Charlotte is the Steambird reporter from Fontaine, and in combat she is a Burst-driven Cryo healer for the whole party. She is not a slow channel healer: she dumps a large heal on every party member the moment she casts her Burst, then keeps applying Cryo and light healing through a 4-second field.
| Stat | Value / Note |
|---|---|
| Rarity / Element / Weapon | 4-star / Cryo / Catalyst |
| Base HP | 10,766 |
| Base ATK | 173 |
| Base DEF | 546 |
| Ascension bonus | +24% ATK (not HP - the first hint that she is an ATK healer) |
| Energy / Cooldown | 80 energy / 20s (high for a 4-star) |
This section exists for everyone searching how Charlotte's healing is calculated. The complete expression is:
Heal = (ATK x talent multiplier + flat value) x (1 + Healing Bonus)
| Talent Lv. | Cast healing (all 4 members) | Kamera healing (active only) | Unlock |
|---|---|---|---|
| Lv.1 | 256.6% ATK + 1608 | 9.2% ATK + 57 | Base |
| Lv.4 | 320.7% ATK + 2131 | 11.5% ATK + 76 | Ascension 2 (Lv.40) |
| Lv.7 | 384.9% ATK + 2775 | 13.8% ATK + 99 | Ascension 4 (Lv.60) |
| Lv.10 | 461.8% ATK + 3539 | 16.6% ATK + 126 | Ascension 6 (Lv.80) + books |
| Lv.13 | 545.2% ATK + 4424 | 19.6% ATK + 158 | Constellation C3 (+3) |
Important: the cast heal applies to all four party members at once, so multiply by four for the total healing of one Burst. The Kamera heal only touches the active character.
| Source | Value | Note |
|---|---|---|
| Circlet main stat (5-star +20) | 35.9% | Always secure this first |
| Song of Days Past / Ocean-Hued Clam 2pc | 15% | Both sets also give a 4pc effect |
| Diversified Investigation passive | 5% / 10% / 15% | Scales with other Fontainians in the party |
A typical healer build lands on 15% + 35.9% = 50.9%. Add three other Fontainians (Furina, Neuvillette, Wriothesley) and you reach 65.9%.
| Tier | ATK | Burst Lv. | Healing Bonus | Cast heal (per member) | Formula |
|---|---|---|---|---|---|
| Starter (C0) | 1,400 | Lv.8 | 50.9% | ~13,200 | (1400x4.105+3016)x1.509 |
| Mid (recommended) | 1,800 | Lv.10 | 65.9% | ~19,700 | (1800x4.618+3539)x1.659 |
| Endgame (C3) | 2,200 | Lv.13 | 65.9% | ~27,200 | (2200x5.452+4424)x1.659 |
For reference, most 5-star DPS units sit between 14,000 and 20,000 HP. A mid-investment Charlotte refills the entire party from near-death in a single Burst - that is exactly why Furina teams want her.
During the 4-second Newsflash Field the Kamera keeps healing the active character at 16.6% ATK + 126 (Lv.10). At the mid tier above that is about 705 per tick. Do not expect it to hold against sustained damage: her job is the big instant heal, not a heal-over-time.
| Set | Effect | When to use |
|---|---|---|
| 4pc Song of Days Past | 2pc: 15% Healing Bonus. 4pc: records healing and converts it into Waves of Days Past, adding flat DMG to the active character's attacks | Best overall - overflow healing becomes damage |
| 4pc Ocean-Hued Clam | 2pc: 15% Healing Bonus. 4pc: healing builds bubbles that deal Physical DMG | Pure healer with a bit of damage |
| 4pc Noblesse Oblige | 2pc: 15% Healing Bonus. 4pc: +20% party ATK after Burst | When nobody else runs Noblesse |
| 4pc Tenacity of the Millelith | 2pc: HP. 4pc: party ATK buff on Skill hits | Not recommended - needs Hold Skill uptime and she usually taps |
| 4pc Golden Troupe / Blizzard Strayer | Damage-leaning | Off-field sub-DPS builds only |
| Piece | Primary | Alternative |
|---|---|---|
| Sands | Energy Recharge | ATK% |
| Goblet | ATK% | Cryo DMG (sub-DPS only) |
| Circlet | Healing Bonus | CRIT Rate (with Favonius Codex) |
Substat order: Energy Recharge (to requirement) > ATK% > flat ATK. With Favonius Codex, CRIT Rate jumps to the front right after ER.
| Weapon | Solo Cryo | Double Cryo | Triple Cryo |
|---|---|---|---|
| Prototype Amber | ~185% | ~160% | ~150% |
| Other catalysts | +30 to +45% | +30 to +45% | +30 to +45% |
Practical advice: aim for 200% first, then trade the sands for ATK% once your rotation is stable. R5 Prototype Amber softens the requirement a lot, which is one more reason it is the default pick.
