Every move she makes is a checkmate.
In Honkai: Star Rail Version 3.4, the new 5-star Wind character Cerydra joins the battlefield. As one of the mysterious Golden Bough, she offers a unique support style centered on her signature “Military Merit” mechanic, redefining how tactical assistance and damage amplification can coexist. This article provides a full breakdown of her skills, passive mechanics, and Eidolon enhancements to help Trailblazers unlock her true potential.
▍Skills Overview
Cerydra’s entire kit is built around a progressive state mechanic: Military Merit → Nobility → Coup de Main. Through this transformation, she supports allies, removes debuffs, and enables powerful skill copying, all while subtly ramping up her own output. Her combat style is more than healing—she is a commander, turning the tide with precise support and explosive setup.
Basic ATK | Maneuver: Expeditious Relocation
Deals Wind DMG equal to 100% of Cerydra’s ATK to a single enemy.
A standard move with solid scaling and synergy with her Charge mechanic.
Skill | Ascend: From Pawn to Queen
Grants Military Merit to a designated ally and gives Cerydra 1 Charge (max 8).
At 6 Charges, Military Merit upgrades to Nobility, dispelling Crowd Control debuffs such as Freeze, Imprisonment, Fear, and more.
While under Nobility:
The ally gains +72% CRIT DMG for Skill DMG.
The next Skill used triggers Coup de Main, copying and using the Skill once before using the original Skill.
Afterward, 6 Charges are consumed, reverting Nobility to Military Merit.
Coup de Main cannot chain into itself, preserving balance while enabling burst windows.
Ultimate | All is Chess, Checkmate in Four
Deals Wind DMG equal to 240% of Cerydra’s ATK to all enemies and grants 2 Charges.
If no character has Military Merit, the ally in the first team slot receives it automatically.
An excellent damage-dealing Ultimate with built-in synergy reset logic.
Talent | Glory to the Imperator
Allies with Military Merit gain +24% ATK, scaling with Cerydra’s ATK.
Whenever they use Basic ATK or Skill, Cerydra gains 1 Charge.
Charge cannot be gained while Coup de Main is in effect.
Military Merit only applies to the most recent recipient—changing targets resets Charge to 0.
This elegant trade-off rewards consistency and tactical foresight.
Technique | First-Move Advantage
After using the Technique, Cerydra gains Military Merit.
When the active character is switched, Military Merit transfers to them.
At the start of the next battle, the character with Merit will receive an automatic Skill cast from Cerydra without consuming Skill Points (SP).
▍Stat Boosts
Cerydra’s stat passives tell a bold story:
Wind DMG Boost: +22.4%
ATK: +18.0%
HP: +10.0%
With the Seeker passive (E1), if Cerydra’s ATK exceeds 2000, every 100 extra ATK grants +18% CRIT DMG, up to a staggering +360%.
At E2, she gains +100% CRIT Rate, allowing for total CRIT-focused builds without the need for CRIT Rate relics.
This makes her a perfect hybrid support/damage dealer, scaling well into mid to high-level content.
▍Eidolon Analysis
Cerydra’s Eidolons dramatically enhance both her team utility and personal damage ceiling, especially at E2 and E6.
E1 | Crown of Absolute Claim
Characters with Military Merit ignore 15% DEF when dealing DMG.
While under Nobility, they ignore an additional 18% DEF for Skill DMG.
A solid boost to the team’s break potential and precision kills.
E2 | Aspiration of the Collective
Characters with Military Merit deal +40% DMG.
If at least one ally has Military Merit, Cerydra gains +160% DMG.
This turns her into a true offensive hybrid, excelling in coordinated strike setups.
E3 | Burning of the Ancient Laws
+2 Skill Levels (up to Lv. 15), +1 Basic ATK Level (up to Lv. 10).
E4 | The Realms Reforged
Cerydra’s Ultimate DMG multiplier increases by +240%, turning it into a full-board nuke.
E5 | A Reckoning of Deeds
+2 Ultimate Levels (up to Lv. 15), +2 Talent Levels (up to Lv. 15).
E6 | Fate in the Sea of Stars
Characters with Military Merit gain +20% All-Type RES PEN.
After they attack, Cerydra deals Wind Additional DMG equal to 360% of her ATK, up to 20 times. This counter resets upon using her Ultimate.
If any ally has Military Merit, Cerydra herself gains +20% RES PEN.
Additional DMG is not counted as a standard attack—ideal for triggering non-combat-based effects.
This final Eidolon makes her the core of a burst engine, applying consistent passive damage and debuff penetration that scales with any offensive lineup.
▍Conclusion
Cerydra is a standout unit not because she heals or shields, but because she controls the tempo of the entire battlefield. From granting stat buffs, removing debuffs, enabling bonus skills, and stacking conditional burst damage, she defines a new generation of versatile Abundance characters.
At lower Eidolons, she is already a powerful tactical support. At higher Eidolons, she evolves into a true secondary DPS, rivaling even primary damage dealers when correctly supported.
Whether you're a strategist who enjoys synergy and rotation control, or a high-level player seeking meta-shaping potential, Cerydra will be your queen on the galactic chessboard.
