Genshin Impact: How To Defeat Perpetual Mechanical Array Boss Guide

The Perpetual Mechanical Array is an Automaton World Boss in Genshin Impact. It is said that he was a war machine left behind by a nation that was already destroyed. It is composed of several cubic parts that can adapt to its surroundings.

Where is the Perpetual Mechanical Array Located?

It is located north of Narukami Island, Inazuma, in an Underwater cave. Assuming you haven’t unlocked the teleport waypoint near it, the easiest way to access it is by teleporting to Jinren Island and then using an electrogranum to access a portal that teleports you straight to the boss.

The second way is through underground ruins in Araumi. You need to complete the puzzles in ruins to make the water level go down; this allows you to gain access to the Teleport Waypoint near the Ruin Machine, which is the Perpetual Mechanical Array.

How to Gain Quick Access to The Perpetual Mechanical Array?

As said earlier, the Perpetual Mechanical Array challenge can be accessed through a portal on Jinren Island or an underground teleport waypoint. However, to unlock this teleport waypoint, the player must complete only the first part of the world quest, Sacred Sakura Cleansing Ritual. This quest will unlock the Araumi underground ruins, which can be used to access the teleport waypoint.

Note: If you need to know how to get out of the arena of the Perpetual Mechanical Array quickly, there should be an opening in a wall of the arena with stairs on the other side, or you could simply teleport away using your map.

Tips to Fight Perpetual Mechanical Array

• Do not use Physical damage characters like Eula. The boss has very high resistance to Physical attacks in both states. 
• Take with you a consistent healer or a good shielder.
• The attacks of the Mechanical Array are much faster than usual bosses, so conserve your stamina to dodge quickly.
• Bring characters with greater elemental damage and utilize reactions like Melt, Vaporize, and Aggravate.
• Save your strongest attack or ultimate for when the Perpetual Mechanical Array is paralyzed, do not use it hastily.

Perpetual Mechanical Array Attacks and Counters

The Perpetual Mechanical Array has little variety in terms of attacks and abilities. However, its attacks are faster than most other bosses and deal much more significant damage.

Note: Most of the Ability names below are unofficial.

Rocket Dive

Transforms into a mini rocket and flies upwards. Then an attack radius appears on the ground, onto which the rocket dives down, attacking the player. This attack deals with 91.6% ATK damage. To dodge this, dash away from the attack radius as soon as it appears on the ground.

Cubic Roll

Turns into a cube with a barrier around it. It quickly rolls toward the player, and when it catches up, it emerges from the cube form and releases a shockwave. This shockwave deals 75% ATK as Physical DMG. It only uses this move at long ranges. The only way to avoid this attack is by using a dash I-frame at the time of the shockwave or a shield.

Orbital Strike

The boss charges up with one of its cube parts at the top shaped like a cone, after which an attack radius appears on the player’s position. It launches a huge beam that comes down at the player’s position. This attack deals 100% ATK as Physical DMG on hit. To dodge this, dash away from the attack radius as soon as it appears.

Mechanical Sword Slash

Transforms into a giant sword. It slashes from right to left, dealing 75% ATK as Physical DMG. It only uses this move at melee ranges. To avoid this attack, dash towards the right side when the sword is about to slash.

Spinning Blade

The boss transforms into a giant spinning blade that attacks in a zig-zag pattern, going left and right once. This attack deals 58.3% ATK as Physical DMG. To avoid this, dash to the ride side when the boss is about to attack.

Energy Cannon

It charges up and then fires a beam that follows the player while dealing 33.3% ATK as constant Physical DMG as long as it touches the player. To avoid this, simply keep running away until the attack stops. One way to cancel this attack is to run behind the boss.

Defensive Stance

Launches out four cubes around it and shields itself. It is now immune to all damage. The four launched cubes transform into Ruin Machines, one of which will be highlighted by a yellow/golden aura. Attack the highlighted Ruin Machine and defeat it to paralyze the Perpetual Mechanical Array. Once paralyzed, all of its resistance is significantly reduced. This Defensive Stance is only triggered when the boss is 35% HP or lower. It can only be damaged to 30% HP.

Strategy To Defeat Perpetual Mechanical Array Easily

Most of the attacks from the boss are easy to dodge. Remember to keep using Elemental Attacks and not Physical Attacks; this means refraining from using physical melee attacks when near the boss, as it will not be helpful. When the boss is performing its Energy Cannon attack, which is hard to dodge, running behind the boss could be beneficial as it will cancel the attack.

When the boss reaches 35% HP or 30% HP, it will go into its defensive mode, where the Perpetual Mechanical Array will have a barrier and summons four Ruin Machines. Defeat the highlighted machine to paralyze the boss and reduce its damage resistance by 50%. Use this opportunity to finish its remaining HP and end the fight; dump in everything you have during this time. Remember to save your best ultimate for the paralyzed state or charge it while fighting the Ruin Machines. The Ruin Machines share the same level as the boss. If the boss is not defeated and wakes up from the paralyzed state, it absorbs all the Ruin Machines it released and continues its attack patterns like at the beginning of the fight.
