Genshin Impact Collei Build Guide

Looking to build Collei, our adventurous Dendro archer from Sumeru? You’ve come to the right place! Collei’s got a lot to offer, whether you’re teaming her up for powerful Dendro reactions or making the most of her support skills. I’ll walk you through all the must-haves—like weapons, artifacts, and team comps—to really get Collei shining in your lineup.

Collei Build Overview

Let’s set the scene: Collei is a Dendro support character who wields a bow and pairs well with a reaction-heavy team. She’s a great fit for Bloom, Hyperbloom, and Aggravate teams, adding that Dendro flair and bringing the energy recharge you need to keep the team going. Plus, she’s got this adorable sidekick, Cuilein-Anbar, who helps her dish out AoE Dendro damage. Ready to dive in?

Collei’s Ascension Materials

Alright, let’s talk materials. You’ll need a good mix of boss drops, region-specific mushrooms, and Hilichurl trophies to get her maxed out. Here’s what’s on the list:

  1. Nagadus Emeralds (Slivers to Gemstones)
    • You’ll be farming the Jadeplume Terrorshroom, which honestly, sounds scarier than it is.
  2. Majestic Hooked Beak
    • Also from our friend the Terrorshroom. So, if you weren’t already, get used to seeing a lot of it.
  3. Rukkhashava Mushrooms
    • Grab these in the forests of Sumeru. They’re pretty easy to find around giant tree trunks—honestly, kind of like finding mushrooms IRL if you know where to look.
  4. Arrowheads (Firm, Sharp, and Weathered)
    • These drop from Hilichurl archers and get used up fast, so plan for a few farming runs to keep your supply steady.

And voilà! With these goodies, Collei will be ready to tackle Teyvat at her peak power.

Collei’s Best Weapons

Choosing the right weapon is where things start getting really interesting. Collei’s all about reactions, so let’s see what weapons work best for her.

  1. Elegy for the End
    • If you’ve got this 5-star, it’s practically made for her. This bow not only gives Collei a boost in Energy Recharge but also buffs the whole team’s Elemental Mastery (EM). In simpler terms? She makes every reaction go “boom!” with this bow.
  2. Polar Star
    • High CRIT Rate, high ATK boost…what’s not to love? If you want Collei dealing some impressive personal damage, this bow will have her landing solid shots.
  3. Sacrificial Bow
    • Here’s a classic for support characters. It gives Energy Recharge and can reset her skill cooldown. It’s perfect for getting that Floral Ring out there more often, meaning more Dendro and more reactions.
  4. Favonius Warbow
    • Want more energy particles for your team? This bow’s got you. It’s especially useful if you’re focusing on rapid Burst uptime, which is where Collei shines.
  5. Aqua Simulacra
    • Big CRIT DMG boost with a splash of ATK. This is more for when you’re trying to pump out some serious numbers, even though Collei is mostly a support character. But hey, nothing wrong with a little damage boost here and there!

Collei’s Best Artifacts

Now onto the real fun: artifacts. Collei’s got several solid options, depending on what you want her to focus on.

  1. Deepwood Memories (4-piece)
    • Collei + Deepwood Memories = Dendro powerhouse. This set gives Dendro DMG bonus and reduces enemy Dendro resistance, so reactions hit even harder. If you’re leaning into reactions, this is pretty much the set.
  2. Noblesse Oblige (4-piece)
    • This one’s all about Elemental Burst damage, plus it buffs the entire team’s ATK for a bit after she uses her Burst. If you’ve got her in a supporting role and want a bit more team synergy, Noblesse is a solid pick.
  3. Tenacity of the Millelith (4-piece)
    • A little unorthodox, but hey, it works! The 4-piece Tenacity set buffs ATK and shield strength, which is great if you’re pairing Collei with a shielder. And since her Floral Brush can trigger it, she keeps that buff up consistently.
  4. Instructor (4-piece)
    • More Elemental Mastery for the whole team? Yes, please. This one is great if you’re all about those juicy reactions—Bloom, Aggravate, and Hyperbloom fans will get a kick out of this.
  5. Gilded Dreams (4-piece)
    • Another EM-boosting set, which adds flexibility depending on team comp. Paired with other elements, Gilded Dreams turns Collei into a reaction powerhouse, giving her either ATK or EM depending on her teammates.

Collei’s Stats and Substats

So, what stats do you actually want to go for? Here’s the breakdown:

  • Sands: Energy Recharge (priority) or ATK%
  • Goblet: Dendro DMG
  • Circlet: CRIT Rate or CRIT DMG

For substats, it’s pretty straightforward:

  1. Energy Recharge – keeps her Elemental Burst ready to go.
  2. CRIT Rate/CRIT DMG – handy for a bit of personal damage.
  3. ATK% – bonus to her overall damage.
  4. Elemental Mastery – boosts reaction damage, which is a huge part of her role.

Collei’s Talents and Playstyle

Collei’s abilities make her a consistent support character, especially if you’re running her in a team that loves Dendro reactions. Let’s break them down a bit.

Normal Attack: Supplicant’s Bowmanship

  • Her normal bow shot is fine, but honestly, you won’t be using this much. It’s there, but it’s not her main thing.

Elemental Skill: Floral Brush

  • Collei throws out a boomerang (well, a Floral Ring) that deals Dendro DMG on the way out and back. It’s like a homing Dendro Frisbee. This is her bread and butter for applying Dendro.

Elemental Burst: Trump-Card Kitty

  • She brings out Cuilein-Anbar, who bounces around dealing AoE Dendro DMG. Not only is this super cute, but it’s also effective for triggering reactions, which is where Collei’s support magic truly shines.

Collei’s Passives

  1. Floral Sidewinder
    • Adds an effect that deals extra Dendro DMG after triggering certain reactions. It’s pretty neat and makes her even better at keeping reactions going.
  2. The Languid Wood
    • Increases her Burst duration each time you trigger certain reactions. Talk about extending the fun!
  3. Gliding Champion of Sumeru
    • Less stamina used when gliding. It’s not going to change your gameplay much, but it’s a nice little bonus. (Not that we’d turn down a little free stamina!)

Collei’s Best Team Compositions

  1. Nilou Bloom Team
    • Nilou (Hydro), Collei (Dendro), Nahida (Dendro), Kokomi (Hydro)
    • Bloom’s the name of the game here. Collei keeps Dendro on the field while Nilou and Kokomi get Hydro going for an endless Bloom cycle. You’ll love how quickly this team mows through enemies.
  2. Keqing Aggravate Team
    • Keqing (Electro), Fischl (Electro), Collei (Dendro), Kazuha (Anemo)
    • If you like your battles flashy, this one’s for you. Collei’s Dendro enables Keqing and Fischl’s Electro skills to deal extra damage. The result? An Aggravate-filled frenzy of electrocuted enemies.
  3. Tighnari Quickswap Team
    • Tighnari (Dendro), Fischl (Electro), Collei (Dendro), Zhongli (Geo)
    • A quick and efficient rotation team with Collei and Tighnari handling Dendro, while Fischl deals Electro damage and Zhongli keeps everyone safe with his shield. It’s efficient, reliable, and honestly pretty fun to play.

Final Thoughts

Collei is a perfect example of how a well-built character can make a huge difference in your Genshin experience. With her balanced Dendro application, great synergy potential, and flexible team comps, she’s worth investing in if you’re looking to explore reaction-heavy strategies. Whether you’re trying out Bloom with Nilou or going full Aggravate with Keqing, Collei can make it work.

Give her the right artifacts, choose a good team comp, and let her go to town. Now, go give Collei the build she deserves! Happy adventuring in Teyvat!
