Genshin Impact Collei Guide

Genshin Impact Collei Guide: Introduction

Collei is a 4-star Dendro Bow character from Sumeru and holds the distinction of being the first 4-star Dendro character in Genshin Impact. She is most valued for her role as an off-field sub-DPS and Dendro support, enabling powerful Dendro-based reactions like Quicken and Aggravate. Her Elemental Skill and Elemental Burst are essential to her kit, as they allow her to apply Dendro to enemies effectively while off the field. Her playstyle revolves around quick-swapping, where players use her abilities and switch to another character for the main damage output.

Though Collei can be built as a main DPS, her damage potential is lower compared to other characters, making her better suited for supporting roles in teams focused on reactions. For those looking to increase her sub-DPS output, investing in her talents and artifacts can significantly boost her utility in combat.

Genshin Impact Collei Guide: Why play Collei?

Collei, a 4-star Dendro Bow character from Sumeru, is highly regarded for her ability to serve as a Dendro support and off-field damage dealer. She excels at applying Dendro consistently through her Elemental Skill and Burst, making her a key enabler of Dendro-based reactions like Quicken, Bloom, and Burning. While not primarily built for damage, Collei can still contribute respectable offense with the right investment.

Her flexible build options, such as the use of F2P weapons like the Favonius Warbow, make her an accessible and useful character for many players, especially those looking to strengthen their Dendro teams. Collei can also utilize a range of artifact sets, including Deepwood Memories and Gilded Dreams, depending on her role within the team. Her Elemental Skill and Burst cooldowns provide ample opportunity for quick rotations, allowing her to fit smoothly into many team compositions. However, Collei does come with her challenges.

She requires significant Energy Recharge to consistently use her Elemental Burst and relies on Constellations, particularly C2, C5, and C6, to unlock her full potential. Despite these limitations, Collei remains an excellent option for players seeking a Dendro support, especially in Burgeon and Burning teams, and a valuable addition to Dendro-based team comps.

Genshin Impact Collei Guide: Talents

Collei’s talents are centered around her role as a versatile Dendro applicator and support character. Her Normal Attacks involve up to four shots with a bow, although these are secondary unless building a Physical DPS variant. The highlight of her abilities is her Elemental Skill, Floral Brush, which throws a ring that applies Dendro DMG and generates Dendro particles, aiding in energy regeneration. Her Elemental Burst, Trump-Card Kitty, summons a doll that continuously applies Dendro DMG in a set area, creating synergy with reactions like Bloom or Hyperbloom.

The Floral Sidewinder passive extends her skill’s effect by dealing additional Dendro DMG to nearby enemies based on reactions triggered before the ring returns, while The Languid Wood extends the Burst’s duration when a reaction occurs inside the Cuilein-Anbar field. Additionally, Gliding Champion of Sumeru provides a 20% reduction in stamina consumption for all party members while gliding. These abilities and passives ensure that Collei excels at applying Dendro to trigger reactions and offers consistent support in teams.

Genshin Impact Collei Guide: Constellations

Collei’s Constellations offer substantial improvements to both her damage and support potential, with each Constellation enhancing different aspects of her kit.

Provides a 20% Energy Recharge bonus when Collei is off the field, making her more efficient in particle generation for the team. While this Constellation isn’t a game-changer, it can help reduce her Energy Recharge requirements.

Enhances the Floral Sidewinder passive by extending the duration of the Sprout effect triggered by certain Elemental reactions. This extension allows Collei to apply Dendro damage more consistently, increasing her overall reaction uptime, though it can only occur once per skill activation. This Constellation is particularly beneficial for Dendro-based reaction teams, where continuous Dendro application is crucial.

Increases the level of her Elemental Skill, Floral Brush, by 3, improving her Dendro application and enhancing her overall usefulness in teams relying on consistent elemental damage.

Grants an Elemental Mastery buff of 60 for all nearby characters when Collei’s Elemental Burst, Trump-Card Kitty, is activated. This buff lasts for 12 seconds, which is ideal for reaction-based teams as it boosts the damage of reactions triggered by those characters. Given her Burst has a 15-second cooldown, this buff is often active during most rotations.

