Cerydra Guide and Best Builds

Home/Honkai: Star Rail/Cerydra

Cerydra is a 5★ Wind Character following the Path of Harmony. Cerydra is a unique support that causes your Main DPS's Skill to repeat itself.
Our Cerydra Build Guide will show you the best Lightcones, Relics and Team Compositions to build the best Cerydra you can.

Cerydra's Best Light Cone

Epoch Etched in Golden Blood
S1

Increases the wearer's ATK by 64.0 / 80.0 / 96.0 / 112.0 / 128.0%. After using Ultimate to attack, recovers 1 Skill Point(s). After the wearer uses their Skill on one ally character, increases the Skill DMG dealt by the target by 54.0 / 67.5 / 81.0 / 94.5 / 108.0% for 3 turn(s).

Sources: Event Warp (limited)

This is Cerydra's Signature 5★ Lightcone and it is her best option. This Lightcone provides the most ATK of any Harmony Lightcone which buffs Cerydra's strongest buff from her Talent Ave Imperator. Additionally, this Lightcone provides a significant boost to Skill DMG done on your Main DPS. The Skill Point generated by this Lightcone helps make rotations more fluid.

Flowing Nightglow
S1

Every time an ally attacks, the wearer gains 1 stack of Cantillation. Each stack of Cantillation increases the wearer's Energy Regeneration Rate by 3.0 / 3.5 / 4.0 / 4.5 / 5.0%, stacking up to 5 time(s). When the wearer uses their Ultimate, removes Cantillation and gains Cadenza. Cadenza increases the Wearer's ATK by 48.0 / 60.0 / 72.0 / 84.0 / 96.0% and increases all allies' DMG dealt by 24.0 / 28.0 / 32.0 / 36.0 / 40.0%, lasting for 1 turn(s).

Sources: Event Warp (limited)

This is 's Signature 5★ Lightcone and it is a competitive option for Cerydra in teams. In other teams you will not be able effectively to take advantage of the 1 turn buffs provided by this Lightcone and would be better off with another option.

A Grounded Ascent
S1

After the wearer uses Skill or Ultimate on one ally character, the wearer regenerates 6 / 6.5 / 7 / 7.5 / 8 Energy and the ability's target receives 1 stack of "Hymn" for 3 turn(s), stacking up to 3 time(s). Each stack of "Hymn" increases its holder's DMG dealt by 15.0 / 17.3 / 19.5 / 21.8 / 24.0%. After every 2 instance(s) of Skill or Ultimate the wearer uses on one ally character, recovers 1 Skill Point.

Sources: Event Warp (limited)

This is 's Signature 5★ Lightcone. This Lightcone provides a large DMG boost for your main DPS while generating Energy for Cerydra. This is weaker than above options due to the need to constantly recast Cerydra's Skill to obtain stacks but the Skill Points generated helps mitigate the Skill Point cost of doing so.

Dance! Dance! Dance!
S5

When the wearer uses their Ultimate, all allies' actions are Advanced Forward by 16.0 / 18.0 / 20.0 / 22.0 / 24.0%.

Sources: Stellar Warp

This is a 4★ Limited Lightcone and is the best 4★ Lightcone for Cerydra. The Action Advance from this Lightcone can result in significantly more actions by all of your allies which makes up for the lower ATK provided by this Lightcone.

The Forever Victual
S5

Increases the wearer's ATK by 16.0 / 20.0 / 24.0 / 28.0 / 32.0%. After the wearer uses Skill, increases ATK by 8.0 / 10.0 / 12.0 / 14.0 / 16.0%, stacking up to 3 times.

Sources: Mission Reward

This is a 4★ Lightcone that from the The Chrysos Maze Grand Resturant event. This Lightcone provides a massive amount of ATK which will in turn buff your main DPS via Cerydra's Talent Ave Imperator and should be the best option if you do not have a 5★ Lightcone or a S5 .

