Maximizing the potential of Castorice in Honkai: Star Rail involves a strategic focus on her Ascension and Trace materials. As a 5-star Quantum character following the Path of the Remembrance, Castorice enhances your team’s damage output, making her a valuable asset in difficult encounters. Previously an NPC since Version 3.0, she became a playable character in Version 3.2, introducing her compelling damage mechanics through her unique kit.
Central to Castorice’s abilities is HP-draining gameplay. Her Skill targets enemies while simultaneously siphoning HP from her allies. Once a set threshold has been reached, she can unleash her Ultimate to summon the Netherwing, a memosprite that inflicts substantial damage at its own HP expense. Moreover, Castorice and Netherwing can perform coordinated attacks, and the latter offers protective capabilities to allies. Impressively, she possesses a powerful ability enabling the revival of fallen teammates, even when she is not in the active roster.
Essential Ascension Materials for Castorice in Honkai: Star Rail
Engage in Calyx (Golden) Activities on Amphoreus
To fully harness Castorice’s base efficacy, ascending her to level 80 is imperative. Start farming for crucial materials such as Ethereal Omen, Echoing Wail, and Eternal Lament, all of which drop from Black Tide Creatures. It’s advisable to tackle Calyx (Golden) challenges on Amphoreus, where you can gather not only these essential materials but also Credits and Character EXP items like Traveler’s Guide.
Given that these materials are categorized under the same item family, utilize the Omni-Synthesizer to upgrade lower-tier Ethereal Omens into Echoing Wails, and subsequently into Eternal Lament.
Below is a summary of the materials needed for Castorice’s Ascension, delineated by level milestones:

Another critical item required for Castorice’s Ascension is Darkveil Moonlight. This particular Ascension item is obtainable exclusively by defeating the Stagnant Shadow: Shape of Gelidmoon, which is located in the Murmuring Woods area of the Grove of Epiphany on Amphoreus. A total of 65 Darkveil Moonlight materials are needed, requiring 13 encounters at the maximum level, with each challenge consuming 30 Trailblaze Power—a total of 390 Trailblaze Power is necessary. It’s worth mentioning that these materials are also used for the character Tribbie in Honkai: Star Rail.
In addition, you will need a cumulative total of 308,000 Credits to reach all Ascension tiers, plus an estimated 508,000 Credits to enhance Castorice with Character EXP materials. If you find yourself short on Credits, consider farming at Calyx (Golden): Bud of Treasures on Amphoreus, as this will provide both the required currency and Ethereal Omens, which are essential for both Castorice’s Ascension and her Trace-leveling in Honkai: Star Rail.
Required Materials for Castorice’s Traces (Abilities) in Honkai: Star Rail
Farming Remembrance Trace Materials Can Be Time-Consuming
As highlighted earlier, Castorice’s Trace enhancements also rely on Ethereal Omen, Echoing Wail, and Eternal Lament. Prior to Version 3.2, these items could only be farmed through Calyx (Golden) activities, but that limitation has changed. You can also acquire extra copies from the Embers Exchange shop. Keep in mind that the demand for these materials increases for Castorice’s Trace upgrades, so consistently farm while utilizing the Omni-Synthesizer in Honkai: Star Rail to meet her requirements.
Below is a comprehensive list of materials needed to fully upgrade all of Castorice’s Traces and unlock her entire skill tree:

The remaining materials for Castorice’s Traces include Bīja of Consciousness, Seedling of Manas, and Flower of Ālaya. These materials, exclusive to Remembrance, can be farmed at the Calyx (Crimson): Bud of Remembrance activity located within the Strife Ruins in Castrum Kremnos on Amphoreus. Due to the substantial quantities required, you may find yourself engaged in prolonged farming sessions over several days or even weeks. Additionally, remember to utilize the Omni-Synthesizer to optimize your material supply. If you’ve previously farmed materials for the Remembrance Trailblazer or Aglaea, you may find some items still on hand.
Bīja of Consciousness and Seedling of Manas can also be acquired in limited amounts from the Embers Exchange shop on a monthly basis. Furthermore, as you progress to higher Trace levels, you will need Auspice Sliver, a weekly boss material that drops from defeating the Shadow of Feixiao in the Echo of War: Inner Beast’s Battlefield, situated on the Xianzhou Luofu’s Skysplitter map. Though only 12 copies are necessary, the weekly limits on boss encounters imply you may require patience before you can farm this material effectively.
Additionally, Tracks of Destiny is another rare material essential for advanced Traces. You can obtain it weekly from the Simulated Universe and various reputation systems. It is also awarded during specific events and battle passes, with the option to buy more via Embers Exchange each month and at the Starlight Exchange.
Ultimately, the entire process to level Castorice’s Traces will demand about 3,000,000 Credits. When combined with Ascension costs, this total can be quite significant, necessitating frequent farming for Credits, ideally through Calyx (Golden): Bud of Treasures on Amphoreus. Acquiring all materials to maximize Castorice, while taking time and effort, is essential for establishing her as a premier DPS character in Honkai: Star Rail.
