Cerydra is a new character in Honkai: Star Rail, coming later during Version 3.5. She is a 5-star Wind element character playing the role of Support on the “Harmony” path. She supports her allies by triggering an extra turn for them after their action, enabling them to deal increased damage. Her abilities are especially effective for single-target damage dealers who depend on Action Gauge mechanics.
What Abilities and Skills Does Cerydra Use?
Abilities:
Military Merit – Gain increased ATK = 24% of Cerydra’s ATK
- Basic Attack (Maneuver: Expeditious Relocation): Deals Wind damage to a single target.
- Skill (Ascend: From Pawn to Queen): Grants an ally Military Merit, building Cerydra’s Charge to 8. At 6 Charge, the ally gains Nobility, removing crowd control, boosts Skill CRIT DMG by 72%, and causes their next skill to trigger twice via Coup de Main. After use, 6 Charge is consumed, reverting Nobility back to Military Merit.
- Ultimate (All is Chess, Checkmate in Four): Deals 240% Wind DMG to all enemies and gains 2 Charge. If no one has Military Merit, it’s granted to the first character in the team lineup.
- Technique (First-Move Advantage): Aquires Military Merit, which transfers to the next active character when switched. In the following battle, the character holding Military Merit will automatically use their Skill once at the start without using any Skill Points.
