How do I deal with the Perpetual Mechanical Array in Spiral Abyss in Genshin Impact?

The Perpetual Mechanical Array is one of the most challenging bosses in Genshin Impact, especially when encountered in the Spiral Abyss. This boss has unique mechanics that require careful planning and execution to defeat efficiently. Below is a detailed guide on how to deal with the Perpetual Mechanical Array in the Spiral Abyss, covering mechanics, strategies, team compositions, and more.

The Perpetual Mechanical Array has two main phases. In the first phase, it is invulnerable and summons smaller constructs called Ruin Sentinels. These Sentinels must be defeated to progress to the second phase, where the Array becomes vulnerable. The Array has high resistance to physical damage, so elemental damage is key. Additionally, it has a high health pool, making time management crucial in the Spiral Abyss.

To start, focus on the Ruin Sentinels. These smaller enemies are vulnerable to crowd control and elemental reactions. Characters with area-of-effect (AoE) abilities, such as Kazuha, Venti, or Sucrose, can group them together, making it easier to deal damage. Use characters with strong elemental damage, like Hu Tao, Ganyu, or Ayaka, to quickly eliminate the Sentinels. Once all Sentinels are defeated, the Perpetual Mechanical Array will enter its vulnerable phase.

During the second phase, the Array becomes susceptible to damage but will still use powerful attacks. It has a spinning laser attack, a ground slam, and a homing missile barrage. Dodging these attacks is essential, as they deal significant damage. Characters with shields, like Zhongli or Diona, can provide protection, while healers like Bennett or Jean can sustain your team. Focus on dealing consistent elemental damage during this phase, as the ArrayÔÇÖs resistance to physical damage makes it harder to defeat with physical DPS characters.

Team composition is critical for this fight. A strong team might include a main DPS like Hu Tao or Ayaka, a sub-DPS like Xingqiu or Fischl, a support like Bennett or Kazuha, and a shielder or healer like Zhongli or Diona. This setup ensures you have both damage and survivability. For example, Hu Tao paired with Xingqiu can trigger Vaporize reactions for massive damage, while Kazuha can group enemies and boost elemental damage. Bennett provides healing and an attack buff, making him invaluable in this fight.

Artifact and weapon choices should prioritize elemental damage and energy recharge. For DPS characters, sets like Crimson Witch of Flames (for Pyro characters) or Blizzard Strayer (for Cryo characters) are ideal. Support characters benefit from Noblesse Oblige or Viridescent Venerer sets. Weapons like Staff of Homa for Hu Tao or Mistsplitter Reforged for Ayaka are excellent choices. For supports, weapons like Favonius Sword or Sacrificial Bow can help with energy management.

One common mistake is neglecting the Ruin Sentinels in the first phase. Failing to defeat them quickly will prolong the fight, making it harder to clear the floor within the time limit. Another mistake is not dodging the ArrayÔÇÖs attacks in the second phase, which can lead to unnecessary damage and team wipes. Always be mindful of your positioning and stamina management.

Advanced techniques include using elemental reactions to maximize damage. For example, pairing a Cryo character like Ayaka with a Hydro character like Mona can trigger Freeze reactions, immobilizing the Array and allowing for consistent damage. Overload reactions, triggered by Pyro and Electro characters, can also deal significant AoE damage to the Ruin Sentinels. Additionally, timing your bursts and skills to coincide with the ArrayÔÇÖs vulnerable phase can help you deal maximum damage quickly.

In summary, defeating the Perpetual Mechanical Array in the Spiral Abyss requires a well-rounded team, careful execution of mechanics, and efficient use of elemental reactions. Focus on defeating the Ruin Sentinels quickly, dodge the ArrayÔÇÖs attacks, and use strong elemental DPS characters to deal consistent damage. With the right strategy and team composition, you can overcome this challenging boss and clear the Spiral Abyss floor successfully.