| Weapon | Rarity | Why |
|---|---|---|
| Prototype Amber | 4-star craftable | HP% substat; after Burst it restores energy to Charlotte and HP to the whole party. Default pick |
| Favonius Codex | 4-star gacha | ER substat; CRIT hits generate particles for the team |
| Thrilling Tales of Dragon Slayers | 3-star gacha | Huge ATK buff to the next character - common in hyper-carry teams |
| Oathsworn Eye | 4-star event | ATK% substat plus energy after using the Skill - solid free option |
| Sacrificial Fragments | 4-star gacha | Skill reset chance for an extra particle burst (needs high refinement) |
| Kagura's Verity | 5-star limited | Off-field damage weapon; poor value in a pure healing slot |
| Team | Members | Why it works |
|---|---|---|
| Furina core (best) | Furina + Neuvillette or Wriothesley + Charlotte + Kazuha | Furina drains party HP for buffs and needs a healer who tops up everyone at once. Charlotte's Burst does exactly that and maxes Fanfare instantly. Furina is also a Fontainian, so she boosts Charlotte's own Healing Bonus |
| Freeze | Ayaka + Xingqiu or Yelan + Kazuha + Charlotte | Constant off-field Cryo holds the freeze while she covers healing |
| Mono Cryo | Ganyu + Shenhe + Kazuha + Charlotte | Triple Cryo drops ER needs to about 150%; Shenhe amplifies Cryo DMG |
| Hyperbloom / Hyperfridge | Dendro + Hydro + Electro core + Charlotte | Her Cryo application is slow enough that it rarely steals reactions |
Rule of thumb: if the team needs one button that refills everyone, Charlotte is the cheapest answer among 4-stars. If you need sustained healing on field, use Kokomi or Baizhu instead.
Talent priority: Burst only. All healing lives in the Burst. The Skill only affects her own Cryo damage and mark frequency, and Normal Attacks are irrelevant. Short on resources? Leave Skill and Normal Attack at level 1.
| Constellation | Name | Value |
|---|---|---|
| C1 | A Need to Verify Facts | After the Burst heals someone, they get Verification, healing 80% of ATK every 2s for 6s (3 ticks). At 1,800 ATK and 65.9% Healing Bonus that is roughly 2,390 per tick, about 7,200 extra total |
| C2 | A Duty to Pursue Truth | Skill hitting 1/2/3+ enemies grants Charlotte +10%/20%/30% ATK for 12s, indirectly raising her healing |
| C3 | An Imperative to Independence | Burst level +3 - the most direct healing increase |
| C4 | A Responsibility to Oversee | Key constellation: the Burst deals +10% DMG and restores 2 energy when it hits marked enemies, up to 5 times per 20s (10 energy), easing ER a lot |
| C5 | A Principle of Conscience | Skill level +3 - marks and Cryo damage only, no healing |
| C6 | A Summation of Interest | When the active character's Normal or Charged Attacks hit a Focused Impression target, a coordinated attack deals 180% ATK Cryo DMG and heals 42% ATK, once every 6s |
Verdict: C0 is fully functional - she is one of the easiest 4-stars to slot in. C1, C3 and C4 are the three that matter for healing and uptime.
Heal = (ATK x talent multiplier + flat value) x (1 + Healing Bonus). At Burst Lv.10 the cast heal is 461.8% ATK + 3539 and it applies to all four party members at once. At 1,800 ATK with 65.9% Healing Bonus that is roughly 19,700 HP per member.
ATK. Her healing scales entirely off ATK, and her ascension bonus is +24% ATK. Stacking HP does nothing for her healing - it is the single most common mistake.
Her Burst costs 80 energy. With Prototype Amber, roughly 185% solo Cryo, 160% with two Cryo units and 150% with three. Other catalysts need 30-45% more, so about 200-230%. Build toward 200% first.
Only the Elemental Burst. Healing depends purely on the Burst level; the Skill affects only her own Cryo damage and mark frequency, and Normal Attacks are irrelevant. Leave both at level 1 if resources are tight.
Yes, especially for Furina teams - Furina wants a healer who refills the whole party in one cast, and Charlotte is the cheapest 4-star answer at C0. If you need long sustained on-field healing, Kokomi or Baizhu fit better.
Artifacts: 4pc Song of Days Past is best overall (Healing Bonus plus converting overflow healing into damage); 4pc Ocean-Hued Clam for a pure healer; 4pc Noblesse Oblige if nobody else runs it. Weapon: craftable Prototype Amber first, then Favonius Codex, or Thrilling Tales of Dragon Slayers in hyper-carry teams.