Increases the level of her Elemental Burst, Trump-Card Kitty, by 3, enhancing its effectiveness and further improving her off-field Dendro application. This Constellation is important for maximizing her support role in teams.

Causes Floral Brush to spawn a miniature Cuilein-Anbar each time it hits an enemy, dealing 200% of Collei’s ATK as Dendro damage. While this provides an additional instance of Dendro damage, its significance is diminished due to the timing of the Floral Brush hits. Since the additional Dendro application occurs when the skill returns, it overlaps with the primary hit, resulting in only marginally increased damage.

Overall, C2 and C4 are Collei’s most important Constellations for enhancing her support capabilities, particularly in reaction-based teams. C6 provides an additional damage boost but isn’t as vital for her overall playstyle.

Genshin Impact Collei Guide: Builds

Collei in Genshin Impact is an adaptable Dendro Bow user, whose build can be customized to fit both damage-dealing and support roles. Depending on her function in the team, players may opt for different Artifacts and weapons to maximize her utility. For support-focused builds, Deepwood Memories is an excellent 4-piece set, boosting Dendro damage and applying Dendro RES reduction to enemies, which is ideal for enhancing reactions like Quicken, Burning, and Bloom.

Gilded Dreams shines in builds emphasizing Elemental Mastery (EM), especially in teams where Collei’s teammates are non-Dendro characters. Alternatively, Noblesse Oblige is great for support in teams relying on Burning, providing a team-wide ATK boost that works well when paired with Collei’s Elemental Burst. Tenacity of the Millelith offers another support option, enhancing Collei’s damage as it works well with her Sprout effects from her Elemental Skill. If focusing on Elemental Mastery, Instructor boosts her EM, enhancing reactions, and The Exile is a niche choice for teams needing energy regeneration.

When selecting Main Stats, prioritize Energy Recharge (ER), Elemental Mastery (EM), or ATK% on the Sands depending on Collei’s Energy needs and the team’s requirements. The Goblet should focus on Dendro DMG Bonus, enhancing her elemental abilities. For the Circlet, choose CRIT Rate or CRIT DMG, as they help maximize her damage potential in reaction-heavy teams. Substat priorities should be Energy Recharge, CRIT Rate, CRIT DMG, and Elemental Mastery, ensuring that Collei can trigger her Elemental Burst consistently while maximizing her contribution to elemental reactions.

For Weapons, Collei can benefit from Energy Recharge options like the Favonius Warbow, which generates extra particles to help the entire team’s energy management. The Sacrificial Bow is another excellent choice for Collei as it allows her to trigger her Elemental Skill more often, enhancing Dendro application with multiple hits per rotation. Elegy for the End is a 5-star weapon that provides significant buffs, offering Elemental Mastery, Energy Recharge, and ATK%, making it an excellent option for Collei’s EM-focused builds. Fading Twilight, a newer event weapon, is also a great choice with offensive passives and Energy Recharge sub-stats.

For DPS builds, while Collei is not primarily a damage dealer, she can still work well with weapons that increase Elemental Skill/Burst damage, such as The Stringless, which provides a boost to her Elemental abilities, or Aqua Simulacra, which increases CRIT Rate and CRIT DMG. Polar Star is another potent option that increases overall damage potential through stacking ATK%. Alley Hunter works well for swap-based playstyles, providing a damage bonus when Collei is not on the field but active in combat.

For an Elemental Mastery (EM) build, focus on increasing Collei’s ability to trigger strong reactions like Bloom, Burning, and Aggravate. In this setup, her Artifacts should prioritize Energy Recharge (until it’s at a sufficient level) and Elemental Mastery. For the Sands, choose ER% or EM, while the Goblet and Circlet should both focus on EM. Weapons like Elegy for the End, Sacrificial Bow, or The Stringless synergize well with this build, enhancing her reaction damage potential. Substats should prioritize Energy Recharge until the ER needs are met, then shift to EM to maximize reaction damage.

This comprehensive build approach allows Collei to be a potent support or reaction trigger, providing consistent off-field Dendro application and boosting the team’s overall elemental synergy.

