Hsin Build Guide

What to know before spending pulls

Every weapon in her current build list is a 5-star: Blooming Jadehaven, Lethean Elegy, Stringmaster, and Cosmic Ripples. This guide has not reviewed a 4-star option yet. That is a gap in the guide, not proof that she needs a weapon-banner pull. Her Echo set, Heart of Sworn Vigil, activates in both modes, so you do not need to farm two sets to try both teams.

Do you need the signature weapon?

Blooming Jadehaven (signature) has 588 ATK and 24.3% Crit Rate at level 90. Its passive gives 12% All-Attribute DMG Bonus. After she inflicts Electro Flare or triggers Unison Response, it Amplifies Resonance Skill DMG by 36% and ignores 10% of the target's Electro RES. While she is the active Resonator, it also Amplifies Electro Flare DMG taken by nearby targets by 30%. Both triggers match her two modes, so the passive works in either team. Lethean Elegy has the same 588 ATK and 24.3% Crit Rate. Its 32% Resonance Skill DMG Bonus and 8% DEF ignore only apply for 12s after she deals Echo Skill DMG, so you must use her main Echo before each damage window. Stringmaster trades ATK for Crit: 500 ATK and 36% Crit Rate, plus 12% Attribute DMG Bonus and up to 24% ATK from dealing Resonance Skill DMG. Cosmic Ripples is fourth on her list. Its passive raises Energy Regen and Basic Attack DMG, and Basic Attacks are not the main part of her damage. Tacet Codex has not run a damage test that ranks these weapons against each other.

Another character copy or the weapon?

Her S1 changes depending on the mode. In both modes, casting Formshift gives her 2 stacks of Radiance Ward, which make her immune to interruption and reduce DMG taken by 60% for 1s when she is hit. In Unison, S1 raises the multiplier of both Manifold Unison Intros by 15%, plus 10% per Unison Boon stack, up to 4 stacks. In Electro Flare, S1 tops Heart of Thunder up to 50 stacks when she enters combat and raises the multiplier of the Electro Flare DMG from her Resonance Skill. S2 raises the multipliers of all four empowered Heavy Attacks by 60%. Blooming Jadehaven gives a stat increase and a passive that work in both modes. These effects cannot be ranked from their descriptions, and Tacet Codex has not tested S1 against the signature.

Advice for your account

Easy rotation

1. In Answering Form, use Basic Attacks and her Resonance Skill until Answering Heart reaches 100. 2. Hold Normal Attack to cast Realm Wanderer, an empowered Heavy Attack that cannot be interrupted. This unlocks Formshift. 3. Cast Formshift (Resonance Liberation) to switch to Illumining Form and enter Heart Manifest. This also gives her 21 Edict, which summons a Soaring Pillar Coordinated Attack once per second while the active Resonator deals damage. 4. In Illumining Form, build Illumining Heart to 300, then tap Resonance Skill on the ground to cast Pillars Aligned and enter Mechanism Dominion. 5. Use Basic Attacks or Dodge Counters during Mechanism Dominion until Illumining Heart is empty, then hold Normal Attack for Beholding All Horizons. 6. Cast Pillars Across Heaven (Resonance Liberation) to end the form, then swap out with her Outro.

Opening vs. repeat cycles

Realm Wanderer and Beholding All Horizons each have a stronger version, Realm Protector and Stilling All Horizons, which uses a buff she can gain once every 24s. Whether the stronger version comes up depends on how long the rest of your rotation takes. Her S2 resets both cooldowns and restores 100 Answering Heart when she enters combat, once every 12s. In Unison, casting an Intro before Formshift gives her Unison for 5s, so enter with her Intro on later cycles.

Why this skill priority

Most of her damage is labeled Resonance Skill DMG even when it comes from another button. Realm Wanderer and Beholding All Horizons are Forte Circuit Heavy Attacks, Pillars Across Heaven is on her Liberation, and Manifold Unison is on her Intro. Forte Circuit and Liberation hold the most of these, so they come before Basic Attack.

Required buffs and assumptions

Her mode is set before combat and decides what her Outro does. In Unison, teammates who gain Unison pick up Shared Light, and her Outro gives them 20% All DMG Amplification for 30s. In Electro Flare, her Outro Amplifies the Electro DMG of every other teammate by 20% for 20s. Heart of Sworn Vigil gives 15% Crit Rate and 22.5% Electro DMG for 30s after she inflicts Electro Flare, gains Unison, or triggers Unison Response, so it stays active in either team without extra setup.
