Tooth Fairy sits in a rare spot in Reverse: 1999's roster: a 6-star healer who doubles as one of the game's strongest crit amplifiers. Her kit does three things at once, healing the team, stripping debuffs, and shredding enemy Critical Resist and Critical DEF, which makes her genuinely useful in almost any crit-focused lineup. The catch is that she needs the right carry to make those debuffs count.
Tooth Fairy character overview
What kind of character is Tooth Fairy?
Tooth Fairy is a 6-star, Star Afflatus character who deals Mental damage and sits in the Support class. Her tag set covers Heal, Debuff, and Purify, which is an unusually broad utility profile for a single unit. According to Prydwen's character review, her debuffs can increase your team's effective Crit Rate by 40% and Crit DMG by 15% when her full kit is active. That number assumes both her Empty Gums [Confusion] stacks and her Baby Tooth Collector Insight effects are running simultaneously.
The flip side is that she is extremely fragile. Prydwen's review notes she sits at roughly the same base HP and DEF as Charlie, which is not a compliment for a character you want on the field every round.
Tooth Fairy skill breakdown
Empty Gums
Empty Gums is a single-target Mental damage attack that inflicts 1 stack of [Confusion] on the enemy for 1 round. At rank 1 it deals 150% Mental DMG, rank 2 bumps that to 250%, and rank 3 reaches 450% (per Prydwen's skill listing). Each [Confusion] stack reduces the target's Critical Resist by 25%, and stacks are tracked independently, so timing matters.
The core tip from Zilliongamer's guide: always open with Empty Gums before any damage-dealing incantation so the [Confusion] debuff is active when your carry hits. This is the single most impactful habit to build with Tooth Fairy.
Stack [Confusion] before your carry acts. Since each stack has its own timer and lasts only 1 round, you need to re-apply it consistently to keep the -25% Critical Resist penalty active.
Lullaby
Lullaby is a mass heal that restores HP equal to a percentage of Tooth Fairy's ATK for all allies. The scaling goes from 80% ATK at rank 1, to 120% at rank 2, and 200% at rank 3. Critically, this heal comes with a built-in +30% Critical Rate bonus on the heal itself, meaning it can crit and output significantly more HP restoration than the base numbers suggest. Pairing this with ATK-focused Psychubes directly amplifies healing output.
Song for the Bad Tooth (Ultimate)
Song for the Bad Tooth deals 500% Mental DMG to a single target and carries a +30% Crit Rate on the attack itself. If it scores a critical hit, it purifies [Stats Down], [Negative Status], and [Control] effects from all allies. As Prydwen's review points out, team-wide debuff removal is rare in Reverse: 1999, making this ultimate genuinely valuable in content that throws heavy debuffs at your team.
The problem is consistency. If enemy Critical Resist is high enough that the ultimate fails to crit, the cleanse never triggers. This becomes a real issue in late-game content where enemies naturally have elevated Crit Res values.
Do not rely on Tooth Fairy's cleanse as a guaranteed answer to enemy debuffs. In high-difficulty content with elevated enemy Crit Resist, her ultimate may fail to land the critical hit needed to trigger the purify effect.
Tooth Fairy skill selection
How does Baby Tooth Collector work?
This is Tooth Fairy's Inheritance passive, and it is the engine that makes her a crit support rather than just a healer.
- Insight I: Tooth Fairy enters battle with 3 [Baby Tooth] stacks. Each time any team member actively uses an incantation, she gains 1 more. At the start of each round, if she has 5 stacks, they are consumed to reduce the entire enemy team's Critical Resist and Critical DEF by 15% for 1 round.
- Insight II: Healing Done +10% on entering battle. Straightforward but meaningful for a healer who scales off ATK.
- Insight III: When the [Baby Tooth] Stats Down effect triggers, all allies recover 10% of their missing HP. She also enters battle with 2 additional [Baby Tooth] stacks (5 total at Insight III).
With Insight III active, Tooth Fairy enters a fight with 5 stacks already, meaning the enemy team takes the -15% Crit Resist and -15% Crit DEF debuff from round 1 without you needing to spend any actions building up stacks. From there, the passive regenerates through normal incantation use.
Reaching Insight III is a significant resource investment, but the round-1 debuff activation it provides makes a noticeable difference in timed content. Prioritize it once you have the materials.
Tooth Fairy Portray upgrades: are they worth it?
Portray levels come from duplicate pulls, so this section is mainly relevant if you happen to pull multiple copies.
