How to unlock and defeat the perpetual mechanical array in Genshin Impact

The Perpetual Mechanical Array is a special world boss in Genshin Impact that releases important materials for character leveling. In particular, the boss drops the Perpetual Heart, which is used for the ascension of Kamisato Ayaka. If you are entering Inazuma for the first time, you will have to jump through a few circles to get there.

Head to Araumi's Waverider Wavepoint and take it to Jinren Island just north of you. You will reach Jinren Island and a teleport point, consisting of fairly tall rock structures and two separate mini-islands. The first largest island is where you will need to go to fight the Perpetual Mechanical Array.

The lower right part of the first island has a rock structure with an Electrogranum on it. Collect the Electrogranum and ride the Thunder Spheres to the purple portal just above you. (It looks just like the portal used to reach the Spiral Abyss for the first time.) Then, you will teleport to the Perpetual Mechanical Array.

The fight consists of two phases. The initial phase is a simple phase not unlike other world bosses. Just deal more damage to the boss and dodge his various attacks. After a certain amount of time, the boss will move on to his second phase.

Here, it will split into many different cores that will attack you. Find the core with a yellow ring around it and hit it with your attacks. Once that core is defeated, the other cores will disappear and the main boss will remain in a weakened state where he cannot attack. It will take extra damage in this state, so deal as much damage to it as possible.

Once the boss is defeated, you can collect your reward for 40 Resin. Along with the Perpetual Heart, the boss can drop the Gladiator's Finale and Wanderer's Troupe artifacts, as well as Geo and Cryo minerals.
