Collei is a free 4★ Dendro Bow character obtainable from the Sumeru Archon Quest. She fills an off-field Dendro applicator role in Bloom, Hyperbloom, and Quicken teams. She is largely outclassed by Nahida, Yaoyao, and even Dendro Traveler, but works adequately on a budget. Pull (or use the free copy) if you need a second Dendro unit and lack better options.

With Favonius Warbow

Favonius procs generate neutral particles. 180% ER keeps Cuilein-Anbar cycling consistently.

With Sacrificial Bow

Sacrificial's CD reset allows double Skill cast. Helps generate more Dendro particles.

Solo Dendro, no Favonius

Without particle support, invest heavily in ER substats to maintain Burst every rotation.

~200%+

Collei's Burst is her primary Dendro source. Maintain ~180–200% ER with Favonius Warbow or Sacrificial Bow. At C4+ her Burst matters even more — prioritize uptime.

Collei's Burst summons Cuilein-Anbar which hits off-field, automatically applying -30% Dendro RES without Collei needing to stay on-field. If no Dendro teammate carries Deepwood, Collei must.

4pcWithin 8s of triggering an Elemental Reaction, the character equipping this will obtain buffs based on the Elemental Type of the other party members. ATK is increased by 14% for each party member whose Elemental Type is the same as the equipping character, and Elemental Mastery is increased by 50 for every party member with a different Elemental Type. Each of the aforementioned buffs will count up to 3 characters. This effect can be triggered once every 8s. The character who equips this can still trigger its effects when not on the field.
When another Dendro teammate already carries Deepwood, Gilded Dreams provides EM and ATK based on party elemental diversity — useful in Quicken or Bloom compositions.

Healer

Collei as the second Dendro unit in a Nilou Bloom team. Her off-field Cuilein-Anbar Dendro application contributes Bloom seed generation alongside Nahida's Dendro. Nilou's Bountiful Core passive converts all Blooms into empowered Bountiful Cores.

Character Synergy
Nilou
NilouMain DPS

Bountiful Core passive requires all-Dendro/Hydro party. Collei fills the second Dendro slot perfectly.

Nahida
NahidaDendro Support

Primary Dendro applicator and team EM buffer via A4 passive. Collei supplements Nahida's Dendro application for denser Bloom seed generation.

Collei

Cuilein-Anbar provides supplemental off-field Dendro. Deepwood Memories on Collei reduces enemy Dendro RES by 30%, increasing Bloom seed DMG.

Kokomi

Consistent Hydro for Bloom generation and healing to counter Bountiful Core self-damage. Second Hydro unit for Nilou's party requirement.

Elemental SkillFloral Brush

Collei throws a Floral Ring that deals Dendro DMG and returns to her, hitting enemies along the way. At C6, the ring also deals Dendro DMG on return. Generates 2 Dendro particles per cast.

Dendro DMGDendro ParticleQuick Cooldown
Elemental BurstTrump-Card Kitty

Collei throws Cuilein-Anbar — a cat-shaped boomerang doll — that bounces around the field dealing AoE Dendro DMG to nearby enemies for its duration. Cuilein-Anbar is Collei's primary Dendro application tool; it remains active even when Collei is off-field.

If a party member triggers a Dendro reaction while Collei's Floral Ring is active, the ring's effect is extended by 3 seconds. Rewards teams with active Dendro reactions.

Ascension 4The Languid Wood

When Trump-Card Kitty ends, Collei creates a zone of Sprout petals that deal Dendro DMG every 2 seconds. An extension of Cuilein-Anbar's duration, providing additional Dendro after the doll finishes.

C1An Oath to Flower

Direct damage buff to Trump-Card Kitty's bouncing hits. Minor improvement.

Is it worth getting?

Small QoL. Not a pull target.

C2Lush Pampas

After any elemental reaction, Collei's Sprout state briefly persists, creating more Dendro application opportunities outside the Burst.

Is it worth getting?

Improved Dendro application in reaction-heavy teams. Decent constellation.

C3Chambers of Orogeny

Increases Trump-Card Kitty's DMG and duration.

Is it worth getting?

Incremental.

C4Languid Wood's ResponsePull Target

Each Cuilein-Anbar bounce creates an Explosive Blossom that detonates dealing AoE Dendro DMG. Significantly improves Dendro application frequency and total damage.

Is it worth getting?

The most impactful Collei constellation. C4 noticeably improves her Dendro coverage in multi-target fights. Pull target for Collei investment.

C5A Bough That Shelters All

Increases Floral Brush DMG.

Is it worth getting?

Minor.

C6Ancestral Hymns to All That Grows

Floral Ring bounces twice instead of once, dealing more hits and Dendro applications. Extra particle generation reduces Burst ER requirements.

Is it worth getting?

Solid improvement to her off-field Dendro output and energy efficiency. Good endgame constellation.

C0 is functional but noticeably weaker. Aim for C4 for meaningfully improved Dendro application in Bloom and Hyperbloom teams. First stop: C4.
