Cyrene Character Overview

Cyrene is an Ice-element support who excels at boosting allies’ offensive capabilities. She can bless a chosen ally, granting them additional damage potential. When her blessing targets a Chrysos Heir character, it activates a unique effect; otherwise, the chosen ally’s DMG is increased by 40% for two turns. This makes her one of the most flexible support options available for different team compositions.

Her Ultimate is a centerpiece of her kit. It summons a memosprite that instantly takes an extra turn and activates all allies’ Ultimates at once. Cyrene then enters a special state that enhances her Basic Attack while both she and her memosprite gain a 50% CRIT Rate boost — transforming her from a pure support into a hybrid support-damage dealer during battle.

Cyrene Basic Information

• Rarity: 5★
• Path: The Remembrance
• Element: Ice
• Role: Support / Hybrid DPS

Cyrene’s Abilities and Playstyle

Cyrene’s abilities and playstyle in Honkai: Star Rail revolve around balancing offense and support through her unique “Recollection” mechanic. She empowers allies with powerful buffs, summons a memosprite companion for additional effects, and transforms into a potent hybrid support-damage dealer when her Ultimate is active.

Basic Attack – Look, The Beginning of Hope!

Cyrene gains 1 Recollection point and deals Ice DMG equal to 50% of her Max HP to one enemy.

Enhanced Basic Attack – Towards Love and Tomorrow

When empowered, her Basic Attack grants 3 Recollection points, dealing Ice DMG to a single target and then AoE Ice DMG to all enemies. However, this version does not recover Skill Points.

Skill – Bloom, Elysium of Afterlife

Cyrene creates a Zone lasting for two turns. While active, each instance of damage dealt by allies triggers additional True DMG equal to 20% of the original damage. This Zone disappears if Cyrene is knocked down. The Skill synergizes best in teams with multi-hit or follow-up attacks.

Ultimate – The Poetry’s, The Promise’s

Her Ultimate summons a memosprite that acts immediately, activating all teammates’ Ultimates simultaneously. Cyrene then enters the “Ripples of Past Reverie” state, enhancing her Basic Attack and boosting both her and the memosprite’s CRIT Rate by 50%. The Zone effect from her Skill is also deployed indefinitely. This Ultimate can only be used once per battle, so timing is crucial.

Talent – Wishes, Flow Like Melodies

Whenever Cyrene or her allies act, they interact with the “Future” and “Recollection” mechanics. When she gathers 24 Recollection points, her Ultimate becomes available. Additionally, while Cyrene is active, the entire team’s DMG dealt increases by 20%.

Technique – At West Wind’s End, Eternal Tranquility

Using her Technique creates a dimension for 30 seconds, increasing movement speed for allies by 50%. Entering combat within the duration automatically triggers her Zone effect from the Skill.

Cyrene Memosprite System

Her memosprite is an essential part of her kit — acting as both an independent damage source and a support enhancer.

• Waltz of Flowers and Arrows: Deals AoE Ice DMG based on the memosprite’s Max HP.
• This Poem, A Benediction to Life: Buffs one ally; if they are not a Chrysos Heir, their DMG dealt increases by 40% for 2 turns.
• Unique Odes: Each Ode provides synergy when the memosprite interacts with different characters such as Dan Heng, Anaxa, Aglaea, or Hyacine — enhancing CRIT stats, SPD, or triggering bonus effects.

Cyrene Light Cone Recommendation

This Love, Forever (5★)

• Stats: HP 1270 | ATK 476 | DEF 463
• Effect: Increases SPD by up to 30%. When the memosprite uses a skill on allies or enemies, it triggers “Blank” and “Verse” effects that boost team CRIT DMG and enemy DMG taken. When both are active, their power increases by 120%.

This Light Cone is designed specifically for Cyrene, optimizing her buffing and support potential through synergy with her memosprite.

Best Team Composition for Cyrene

Cyrene fits perfectly in Ice-oriented or Remembrance-path teams. Her ideal teammates include:

• Chrysos Heir characters – benefit from exclusive buffs tied to her abilities.
• Follow-up attackers – like Clara or Dr. Ratio, who can take advantage of her True DMG Zone.
• Fast supports – such as Sparkle or Bronya, who can help Cyrene build Recollection faster.

Cyrene’s Stat Priorities

When building Cyrene, focus on:

• HP% (scales her DMG and memosprite power)
• SPD (activates her passive bonuses and enables faster energy gain)
• CRIT DMG / CRIT Rate (for enhanced offensive potential during her Ultimate state)

Recommended Planar and Relic Sets:

• Hunter of Glacial Forest (Ice DMG, CRIT DMG)
• Messenger Traversing Hackerspace (SPD and team buff potential)

Cyrene Bonus Abilities

1. Pure Child of Remembrance: When an ally’s memosprite is summoned, it gains “Future.”
2. Traveler of Time: Grants Cyrene additional Recollection points based on the number of Chrysos Heir or Remembrance allies.
3. The Triad of Causality: If her SPD reaches 180+, allies’ DMG increases by 20%, and her Ice RES PEN scales with excess SPD.

Cyrene Eidolons

1. Blank, Where The Poem Begins: When her Ultimate or memosprite is used, it gains Story points and can perform an extra AoE attack.
2. Thirteen Hues of Radiance: Starts battle with more Recollection and strengthens the Zone’s True DMG effect.
3. Because of You, As I’ve Written: Boosts Ultimate and Basic ATK levels.
4. Pen the Next Page, With a Smile: Enhances the memosprite’s damage multiplier in battle.
5. Gaze, Fill the Flowers of Yesterday: Increases Skill and Talent levels.
6. Memories, Turn Into Ripples ♪: When her Ultimate is activated, all allies’ actions advance by 100%. Subsequent memosprite triggers grant allies RES PEN and extra turns.

Optimal Cyrene Play Strategy

To maximize her potential:

1. Build SPD and HP. These stats fuel her support buffs and overall damage output.
2. Time her Ultimate wisely. Since it can only be used once per battle, activate it when allies have their Ultimates ready.
3. Pair with CRIT-heavy allies. Her buffs amplify CRIT Rate and CRIT DMG, allowing burst rotations.

Cyrene brings a refreshing twist to support gameplay in Honkai: Star Rail. Her flexible buffing, teamwide CRIT boosts, and unique memosprite mechanics make her a high-value addition to many team compositions. With the right build and timing, Cyrene can turn an ordinary setup into a symphony of powerful, coordinated attacks.
