Cerydra is a Wind Harmony support who specialises in Skill-based damage dealers. She grants one ally "Military Merit", a large ATK buff that scales on her own ATK, then upgrades it to "Peerage" once she has 6 Charge: the ally's next Skill gets huge CRIT DMG and RES PEN and is cast a second time for free through Coup de Main. She is at her best with Phainon and Anaxa.

Teams
Recommended teams
Phainon hypercarry
Her best synergy: she duplicates Phainon's Foundation: Stardeath Verdict at full power without spending Scourge, while Sunday speeds up his Coreflame and Dan Heng keeps him shielded.
Sustainless Phainon
Cyrene's Ode to Law adds 30% CRIT DMG to the Military Merit holder and refunds a Charge after each Coup de Main.
Archer
Archer's Skill spam builds her Charge extremely fast, and she can even be played SP-positive here.
Guide
How to play
How she works
- Military Merit (Talent). The ally with Military Merit gains ATK equal to 24% of Cerydra's ATK, and each of their attacks triggers a Wind Additional DMG hit from Cerydra (up to 20 times, reset by her Ultimate). Military Merit only stays on the last target: switching targets resets her Charge to 0.
- Charge. She gains 1 Charge when using her Skill, 2 with her Ultimate, and 1 whenever the Military Merit holder uses a Basic ATK or Skill (not during Coup de Main).
- Peerage (6 Charge). Military Merit is upgraded: the holder's Skill DMG gets +72% CRIT DMG, they gain 10% All-Type RES PEN, and their next Skill on enemies triggers Coup de Main, repeating the Skill. Afterwards, 6 Charge is consumed and Peerage reverts to Military Merit.
- Traces. A2 turns every 100 ATK above 2,000 into +18% CRIT DMG (max at 4,000 ATK), A4 gives +100% CRIT Rate, and A6 gives +20 SPD to her and her target for 3 turns whenever she uses her Skill, plus 5 Energy each time the target uses a Basic ATK or Skill.
Rotation
- Use her Technique on the field and switch to your DPS before combat: they get Military Merit, and she casts a free Skill on them at the start of the fight.
- Skill your DPS to build Charge; their own Basic ATKs and Skills add more.
- At 6 Charge, time Peerage so that it lands on your DPS's strongest Skill (Phainon's Foundation: Stardeath Verdict, Anaxa's Skill).
- Use her Ultimate for 2 quick Charges and some AoE damage.
Tips
- Never move Military Merit to another ally: all Charge is lost.
- Aim for 4,000 ATK: it maxes her A2, and her ATK buff scales with it.
- She is Skill Point-hungry when you spam her Skill; SP-positive teammates help a lot.
Strengths
- Excellent buffs for Skill-based damage dealers
- Lets an ally use two fully powered Skills in a row
- Passive ATK buff and extra Additional DMG on every attack of her target
- Flat SPD boost for herself and her target, and good Energy economy
- Powerful E1, especially with Phainon
Weaknesses
- Her biggest buffs only apply to Skill DMG, limiting her to a few carries
- Low personal damage
- Usually Skill Point-negative in her best setups
Notable dupes · Eidolon
E1
Big upgrade
16% DEF ignore for her target (36% on Skills during Peerage), and her Skill gives 2 Energy — which means 2 Coreflame per Skill for Phainon. The best stopping point for Phainon players.
E2
Optional
+40% DMG for her target and more personal damage; mostly a stepping stone towards E6.
E6
Solid upgrade
+20% All-Type RES PEN for her and her target, and her Additional DMG becomes significant enough to play her as a sub-DPS.
