What is the best way to deal with the Perpetual Mechanical Array in Genshin Impact?

The Perpetual Mechanical Array is one of the more challenging bosses in Genshin Impact, found in Inazuma. This boss is a large mechanical construct with multiple phases and mechanics that require careful strategy to defeat efficiently. Understanding its mechanics and preparing the right team and gear are essential for success.

The Perpetual Mechanical Array has two main phases. In the first phase, it is invulnerable to damage, and you must destroy its four smaller constructs, called Ruin Sentinels, to break its shield. These Ruin Sentinels are smaller versions of the boss and have their own attack patterns. Once all four are destroyed, the boss enters its second phase, where it becomes vulnerable to damage. However, it will periodically summon more Ruin Sentinels to repair itself, so you must destroy these quickly to prevent the boss from regaining its shield.

To deal with the Perpetual Mechanical Array effectively, start by focusing on the Ruin Sentinels in the first phase. These constructs are weak to elemental reactions, so using characters with strong elemental abilities is key. Characters like Hu Tao, Diluc, or Yoimiya for Pyro, Ayaka or Ganyu for Cryo, and Raiden Shogun or Fischl for Electro are excellent choices. These characters can trigger reactions like Melt, Vaporize, or Overload, which deal significant damage to the Ruin Sentinels. Once the Ruin Sentinels are destroyed, the boss will enter its vulnerable phase.

During the second phase, the boss will attack with powerful melee strikes and energy beams. Dodging these attacks is crucial, as they can deal heavy damage. The boss will also summon additional Ruin Sentinels to repair itself. These must be destroyed quickly to prevent the boss from regaining its shield. Using characters with high burst damage, such as Eula or Xiao, can help you take down the Ruin Sentinels and the boss quickly.

One common mistake is ignoring the Ruin Sentinels during the second phase. If you focus solely on the boss, it will eventually repair itself and regain its shield, forcing you to repeat the first phase. Always prioritize destroying the Ruin Sentinels as soon as they appear. Another mistake is not using elemental reactions effectively. The Ruin Sentinels and the boss are both weak to elemental damage, so using characters with strong elemental abilities and reactions is essential.

For advanced techniques, consider using characters with crowd control abilities, such as Venti or Kazuha, to group the Ruin Sentinels together. This makes it easier to destroy them quickly with area-of-effect attacks. Additionally, using characters with shields, like Zhongli or Diona, can help you survive the boss's powerful attacks. Timing your bursts and abilities to maximize damage during the boss's vulnerable phase is also important. For example, using Bennett's burst to boost your team's attack before unleashing your main DPS's burst can significantly increase your damage output.

Team composition is crucial for this fight. A balanced team with a strong DPS, a support character, and a healer or shielder is recommended. For example, a team of Hu Tao, Xingqiu, Zhongli, and Bennett is highly effective. Hu Tao provides strong Pyro damage, Xingqiu enables Vaporize reactions, Zhongli offers shielding and crowd control, and Bennett provides healing and attack buffs. Another effective team is Ayaka, Mona, Kazuha, and Diona. Ayaka deals high Cryo damage, Mona enables Freeze reactions, Kazuha groups enemies and boosts elemental damage, and Diona provides healing and shielding.

Artifact and weapon choices should focus on maximizing your DPS characters' damage. For Pyro characters like Hu Tao, the Crimson Witch of Flames set is ideal, while Cryo characters like Ayaka benefit from the Blizzard Strayer set. Weapons like the Staff of Homa for Hu Tao or the Mistsplitter Reforged for Ayaka are excellent choices. Support characters should focus on energy recharge and elemental mastery to enhance their abilities and reactions.

In summary, defeating the Perpetual Mechanical Array requires a combination of strong elemental reactions, careful timing, and effective team composition. Prioritize destroying the Ruin Sentinels, use elemental reactions to maximize damage, and avoid common mistakes like ignoring the Ruin Sentinels during the second phase. With the right strategy and preparation, you can defeat this challenging boss and claim its valuable rewards.
