How to Defeat Perpetual Mechanical Array

Use Elemental Attacks

We recommend bringing characters who can deal Elemental DMG more often than not. Defeating the Perpetual Mechanical Array will be a lot quicker especially with the Melt or Vaporize reactions.

Defense Mode

When the Perpetual Mechanical Array loses a certain amount of HP, it will go on the defensive and protect itself with a barrier while summoning four Ruin Enemies.

You must defeat the marked Ruin Enemy for the Perpetual Mechanical Array to get out of its Defense Form. Unmarked Ruin Enemies will take no DMG so focus on attacking the marked one.

Use your Strongest Attacks When it's Immobilized

After defeating the marked Ruin Enemy, the Perpetual Mechanical Array will lose its barrier and will be immobilized for a period of time. Go all out with your strongest attacks when it's down before it manages to get up and be able to fight.

Perpetual Mechanical Array Attack Patterns

All Mechanical Array Attacks

Laser Attack

A long-ranged laser will shoot out of the Mechanical Array and follow characters. Keep dashing to completely avoid this Laser Attack!

Laser Explosion Attack

The Perpetual Mechanical Array locks in on a target and shoots a powerful laser at their exact location. Use the short period between the target lock and the attack to dodge out of the attack's AoE!

Ruin Machine Summon

The Perpetual Mechanical array summons a Ruin Crusher, Ruin Destroyer, Ruin Defender, and Ruin Scout to fight you while the Mechanical Array itself stays dormant. Group the machines together and unleash a powerful AoE attack to damage them all at once!

Rocket Attack

The Perpetual Mechanical Array turns into a rocket and slams down onto a player. The attack's AoE is shown before the Mechanical Array hits the ground, so dodge out of it at the last minute!

Cube Attack

The Perpetual Mechanical Array turns into a cube and rushes towards the player. Keep your distance and dash out of the attack AoE to avoid getting stomped on!

Spinning Attack

The Perpetual Mechanical Array begins spinning and thrusts itself towards players. The attack's range is small, so shield up and hit it during this attack pattern!

Sword Attack

The Perpetual Mechanical Array takes the shape of a sword and swings itself at a player. The swing goes downward, so dashing to the side at the right time will easily let you avoid the attack!
