Firtho

About Firtho

"Dispensing drugs, performing surgeries, chemical analysis, forensics... I'm the only person in this city who meets all your needs, no?" Her official character title page, revealed July 30, 2026, tags her The Medical Lancet and calls her a reliable examiner, a doctor, and a close friend who lives alongside death day after day, bearing witness to the final testimonies of the deceased. An earlier title page carried a different line: "Life has not been kind to me. Death, on the other hand... has been a truer friend." Trace the Reaper's steps, and let the deceased spill the truth. A cold and exacting doctor who conducts medical research in secret chambers within her clinic, Firtho is capable of applying her medical expertise in combat to deliver a fatal blow to adversaries. Due to a congenital illness she must wear a life-sustaining device at all times; she wants no pity and hates being a burden. In the endless river of death, life is only a coincidence along the way. Shown in the Monotype closed beta as a Radiatio Guardian who fights with a saw cleaver and syringes, blending defensive durability with the cleansing and sustain the Radiatio attribute is known for; treat exact kit details as beta-stage.

In the Dichotomy Beta story, Firtho is the Detective's blunt childhood friend and the coroner behind the corner clinic in a quiet, forgotten district, nicknamed 'Miss Mortis' for a reclusive childhood spent watching autopsies. She brews the stabilizer that holds the Detective's nightmares at bay, and quietly inoculates terrified gangsters against a contagious rash with an experimental serum rather than experimenting on them as they fear.

Her own quest is a locked-room 'vampire' case at Williams Manor. To prove a death was faked, she injects a tetrodotoxin nerve agent into her own arm and wears a mask through the night, counterfeiting death to expose the trick. The case cuts deep, since the culprit Baron Edgar was a colleague of her late father Irwin at the Royal Academy. Read the full case in the Silver Palace story recap.

Personality: A cold, exacting clinic doctor who patches people up and, when needed, takes the field herself. Her medical tools double as weapons.
Appearance: Closed beta footage shows her with a saw cleaver and syringe-based tools.
Birthday: 3rd of September
Likes: Medical research, scalpels, rainy days
Dislikes: Unwanted concern, failing to diagnose symptoms, heart abnormalities, death
Skills: Medical affairs, the usage of medicines and poisons, surgery and augmentations

In-game profile

The Corner Clinic's doctor, the daughter of the Royal Academy scholar Erwing, and my childhood friend.

She was stricken with a congenital heart condition throughout her youth. Yet the mechanical heart that now beats within her allows her a new lease of life.

She fixed me with a somewhat resentful gaze upon my return to Silvernia, perhaps disgruntled that I left for three years without so much as a goodbye.

What Firtho calls you as Trust rises

Childhood FriendHidden DesireHeartbeat Like None Other

Intel

Elder Brother: Lost touch due to differing values, not seeing eye to eye.
Further Information: I: Though she may come across as intimidating or even scary, it's usually just a means by which she masks her concern for me.
Further Information: II: She possesses two coexisting yet conflicting sides: one burning with an academic curiosity for medicine, and the other filled with fear of death.
Further Information: III: She's grown more determined, more independent too. Yet she'll always hold a special place in her heart for me.

Firtho's Charged Skill provides 10% more healing. After she uses a Charged Skill, all characters on the team take 10% less DMG for the duration of the buff.

Fate-Defying Lancet

The buff from Firtho's Charged Skill also increases the Amplitude Coefficient of all characters on the team by 16%.

Shadow of the Heart

After Firtho unleashes a Charged Skill, her Basic Attack DMG is increased by 24% for 6s.

Early Cooperation

After Firtho uses her Tactical Assault, she recovers 20% Silverdrips. For each buff stack her Charged Skill grants, she recovers 2% Silverdrips.

Firtho Trust and Gifts

The gifts Firtho prefers, what each Trust level costs, and what it pays out.

