Cyrene Overview: Role and Meta Position in Star Rail 3.7

Let's be honest here—Cyrene isn't just another support character. She's what happens when HoYoverse decides to completely rewrite the rules of team synergy. This premium 5-star Ice Remembrance support has earned her SS-tier rating for good reason, and after spending weeks testing her in endgame content, I can confidently say she's a game-changer.

Her kit does something fascinating: it empowers Chrysos Heirs teammates while providing universal damage amplification through Zone mechanics and True Damage scaling. That's a mouthful, but stick with me—it gets better.

At level 80, you're looking at 1397 HP, 446 ATK, 582 DEF, and 101 SPD base stats. Nothing groundbreaking there. But her mechanics? That's where things get spicy. She offers special Ode buffs specifically for Chrysos Heirs, Zone deployment that converts ally damage to True Damage (completely bypassing DEF—yes, you read that right), and an Ultimate battery that fully charges all teammates' Ultimates on first activation.

Here's the catch though. Cyrene absolutely requires at least two Chrysos Heirs for efficient Recollection charging. Without proper Heir support, her effectiveness drops off a cliff. I learned this the hard way during my initial testing phase.

Her Ultimate Verse • Vow ∞ consumes 24 Recollection points and summons a Demiurge memosprite with HP at 100% of Cyrene's Max HP plus 12-24% bonus.

Meanwhile, her Skill Bloom, Elysium of Beyond generates 3 Recollection points while deploying a 2-turn Zone that deals 12-26% of allies' original damage as True Damage per instance.

The Talent system is equally impressive—granting 10-22% team damage increase through a Future stack system that converts to Recollection points. In my testing, properly built teams consistently experience 30-40% damage increases, with E2 configurations enabling 0-cycle potential in Memory of Chaos.

Her Enhanced Basic Attack becomes AoE Ice damage dealing 15-33% Max HP twice while generating 3 Recollection points. For optimal progression and Stellar Jade acquisition, Honkai Star Rail top up through BitTopup offers competitive pricing and instant delivery.

Core Build Requirements: 180+ Speed Threshold

Now here's where most players mess up—they completely ignore the 180+ speed threshold. This isn't just a nice-to-have stat; it's absolutely crucial for unlocking Causality in Trichotomy bonus trace.

What does this give you? A flat 20% team damage increase plus 2% Ice RES penetration per excess speed point, capping at 60 points maximum. Do the math—that's potentially 120% additional Ice RES penetration at 240 speed. Insane.
