If you’re searching for the ultimate Hyacine Build Honkai Star Rail, you’ve come to the right place. Hyacine stands out as a 5-star healer with both high-speed HP-sacrifice healing and AoE damage in Honkai: Star Rail. This guide will help you create the best Hyacine Build Honkai Star Rail by showing you the right relics, light cones, team comps, and how to make the most of her kit.

Why Choose Hyacine in Honkai: Star Rail?

Hyacine is designed for fast-paced teams that rely on constant healing and frequent HP sacrifices. Thanks to her memosprite Little Ica, she heals allies automatically every time they take damage and returns the favor with AoE damage scaled from her total healing output. Her kit shines in:

• High-Speed Healing: Boost Hyacine’s SPD to improve healing, damage, and Max HP boosts for the entire team.
• AoE Damage: Her memosprite deals AoE damage each turn, stacking up to 240% bonus damage with consistent healing triggers. Her A2 trace also provides 100% CRIT Rate, making relic building easier.
• Team Flexibility: Fits easily into HP-scaling teams, and her Ultimate boosts survivability for all.

Hyacine Trace Priority: Where to Invest First

For maximum value, unlock Hyacine’s major traces first:

1. Gloomy Grin (Major Trace 1): +100% CRIT Rate and improved healing for low HP allies.
2. Stormy Caress (Major Trace 2): +50% Effect RES and self-debuff removal on Skill/Ultimate.
3. Tempestuous Halt (Major Trace 3): Reaching over 200 SPD gives more Max HP and increased outgoing healing per excess SPD.

Best Hyacine Team Comps

Castorice Team

• Main DPS: Castorice
• Supports: Tribbie, Remembrance MC, or Ruan Mei
• Sustain: Hyacine

This team thrives on HP-synergy—Castorice’s HP-consuming skill triggers Hyacine’s heals, which in turn ramps up Castorice’s special energy. The result is non-stop heals and powerful AoE output.

Mydei Team

• Main DPS: Mydei
• Supports: Tribbie, Remembrance MC, or Sunday
• Sustain: Hyacine

Here, Mydei consumes his own HP, and Hyacine’s constant healing keeps him in the fight. While her raw healing isn’t as high as some supports, she adds meaningful damage and utility.

Hyacine Build Tips & Key Strengths

• Trigger Automatic Healing: Hyacine’s unique trait heals allies every time they take damage, perfect for aggressive or self-damaging teams.
• Stack Damage Boosts: Her healing directly increases her AoE damage, reaching up to 240% bonus.
• Simplified Relic Building: The 100% CRIT Rate from A2 lets you focus on SPD and HP% without worrying about CRIT rolls.
• Team Survivability: Her Ultimate boosts Max HP, giving HP-scaling characters both survivability and increased DPS.

Final Thoughts: Is Hyacine Worth Building?

Hyacine is a versatile support who stands out for her ability to both heal and deal meaningful AoE damage. Built with high SPD and the right relics, she excels in HP-sacrifice and damage-focused teams, especially with Castorice or Mydei. Her blend of sustain and offensive capability means you never have to sacrifice damage for healing.