Genshin Impact Collei Guide: Teams

Collei is a flexible character who can excel in a variety of team compositions centered around Dendro reactions. When building a team around her, focus on the intended reaction type, ensuring that teammates complement Collei’s abilities. In Quicken/Aggravate/Spread teams, Collei is highly effective as an off-field Dendro applicator or battery. Her Dendro abilities are especially valuable when paired with Electro units like Fischl, Keqing, Raiden Shogun, or Yae Miko, as they can trigger Aggravate or Spread reactions. In these teams, double Electro or double Dendro setups are often used, with an Anemo character or Zhongli filling the remaining slot for either crowd control or defense.

For Bloom/Hyperbloom/Burgeon teams, Collei can support by applying Dendro to trigger Transformative Reactions like Hyperbloom and Burgeon. These teams rely on Hydro characters, such as Yelan, Xingqiu, or Kokomi, to apply Hydro and enable consistent Dendro Core generation. In Hyperbloom-focused setups, pairing Collei with Electro units like Kuki Shinobu can enhance the Hyperbloom reactions. For Burgeon, Pyro characters like Thoma can be used to deal significant damage when Dendro Cores explode. Anemo characters, such as Kaedehara Kazuha or Sucrose, can be included for additional elemental swirl and crowd control.

Bloom/Fridge teams incorporate a Cryo character to create Freeze reactions, which reduce the depletion of Elemental Auras, allowing for more reaction opportunities. These teams benefit from reduced Dendro resistance, ensuring that Transformative Reactions, such as Bloom, are triggered more efficiently. Characters like Kamisato Ayaka, Ganyu, Rosaria, or Kaeya can be used for Cryo application, while Hydro characters such as Yelan or Xingqiu help generate Dendro Cores.

For Burning teams, Collei excels in off-field Dendro application, which is crucial for keeping the Burning effect active when paired with Pyro characters like Amber, Xiangling, Thoma, or Bennett. These teams focus on consistently applying Dendro to trigger Damage over Time effects from the Burning reaction, with Collei playing a central role in maintaining Dendro application.

Although Collei’s primary focus is not Physical damage, she can be integrated into Physical teams where her Dendro application helps trigger reactions like Superconduct, reducing enemy physical resistance. To maximize damage in this role, Collei should be supported by high damage-dealing characters, such as Fischl, Rosaria, or Bennett, who can take advantage of the lowered physical resistance.

Collei’s versatility makes her an invaluable asset in teams designed around Dendro reactions, and her ability to generate Energy particles and apply Dendro off-field allows her to enhance the capabilities of many different team setups.

Genshin Impact Collei Guide: Playstyle and Rotations

Collei is primarily a Dendro support character, with her role focusing on enabling Dendro reactions and providing consistent off-field Dendro application. As a quick-swap sub-DPS, Collei’s playstyle involves casting her Elemental Skill and Burst and then swapping out to other characters for optimal reaction setups. To maximize her effectiveness, prioritize leveling her Elemental Skill and Elemental Burst, as her Normal Attack is rarely used unless you are building a physical DPS version of Collei.

Her Elemental Skill, Floral Brush, is a quick, boomerang-like attack that deals Dendro damage on both the throw and return, while generating three Dendro particles to help with energy regeneration. There is no ICD on her skill hits, which allows it to trigger multiple reactions in rapid succession. Collei’s Elemental Burst, Trump-Card Kitty, creates an AoE field that deals continuous Dendro damage, applying Dendro up to three times per enemy during its duration. Although its application is somewhat limited, it provides a steady Dendro uptime, especially when combined with other Dendro reactions.

In terms of rotations, Collei typically uses her Elemental Skill, followed by her Elemental Burst before swapping to another character. For optimal Dendro application, use her Elemental Skill just before and immediately after her Burst. Since Collei’s Burst has a cooldown, focus on building Energy Recharge (ER) to use her Burst consistently. High ER is important for her medium-energy requirements, and using weapons like the Sacrificial Bow, which reduces cooldown, can provide flexibility in rotations and help maintain Burst uptime.

