Firtho Build

Implement stats are fixed, not rolled. Set data is fan-compiled from the game files; where each set drops is in the Implements guide.

The Priest and the Bread Thief

Best

HP % +24%

Increases the holder's Healing Bonus by 16%. After the holder provides healing, all other characters on the team gain CRIT DMG (equal to the holder's CRIT DMG ×6% + 16%) for 30s, up to a maximum of 42%.

Why: Each Second Heart heal hands teammates CRIT DMG based on her own CRIT DMG, up to 42%, and its 16% Healing Bonus shrinks what the HP drain costs her.

The Castaway's Tale

Alternative

HP % +26%

Increases the holder's Healing Bonus by 16%. After the holder provides healing, all other characters on the team gain Amplitude Multiplier (equal to the holder's Amplitude Multiplier ×6% + 16%) for 30s, up to a maximum of 42%.

Why: Same healing payout but in Amplitude Multiplier, for a Resonance carry such as Rex or Bentham.

Diamond Necklace

Alternative

HP % +20%

Increases the holder's Max HP by 20%. When the holder's Ultimate Charge Efficiency exceeds 140%, providing healing effects grants all characters on the team 25% CRIT DMG for 30s.

Why: A lower-level take on that team CRIT DMG buff, fixed at 25%, which needs her Ultimate Charge Efficiency above 140% first.

The Last Leaf

Alternative

HP % +20%

Increases the holder's Max HP by 20%. When the holder's Ultimate Charge Efficiency exceeds 140%, providing healing effects grants all characters on the team 25% Amplitude Multiplier for 30s.

Why: The early Amplitude version of the same idea, and its 20% Max HP helps cover Second Heart's HP drain.

Return From the Underworld

Alternative

Ultimate Charge Efficiency +30%

Increases the holder's Ultimate Charge Efficiency by 20%. Upon unleashing their Tactical Assault, their Healing Bonus is increased by 10% for 6s. When the holder provides healing, they grant the target 1 stack of Heartfelt Elegy. Each stack increases ATK by 2% for 36s, stacking up to 6 times.

Why: Instead of a team payout, each heal stacks up to 12% ATK on its target, so open with her Tactical Assault for the 10% Healing Bonus.

The Epiphany is the fifth gear slot, one per character. Duplicates raise its stats, never its effect. Effects are fan-compiled from the game files.

What every level costs is on the Firtho materials page.

1. Psyche IPathologist. 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.
2. Psyche IIFate-Defying Lancet. The buff from Firtho's Charged Skill also increases the Amplitude Coefficient of all characters on the team by 16%.
3. Psyche IIIShadow of the Heart. After Firtho unleashes a Charged Skill, her Basic Attack DMG is increased by 24% for 6s.
4. Psyche IVEarly Cooperation. After Firtho uses her Tactical Assault, she recovers 20% Silverdrips. For each buff stack her Charged Skill grants, she recovers 2% Silverdrips.
5. Psyche VDetective and Doctor. After Firtho uses her Ultimate, she increases the Radiatio DMG of all characters on the team by 15% for 40s.
6. Psyche VIShared Days. Firtho's Charged Skill DMG is increased by 15%. For each enemy her Charged Skill hits, the DMG of her next Ultimate is increased by 9%, up to a maximum of 27%.

Each Psyche costs one more copy of Firtho. Effects are fan-compiled from the game files. Our reading: Psyche I, Pathologist, matters most, adding 10% healing to her Charged Skill and another 10% team damage cut for the length of the buff; Psyche V's Radiatio bonus only helps when Captain Kaboom is on the team. The character progression guide explains the system.
