side of the Safety Room.
- It starts on the back of the Front Right Pillar.
- Hit the Node there to begin.
- After that, look to the left of the right-hand door to spot the next node.
- Run through the door to the Reactor Room.
- Follow the wire over to the left and look to the area below the center door.
- Between the pair of doors, almost hidden under the lip, you will find the next Node.
- Jump over to the walkway and center of the Reactor Room.
- Look just below the right-hand corner of this to find the next Node.
- Continue to the right, past the small walkway and look to the narrow area between.
- There is a pair of narrow pillars coming from below.
- Shoot the node on the back of the second pillar.
- After that, look to the node on the right closest to the back of the room.
- Hit that Node to complete the circuit.
Circuit 3[edit]
- This circuit starts on the back of the front left pillar in the middle of the Safety Room.
- From there, look to the door on the left and to the right-hand side of it.
- Between the two doors, just next to the left-hand door, is the next Node in the series.
- Follow the Wire through the Reactor Room.
- On the left-hand wall, just a short ways in, you will see the Third Node.
- Follow the wire to the gap between the outer walkway and the inner platform.
- There is a machine just on the outer part of the ring between the pair.
- Below the top part of the machine is the Fourth Node in the Circuit.
- From there, look to the final Node in the Circuit, found in the back left of the room.
Circuit 4[edit]
- This Circuit starts on the back left pillar, so shoot the Node to start the Circuit.
- Look to the room across from the first Node to find the Second Node.
- After that, look to the right to the area where the Conduit Minotaur appears.
- The Third Node is on the Ceiling of this spot.
- Continue toward the left-hand door into the Reactor Room.
- Look to the Top Left Corner of the Safety Room to spot the Fourth Node of this Circuit.
- Jump over to the central platform of the Reactor Room.
- Look to the machine in the bottom left corner of the Reactor Platform to spot the Fifth Node in the Circuit.
- Finally, look to the far left Node in the Reactor Room to complete this Circuit.
Closing the Door[edit]
- You will now have the messages, "Reactor core purge - Armed" and "Reactor Isolation Chamber Active... Take Cover".
- Rush back to the "Safety Room" to start the next part.
- Persys will rush into the Reactor Room to disable the Purge.
- Back in the Safety Room, quickly find and destroy a Conduit Minotaur.
- This will re-enable the nodes in the middle of the "Safety Room" so you can close the door.
- Get into the middle of the room or just shoot the nodes in the middle of the room on the pillars and above the large connecting door.
- You did everything right when you get the messages, "Isolation Complete".
- This part is complete when you get the messages, "Reactor core purged" and "Persys is vulnerable".
Damage Phase[edit]
- After the blast from the reactor, the door between the rooms will open again, and Persys, Primordial Ruin will be vulnerable.
- If you have a Titan with Ward of Dawn, they can use that Ward and draw the attention of Persys, Primordial Ruin.
- The rest of the fireteam can circle behind Persys and shoot the critical spot in the back.
- Pummel it at this point with everything you have.
- The damage phase ends when you see the message, "Persys overcharges its shields."
- You will need to go through this process likely 4-5 times to defeat Persys.
