TC1: Supplicant's Bowmanship

Normal Attack
Performs up to 4 consecutive shots with a bow.

Charged Attack
Performs a more precise Aimed Shot with increased DMG.
While aiming, Dendro energy will accumulate on the arrowhead. A fully charged arrow will deal Dendro DMG.

Plunging Attack

TC2: Floral Brush

Throws out a Floral Ring that deals 1 instance of Dendro DMG to targets it comes into contact with.
The Floral Ring will return after a set time, dealing Dendro DMG once again.

This is Collei's go-to gadget for dealing with unruly wild beasts. A few good thwacks from this tool will generally improve their behavior. This same principle works just as well on evildoers.

TC3: Trump-Card Kitty

Trusty Cuilein-Anbar comes to save the day!
Throws the doll named Cuilein-Anbar, causing an explosion that deals AoE Dendro DMG, creating a Cuilein-Anbar Zone. Cuilein-Anbar will bounce around within this zone, dealing AoE Dendro DMG.

"Pretty impressive, huh? ... Eh? You want to know how I came up with the name Cuilein-Anbar? Uh, well, I..."

TP1: Floral Sidewinder

If one of your party members has triggered Burning, Quicken, Aggravate, Spread, Bloom, Hyperbloom, Burgeon, or Lunar-Bloom reactions before the Floral Ring returns, it will grant the character the Sprout effect upon return, which will continuously deal Dendro DMG equivalent to 40% of Collei's ATK to nearby opponents for 3s.
If another Sprout effect is triggered during its initial duration, the initial effect will be removed. DMG dealt by Sprout is considered Elemental Skill DMG.

TP2: The Languid Wood

When a character within the Cuilein-Anbar Zone triggers Burning, Quicken, Aggravate, Spread, Bloom, Hyperbloom, Burgeon, or Lunar-Bloom reactions, the Zone's duration will be increased by 1s.
A single Trump-Card Kitty can be extended this way by up to 3s.

TP3: Gliding Champion of Sumeru

Decreases gliding Stamina consumption for your own party members by 20%.
Not stackable with Passive Talents that provide the exact same effects.

C1: Deepwood Patrol

When in the party and not on the field, Collei's Energy Recharge is increased by 20%.

C2: Through Hill and Copse

The Ascension Talent Floral Sidewinder is changed to this:
The Floral Ring will grant the character the Sprout effect from Floral Sidewinder upon return, dealing 40% of Collei's ATK as Dendro DMG to nearby opponents for 3s.
From the moment of using Floral Brush to the moment when this instance of Sprout effect ends, if any of your party members triggers Burning, Quicken, Aggravate, Spread, Bloom, Hyperbloom, Lunar-Bloom, or Burgeon reactions, the Sprout effect will be extended by 3s.
The Sprout effect can only be extended this way once. If another Sprout effect is triggered during its initial duration, the initial effect will be removed. DMG dealt by Sprout is considered Elemental Skill DMG.
You must first unlock the Ascension Talent "Floral Sidewinder."
