Collei is a four-star dendro character who wields a bow. She predominantly excels in a sub-DPS or reaction driver role, where she applies dendro to enemies with her wide-reaching elemental burst and elemental skill, setting up devastating elemental reactions for your other characters.

Collei’s best weapon is the five-star bow, Polar Star. In terms of artifacts, we recommend a full set of Deepwood Memories, and you should generally focus on boosting her energy recharge, attack, and crit. For more in-depth recommendations and alternates, check out each of the dedicated sections below.

When leveling up her talents, we recommend prioritizing her elemental burst, then her elemental skill, and finally her normal attack.

With decent personal damage, affordable weapon options, and flexibility with both artifacts and team compositions, she makes a great secondary dendro character for many dendro reaction-focused teams. However, she’s pretty energy hungry, and relies on both her constellations and a well-invested team mates to really shine.

How to use Collei

Collei synergises well with dendro DPS such as Genshin Impact’s Tighnari, as you can equip her with Deepwood Memories in order to buff their dendro damage, while also enjoying the benefits of dendro resonance, Sprawling Greenery. The dendro resonance buff increases your party’s elemental mastery by 50 across the board, pushing it even higher when you trigger dendro elemental reactions.

Generally, her normal attacks aren’t worthwhile – it’s her skill and burst that you need to focus on.

Collei’s boomerang (the floral ring from her skill) is the trickiest part of her kit to master, but it’s also the key to a successful Collei player. It applies dendro once when you throw it out, and a second time when it returns, and has a pretty long cooldown of 12 seconds. Luckily, the throw and return applications space out Collei’s dendro application, allowing for a less front-loaded kit which, in turn, compliments quicken teams that require prolonged dendro application.

Unfortunately, due to its long animation, it can be surprisingly easy to hit enemies with Collei’s boomerang at a range, especially with faster enemies that move about a lot. The best way to ensure her boomerang hits both ways is to throw it when she’s close to the enemy, then keep an eye on the boomerang’s arc and move to the left or right of the enemy depending on its trajectory.

Luckily, her elemental burst is a lot easier to pull off – and it also happens to provide the majority of her damage. It has a 15-second cooldown which is only slightly longer than her skill’s cooldown, making her a great option for quickswap teams with rotations of between 15 and 20 seconds.

Unfortunately, the dendro application rate of her burst only ticks three to four times per rotation, but, when combined with her skill and the right team, she can still help keep dendro application at a high up-time.

What’s Collei’s best weapon?

When picking a weapon for Collei, her best five-star options are currently Polar Star and Aqua Simulacra, due to their high base stats and useful damage boosts.

If you’re looking for a four-star option, Favonius Warbow is the best choice due to its great energy recharge and elemental particle generation

Weapon Effect How to obtain
Polar Star Bonus effect: +crit rate%
Skill: 
increases elemental skill and elemental burst damage by 12%. After a normal attack, charged attack, elemental skill, or elemental burst hits an enemy, gain one stack of Ashen Nightstar for 12 seconds. When 1/2/3/4 stacks of Ashen Nightstar are present, attack increases by 10/20/30/48%
Gacha
Aqua Simulacra Bonus effect: +crit damage%

Gacha
Favonius Warbow Bonus effect: +energy recharge%
Skill: crit hits have a 60% chance to generate a small amount of elemental particles, which regenerate six energy for the character. Can only occur once every 12 seconds.

What are Collei’s best artifacts?

If no one else on the team is holding Deepwood Memories, it’s a great idea to give that one to Collei. Aside from that, Emblem of Severed Fate is a good choice for maximizing her elemental bust damage.

Artifacts Effect How to obtain
Deepwood Memories Two equipped: increases dendro damage bonus by 15%
Four equipped: after elemental skills or bursts hit opponents, the targets’ dendro resistance is decreased by 30% for eight seconds. This effect can trigger even if the equipping character is not on the field
Spire of Solitary Enlightenment domain, near Gandha Hill in Sumeru
Emblem of Severed Fate Two equipped: increases energy recharge by 20%
Four equipped:
 increases elemental burst damage by 25% of energy recharge. A maximum of 75% bonus damage can be obtained this way
Momiji-Dyed Court domain, Inazuma

Stat and sub-stat recommendations

Energy recharge is very important to Collei to ensure she can make the most of her burst’s dendro application. Getting that to the desired amount should be your top priority, after which you can boost her other stats.