Portray 5 is the standout upgrade, pushing the passive debuff from -15% to -25%, which is a substantial amplification for any crit carry. Portray 2 is also meaningful since extending the debuff duration by 1 round gives more breathing room in longer fights. Portrays 1 and 3 are purely offensive damage bumps that matter less given Tooth Fairy's primary role.
What are the best Psychubes for Tooth Fairy?
Based on Zilliongamer's Psychube rankings and Prydwen's build recommendations, here are the top options:
Tooth Fairy Psychube options
1. Beyond Wonderland (Best in slot)
Beyond Wonderland scales Max HP at Lv 1 (10%) up to 16% at Lv 60, which helps offset Tooth Fairy's low natural bulk. Its passive increases her healing rate by 3% each time she uses a debuff incantation, stacking up to 4 times, and adds 7% Crit Rate at Lv 1. Since Empty Gums is a debuff incantation you will use frequently, this Psychube stacks naturally through normal play and synergizes with her crit-dependent healing and ultimate.
2. That Inquisitive Dear
That Inquisitive Dear boosts Healing Done by 12% at Lv 1 (18% at Lv 60). Its passive triggers when Tooth Fairy casts a basic incantation debuff, healing the lowest-HP ally for her ATK x24% (at Lv 1). This gives her a targeted spot-heal on top of her mass heals, which is useful in fights where one ally takes disproportionate damage.
3. Laughter and Laughter
Laughter and Laughter reduces DMG Taken by 4% at Lv 1 (10% at Lv 60) and adds 3% Healing Done per round at the start of each round, stacking up to 4 times. This is the defensive option for players who find Tooth Fairy dying before she can contribute. The DMG reduction directly addresses her squishiness.
4. Thunderous Applause
Thunderous Applause gives 10% Crit Rate at Lv 1 (16% at Lv 60) and amplifies Crit DMG by 16% (Lv 1) when her single-target attacks crit. This is the offensive pick if you want to maximize the chance that Song for the Bad Tooth lands its critical hit and triggers the team cleanse. Prydwen's recommended build targets 43% Crit Rate specifically to make the cleanse reliable, and this Psychube helps reach that threshold.
Prydwen's high-ATK/Crit build for Tooth Fairy targets 43% Critical Rate to ensure her ultimate's cleanse effect fires consistently. If you find the cleanse is unreliable in your current build, check whether you are hitting that Crit Rate target before swapping Psychubes.
What is the best team for Tooth Fairy?
Tooth Fairy's value scales directly with how much your carry benefits from crit amplification. Her debuffs reduce enemy Critical Resist and Critical DEF, which only matters if your carry is actually landing critical hits and dealing crit damage. Pairing her with a carry that ignores crit entirely wastes most of her kit.
The ideal team structure around Tooth Fairy:
- A crit-focused carry who benefits from -Crit Resist and -Crit DEF debuffs on enemies
- Tooth Fairy in the support/healer slot
- A second support who can cover Tooth Fairy's weaknesses or amplify the carry further
Tooth Fairy is at an Afflatus disadvantage in some matchups, and Prydwen's review explicitly warns that she struggles with high incoming damage in those situations. In those fights, consider whether you need a tankier healer or a second defensive unit.
Tooth Fairy team setup
Euphoria upgrades: what changes?
Tooth Fairy has Euphoria upgrades available that significantly rework her kit. At Tier I, her Insight passive shifts from accumulating [Baby Tooth] through incantation use to a system tied to [Eureka] consumption by allies. Consuming 5 [Baby Tooth] at the start of a round instead boosts DMG Dealt for Impromptu Incantation attacks by +4% per stack and inflicts [Bad Tooth] on all enemies, a debuff that reduces Critical Resist and DEF by 10% per stack (up to 5 stacks). The Tier I Euphoria also adds a healing component: each [Baby Tooth] consumed heals allies for 5% of their lost HP.
Tier II changes Empty Gums to grant [Continuous Action I] for 1 round instead of inflicting [Confusion], and Tier III makes Lullaby boost Impromptu Incantation DMG by +20%. Tier IV adds [Neuralgia] to the ultimate, dealing Genesis DMG to the target based on total Impromptu Incantation damage taken.
The Euphoria system shifts Tooth Fairy toward a more Impromptu Incantation-focused playstyle. If you are running a team built around that mechanic, the upgrades are meaningful. If not, the base kit remains effective without them.