But the Battle Isn't Over
S1

Increases the wearer's Energy Regeneration Rate by 10.0 / 12.0 / 14.0 / 16.0 / 18.0% and regenerates 1 Skill Point when the wearer uses their Ultimate on an ally. This effect can be triggered once after every 2 uses of the wearer's Ultimate. When the wearer uses their Skill, the next ally taking action (except the wearer) deals 30.0 / 35.0 / 40.0 / 45.0 / 50.0% more DMG for 1 turn(s).

This 5★ Lightcone is a viable option for teams as he can take advantage of the 1 Turn damage boost. In other teams Cerydra will not necessarily use her Skill every turn so the uptime may be limited. Cerydra will not be able to get the Skill Point from this Lightcone but will benefit from the Energy Regeneration Rate.

Past and Future
S5

When the wearer uses their Skill, the next ally taking action (except the wearer) deals 16.0 / 20.0 / 24.0 / 28.0 / 32.0% increased DMG for 1 turn(s).

Sources: Echo of War, Forgotten Hall Store, Mission Reward

This is a 4★ Limited Lightcone that is a weaker version of since it does not provide Energy Regeneration Rate.

Best Relics and Planar Ornaments for Cerydra

Best Relics for Cerydra

These are the best Relic Sets to build for Cerydra. These relics are listed in order of overall strength for the team taking into account offensive power for the team.

Sacerdos' Relived Ordeal

2-Piece Set: Increases SPD by 6.0%.

4-Piece Set: When using Skill or Ultimate on one ally target, increases the ability target's CRIT DMG by 18.0%, lasting for 2 turn(s). This effect can stack up to 2 time(s).

This is Cerydra's best Relic Set to build. This Relic set provides Cerydra with SPD which will make reaching SPD Breakpoints easier while providing a large CRIT DMG % bonus to your Main DPS which is a significant DPS gain. In teams that need Skill Points it may be better to build 2pc-2pc with SPD % or ATK % sets as you will not maintain both stacks if you use your Skill every 3 turns.

Sacerdos' Relived Ordeal

Hero of Triumphant Song

2-Piece Set: Increases SPD by 6.0%.

4-Piece Set: When using Skill or Ultimate on one ally target, increases the ability target's CRIT DMG by 18.0%, lasting for 2 turn(s). This effect can stack up to 2 time(s).

2-Piece Set: Increases ATK by 12.0%.

4-Piece Set: While the wearer's memosprite is on the field, increases the wearer's SPD by 6.0%. When the wearer's memosprite attacks, increases the wearer's and memosprite's CRIT DMG by 30.0%, lasting for 2 turn(s).

If you do not have a good 4PC Sacerdos Set you can opt to use 2pc-2pc instead. Ideally you would use at least one 6% SPD relic and either another 6% SPD relic or a 12% ATK relic. You could also use 2 12% ATK relics. These are the 6% SPD Relic Sets obtainable:

Warrior Goddess of Sun and Thunder
Messenger Traversing Hackerspace
Sacerdos' Relived Ordeal

These are the 12% ATK options currently available:

Musketeer of Wild Wheat
Prisoner in Deep Confinement
The Wind-Soaring Valorous
Hero of Triumphant Song

Best Planar Ornaments

Lushaka, the Sunken Seas

2-Piece Set: Increases the wearer's Energy Regeneration Rate by 5.0%. If the wearer is not the first character in the team lineup, then increases the ATK of the first character in the team lineup by 12.0%.

This is Cerydra's best-in-slot Planar Ornament. This provides 12% ATK for your Main DPS and 5% Energy Regeneration Rate for Cerydra.

Penacony, Land of the Dreams

2-Piece Set: Increases wearer's Energy Regeneration Rate by 5.0%. Increases DMG by 10.0% for all other allies that are of the same Type as the wearer.

This is viable Planar Ornament for Cerydra in teams as Anaxa is a Wind Carry and will benefit from the DMG%. We suggest building over this as it is more universally useful.

