The best Genshin Impact Collei build enables this shy forest ranger apprentice to become a hero in no time. Elemental Mastery and Energy Recharge will be the keys to unlocking Collei’s potential as a Sub DPS, who helps the Main DPS trigger devastating reactions. Her kit of abilities is very simple and easy to use, making Collei perfect for testing out Dendro teams.

Her Elemental Skill, Floral Brush, fires off a boomerang imbued with Dendro power. Trump-Card Kitty, her Elemental Burst, unleashes the power of Dendro in an explosive area-of-effect attack, creating a short-lived zone dealing Dendro damage to any enemies within. These skills are very straightforward to use and allow Collei to consistently contribute off-field Dendro effects.

You won’t want to use Collei for her Normal Attacks, as those are rather weak. Her Elemental Skill also has a relatively long cooldown, which isn’t ideal, and her Constellations play a big role in making her Elemental Burst more reliable. Smart timing and a good artifact build definitely help alleviate these weaknesses, though, so be sure to keep reading for the details.

Ready to take some notes on how to build Collei? Then let's go!

Best Collei weapons – Genshin Impact

Collei primarily uses her abilities to contribute damage to the team, so weapons helping to boost this category are high on the priority list. These include Aqua Simulacra, which provides a 20% boost to all damage sources, and Polar Star, which buffs Elemental Skill and Elemental Burst damage by 12%. However, weapons that increase her Elemental Mastery or Energy Recharge are solid choices as well.

Here are the best weapons for Collei in Genshin Impact:

  • Aqua Simulacra (5-star bow)
  • Polar Star (5-star bow)
  • Favonius Warbow (4-star bow)
  • The Stringless (4-star bow)
  • Fading Twilight (4-star bow)

Best Collei artifacts – Genshin Impact

You should choose Collei’s artifact set after clearing up a few other things. If Collei is on your team to support a Dendro Main DPS, then you should definitely equip her with Deepwood Memories. This set provides additional Dendro damage and shreds enemies’ resistance to that element after hitting them with an ability. It’s a fantastic support item for any Dendro team.

If someone else is already carrying Deepwood Memories, a full set of Noblesse Oblige, a classic support set, is a wise choice. For a very reaction-focused team you could also consider Gilded Dreams, which buffs Elemental Mastery up by a lot.

You should get the following stat distribution on Collei’s artifact set:

  • Flower: HP (main stat), Energy Recharge, Elemental Mastery, Critical Hit Rate, Critical Damage (secondary stats)
  • Plume: Attack (main stat), Energy Recharge, Elemental Mastery, Critical Hit Rate, Critical Damage (secondary stats)
  • Sands: Elemental Mastery (main stat), Energy Recharge, Critical Hit Rate, Critical Damage, Attack % (secondary stats)
  • Goblet: Dendro Damage % (main stat), Energy Recharge, Elemental Mastery, Critical Hit Rate, Critical Damage (secondary stats)
  • Circlet: Critical Hit Rate or Critical Damage (main stat), Energy Recharge, Elemental Mastery, Critical Hit Rate or Critical Damage, Attack % (secondary stats)

Best Collei teams – Genshin Impact

Collei is a Sub DPS archetype that fits well with any reaction-based teams that can make use of her excellent off-field Dendro application.

This team based around the Quicken reaction is an example for Collei acting as a Deepwood Memories carrier for the Main DPS, in this case Alhaitham. Fischl and Shinobu contribute the necessary Electro effects, but also act as battery (Fischl) and healer (Shinobu).

You could switch Tighnari in for Alhaitham, Raiden Shogun or Yae Miko for Fischl, and Dori for Shinobu.

Yoimiya is a fantastic Main DPS to pair up with Collei, as the Sub DPS can make up for the Pyro character’s lack of area-of-effect damage. Kokomi is there to spread Hydro effects and heal the party, while Yun Jin buffs up Yoimiya’s Normal Attacks.

Collei works with other Main DPS characters, who are able to use Dendro for their reactions, in the same manner. Examples would include Kamisato Ayato, Tartaglia, and Klee. Naturally, you can switch Bennett, Barbara, or Thoma into the Support slot depending on the Main DPS you field.

Collei ascension materials – Genshin Impact

You’ll want to quickly raise Collei’s level when you finally get her, which means that you’ll need to farm her ascension materials. You’ll also require some material to upgrade her talents.

Here’s what you need to get Collei to level 90:

  • Nagadus Emerald Sliver x1
  • Nagadus Emerald Fragment x9
  • Nagadus Emerald Chunk x9
  • Nagadus Emerald Gemstone x6
  • Firm Arrowhead x18
  • Sharp Arrowhead x30
  • Weathered Arrowhead x36
  • Rukkhashava Mushrooms x168
  • Majestic Hooked Beak x46
  • Mora x2,092,530

The Jadeplume Terrorshroom in Sumeru should be the first thing you farm to upgrade Collei, as it will drop Nagadus Emeralds and Majestic Hooked Beaks for you. Arrowheads are a common material from Hillichurls with crossbows, so you should have hundreds of those stocked up already. Rukkhashava Mushrooms can be found in Sumeru’s Ashavan Realm and Lokapala Jungle. The best way to earn more Mora is to farm golden Ley Line Blossoms.

Here’s what you need to upgrade all of Collei’s talents to their maximum level:

  • Firm Arrowhead x18
  • Sharp Arrowhead x66
  • Weathered Arrowhead x93
  • Teachings of Praxis x9
  • Guide to Praxis x63
  • Philosophies of Praxis x114
  • Tears of the Calamitous God x18
  • Crown of Insight x3
  • Mora x4,957,500

As mentioned above, Arrowheads get dropped by crossbow-Hillichurls. Books of Praxis are available on Wednesday, Saturday, and Sunday from the Steeple of Ignorance Domain in Sumeru.

Tears of the Calamitous God are a boss material obtained from defeating Raiden Shogun under the Grand Narukami Shrine in Inazuma. Crowns of Insight are a rare item gained from time-limited events or regional reward mechanics like the Tree of Dreams in Sumeru or the aforementioned Grand Narukami Shrine.
