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

Collei is a 4-star Dendro character in Genshin Impact who excels as a support or sub-DPS, primarily focusing on applying Dendro for elemental reactions and providing utility to the team. To maximize her potential, itÔÇÖs important to choose the right artifact sets, weapons, and team compositions. HereÔÇÖs a detailed guide on how to build Collei effectively.

First, letÔÇÖs discuss the best artifact sets for Collei. The Deepwood Memories set is one of the most recommended options for her. This set provides a 15% Dendro DMG bonus with its 2-piece effect and reduces the Dendro RES of enemies by 30% for 8 seconds when her Elemental Skill or Burst hits them. This is particularly useful for teams that rely on Dendro reactions, as it amplifies the damage output of both Collei and her teammates. Another strong option is the Gilded Dreams set, which increases Elemental Mastery and provides ATK or EM bonuses based on the number of party members with the same or different elements. This set is ideal if Collei is being used in a reaction-heavy team, as it boosts her ability to trigger powerful Dendro reactions like Bloom, Hyperbloom, or Spread.

For main stats, prioritize Elemental Mastery on the Sands, Dendro DMG Bonus on the Goblet, and Crit Rate or Crit DMG on the Circlet. If Collei is being used primarily for support, Energy Recharge on the Sands can also be a viable option 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 enhance her ability to trigger reactions and deal consistent damage.

When it comes to weapons, Collei benefits greatly from bows that provide Energy Recharge or Elemental Mastery. The Elegy for the End is an excellent 5-star option, as it increases Energy Recharge and provides an ATK and Elemental Mastery buff to the team when her Elemental Burst is used. For 4-star options, the Favonius Warbow is a solid choice, as it generates energy particles and helps with Energy Recharge. The Stringless is another great option, as it increases Elemental Skill and Burst DMG while also boosting Elemental Mastery. If youÔÇÖre using Collei as a sub-DPS, the Sacrificial Bow can 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. Pairing her with Hydro characters like Xingqiu or Yelan can create Bloom reactions, while Electro characters like Fischl or Raiden Shogun can trigger Quicken, Aggravate, or Spread reactions. A popular team composition is Collei, Fischl, Xingqiu, and a healer like Kokomi or Bennett. This setup allows for consistent Dendro application and strong elemental reactions. Another effective team is Collei, Raiden Shogun, Yelan, and Zhongli, which provides both damage and survivability.

When building Collei, itÔÇÖs important to avoid common mistakes such as neglecting her Energy Recharge or focusing too much on ATK. Since her role is primarily to apply Dendro and support the team, her personal damage output is less important than her ability to enable reactions. Additionally, make sure to level her Elemental Skill and Burst, as these are her primary sources of Dendro application. Her Normal Attack talent can be left at a lower level unless youÔÇÖre using her as a main DPS, which is less common.

Advanced techniques for optimizing Collei include timing her Elemental Skill and Burst to maximize Dendro application. Her Elemental Skill, Floral Brush, can be aimed to hit multiple enemies, while her Elemental Burst, Trump-Card Kitty, creates a field that continuously applies Dendro. Using these abilities in conjunction with other charactersÔÇÖ skills can create powerful reaction chains. For example, using ColleiÔÇÖs Burst followed by FischlÔÇÖs Oz can trigger multiple Spread reactions, significantly increasing damage output.

In summary, Collei is a versatile Dendro support character who shines in teams that rely on elemental reactions. By equipping her with the Deepwood Memories or Gilded Dreams artifact sets, focusing on Elemental Mastery and Energy Recharge, and pairing her with characters that complement her abilities, you can maximize her potential. Avoid common mistakes like neglecting Energy Recharge or over-investing in ATK, and focus on enabling reactions to make the most of her kit. With the right build and team composition, Collei can be a valuable asset in both exploration and challenging content like the Spiral Abyss.
