Genshin Impact Collei banner, skills, and more

The forest is a dangerous place. Lucky you've got the dendro bow weilding forest ranger-in-training, Genshin Impact's Collei, to help you along the way!

Many of us have been desperately awaiting the arrival of dendro as a playable element, and with  Genshin Impact’s Collei joining the roster, we finally get the chance to channel our inner Poison Ivy. And that’s not the only exciting new change as we take our first steps into the dense foliage of Sumeru – but, luckily, this charming forest ranger-in-training is here to lend a helping hand.

As an introduction to the element, Genshin Impact’s Collei has a pretty simple kit similar to that of Genshin Impact’s Amber, which sounds like a great idea to us – you gotta learn to walk before you start swinging from vines. Of course, a simple kit doesn’t mean that Collei can’t kick some serious butt, so let’s take a look at Genshin Impact Collei’s banner, skills, best weapons and artifacts, and more.

If you want to learn about Collei’s homeland, check out our Genshin Impact Sumeru guide. We’ve also got the deets on other characters from the region, including Genshin Impact’s Tighnari and Genshin Impact’s Dori. Or, for a bit of guidance getting your booty up to scratch as you set out into the forest, check out our Genshin Impact tier list and our Genshin Impact artifacts guides.

Genshin Impact Collei

Who is Genshin Impact’s Collei?

Collei is a four-star dendro bow wielder, and an Avidya forest ranger trainee from Sumeru. She has a similar kit to Genshin Impact’s Amber, and is best suited to a sub-DPS role where she can be used to apply the dendro elements for devastating elemental reactions.

Collei plays a prominent role in the Genshin Impact manga, in which she befriended Amber, before eventually moving to Sumeru. She’s been through a lot of trauma, especially at the hands of the Fatui and the Harbingers, but has since grown into a bright, optimistic, and friendly young woman.

When is Genshin Impact Collei’s banner?

Collei is featured on the first banner of version 3.0 as one of the four-stars alongside Genshin Impact’s Tighnari and Genshin Impact’s Zhongli. You can also snag a free copy of her by taking part in the Graven Innocence event.

Check out our Genshin Impact banner and Genshin Impact events guides to find out more.

What’s the best Genshin Impact Collei build?

Collei is the first four-star dendro character. She predominantly excels in a sub-DPS 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 synergises well with Tighnari as you can equip her with Deepwood Memories in order to buff his dendro damage, while also enjoyed 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.

What are Genshin Impact Collei’s skills?

Here are all of Genshin Impact Collei’s attacks, talents, and skills.

Collei normal attacks

Skill Effect
Supplicant’s Bowmanship (normal attack) Perform up to four consecutive shots with a bow
Supplicant’s Bowmanship (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
Supplicant’s Bowmanship (plunging) Fire a shower of arrows mid-air before falling and striking the ground, dealing AoE damage on impact

Collei elemental skill

Skill Effect
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

Collei elemental burst

Skill Effect
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 vounces around within this zone, dealing AoE dendro damage

Collei passives

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 you the sprout effect upon return, which continuously 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 is considered 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’s the best Genshin Impact Collei 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.

When picking a four-star option, Favonius Warbow is the best choice due to its great energy recharge and elemental particle generation, both of which are important for Collei due to her expensive burst cost.

Weapon Effect How to obtain
Aqua Simulacra Bonus effect: +crit damage%
Skill: increases HP by 16%. When there are opponents nearby, damage increases by 20%. This takes effect whether the character is on-field or not
Gacha
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
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 the best Genshin Impact Collei artifacts?

In order to get the most out of Collei, you should focus on increasing her energy recharge to make up for the high cost of her elemental burst. Getting it to around 170%-200% allows you to use it pretty much whenever it’s off cooldown.

If no one else on the team is holding Deepwood Memories, it’s a great idea to give that one to Collei – especially if you’re putting her alongside her master, Tighnari. Aside from that, Emblem of Severed Fate is a good choice for maximising her elemental bust damage.

Artifacts Effect How to obtain
Deepwood Memories Two equipped: dendro damage bonus +15%
Four equipped: after elemental skills or bursts hit opponents, the targets’ dendro resistance is decreased by 30% for eight seconds. This effect can be triggered 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

Collei artifact stat and sub-stat recommendations

As mentioned above, energy recharge is very important to Collei due to her expensive burst. 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 prioritised 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 Genshin Impact 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)
