Cerydra
Yes—Cerydra is a strong Wind Harmony. Ultimate “Scholar's Mate” hits every enemy on the field in one cast. Best with Phainon / Anaxa / Sunday. Amplifies Skill-focused carries. Skip when you already staff both sides with Sunday/Robin/Sparkle.
Cerydra is a 5★ Wind Harmony Support. Skill “Pawn's Promotion” is the primary in-combat spend. Ultimate “Scholar's Mate” is the payoff window for damage or team utility. This Phase 1 page covers kit text, gear targets, and pull notes—team comps stay empty until Phase 2.

Strengths
- Ultimate “Scholar's Mate” hits every enemy on the field in one cast—time it for the carry’s damage window instead of casting on cooldown out of habit.
- Skill “Pawn's Promotion” buffs allies’ damage for a short window—this is the spend that keeps the rotation honest.
- Talent “Ave Imperator” The character with "Military Merit" increases ATK by an amount equal to 27.0% of Cerydra's ATK—miss the stack conditions and the burst window feels empty.
- Learning when to hold vs spend “Pawn's Promotion” is the difference between a clean Cerydra cycle and a wasted Skill Point.
Weaknesses
- Buff windows on “Scholar's Mate” are short—casting them when the carry cannot attack wastes the CRIT DMG/ATK amp for a full cycle.
- Cerydra’s Skill is often the expensive part of the rotation; SP-negative teams force Basic ATKs and you lose the advance/amp that made the unit worth playing.
- Spamming “Pawn's Promotion” every turn without watching Skill Points strands the rest of the team—Cerydra is often the SP sink.
- If “Scholar's Mate” is still offline at the end of a MoC cycle, the build is usually Energy/ERR or rotation order—not a missing CRIT roll.
Trace Priority
Pawn's Promotion carries most of the kit’s damage or utility—level this first.
Scholar's Mate supports the main rotation—raise after the top priority traces.
Ave Imperator supports the main rotation—raise after the top priority traces.
King's Castling is last priority outside of filling trace materials.
Stat Priority
Open with Technique if it helps, spend Skill to advance the kit’s resource, and hold Ultimate for the damage or buff window. Exact teammate order lands in Phase 2.
Open supports first, then spend the carry’s Skill/Ult inside the buff window. Exact order varies by the team tab above.
Light Cones
5★ · Path cone
Increases the wearer's ATK by 0.64%. 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 #4[f1]% for 3 turn(s).
Why it works —Signature / best-in-slot when owned—passive lines up with Cerydra’s kit triggers.
5★ · Path cone
Increases the wearer's Energy Regeneration Rate by 0.1% 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 0.3% more DMG for 1 turn(s).
Why it works —Flexible alternative on the same path—equip if you already own it at higher superimposition.
4★ · Path cone
At the start of the battle and whenever the wearer's turn begins, one of the following effects is applied randomly: All allies' ATK increases by 0.1%, all allies' CRIT DMG increases by 0.12%, or all allies' Energy Regeneration Rate increases by 0.06%. The applied effect cannot be identical to the last effect applied, and will replace the previous effect. The applied effect will be removed when the wearer has been knocked down. Effects of the same type cannot be stacked.
Why it works —Best accessible option for most accounts—raise superimposition when copies drop.
4★ · Path cone
When the wearer uses their Skill, the next ally taking action (except the wearer) deals 0.16% increased DMG for 1 turn(s).
Why it works —Budget path cone—fine while building the account.
Relics
Team Compositions
Cerydra enabling Phainon. Phainon, Sunday, Dan Heng · PT complete the hypercarry shell.
Phainon is the damage seat in this shell — build the supports around their rotation, not the reverse.
Enabler / amp piece this page is built around — keep their buffs or debuffs online every cycle.
Sunday is the Advance / DMG amp — time their Skill/Ult for the carry’s damage window.
Dan Heng · PT shields the hypercarry and softens MoC / AS chip so glass DPS can commit to Skill spam.
