What is the best artifact set for a reaction-based DPS in Spiral Abyss in Genshin Impact?

For a reaction-based DPS in the Spiral Abyss, the best artifact set depends on the type of reactions you are focusing on. The most common reaction-based DPS builds revolve around Vaporize, Melt, Electro-Charged, Overloaded, and Swirl reactions. Each of these reactions benefits from specific artifact sets and team compositions to maximize damage output. Below is a detailed explanation of how to optimize a reaction-based DPS for the Spiral Abyss, including mechanics, strategies, and recommendations.

1. Detailed Explanation of Mechanics:
Reaction-based DPS relies heavily on triggering elemental reactions to deal damage. The most powerful reactions for DPS are Vaporize and Melt, as they scale multiplicatively with your character's stats. Vaporize occurs when Hydro meets Pyro (or vice versa), and Melt occurs when Pyro meets Cryo (or vice versa). These reactions amplify the damage of the triggering attack by 1.5x or 2x, depending on the order of elements applied. Other reactions like Electro-Charged, Overloaded, and Swirl deal damage based on the character's Elemental Mastery and level, making them more consistent but less bursty than Vaporize or Melt.

2. Step-by-Step Instructions or Strategies:
To maximize reaction damage, you need to ensure that your DPS character is the one triggering the reaction. For example, if you are using a Pyro DPS like Hu Tao or Diluc, you want to apply Hydro first with a character like Xingqiu or Yelan, then use your Pyro attacks to trigger Vaporize. Similarly, for a Cryo DPS like Ayaka or Ganyu, you want to apply Pyro first with a character like Bennett or Xiangling, then use Cryo attacks to trigger Melt. This ensures that your DPS character benefits from the reaction multiplier.

3. Important Tips and Considerations:
Elemental Mastery is a crucial stat for reaction-based DPS characters, as it increases the damage of reactions. However, you should balance Elemental Mastery with other stats like Crit Rate, Crit Damage, and Attack. For Vaporize and Melt DPS, Crit stats are more important because the reaction multiplier scales with your character's damage. For Electro-Charged or Overloaded DPS, Elemental Mastery is more important because the reaction damage is based on your level and Elemental Mastery.

4. Common Mistakes to Avoid:
One common mistake is not applying the correct element first. For example, if you use Pyro before Hydro, you will trigger a weaker Vaporize reaction (1.5x instead of 2x). Another mistake is neglecting energy management. Reaction-based teams often rely on frequent Elemental Bursts to apply elements consistently, so make sure your characters have enough Energy Recharge to maintain uptime.

5. Advanced Techniques or Optimizations:
Advanced players can optimize their rotations to ensure maximum reaction uptime. For example, in a Vaporize team with Xingqiu and Hu Tao, you can use Xingqiu's Elemental Burst before switching to Hu Tao, then use her Elemental Skill to trigger Vaporize on every attack. You can also use Anemo characters like Sucrose or Kazuha to swirl elements and increase Elemental Mastery for the team, further boosting reaction damage.

6. Team Composition Suggestions:
For Vaporize teams, a strong composition is Hu Tao, Xingqiu, Sucrose, and Zhongli. Hu Tao is the main DPS, Xingqiu provides consistent Hydro application, Sucrose boosts Elemental Mastery, and Zhongli provides shields and resistance shred. For Melt teams, a good composition is Ganyu, Bennett, Xiangling, and Diona. Ganyu is the main DPS, Bennett and Xiangling provide Pyro application, and Diona offers healing and shields.

7. Artifact and Weapon Recommendations:
For Vaporize or Melt DPS, the best artifact set is Crimson Witch of Flames (for Pyro) or Blizzard Strayer (for Cryo). These sets increase reaction damage and provide useful bonuses like Pyro or Cryo damage. For Electro-Charged or Overloaded DPS, the Thundering Fury set is ideal, as it boosts Electro damage and reduces cooldowns. Weapons should focus on increasing Crit Rate, Crit Damage, or Elemental Mastery. For example, Staff of Homa is excellent for Hu Tao, while Skyward Harp works well for Ganyu.

8. Specific Examples and Scenarios:
In Floor 12 of the Spiral Abyss, you might face enemies with high Pyro or Cryo resistance. In this case, a Vaporize team with Hu Tao and Xingqiu can bypass these resistances by focusing on Hydro damage. Alternatively, a Melt team with Ganyu and Bennett can deal massive damage to Cryo-resistant enemies by triggering Melt reactions. Always adapt your team and strategy based on the enemy lineup and elemental resistances.

By following these strategies and recommendations, you can optimize your reaction-based DPS for the Spiral Abyss and achieve higher scores. Focus on proper element application, balanced stats, and efficient rotations to maximize your damage output.
