What are the best artifact sets for Collei in Genshin Impact?

Collei is a 4-star Dendro bow user in Genshin Impact who excels as a sub-DPS or support character, specializing in applying Dendro and enabling powerful elemental reactions. To maximize her potential, itÔÇÖs important to focus on her artifact sets, main stats, and team synergies. HereÔÇÖs a detailed guide on how to build Collei effectively.

First, letÔÇÖs discuss the best artifact sets for Collei. The most recommended set for her is the Deepwood Memories set. This set is ideal because it reduces Dendro resistance of enemies, which significantly boosts the damage of Dendro-based reactions like Spread, Aggravate, and Bloom. The 4-piece bonus of Deepwood Memories reduces Dendro RES by 30% for 8 seconds when an Elemental Skill or Burst hits an opponent. This effect works even if Collei is off-field, making it perfect for her role as a support or sub-DPS. If you donÔÇÖt have a full Deepwood Memories set, you can use a 2-piece combination of Deepwood Memories and Gilded Dreams or WandererÔÇÖs Troupe. These combinations provide Elemental Mastery and Dendro DMG bonuses, which are also beneficial for her.

For main stats, prioritize Elemental Mastery on the Sands, Dendro DMG Bonus on the Goblet, and Crit Rate or Crit DMG on the Circlet. Elemental Mastery is crucial for Collei because it enhances the damage of Dendro reactions, which are her primary source of damage. If youÔÇÖre using her as a support, you can also consider Energy Recharge on the Sands to ensure her Elemental Burst is available more frequently. For substats, focus on Elemental Mastery, Energy Recharge, Crit Rate, and Crit DMG. These stats will help her deal more damage and maintain consistent energy generation.

When it comes to weapons, Collei benefits from bows that provide Elemental Mastery, Energy Recharge, or Crit stats. The best 5-star option is the Elegy for the End, which increases Elemental Mastery and provides an Energy Recharge bonus. It also boosts the teamÔÇÖs ATK and Elemental Mastery when her Elemental Burst is used. For 4-star options, the Favonius Warbow is a great choice because it generates energy particles, helping Collei and her team maintain their bursts. The Stringless is another excellent option, as it increases Elemental Skill and Burst damage while providing Elemental Mastery. If youÔÇÖre using Collei as a support, the Sacrificial Bow can also be useful for resetting her Elemental Skill cooldown, allowing her to apply Dendro more frequently.

In terms of team composition, Collei works well in teams that focus on Dendro reactions. A popular team setup includes Collei, a Hydro character like Xingqiu or Yelan, an Electro character like Fischl or Raiden Shogun, and a healer or shielder like Kokomi or Zhongli. This team allows for consistent Bloom and Hyperbloom reactions, dealing massive damage over time. Another effective team is a Quicken team, where Collei pairs with an Electro character like Keqing or Yae Miko to trigger Aggravate and Spread reactions. In this setup, ColleiÔÇÖs role is to apply Dendro and enable the Electro characters to deal increased damage.

One common mistake to avoid is neglecting ColleiÔÇÖs Energy Recharge. While her Elemental Burst is powerful, it has a high energy cost, so ensuring she has enough Energy Recharge is crucial. Aim for at least 160-180% Energy Recharge to maintain consistent uptime on her Burst. Another mistake is focusing too much on ATK stats. Since ColleiÔÇÖs damage primarily comes from Dendro reactions, Elemental Mastery and Dendro DMG Bonus are more important than raw ATK.

For advanced optimizations, consider pairing Collei with characters who can trigger reactions quickly. For example, using her with a fast Hydro applicator like Xingqiu or a high-frequency Electro character like Fischl can maximize the number of reactions she enables. Additionally, timing her Elemental Skill and Burst to coincide with other charactersÔÇÖ abilities can create powerful reaction chains. For example, using her Elemental Burst right before an Electro characterÔÇÖs Burst can ensure that all hits benefit from the Dendro application.

In summary, Collei is a versatile Dendro character who shines in teams focused on Dendro reactions. Equip her with the Deepwood Memories set, prioritize Elemental Mastery and Energy Recharge, and pair her with characters who can trigger reactions effectively. By following these strategies, you can maximize ColleiÔÇÖs potential and create a powerful team capable of tackling any challenge in Genshin Impact.
