What is the best way to use Elemental Reactions against the Perpetual Mechanical Array in Genshin Impact?

The Perpetual Mechanical Array is one of the most challenging bosses in Genshin Impact, requiring a solid understanding of elemental reactions and combat mechanics to defeat efficiently. This boss is highly resistant to physical damage, so relying on elemental reactions is crucial for dealing significant damage. HereÔÇÖs a detailed guide on how to use elemental reactions effectively against the Perpetual Mechanical Array.

First, letÔÇÖs understand the boss mechanics. The Perpetual Mechanical Array has two phases. In the first phase, it summons smaller constructs that you must defeat to expose its core. In the second phase, the boss becomes more aggressive, and you need to focus on dealing damage while avoiding its powerful attacks. The boss is weak to Electro and Cryo elements, making these elements particularly effective for triggering reactions.

To maximize damage, you should focus on reactions like Superconduct, Overloaded, and Electro-Charged. Superconduct reduces the enemyÔÇÖs physical resistance, which is less useful here since the boss is resistant to physical damage. However, Overloaded and Electro-Charged are highly effective. Overloaded deals AoE Pyro damage, which is great for clearing the smaller constructs quickly. Electro-Charged deals continuous Electro damage over time, which is useful for sustained damage against the boss.

For team composition, you should include characters that can apply Electro and Pyro elements consistently. A good team might include Fischl or Raiden Shogun for Electro application, Xiangling or Bennett for Pyro application, and a Cryo character like Kaeya or Rosaria for additional reactions. A healer like Bennett or Barbara is also recommended to sustain your team during the fight.

Start the battle by applying Electro to the boss using FischlÔÇÖs Oz or Raiden ShogunÔÇÖs skill. Then, use XianglingÔÇÖs Pyronado or BennettÔÇÖs skill to trigger Overloaded reactions. This will deal significant AoE damage and help clear the smaller constructs quickly. Once the core is exposed, focus all your damage on it. Use your Cryo character to apply Cryo and trigger Superconduct, which will slightly reduce the bossÔÇÖs resistance, though this is less impactful here.

Artifacts and weapons play a crucial role in optimizing your damage. For Electro characters like Fischl or Raiden Shogun, the Thundering Fury set is ideal as it boosts Electro damage and reduces skill cooldowns. For Pyro characters like Xiangling or Bennett, the Crimson Witch of Flames set is recommended to enhance Pyro damage and reaction damage. Weapons like The Stringless for Fischl or Engulfing Lightning for Raiden Shogun can significantly boost their effectiveness.

One common mistake is neglecting to dodge the bossÔÇÖs attacks. The Perpetual Mechanical Array has powerful AoE attacks that can quickly deplete your health. Always be ready to dodge and use your healerÔÇÖs abilities to keep your team alive. Another mistake is focusing too much on physical damage. Since the boss is resistant to physical damage, prioritize elemental reactions instead.

Advanced techniques include timing your bursts to coincide with the bossÔÇÖs vulnerable phases. For example, use Raiden ShogunÔÇÖs burst when the core is exposed to maximize damage. Additionally, managing energy recharge is crucial. Ensure your characters have enough energy to use their bursts frequently by using energy recharge artifacts and weapons.

In summary, defeating the Perpetual Mechanical Array requires a well-coordinated team that can consistently trigger powerful elemental reactions. Focus on Overloaded and Electro-Charged reactions, use characters like Fischl, Raiden Shogun, Xiangling, and Bennett, and equip them with the right artifacts and weapons. Always be mindful of the bossÔÇÖs attacks and manage your energy effectively. With these strategies, you can efficiently take down the Perpetual Mechanical Array and reap the rewards.
