Overview

"'Flamebearer,' 'Tyrant,' 'Empress,' 'Supreme Commander,' 'Imperator'... The world has given me countless titles, but you may simply call me by my true name — Cerydra."

"Chessmaster Monarch" Cerydra

In the lost dynasty of the Northern Empire, frozen lands burn with dreams of conquest. Sovereign Cerydra, the Chrysos Heir wielding the Coreflame of "Law," sets her pieces, challenges the gods, judges the faithless, and carves the path of Flame-Chase into the world’s fate.

"This is no end. The path of Amphoreus shall blaze across the stars!"

Rarity: ⭐⭐⭐⭐⭐ | Combat Path: Harmony | Combat Type: Wind

Cerydra is a 5-star Wind Harmony character designed as a single-target support, particularly for characters like Phainon. She provides buffs, extra actions via Coup de Main, and is a top-tier support for skill-focused DPS.

Cerydra Kit

Basic Attack

King's Castling

Deals Wind DMG equal to 100% of Cerydra’s ATK to a single enemy.

Skill

Pawn's Promotion

Grants "Military Merit" to one ally and adds 1 Charge point to Cerydra (max 8 points). At 6 Charge points, "Military Merit" upgrades to "Peerage," dispelling Crowd Control debuffs. Allies with "Peerage" get a 72% CRIT DMG boost for Skill DMG, 10% All-Type RES PEN, and trigger Coup de Main when using their Skill on enemies. After Coup de Main, 6 Charge points are consumed, and "Peerage" reverts to "Military Merit."

Crowd Control Debuffs: Freeze, Entanglement, Imprisonment, Dominated, Outrage, Strong Reverberation, Alien Dream, Snarelock, Terrified.

Coup de Main: Duplicates and instantly uses the ally’s Skill, then uses the original. Does not trigger another Coup de Main.

Cerydra excels as a support for Phainon but also synergizes well with Anaxa for double Skill usage and follow-ups.

Ultimate

Cerydra Ultimate

Scholar's Mate

Gains 2 Charge points and deals Wind DMG equal to 240% of Cerydra’s ATK to all enemies. If no ally has "Military Merit," grants it to the ally in the first team slot.

Talent

Ave Imperator

Allies with "Military Merit" gain an ATK boost equal to 24% of Cerydra’s ATK. When they use Basic Attack or Skill, Cerydra gains 1 Charge point (not during Coup de Main). After their attack, Cerydra deals additional Wind DMG equal to 60% of her ATK (up to 20 times, resets on Ultimate). "Military Merit" affects only the latest target; switching resets Charge to 0.
