A doctor who heals you in the clinic and brings a saw cleaver to the fight. Firtho is one of the more striking 4★ designs in Silver Palace, and the corrected data makes her more interesting than older guides suggested. Her confirmed stats and skill values are on the [Silver Palace Firtho](/characters/firtho) page.

**Firtho is a 4★ Radiatio (Light) character with the Guardian Identity**, the doctor of The Corner Clinic, fighting with a saw cleaver and syringes. (If you read elsewhere that she's a Fulmen DPS, that was wrong; beta data confirms Radiatio.) Her confirmed Combat Style is **Survival & Healing**, so she is the team's healer and buffer rather than a front-line damage soak.

## Element, role, and weapon

Radiatio is Silver Palace's Light element, tied to cleansing effects and debuff removal. Firtho's Combat Style is confirmed as **Survival & Healing** on the in-game Character Identity screen, one of only two characters in the preview roster with that label alongside Gratia. Guardian is her separate Identity, a narrative archetype rather than a battlefield job. Put together: she keeps the team alive and buffs its damage, and she does not deal the team's damage herself.

The weapon kit fits the character perfectly. A saw cleaver and syringes, medical tools turned weapons. It's grim, and it's on-theme for a clinic doctor who's seen the rough side of Silvernia.

## Who Firtho is

She runs The Corner Clinic, patching up the people the city forgets. When the situation demands it, she takes the field herself. Her doctor-meets-fighter angle, and the surgical toolkit picked apart in our [Firtho design breakdown](/blog/silver-palace-firtho-surgeon-design-breakdown), give her a distinct identity among the 4★ units.

## Combat profile

Her kit is now documented. **Second Heart** is the centrepiece: holding the Skill drains her own HP to build a team-wide ATK buff that stacks eight times and lasts 40s, healing the whole party over time and granting everyone except Firtho an instant heal. Her Passive, **Pain Management**, adds 20% team damage reduction for as long as that buff holds. **Amputation Saw** is her Basic Attack combo, **Visage of Death** her Ultimate, and **Law of Exchange** her Tactical Assault, all plain Radiatio damage. Five of her six Psyches key off the fully-charged Skill, so the rotation is simple: keep the buff up. Full skill and Psyche text is in the [Firtho title page post](/blog/silver-palace-firtho-doctor-title-page).

## How to build Firtho

Guardian gearing, using the [Motives framework](/motives):

* **Main stats:** HP%, DEF%
* **Utility:** Ultimate Charge Efficiency for Skill uptime, and healing potency, which her kit leans on directly
* **Attribute DMG%:** Radiatio DMG% if you're building a Radiatio-aligned team

She's a survive-and-support unit. Don't gear her like a DPS.

## Tier outlook and value

Firtho sits in the accessible-4★ band: a useful early healer whose real value spikes inside a Radiatio-aligned team that wants her cleansing utility. Early [tier lists](/blog/all-silver-palace-characters-tier-list-elements-roles) treat her as a serviceable front-liner rather than a meta pick, which is a perfectly good role for a unit you'll own without spending pulls.

Her best-case home is a Light [Resonance](/guides/resonance) team. Outside that, she's a generic sustain body, fine early and replaceable later.

## Is Firtho worth building?

For new and free-to-play players, she's worth a look, especially if you're leaning into a Radiatio team. She brings durability and Light utility at 4★ cost. Veterans with a deep roster may rotate her out for a specialized Guardian once the meta settles, but as an early investment she earns her slot. New here? The [Resonance guide](/guides/resonance) covers what an attribute-aligned team actually gains.

## In the Story: Dichotomy Beta

Firtho's Radiatio sustain fits the character you meet in the campaign: the Detective's blunt childhood friend, coroner of a corner clinic in a forgotten district, nicknamed "Miss Mortis." She brews the stabilizer that holds the Detective's nightmares at bay and secretly inoculates gangsters against a contagious rash rather than experimenting on them as they fear.

Her standout beat is a locked-room "vampire" case at Williams Manor, where she injects a tetrodotoxin nerve agent into her own arm and wears a mask through the night to prove a death was faked. See the [Silver Palace story recap](/blog/silver-palace-story-recap).
