#11 Connect the circuit
Inside the large room, you will find several relays all over the area that connects to one control device. However, some of them are frozen and are unable to gain electricity.
You will need to find 2 Farrwicks, which are essentially Dendro heaters as they will melt the ice away from the relays. Place one Farrwick between two frozen relays, making it easier to get the electricity flowing.
Once you have the two Farrwicks placed strategically, you will now need to rotate the relays around until the electricity hits the control device. Once the control device is lit up, Nasajune will call you back.
#12 Enter the proving ground and activate the Ruin Cannon
This is where combat starts to happen. After meeting up with Nasajune again, your next objective is to enter the proving ground and activate the Ruin Cannon.
Cutscenes will play out until it’s time to fight. You will have enemies coming at you while towers fire range attacks at you.
The towers will telegraph their attacks pretty clearly. However, you won’t have a place to hide if they all attack at the same time. This is when the Dendro shields appear. They will pop up when the towers get ready to strike, so use the time to run inside the dome and wait until the towers stop.
More enemies will come in after every tower attack. Keep doing it until all waves are finished.
After the attack, the Ruin Cannon can now be used. Use it to destroy the Golem’s Core. The core is shielded and will be moving around. You will have to shoot the 3 balls on the corners to get rid of the shield.
The Golem’s Core will take a while to take down, and you will have to take down the shields a couple of times before the core is destroyed.
#13 Obtain the Great Song of Khvarena
After destroying the Golem’s Core, you can now get the Great Song of Khvarena. Make your way to it, but don’t forget the Luxurious Chest along the way.
After getting the last Great Song, leave the proving ground and talk to Nasajune.
#14 Find the final Great Song of Khvarena
Now you need to get the last Great Song of Khvarena. To do that, you need to go to the marker that is near the Gate of Zulqarnian. Use the Teleport Waypoint to get there quicker.
You will need to go down into the area to get to where the last Great Song is. Along the way, you will encounter another seal to Dispel. Just keep going forward until you meet up with Nasajune again.
#15 Use Farrwick to link the circuit and activate the left machine door
Inside the room, you will need to move the relays again to connect the power to the circuits. However, the electricity isn’t working because of the frozen power distributors.
You will need to use Farrwicks to melt the ice around them and move the relay to connect it to the control device. This will open the door on the left, and you will get a note.
#16 Look for the second Farrwick
Now that you have the left door open, you will need to open the door on the other side. The problem there is that you only have one Farrwick around.
You will need to travel deeper into the facility to find the second Farrwick, which is located underwater. Use the device near the water to drain it and pick up the Farrwick before making your trip back.
#17 Link the circuit and activate the right machine door
Now that you have two Farrwicks, we can get the right machine door open. Simply place a Farrwick on each power distributor and move the relays around until the power can reach the control device that allows the door to open.
#18 Look for the third Farrwick
Now that you have the second door open, you will need to go in and find a third Farrwick for the next puzzle. Go through the door that just opened and fight through until you see the third Farrwick here. Once you have it, head back to the area.
#19 Connect the three devices near the elevator
Back in the room, you can now use the last Farrwick to unfreeze the last power distributor. With all three up and running, move the relays around until they all align themselves behind a device. This will power the elevator.
#20 Activate the central control device
Once you have all three devices powered up, go up using the Dendro lifts to activate the central control device. Use the image above to get the correct answer on what symbol needs to be present.
#21 Obtain the final Great Song Khvarena
Take the elevator down and you will have to fight a boss. This one isn’t too hard and you can easily dispatch it with haste.
Once it’s gone, you will then need to use Sorush to collect the last Great Song. Mission accomplished, right? Not yet.
After a brief conversation with Nasajune, who turns out to be crazy, you will have to fight him and Klingsor. Surprisingly, they are just as easy to beat as the last boss. Once you have dwindled Nasajune’s health down, he will escape the fight. This leads to a cutscene and the quest completion.
