Rarity	★★★★ (4-Star)
Element	Dendro
Weapon	Bow
Role	Off-field Support / Burst Support
Priority	ER > CRIT > EM > ATK
Tier	A- (Nilou Bloom Specialist)

Collei is a Trainee Forest Ranger active in Avidya Forest. As one of the first Dendro characters released, she offers valuable off-field Dendro application. While her Burst duration is short, her front-loaded application is exceptional, making her a top pick for speed-clearing in Nilou Bloom teams.

Pros

Front-loaded App: Applies a lot of Dendro very quickly (Skill + Burst + Passive), ideal for starting Bloom cores.
Free Unit: Obtained for free from Spiral Abyss Floor 4.
C4 Buffer: Provides 60 EM to the team effortlessly.
No "Circle Impact" issues on Skill (Boomerang follows you).
Shorter animation times than Dendro Traveler.

Cons

Short Duration: Burst only lasts 6s (9s with C2 "Sprout"). Requires frequent swapping.
Small Radius: Burst area is smaller than DMC or Nahida.
ICD Issues: Burst has standard ICD, meaning not every hit applies Dendro.

Quick Guide (TL;DR)

The Goal: Stack ER to burst off-cooldown. Use Skill, wait for "Sprout" (C2), then Burst.

Best Artifact: 4pc Deepwood Memories (Support/Res Shred).
Alt Artifact: 4pc Instructor (EM Buff) or 4pc Emblem (Personal Dmg).
Best Weapon: Elegy for the End (Massive Team Buff).
Alt Weapon: Sacrificial Bow (Reset skill for more energy/dendro).
F2P Weapon: Favonius Warbow (Team Battery).
Main Stats: ER% / Dendro DMG / CRIT.
Talent Priority: Elemental Burst > Elemental Skill > Normal Attack (Ignore).

Pro Tip: The Sprout Mechanic: At C2, Collei's skill creates a "Sprout" (spinning ring) that deals Dendro DMG around the active character. To extend this duration to the max 3s, you must trigger a Dendro reaction before the boomerang returns.

Ascension & Talent Materials

Category	Material Name	Source
Ascension	Rukkhashava Mushrooms	Sumeru Rainforest (Mawtiyima Forest)
Boss Drop	Majestic Hooked Beak	Jadeplume Terrorshroom
Talents	Teachings of Praxis	Steeple of Ignorance (Wed/Sat)
Mob Drop	Firm Arrowhead	Hilichurl Archers

Talent Mechanics

Elemental Skill: Floral Brush

Boomerang: Throws a Floral Ring that deals Dendro DMG on the way out and back.
Floral Sidewinder (A1): If a reaction occurs before the ring returns, it creates a "Sprout" effect dealing continuous Dendro DMG around the active character (scaling with ATK).
Note: Has no vertical hitbox, can miss enemies on different elevations.

Elemental Burst: Trump-Card Kitty

Cuilein-Anbar: Throws a doll that creates a Zone.
Explosion: Deals AoE Dendro DMG on landing, then continuous ticks within the zone.
Duration: 6 seconds (9 seconds with A4 passive). Fast ticks make it great for shield breaking.

Important Passives

A4: The Languid Wood: Triggering reactions inside the Burst zone extends its duration by 1s (max +3s). This is critical for uptime.

Constellation Value

Constellation	Value	Effect
C2: Through Hill and Copse	Core QoL	Changes the "Sprout" mechanics so you always get the effect upon return, and extending it by 3s if a reaction happens. Drastically improves Dendro application consistency.
C4: Gift of the Woods	Support	Using Burst grants 60 EM to all nearby party members (excluding Collei) for 12s. Simple, effective buff.
C6: Forest of Falling Arrows	Damage	When the Boomerang hits, it creates a miniature Cuilein-Anbar that deals 200% ATK as Dendro DMG. Adds a nice burst of extra application.

Verdict: C2 is her most important constellation for smooth gameplay. C4 and C6 are nice bonuses.

Stat Requirements

Stat	Goal
Energy Recharge	160% - 200% (Depends on weapon/team)
Crit Rate	50-60% (For Favonius or personal dmg)
Elemental Mastery	100+ (Secondary stat)

Artifact Main Stats:

Sands: ER% (Recommended) or ATK% / EM
Goblet: Dendro DMG Bonus
Circlet: CRIT Rate / CRIT DMG

Artifacts Comparison

Set	Use Case	Reasoning
4pc Deepwood Memories	Best Support	Mandatory if she is the primary Dendro support to shred 30% RES. Even in double Dendro, she is often the best holder of this set.
4pc Instructor	Buffer	Provides 120 EM to the team. Excellent for Quicken/Aggravate teams where her personal damage matters less than buffing the carry.
4pc Emblem / 4pc Gilded	Sub-DPS	Use these if someone else holds Deepwood (e.g., Zhongli or Kokomi). Increases her personal damage contribution.

Weapon Rankings

Weapon	Rank	Notes
Elegy for the End	S+	Massive team buff (EM + ATK%). Collei triggers it easily with her Burst. Best in slot for support.
Sacrificial Bow	S	Allows double E cast. This generates double particles and applies more Dendro. High base ATK is a bonus.
Favonius Warbow	A	Standard battery option. Good for energy-hungry teams (e.g., with Cyno or Xiangling).
The Stringless	A (DPS)	Best for personal damage due to Skill/Burst DMG bonus and EM substat.

Teams

Nilou Bloom (Speedrun)

Nilou (Bountiful Cores)
Collei (Front-load Dendro App)
Nahida / Dendro MC (Sustained Dendro)
Kokomi / Barbara (Hydro Trigger/Heal)

Collei is preferred over DMC here for faster rotations and burst application.

Aggravate Support

Keqing / Cyno (Main DPS)
Fischl (Sub-DPS)
Collei (Deepwood/Instructor Holder)
Kazuha / Zhongli (Flex)

Collei provides the Quicken aura and buffs without taking field time.

Rotation

Standard Support:
Collei E > Collei Q > Swap

Note: Cast E before Q to catch particles. If using Sacrificial Bow: E > Q > E allows for extremely high Dendro application in a short window.

FAQ

Collei vs Dendro Traveler?
Traveler has better sustained application (longer burst) and larger AoE. Collei has better "burst" application (faster hits in shorter time) and fits 15s rotations better. Collei is often preferred in Nilou teams; DMC in Hyperbloom.

Is C2 Sprout important?
Yes. Without C2, her Dendro application from skill is just one hit. C2 adds the "Sprout" ring which applies Dendro continuously around the active character, making her much better for melee DPS like Cyno or Nilou.