Broken Keel

2-Piece Set: Increases the wearer's Effect RES by 10.0%. When the wearer's Effect RES is at 30.0% or higher, all allies' CRIT DMG increases by 10.0%.

This is a weaker alternative choice for Cerydra's as it does not grant any Energy Regeneration Rate but still is a potent DPS increase for CRIT Main DPS.

Cerydra Build Comments

Character Explanation Build Advice

Character Explanation

Cerydra is a Harmony support that grants allows for a unit to have a repeat Skill cast with her skill Pawn's Promotion. Her skill will grant one character the Military Merit buff which can gain charge from a variety of sources.

Cerydra's Technique First-Move Advantage will track the active character out of combat and cast Cerydra's Skill on the last character to be active when Combat Starts. This cast will not cost Skill Points but is otherwise completely normal and will give Energy.

The sources of charge are:

1 Point of Charge every time Cerydra uses her Skill Pawn's Promotion
2 Point of Charge every time Cerydra uses her Ultimate Scholar's Mate
1 Point of Charge every time the unit with Military Might uses a Basic ATK or Skill.
1 Point of Charge the first time a character with Military Might uses their Ultimate per Battle from her A4 Trace Vidi

At 6 charge the buff will upgrade to Peerage which grants all effects of Military Merit in addition to a large Skill CRIT DMG and RES PEN boost. When a character with Peerage uses their Skill it will repeat twice and consume 6 points of charge. This will initially do the Coup de Main repeat which will not consume resources like Skill Points but will use one time buff effects followed by the normal Skill cast of the character which will consume resources.

Cerydra will also grant the character with Military Might a portion of her ATK with her talent Ave Imperator. Additionally, Cerydra's A2 Trace Vici will grant 20 SPD to herself and the character with Military Might.

Build Advice

We suggest building 160 SPD or higher as this will give an extra action within 250 AV (2 turns). Having high SPD is important to make it easier to maintain her buffs and to build charge quicker. Reaching 160 SPD is very easy as she gives herself 20 SPD. With SPD boots and one 6% SPD 2pc she will be ~149 SPD so it will only take 4 to 5 SPD rolls to reach the breakpoint.

After reaching the SPD breakpoint we suggest stacking as much ATK% on gear as possible as this is her most effective stat for DPS. ATK% will boost both Cerydra's damage and the damage of the character with Military Might while CRIT DMG would only boost Cerydra's damage. Additionally, Cerydra already has a very high amount of CRIT DMG due to her A6 trace Veni which devalues any further investment.

Cerydra's Best Teams

Cerydra Teams

Cerydra's Best Eidolons

Cerydra's Eidolons are quite weak but her first Eidolon is notably powerful in Phainon teams where it can be up to a 30% team DPS increase. We suggest stopping after her first or second Eidolon as further investment is incredibly inefficient. We also strongly suggest investing in Eidolons for Phainon first as his 2nd Eidolon is more impactful than all of Cerydra's Eidolons combined. With Anaxa both of his first two Eidolons are stronger than Cerydra's.
Listed below are our calculations for Cerydra's Eidolons.

Eidolon	% Diff	% Diff E0	Comment
Seize the Crowns of All	16%	16%	This Eidolon is stronger on Phainon since it generates Coreflames for him.
Forge the Dreams of Many	12%	29.9%	Eidolon 2 brings Cerydra in line with E0 Harmony units for weaker team compositions like The Herta.
Torch the Laws of Old	0.9%	31%	Very Weak Eidolon as Basic ATK and Skill scale poorly with levels.
Remake the Realms of Men	4%	36.3%	Doubles the damage of her Ultimate.
Help and Hurt Repaid in Full	4%	41.8%	Cerydra's Talent is a significant portion of her damage contribution and scales well with levels.
A Journey Set Starward	25%	77.2%	Most of the value of this Eidolon comes from the RES PEN.
