What is the best weapon for Collei in Genshin Impact?

Collei is a 4-star Dendro bow user in Genshin Impact, primarily functioning as a support or sub-DPS character. Her kit revolves around applying Dendro to enemies, enabling powerful elemental reactions like Bloom, Aggravate, and Spread. To maximize her potential, choosing the right weapon is crucial, as it directly impacts her energy recharge, damage output, and utility in team compositions.

The best weapon for Collei depends on her role in your team. If she is used as a support, weapons that boost her energy recharge or provide team utility are ideal. For sub-DPS builds, weapons that enhance her damage output or elemental mastery are more suitable. Below is a detailed breakdown of weapon options, artifact recommendations, team synergies, and strategies to optimize Collei's performance.

For support builds, the Favonius Warbow is an excellent choice. This weapon provides energy recharge as its secondary stat, ensuring Collei can consistently use her Elemental Burst, which is essential for applying Dendro and enabling reactions. The passive effect of Favonius Warbow generates energy particles when Collei scores a critical hit, further supporting her team's energy needs. Another great option is the Sacrificial Bow, which has a chance to reset the cooldown of her Elemental Skill, allowing her to apply Dendro more frequently. This is particularly useful in teams that rely on quick rotations and frequent elemental reactions.

For sub-DPS builds, the Stringless is a top-tier weapon. It increases Collei's Elemental Mastery, boosting the damage of her elemental reactions, and enhances the damage of her Elemental Skill and Burst. This makes her a strong contributor to reactions like Spread and Aggravate. Alternatively, the Windblume Ode, a free event weapon, also provides Elemental Mastery and increases attack after using her Elemental Skill, making it a solid choice for players who missed The Stringless.

Artifacts play a significant role in enhancing Collei's effectiveness. For support builds, the 4-piece Noblesse Oblige set is ideal. It increases her Elemental Burst damage and provides an attack boost to the entire team after using her Burst. For sub-DPS builds, the 4-piece Deepwood Memories set is highly recommended. It reduces Dendro resistance of enemies, amplifying the damage of Dendro-based reactions. Alternatively, a 2-piece combination of Deepwood Memories and Gilded Dreams can be used to boost both Dendro damage and Elemental Mastery.

When building Collei, prioritize energy recharge, Elemental Mastery, and Dendro damage bonus. For support builds, aim for at least 180-200% energy recharge to ensure her Burst is always available. For sub-DPS builds, focus on Elemental Mastery and critical stats to maximize reaction damage. Avoid neglecting her energy recharge entirely, as her Burst is a key part of her kit.

Team composition is another critical factor. Collei excels in teams that utilize Dendro reactions. Pair her with Electro characters like Fischl or Yae Miko for Aggravate teams, or Hydro characters like Xingqiu or Kokomi for Bloom teams. In Aggravate teams, her Dendro application triggers the reaction, while in Bloom teams, she enables the creation of Dendro cores. Adding an Anemo character like Kazuha or Sucrose can further amplify reaction damage by grouping enemies and shredding resistances.

Common mistakes to avoid include using Collei as a main DPS, as her kit is not optimized for sustained damage. Additionally, neglecting her energy recharge can lead to inconsistent Burst uptime, reducing her effectiveness. Always ensure her artifacts and weapons align with her role in the team.

Advanced techniques involve timing her Elemental Skill and Burst to maximize Dendro application. For example, in Aggravate teams, use her Skill immediately before switching to an Electro character to trigger the reaction. In Bloom teams, coordinate her Burst with Hydro application to create multiple Dendro cores.

In summary, the best weapon for Collei depends on her role. Favonius Warbow and Sacrificial Bow are ideal for support, while The Stringless and Windblume Ode are better for sub-DPS. Pair her with artifacts like Noblesse Oblige or Deepwood Memories, and build her with energy recharge, Elemental Mastery, and Dendro damage in mind. By optimizing her weapon, artifacts, and team composition, Collei can become a valuable asset in Dendro-focused teams.
