Who is Cerydra?

Cerydra, the Iron Tamer of Tides, is a 5-star Wind Harmony character who specializes in buffing allies who primarily deal damage through their Skills. As the Chrysos Heir who wields the Coreflame of "Law," her kit revolves around granting the "Military Merit" buff to a single ally, which can be upgraded to "Peerage" when fully charged.

What makes Cerydra particularly powerful is her Talent "Ave Imperator," which allows the character with "Military Merit" to duplicate their Skill once when it's used. This effectively doubles the Skill usage for characters who rely on Skill damage, making her an exceptional support for specific DPS units.

Is Cerydra Worth Pulling in 2025?

The answer largely depends on your roster. W Cerydra truly shines when paired with DPS characters whose damage primarily comes from their Skills. If you have Phainon, Anaxa, or Feixiao, then Cerydra becomes an incredibly valuable addition to your team.

However, if your main DPS characters rely on Basic Attacks or Ultimates for damage, you might want to consider other support options. E0S1 Cerydra (meaning Eidolon 0, Superimposition 1 Light Cone) is sufficient for most content, though her first Eidolon provides a significant boost by allowing the buffed character to ignore 16% of enemy DEF.

Best Cerydra Build

For optimal performance, Cerydra's relic setup should focus on maximizing her ATK stat and providing utility:

  • 4-piece Sacerdos' Relived Ordeal: Provides CRIT DMG buff to the ally with Military Merit

  • Alternative: 4-piece Eagle of Twilight Line for faster rotation and energy regeneration

Best Ornament Sets

  • Lushaka, the Sunken Seas: Provides Energy Regen and ATK buff to the first character

  • Penacony, Land of the Dreams: Excellent choice when paired with Wind DPS units

Main Stats Priority

  • Body: ATK%

  • Feet: SPD

  • Sphere: ATK%

  • Rope: ATK% or Energy Regen

Substats Focus

  • SPD (aim for 140 base to reach 160 in combat)

  • ATK% and flat ATK (target at least 4000 ATK)

  • CRIT DMG

  • Energy Regen

Best Light Cones for Cerydra

  1. Epoch Etched in Golden Blood (5★): Her signature Light Cone, providing ATK buff and Skill DMG boost

  2. Flowing Nightglow (5★): Great alternative for Energy Regen and ATK boost

  3. A Grounded Ascent (5★): Strong option for Energy Regen and DMG buff

  4. The Forever Victual (4★): Best 4-star option, providing an ATK buff

  5. Planetary Rendezvous (4★): Good when paired with Wind DPS

Best Teams for Cerydra

Cerydra's team compositions should center around DPS units that primarily use their Skills for damage. Here are some optimal team setups:

Premium Team

  • Cerydra + Phainon + Sunday + Huohuo

This team maximizes Phainon's Skill damage while providing turn advancement through Sunday and healing/ATK buffing through Huohuo.

F2P Friendly Team

  • Cerydra + Dan Heng + Remembrance Trailblazer + Lynx

A more accessible team that still leverages Cerydra's Skill duplication with Dan Heng as the main DPS.

Alternative DPS Options

  • Anaxa: Benefits greatly from Cerydra's buffs as his damage comes mostly from his Skill

  • Feixiao: Cerydra helps her use her Skill twice, generating more Flying Aureus stacks

Trace Priority

When upgrading Cerydra's Traces, follow this priority order:

  1. Skill: Most important for the Skill DMG buff

  2. Talent: Critical for the ATK buff

  3. Ultimate: Helps with overall damage and Charge generation

  4. Basic Attack: Lowest priority

Her Bonus Abilities are also important, particularly:

  • Veni: Increases CRIT DMG based on ATK

  • Vici: Increases SPD and provides Energy regeneration

Gameplay Tips for Honkai Star Rail Cerydra

  1. Manage Charge carefully: Cerydra gains Charge when the buffed ally uses Basic ATK or Skill, and when she uses her Ultimate.

  2. Technique usage: Her Technique grants Military Merit to the character who triggers battle, allowing for a strong opening.

  3. Rotation optimization: Ideally, use Cerydra's Skill on your main DPS, build up Charge to upgrade to Peerage, then have your DPS use their Skill to trigger the duplication effect.

  4. Energy management: With E1, Cerydra regenerates Energy for the ally when using her Skill, which is particularly valuable for energy-hungry DPS units like Phainon.

Final Verdict

Cerydra honkai has established herself as a specialized support that can dramatically increase the damage output of Skill-focused DPS units. While not universally applicable to all team compositions, in the right setup, she can enable some of the highest damage ceilings in the game.

If you have Phainon, Anaxa, or Feixiao, Cerydra is almost certainly worth adding to your roster. Her ability to double Skill usage creates a unique advantage that few other supports can match in 2025's meta.

Whether you're running an E0S1 Cerydra or investing in higher Eidolons, she remains one of the most impactful Harmony characters for specific team compositions in Honkai Star Rail.

Remember that the perfect build ultimately depends on your available resources and team composition, so adapt these recommendations to best fit your specific needs and playstyle.
