Honkai Star Rail: Cerydra Build Guide, Traces, Relics & Synergy

First came the blade, now comes the brain.  Cerydra, Imperator of the Northern Empire and demigod of Law, has arrived. Though she has been hidden through most of Version 3, the time has come for her to take an active role.  The question is, will her grand schemes be enough to save the day?

How Does Cerydra Work

Cerydra is a 5-Star Wind Harmony unit who focuses on Buffing 1 character only.

A Multi-Step Plan

Cerydra’s gameplay is all about getting Charge.  She gets 1 point of Charge when she uses her Skill on an ally, 2 points when she uses her Ultimate, and 1 point when the target of her Skill uses either her Basic Attack or Skill.  When she has 6 points of Charge, the Buff she gives the target of her Skill is immediately upgraded.

In its base form, Cerydra’s Skill Buffs her target’s ATK based on a percentage of Cerydra’s own ATK.  Furthermore, when said target uses their Basic Attack or Skill, she will deal 1 instance of Additional DMG.  This effect can occur 20 times, with the count resetting after she uses her Ultimate.

In its upgrade form, her Skill retrains all the effects of its lesser form, while also increasing the CRTI DMG of the target’s Skill, increasing their All-Type RES PEN, and providing them the “Coup de Main” Buff.  The next time the target uses their Skill, “Coup de Main” will copy and immediately use the Skill (before the target’s actual Skill is unleashed).  After “Coup de Main” ends, 6 points of Charge are consumed, and the Buff returns to its lesser form.
