Tooth Fairy — Review & Analysis
- ATK-scaling AoE healing that self-adds 30% Crit Rate to the heal and is boosted a further 10% Healing Rate by Insight II — a steady sustain pillar.
- Ultimate cleanses Attribute Debuffs, Abnormal Status and Control for the whole team on a crit, breaking through debuff-heavy fights.
- Heals and buffs at once: Confusion lowers enemy Crit Resist and Baby Tooth shreds enemy Crit Resist/Defense, opening the way for the whole team to crit harder.
- Star Afflatus is countered by Plant, so against Plant enemies she takes 30% more damage and teams must be built with care.
- Her buffs depend on ramp-up: Baby Tooth needs 5 stacks to trigger and the Ultimate's cleanse only fires on a crit, so her value leans heavily on stacking enough Crit Rate and having the turns to build up.
Since both Tooth Fairy's healing and damage scale off ATK, level Incantation II (Lullaby) first to maximize AoE healing, then her Ultimate Ritual to keep the cleanse cycle up, with Incantation I last. Push her Insight ranks enough to unlock the passive (enemy Crit Resist/Defense shred and +10% Healing Rate). For Psychubes, pick ones that raise ATK and boost healing to suit her healer role; if you want to lean into her crit-opening kit, Crit Rate sources also pay off well.

Where to Get
Teams with Tooth Fairy
Tooth Fairy, Matilda and Voyager all tap into Confusion together with Crit — combining it across three kits at once outperforms any single carry doing it alone. Name Day keeps the line-up alive with Heal so that payoff has time to land.
