The Cat's Tail's star bartender combines a sturdy shield, healing and Cryo particles in one easy-to-build 4-star. Her Witch's Revelation upgrade (Luna VIII) turned her into a real Stellar Glimmer support: at C6 her Burst gives the active character 200 Elemental Mastery and +40% Stellar-Conduct or Stellar Swirl DMG, making her a strong option for Sandrone, Cyno and Vesna.

Stat targets

  • Energy Recharge with two other Cryo units: about 200% with Favonius, 225% with another bow, 175% with Sacrificial Bow (double Skill)
  • With one other Cryo unit: about 235% with Favonius, 290% with another bow, 255% with Sacrificial Bow
  • Then as much HP as possible; CRIT Rate only with Favonius Warbow

Talent priority

Elemental Skill
Elemental Burst
Normal Attack

Her shield duration caps at Skill level 7; further levels only add absorption. Her Burst level only raises healing, so neither talent is urgent. Keep your active character above 50% HP so the C6 EM buff applies instead of the healing bonus.

Teams

Recommended teams

Sandrone Stellar-Conduct

Sandrone
Yae Miko
Odette
Diona

C6 Diona comes close to Qiqi in this premium team: she shields Sandrone, adds 200 EM and +40% Stellar-Conduct DMG, and her particles often let Sandrone Burst every rotation.

Vesna Stellar Swirl

Vesna
Odette
Faruzan
Diona

Odette and C6 Faruzan stack buffs while Diona protects Vesna's long field time; Yumemizuki Mizuki can replace Vesna.

Cyno Stellar-Conduct

Cyno
Yae Miko
Odette
Diona

Odette enables Stellar-Conduct, Yae Miko adds Electro, and C6 Diona (Favonius, around 240% ER) supplies Cryo and a shield for Cyno's long melee combos, only slightly behind Qiqi.

Guide

How to play

How she works

  • Icy Paws (Skill): the Hold version fires 5 paws, creates a 12s shield scaling with her Max HP (+75% absorption) and generates about 4 Cryo particles. Tap (2 paws) is only used in some tight rotations, as in Prydwen's Sandrone and Cyno teams.
  • Signature Mix (Burst, 80 Energy) creates a 12s field that heals characters inside and deals light Cryo DMG; enemies in it lose 10% ATK.
  • Choice Treasures (Witch's Revelation passive): for 20s after her Skill, she fires 3 extra Icy Paws whenever the party triggers Superconduct, Stellar-Conduct, Cryo Swirl or Stellar Swirl (once every 3.5s). She also enters Radiance: Stellar-Conduct inside a Polestar Field, or Radiance: Stellar Swirl for 8s after a nearby Stellar Swirl.
  • C6: characters in her field get 200 EM (above 50% HP) or +30% incoming healing (below 50%), and under Radiance they also deal +40% Stellar-Conduct/Superconduct or Stellar Swirl/Cryo Swirl DMG. Her Max HP rises by 25%.

Rotation

  1. Hold E for the shield and particles, then Q on your carry's position.
  2. Swap to the main DPS and keep them inside the field.
  3. In 15s Stellar Swirl rotations, her Burst can be used every other rotation.

Without C6, her Burst is just healing: skip it if the team does not need it and focus on her Hold Skill.

Strengths

  • Shield and healing in one slot: very comfortable sustain
  • At C6, 200 EM and +40% Stellar Glimmer DMG for the active character
  • Hold Skill is a reliable Cryo battery (about 4 particles)
  • Cheap to build: ER and HP%, many support sets work

Weaknesses

  • Almost all of her buffs are locked behind C6
  • Her Burst field is fixed and only buffs the active character inside it
  • Long cooldowns and an 80-Energy Burst
  • Slow Cryo application compared to other off-field Cryo units

Notable dupes · Constellation

C1
Solid upgrade

Refunds 15 Energy when her Burst ends: effectively a 65-Energy Burst.

C2
Optional

+15% shield absorption; its shared shield only matters in co-op.

C6
Big upgrade

200 EM and +40% Stellar-Conduct/Stellar Swirl DMG in her field, plus 25% Max HP. This is what makes her meta-relevant (about +11% team damage in Prydwen's Sandrone calcs).