For team rotations, in Quicken teams, Collei serves as a reliable Dendro unit, especially when paired with Electro characters. Since Quicken triggers naturally last a longer time, less frequent Dendro application may be needed in these teams. In Bloom/Hyperbloom/Burgeon teams, Collei primarily functions as an off-field Dendro applier, leaving the space for Hydro, Electro, and Anemo characters to trigger reactions. Be mindful of her Burst’s limited Dendro application (three instances max) and its duration.

Collei’s A1 passive further enhances her utility, as it grants the Sprout effect to any character who triggers a Dendro-related reaction before the Floral Ring returns, boosting team synergy. This is particularly useful if her Elemental Skill is cast when an enemy already has a reactable aura. As for her constellations, C1 can help alleviate Energy Recharge issues, but its effectiveness is limited because off-field particles only generate a fraction of the full energy. C2 adds another instance of Dendro application to her Burst, increasing her overall utility in reaction-heavy teams.

Genshin Impact Collei Guide: Advanced

To maximize Collei’s potential, it’s important to consider her constellations, weapons, artifact sets, and optimal team compositions. Her C1 (Deepwood Patrol) reduces her energy recharge (ER) needs by 15% on the field and increases her ER by 20% off-field, although off-field ER benefits are less effective due to the reduced energy value of off-field particles. C2 (Through Hill and Copse) extends the duration of her A1 passive, granting more Dendro application by increasing Sprout’s duration by 3 seconds.

C4 (Gift of the Woods) boosts the Elemental Mastery of all nearby characters by 60 for 12 seconds when Collei’s Burst is used. C6 (Forest of Falling Arrows) creates a miniature Cuilein-Anbar when the Floral Ring hits, providing additional Dendro damage for extra Dendro applications.

For weapons, Energy Recharge (ER) weapons like Elegy for the End, Sacrificial Bow, and Favonius Warbow help Collei manage her ER requirements. Elegy for the End boosts Elemental Mastery, ER, and ATK%, which benefits Collei’s support role. Sacrificial Bow is perfect for enabling higher Dendro application with multiple hits of her Elemental Skill. Favonius Warbow reduces the entire team’s ER needs, though it requires Collei to have at least 30% Crit Rate to trigger its passive. Fading Twilight can increase ER and optimize her energy cycle.

For artifact sets, 4-piece Deepwood Memories enhances Dendro reaction damage and reduces Dendro resistance, making it a top choice for Collei if there is no other Deepwood holder on the team. 4-piece Noblesse Oblige is better suited for Quicken and Aggravate teams focused on Electro damage. 4-piece Instructor is a more budget-friendly option, boosting Elemental Mastery for the whole team. 4-piece Gilded Dreams excels at personal damage, especially in Bloom-focused teams. 4-piece Tenacity of the Millelith is effective in Aggravate teams, especially when paired with Collei’s C2 passive, allowing her to consistently hit enemies with Dendro.

For artifact stats, prioritize Energy Recharge on the Sands, Dendro DMG Bonus on the Goblet, and Crit Rate/DMG on the Circlet. Substats should prioritize Energy Recharge, followed by Crit Rate/DMG, ATK%, and Elemental Mastery. Ideally, aim for 200% Energy Recharge to maintain consistent energy flow, though adjustments can be made depending on your team and available Energy generating options.

In team compositions, Collei excels in Electro-based teams, where she acts as a consistent off-field Dendro applicator. She pairs well in Double Electro/Dendro teams or with high-DPS Electro characters to trigger Dendro reactions efficiently. In Burning teams, Dendro application is critical as it fuels the damage output of the Pyro characters involved.

For talent prioritization, focus on leveling her Elemental Skill and Elemental Burst, while her Normal Attack can be left behind unless building a physical DPS version. As a sub-DPS, her weapon should have Crit stats or DMG bonuses focused on her Elemental Skills and Bursts. As a support, you can keep the talent leveling minimal to reduce cost.

Rotation tips include using her Elemental Skill twice within a 24-second window for maximum energy generation. If using Sacrificial Bow, her skill reset can allow greater flexibility in applying Dendro and optimizing her energy cycle. In Aggravate teams, use Tenacity of the Millelith for a strong, near-unlimited uptime on team-wide ATK boosts, maximizing Collei’s synergy in fast-paced rotations.
