Overview
Jiuyuan is a member of the Sterry Express who embodies mature and sophisticated elegance. Her combat style revolves around dual pistols and the Lethal Rose Pact marking system — she marks enemies, accumulates Rose Pact Bullets, and detonates all marks simultaneously for devastating burst damage through Pact Settlement.
Her defining strength is multi-target burst: in scenarios with many enemies, Jiuyuan can mark all of them and detonate simultaneously for massive AoE damage that scales with target count.
Key Mechanics
Lethal Rose Pact (Marking System)
| Property | Detail |
|---|---|
| Application | Final Basic Attack hit, Skill, Critical Riposte |
| Duration | Lasts until detonated or target leaves combat |
| Detonation | Ultimate’s Pact Settlement |
| Multi-Target | All marks in range detonate simultaneously |
| A2 Enhancement | Settlement DMG ratio +100%, heals team for 20% of accumulated damage |
Lethal Rose Pact is Jiuyuan’s core mechanic. Mark as many enemies as possible before using Ultimate to maximize Pact Settlement damage. Each mark detonates independently, making her damage scale linearly with target count.
Rose Pact Bullets
| Source | Bullets Generated |
|---|---|
| Basic Attacks (per string) | +2 |
| Skill (Intel Hunter) | +4 |
| Support Skill | +2 |
| Critical Riposte | +2 |
| Usage | Effect |
|---|---|
| Info-Guided Arts (hold Basic) | Consumes bullets, auto-targets marked enemies |
| Priority | Targets with Lethal Rose Pact are prioritized |
Rose Pact Bullets provide sustained damage between burst windows. Use Info-Guided Arts (hold Basic Attack) to spend bullets on marked targets for consistent DPS while building toward the next Pact Settlement.
Pact Settlement (Ultimate Detonation)
| Property | Detail |
|---|---|
| Trigger | Ultimate’s final hit |
| Effect | Detonates ALL Lethal Rose Pact marks in range |
| Scaling | More marks = more total damage |
| A4 Enhancement | +50% DMG ratio, affects targets in area |
| A2 Healing | Heals team for 20% of accumulated damage |
Pact Settlement is Jiuyuan’s primary burst tool. The damage scales with the number of marks active, making proper setup (marking all targets) essential before activation.
Best Build
Arc (Weapon)
| Priority | Arc | Why |
|---|---|---|
| BiS | Fireflies and the Forest | Anima DMG bonuses synergize with sustained damage style |
| Alt | Lost Radiance | Burst amplification for Pact Settlement windows |
| Budget | Devil’s Blood: Curse | Accessible option with offensive bonuses |
Cartridge Set
Fireflies and the Forest (4-piece) provides sustained damage bonuses that align with Jiuyuan’s mark-and-detonate playstyle.
Alternative: Lost Radiance for maximum Pact Settlement burst.
Stat Priority
| Slot | Main Stat | Sub-Stats |
|---|---|---|
| Module 1 | ATK% | CRIT DMG > CRIT Rate > Lakshana DMG% |
| Module 2 | Lakshana DMG% | CRIT DMG > CRIT Rate > ATK% |
| Module 3 | CRIT DMG | ATK% > CRIT Rate > Break Intensity |
ATK% is the top priority because it scales all damage including Pact Settlement detonation. CRIT DMG amplifies the burst from simultaneous mark detonation.
Skill Priority
Ultimate > Skill > Basic Attack > Support Skill
Ultimate receives the highest priority because Pact Settlement is Jiuyuan’s primary damage tool and scales with level.
Awakening Priority
| Priority | Level | Effect | Notes |
|---|---|---|---|
| 1st | A2 | Intel Turns Into Blades — +100% Pact DMG ratio + team heal 20% | Doubles Settlement damage + adds sustain |
| 2nd | A4 | Strike to Kill — +50% DMG ratio, affects area | AoE Settlement enhancement |
| 3rd | A6 | Know Every Secret — 200% DMG to marked targets when they cast skills (5s CD) | Passive damage against bosses |
| 4th | A1 | To Know, To Balance — +5% ATK per marked target (up to 15%) | Scales with target count |
| 5th | A5 | Intel Superiority — +8% DMG against marked targets | Consistent damage increase |
| 6th | A3 | Advantage Established — -4 additional Break on settlement | Break utility |
A2 is transformative — it doubles Pact Settlement damage and adds team healing, making Jiuyuan both a burst DPS and a pseudo-healer in one.
Resonance
| Level | Effect |
|---|---|
| R1 Doubled Capacity | Increases skill levels by 1 |
| R2 Unhindered Passage | Reduces Lakshana RES of marked targets by 10% |
R2 provides a Lakshana RES shred that benefits the entire team’s Lakshana damage against marked targets.

Gameplay Tips
Jiuyuan’s standard rotation begins with Intel Hunter (Skill) to pull enemies into range and apply Lethal Rose Pact. Follow with a full Basic Attack string to mark additional targets and generate Rose Pact Bullets. Use Info-Guided Arts (hold Basic Attack) to spend bullets on marked targets for sustained damage. Once all priority targets are marked, activate Ultimate for Pact Settlement detonation.
In multi-target scenarios, prioritize marking as many enemies as possible before using Ultimate. Each mark detonates independently, so Pact Settlement damage scales linearly with target count. This makes Jiuyuan one of the strongest characters for AoE burst in mob-heavy content.
At A2, Pact Settlement becomes a team heal (20% of accumulated damage). This allows Jiuyuan to function as a pseudo-healer in teams that can survive between Settlement windows, potentially freeing a team slot for another DPS.
Intel Hunter (Skill) pulls targets into range — use it as a grouping tool before Pact Settlement to ensure all marked enemies are within detonation range.