Elemental mastery is useful to her, but not as integral as it is for Tighnari – and therefore should only be prioritized if you’re running with an elemental reaction focused build.

Main stats

  • Sands: energy recharge (can use attack% or elemental mastery if requirements are met)
  • Goblet: dendro damage bonus
  • Circlet: crit damage/crit rate (try to maintain a 2:1 ratio)

Sub-stats

  • Energy recharge
  • Attack%
  • Crit damage/crit rate
  • Elemental mastery

What are the best Collei team comps?

As you’d expect, Collei shines the brightest in teams that rely heavily on dendro-focused elemental reactions. She fits well in quicken, burgeon, bloom, and hyperbloom teams, especially when supporting a strong, on-field DPS or in 12-20 second rotation quickswap teams.

As mentioned at the beginning of this guide, Collei also benefits greatly from having a second dendro character on the team where possible, as this helps pick up the small gaps between her dendro application, and allows for the elemental mastery buff from dendro resonance.

Here are all of Collei’s abilities and attacks.

Active skills:

Skill Effect
Normal attack: Supplicant’s Bowmanship Normal: perform up to four consecutive shots with a bow
Charged: perform a more precise aimed shot with increased damage. While aiming, dendro energy accumulates around the arrowhead. A fully charged arrow deals dendro damage
Plunge: fire a shower of arrows mid-air before falling and striking the ground, dealing AoE
Elemental skill: Floral Brush Throw out a floral ring that deals one instance of dendro damage to targets it comes into contact with. The floral ring returns after a set time, dealing dendro damage again
Elemental burst: Trump-Card Kitty Throw Collei’s Cuilein-Anbar doll, causing an explosion that deals AoE dendro damage and creating a Cuilein-Anbar zone. Cuilein-Anbar bounces around within this zone, dealing AoE dendro damage

Passive skills: 

Skill Effect
Gliding Champion of Sumeru Decreases gliding stamina consumption for your own party members by 20%. Not stackable with passive talents that provide the same effects
Floral Sidewinder If one of your party members triggers burning, quicken, aggravate, spread, bloom, hyperbloom, or burgeon reactions before floral ring returns, it grants the sprout effect upon return, which continously deals dendro damage equivalent to 40% of Collei’s attack to nearby opponents for three seconds. If another sprout effect triggers during its initial duration, the initial effect is removed. Damage dealt by sprout counts as elemental damage
The Languid Wood When a character within the Cuilein-Anbar Zone triggers burning, quicken, aggravate, spread, bloom, hyperbloom, or burgeon reactions, the zone’s duration increases by one second. A single Trump-Card Kitty can extend by up to three seconds

What are Collei’s constellations?

Gaining more than one copy of a character in Genshin Impact allows you to unlock special bonuses called ‘constellations’. Here are each of Collei’s constellations.

Constellation Effect
C1: Deepwood Patrol When in the party and not on the field, Collei’s energy recharge rate increases by 20%
C2: Through Hill and Copse Reworks Collei’s passive talent Floral Sidewinder with these effects: Floral Ring grants the character the sprout effect from Floral Sidewinder upon return, dealing 40% of Collei’s attack as dendro damage to nearby opponents for three seconds. From the moment of using Floral Brush to the moment when this instance of sprout’s effects end, if any of your party members trigger burning, quicken, aggravate, spread, bloom, hyperbloom, or burgeon reactions, the sprout effect extends by three seconds. It can only be extended this way once. If it triggers again during its initial duration, the initial effect is removed. Requires you to have unlocked the Floral Sidewinder talent
C3: Scent of Summer Increases the level of Floral Brush by three. Maximum upgrade level is 15
C4: Gift of the woods Using Trump-Card Kitty increases all nearby characters’ elemental mastery by 60 for 12 seconds (not including Collei herself)
