Completing the Ultimate Hyacine Build: Light Cones, Relics, and Teams in Honkai: Star Rail

Select Language:

If you’ve been enjoying Honkai: Star Rail for a bit, you may have noticed how simple it is to swap out a DPS character when dealing with enemy weaknesses. However, when it comes to sustainers, it’s a different story. These characters are versatile and fit easily into any team’s fourth slot.

Hyacine, though categorized as a Remembrance character, functions similarly to other sustainers. She can consistently heal her team and cleanse their debuffs, making her one of the more straightforward characters to build.

Top Light Cones for Hyacine

Once you acquire Hyacine from her limited-time banner, your first move should be to equip her with an appropriate light cone. Make sure to access the light cone menu in her character screen and remember, it’s crucial to use a Remembrance cone since she won’t benefit from the passive effects of cones from other paths.

As you would expect from a rare five-star character, Hyacine’s best light cone is her signature, Long May Rainbows Adorn the Sky. If you don’t have that one, there are some free-to-play friendly alternatives:

Long May Rainbows Adorn the Sky	This light cone significantly boosts her SPD, allowing her to exceed the 200 SPD threshold. It also lets Hyacine consume a bit of ally HP to enhance the damage dealt by Ica’s skill. Additionally, after Ica attacks, enemies sustain 18 percent increased damage from all allies.
Memory’s Curtain Never Falls	This light cone offers less than her signature, but still provides decent buffs. Using it, Hyacine can gain up to 12 percent extra SPD. After employing her Skill, her allies can inflict 16 percent more damage on enemies.
Victory In a Blink	This cone also grants a 16 percent damage boost to Hyacine’s allies while providing her with an impressive 24 percent Crit DMG. Given Ica’s 100 percent Crit Rate, this synergy works perfectly.

Best Relics and Planar Ornaments for Hyacine

Daily gameplay revolves around farming relics and planar ornaments for your characters in Honkai: Star Rail. You can achieve this by spending your Trailblaze Power in Caverns of Corrosion or taking part in Ornament Extraction. Keep in mind that each relic set’s main and sub-stats are randomized.

For Hyacine, focus on farming the Warrior Goddess of Sun and Thunder for relics and Giant Tree of Rapt Brooding for planar ornaments. While these should be your endgame options, there are alternatives if you’re just starting out:

Ranking Hyacine’s Relics

Rank	Name	Synergy With Hyacine
1	Warrior Goddess of Sun and Thunder	This relic set pairs well with Hyacine, granting her up to 12 percent extra SPD and 15 percent Crit DMG when healing allies. The Crit DMG buff also benefits Hyacine, amplifying Ica’s damage.

Synergy With Hyacine

Warrior Goddess of Sun and Thunder

This relic set pairs well with Hyacine, granting her up to 12 percent extra SPD and 15 percent Crit DMG when healing allies.

The Crit DMG buff also benefits Hyacine, amplifying Ica’s damage.

Messenger Traversing Hackerspace

This set does not provide Crit DMG but gives Hyacine up to 18 percent SPD and grants allies an extra 12 percent SPD.

Though it may not benefit Hyacine’s allies as much, the increased SPD enhances her healing output.

Two pieces of either above

If you lack better stats on either set, you can simply use two pieces from any sets that offer an SPD bonus.

Ranking Hyacine’s Planar Ornaments

Rank	Name	Synergy With Hyacine
1	Giant Tree of Rapt Brooding	This ornament boosts Hyacine’s SPD by 6 percent and provides a 20 percent increase in Outgoing Healing if her SPD exceeds 180, which is essential for her.
2	Broken Keel	Hyacine’s 50 percent Effect RES from her Stormy Caress ability lets her equip this ornament set effectively to enhance her allies’ Crit DMG.
3	Bone Collection’s Serene Demesne	If you have Hyacine’s signature weapon and want to amplify her damage further, this set can provide extra HP and Crit DMG.

Hyacine’s Stat Priorities

Body	Outgoing Healing Boost
Feet	SPD
Sphere	HP Percent
Rope	Energy Regeneration Rate
Sub-Stats	SPD > HP Percent > Crit DMG

Hyacine should maintain over 200 SPD as a minimum, and it’s crucial to stack as much Crit DMG and HP as possible.

Optimal Team Synergies for Hyacine

Best Hyacine Team	Hyacine, Castorice, Remembrance Trailblazer, Tribbie
Hyacine Double DPS Team	Hyacine, Castorice, Mydei, Remembrance Trailblazer
Hyacine General Team	Hyacine, DPS, Sub-DPS/Support, Support

Hyacine boosts her allies’ max HP, making her an excellent fit for HP-based characters like Castorice and Mydei. She works particularly well with Castorice since Ica offers consistent healing, enhancing Castorice’s Ultimate energy gain.

If you have Hyacine’s light cone, the HP consumption from all allies also enhances Castorice’s ultimate. Combining these two characters allows for the effective use of Castorice’s dragon right from the first turn.

Apart from a hypercarry setup for Castorice, consider pairing Hyacine in a dual-DPS format with both Castorice and Mydei. Remembrance Trailblazer or Tribbie can serve as great supports, with the former providing a True DMG buff for Castorice. Mydei is capable of dealing over 200,000 damage even without substantial buffs.

Lastly, Hyacine can be included in nearly any team as a sustain character, as her healing remains valuable even if the increased max HP isn’t beneficial. However, if you have other integral sustainers like Lingsha for break teams, they might be the better choice.

Overview and Trace Priorities for Hyacine

	Rarity	Five-Star
	Path	Remembrance
	Combat Type	Wind
	Overworld Rating	S+ Tier
	Memory of Chaos Rating	S+ Tier
	Pure Fiction Rating	S+ Tier
	Apocalyptic Shadow Rating	S+ Tier

Hyacine’s high ratings are no surprise, considering her role as a flexible sustainer. She can fit into nearly any team and excels in all endgame modes due to her AoE damage from Ica. As a Remembrance character, she has additional abilities in her memosprite that you should upgrade for optimal performance.

Her skill set, while enhanced by those abilities, remains fairly straightforward:

Both Hyacine’s Skill and Ultimate heal all allies and Ica, with the Ultimate increasing the max HP of allies for three turns. These moves also cleanse debuffs from allies, and the Ultimate grants her the After Rain effect.
With the After Rain effect, Ica can hit every enemy with a 100 percent Crit Rate attack immediately after her turn. The damage of this attack increases by 40 percent, stacking up to three times whenever Hyacine or Ica heals allies.
Ica is immune to crowd control, and when an ally takes damage, he heals them at the start of the next turn. If this happens while Hyacine has the After Rain effect, he can heal the entire team for the same amount.
Ica restores 15 energy to Hyacine upon being summoned, plus an additional 15 for the first summon. Furthermore, when he leaves the battlefield, he advances Hyacine’s turn by 30 percent.
Both Hyacine and Ica enjoy a 100 percent Crit Rate and gain increased Outgoing Healing if the target’s HP is at or below 50 percent.
If Hyacine has 200 SPD, both she and Ica’s max HP will increase by 20 percent. Any SPD above 200, up to 400, grants her an extra one percent Outgoing Healing for each SPD point.

It’s clear that maximizing Hyacine’s SPD and Energy Regeneration Rate is essential for optimizing her kit.

Hyacine Trace Priority

When upgrading Hyacine’s traces, prioritize her Skill or Ultimate first, as they are essential to her performance. Once those are enhanced, focus on Ica’s Memoprise Skill, followed by Hyacine’s talent, and lastly, Ica’s talent. Her normal attack can be left as is since it won’t be utilized much in battle.
