Collei build guide · GenGuru: Your guru for Genshin Impact

Overview

Off-field Dendro application
Dendro support

Collei is a 4-star Dendro support who works best off the field. Her Elemental Skill throws a ring that hits enemies on the way out and again on the way back, and her Elemental Burst drops Cuilein-Anbar into a zone where he bounces around dealing Dendro damage for several seconds. If a party member inside the zone triggers a Dendro reaction, the zone lasts a little longer.

She is a reliable way to bring Dendro into Hyperbloom, Aggravate or Spread teams if you do not have a 5-star Dendro character. Give her Energy Recharge so her burst is up every rotation, then ATK, a Dendro goblet and crits. Her four-piece Deepwood Memories set lowers enemy Dendro RES for the whole team, which is often her most valuable contribution.

Weapons

Best first. Every bow on this list links to its page.

Elegy for the End ★★★★★
Gives Energy Recharge and a team-wide Elemental Mastery and ATK buff, which helps every reaction team she joins.
Favonius Warbow ★★★★
Her best 4-star for Energy. It generates particles for her own burst and keeps her rotations smooth.
The Stringless ★★★★
Raises Skill and Burst damage, which is all of her off-field damage. Use it when your team already has enough Energy.
Sacrificial Bow ★★★★
Can reset her Skill for an extra cast and extra particles. The Energy Recharge stat also helps her burst.
End of the Line ★★★★
A free fishing bow with Energy Recharge. A fine choice if you have nothing better.

Artifact sets

Deepwood Memories 4-piece
The main pick. Her Skill and Burst hit often from off the field, so enemies keep their Dendro RES lowered for the whole team.
Noblesse Oblige 4-piece
Use this if someone else already wears Deepwood Memories. It gives the whole party ATK after her burst.
Instructor 4-piece
A cheap reaction set that shares Elemental Mastery with the party, useful in Hyperbloom teams.

Collei applies Dendro off the field so Keqing and Fischl can Aggravate. Kazuha groups enemies and boosts Electro damage.

Tips

Throw her Elemental Skill, swap out right away, and let the ring return on its own.
Her burst zone lasts longer when the party triggers Dendro reactions inside it, so cast it where your damage dealer is fighting.
If she wears Deepwood Memories, no other party member needs it. The RES reduction does not stack.

Talents

Normal Attack Supplicant's Bowmanship

Normal Attack Performs up to 4 consecutive shots with a bow. Charged Attack Performs a more precise Aimed Shot with increased DMG. While aiming, Dendro energy will accumulate on the arrowhead. A fully charged arrow will deal Dendro DMG. Plunging Attack Fires off a shower of arrows in mid-air before falling and striking the ground, dealing AoE DMG upon impact.

Elemental Skill Floral Brush

Throws out a Floral Ring that deals 1 instance of Dendro DMG to targets it comes into contact with. The Floral Ring will return after a set time, dealing Dendro DMG once again.

Elemental Burst Trump-Card Kitty

Trusty Cuilein-Anbar comes to save the day! Throws the doll named Cuilein-Anbar, causing an explosion that deals AoE Dendro DMG, creating a Cuilein-Anbar Zone. Cuilein-Anbar will bounce around within this zone, dealing AoE Dendro DMG.

Passive talent Floral Sidewinder

If one of your party members has triggered Burning, Quicken, Aggravate, Spread, Bloom, Hyperbloom, Burgeon, or Lunar-Bloom reactions before the Floral Ring returns, it will grant the character the Sprout effect upon return, which will continuously deal Dendro DMG equivalent to 40% of Collei's ATK to nearby opponents for 3s. If another Sprout effect is triggered during its initial duration, the initial effect will be removed. DMG dealt by Sprout is considered Elemental Skill DMG.

Passive talent The Languid Wood

When a character within the Cuilein-Anbar Zone triggers Burning, Quicken, Aggravate, Spread, Bloom, Hyperbloom, Burgeon, or Lunar-Bloom reactions, the Zone's duration will be increased by 1s. A single Trump-Card Kitty can be extended this way by up to 3s.

Passive talent Gliding Champion of Sumeru

Decreases gliding Stamina consumption for your own party members by 20%. Not stackable with Passive Talents that provide the exact same effects.

Constellations

C1 Deepwood Patrol

When in the party and not on the field, Collei's Energy Recharge is increased by 20%.

C2 Through Hill and Copse

The Ascension Talent Floral Sidewinder is changed to this: The Floral Ring will grant the character the Sprout effect from Floral Sidewinder upon return, dealing 40% of Collei's ATK as Dendro DMG to nearby opponents for 3s. From the moment of using Floral Brush to the moment when this instance of Sprout effect ends, if any of your party members triggers Burning, Quicken, Aggravate, Spread, Bloom, Hyperbloom, Lunar-Bloom, or Burgeon reactions, the Sprout effect will be extended by 3s. The Sprout effect can only be extended this way once. If another Sprout effect is triggered during its initial duration, the initial effect will be removed. DMG dealt by Sprout is considered Elemental Skill DMG. You must first unlock the Ascension Talent "Floral Sidewinder."

C3 Scent of Summer

Increases the Level of Floral Brush by 3. Maximum upgrade level is 15.

C4 Gift of the Woods

Using Trump-Card Kitty will increase all nearby characters' Elemental Mastery by 60 for 12s (not including Collei herself).

C5 All Embers

Increases the Level of Trump-Card Kitty by 3. Maximum upgrade level is 15.

C6 Forest of Falling Arrows

When the Floral Ring hits, it will create a miniature Cuilein-Anbar that will deal 200% of Collei's ATK as Dendro DMG. Each Floral Brush can only create one such miniature Cuilein-Anbar.