Firtho prefers Silverium Terrarium, Scientific Horizons: The Compendium and Enamel Pocket Watch. Each one is worth 100 Trust EXP, so 8 of them cover the 780 Trust EXP between Lv.1 and Lv.5. The Gift Shop charges a flat 10,000 Ounce per gift, which puts a maxed Trust level at 80,000 Ounce.

Preferred gifts

Silverium Terrarium

+100 Trust EXP

A small terrarium that houses Silverium beings. It's said one can even glimpse them fading into inactivity, returning to the Argent Strand.

These sold fast upon release, a desirable item for Silverium enthusiasts.

Scientific Horizons: The Compendium

+100 Trust EXP

A hefty essay collection detailing a range of theses that have stirred up debate in modern scientific spheres.

Contains many contentious topics, hence many half-jokingly refer to it as the cutting edge of Silvernian research.

Enamel Pocket Watch

+100 Trust EXP

A watch of outstanding craftsmanship. Another half-century could pass, and its hands would still be accurate to the millisecond.

The owners of such watches tend to engrave their name on the back, the signature to a contract with Father Time himself.

Daily

Character Quote

Life has not been kind to me. Death, on the other hand... has been a truer friend.

Scattered Thoughts

I'd rather be a deadly poison than some greenhouse flower.

Inner Feelings

As a child with a heart disorder, I always detested the pity with which people looked at me... I was weak then, but now, I'm strong enough to face the truth. Strong enough to say goodbye.

Greeting

The clinic is closed today. Explaining conditions and treatments to patients is putting a serious toll on my circulatory and nervous systems.

Outside the Detective's Office

I've only come today to monitor your activities and see how many ways you can get yourself injured.

Casual Chat

If you are experiencing a mental block, I do have some psycho-activating agents. In safe doses, of course.

Riding: I

The time a physician spends travelling may be the difference between life and death for the patient.

Riding: II

With transport, house calls are far less annoying.

Riding: Speeding Up

Faster.

Riding: Sudden Stop

(interjection)

Riding: Flying

Straight line, shortest path? Figures you'd say that.

Lucky Find: I

I have little use for this. It's yours.

Lucky Find: II

Remember to disinfect them.

Inspect

Time to observe and diagnose.

Expose

I have the conclusion.

Battle

Battle Start: I

I've seen my fair share of disagreeable patients.

Battle Start: II

Apply restraints on any uncooperative patients.

I'm taking over.

Tactical Assault: II

Go and take a break.

I'll handle it.

Back down, all of you.

Not so challenging.

Vital organs unharmed.

Wounded

No need to worry...

Exhausted

I can dress the wound myself...

Ultimate: I

Commencing emergency surgery.

Ultimate: II

Prepare for surgery.

Execute: I

The anatomical structure is evident.

Execute: II

I know where to make the first incision.

Victory: I

Good. Now comply with my treatment.

Victory: II

Any injuries? I'll take a look.

Other

First Meeting

Dead men don't talk? I beg to differ. I can secure testimonies even from the deceased. Which is why you're here, is it not?

Preparation for Action: I

When it comes to settling people down and shutting them up, I have my ways.

Preparation for Action: II

There's more to me than meets the eye. In fact, I've been trained to handle patient disputes too.

Potential Growth

Hmph, mind your own... I never said I didn't want it.

Potential Break

Dispensing drugs, performing surgeries, chemical analysis, forensics... I'm the only person in this city who meets all your needs, no?

In Rain

The efficacy of drugs may be influenced by weather, so make sure you acquire my advice before use.

Nighttime

It's at night that I speak with the dead. Hurhur. I wonder what the bodies will tell me tonight... hurhurhurhur...

At the Corner Clinic

Work at my clinic is manageable so long as you don't come to me with your problems. That'll be great news for both my patients and me.

Potential Break Costs

Each Potential Break raises Firtho's level cap to the level shown. Taking Firtho through all 6 costs 134,400 Ounce plus Rectified Decay Concentrate, Quick Electrified Core, Fledgling Feather, Juvenile Feather, Hunter Feather and Quilled Feather. Firtho is Radiatio, so the Reactor Attribute material is Rectified Decay Concentrate.
