Release3.0
Tighnari's cheerful apprentice is a free, reliable off-field Dendro applier. Her Burst drops Cuilein-Anbar, which bounces around and keeps applying Dendro, and her Skill's Floral Ring leaves a lingering Sprout on your active character. She is outclassed by 5-star Dendro supports, but she still fills Quicken, Hyperbloom and Nilou Bloom teams at almost no cost.

In Nilou teams the Bountiful Cores use the trigger's Elemental Mastery, so an EM Collei makes Nilou's cores hit much harder.

Tighnari Quicken

Budget Hyperbloom
Two free Dendro characters create cores with Xingqiu's Hydro, and Kuki turns them into Hyperbloom while healing.
Guide
How to play
How she works
- Floral Brush (Skill, 12s cooldown) throws a boomerang Floral Ring that hits on the way out and on the way back.
- Floral Sidewinder (A1): if the party triggered Burning, Quicken, Aggravate, Spread, Bloom, Hyperbloom, Burgeon or Lunar-Bloom before the ring returns, the active character gets Sprout, which deals Dendro DMG around them for 3s.
- Trump-Card Kitty (Burst, 60 Energy) creates a Cuilein-Anbar zone where the doll bounces and deals AoE Dendro DMG. The Languid Wood (A4) extends the zone by 1s per reaction, up to 3s.
Rotation
- E, then Q right away so she catches her own particles.
- Swap out: Cuilein-Anbar keeps applying Dendro while your other characters react.
- In long rotations, cast E again before leaving.
She is a support first: Energy Recharge comes before damage stats, and her Burst is her main source of Dendro.
Strengths
- Free for everyone: clear Spiral Abyss Floor 4-3 (Adventure Rank 20+) in the permanent "Curtain of Leaves" event
- Strong off-field Dendro application from her Burst
- Can carry Deepwood Memories for the team's Dendro RES shred
- C4 gives the party +60 Elemental Mastery
Weaknesses
- High Energy Recharge needs for a 60-Energy Burst
- Low personal damage
- Her Burst zone is static, so moving enemies can escape it
- Nahida, Lauma or the Dendro Traveler often do her job better
