Bulky Iron Chunk Luxurious Chest Guide in Genshin Impact

Before you can even get to the location where the boss is, you need to first destroy 16 stone pillar seals. You can find the locations of these seals in our Genshin Impact: Legends of the Stone Lock Guide. After you have successfully found all 16 stone locks, you will automatically obtain this quest.

Head over to this location on the map:

Here, you’ll find that there’s no longer any water inside. Once you get there, simply drop all the way down and simply follow the quest indicating the location of the seal.

After that, you’ll then get the Challenge the Bulky Iron Chunk quest. For this one, you need to first hit the three stone pillars using a Pyro attack. After destroying the pillars, it will then unleash the Perpetual Mechanical Array boss.

Once you have defeated the boss, you want to interact with the onion-looking structure in the corner of the room. Play the Rhythm of the Great Dream song, then talk to Arayuta, Arasata, and Aradashan afterward.

Simply finish the dialogue and choose the Sure option to fight the boss once again. Then, talk to Aradashan, Arasaha, and Arayuta. This time, Arayuta will be the one to ask you if you still want to go. Fight and defeat the boss once again. You’ll then get an Exquisite Chest as a reward.

Then, talk to Arasata and enter the boss fight for the third time. Defeat it and obtain a Precious Chest. Finally, talk to Arasaha to fight the boss one last time. Defeat it, and you can then get a Luxurious Chest as a reward.
