Yo, Star Rail fam! If you’re searching for “Castorice Guide in Honkai: Star Rail” or asking, “How to build Castorice in Honkai: Star Rail?”—you’re in for a treat! Castorice just dropped as the second Remembrance DPS after Acheron, and HSR really made her a beast while keeping her super F2P-friendly.

in this Castorice Guide in Honkai: Star Rail, I’ll break down her kit, best builds, team comps, and showcase her power in Memory of Chaos. Whether you’re a free-to-play player or a whale, this guide will help you unleash her dragon’s full potential. Let’s jump into the Castorice Guide in Honkai: Star Rail and make her your new main DPS!
Why Is Castorice So Strong in Honkai: Star Rail?

Castorice is all about HP mechanics, and her kit revolves around her massive dragon, Netherwing, that wreaks havoc on enemies. According to this Castorice Guide in Honkai: Star Rail, any HP change—whether it’s yours, your allies’, or your summons’—fuels her ultimate. When Netherwing’s HP hits zero, it leaves the battlefield with a huge AoE boom, healing your team in the process.
Then, once her ultimate gauge hits 100%, you can summon Netherwing back to spit fire on everyone. Her global passive also prevents an ally from dying once per battle (with some caveats), making her a lifesaver in tough fights. Search “Castorice Guide in Honkai: Star Rail” to learn more!

How Does Castorice’s Kit Work in Honkai: Star Rail?
Let’s break down her mechanics in this Castorice Guide in Honkai: Star Rail. Castorice’s unique territory, Last Netherland, activates when you use her technique before battle, giving a stunning intro animation and a -20% attack debuff to enemies. Netherwing deals massive AoE damage but sacrifices its own HP over time. Here’s the cycle:

- HP Dance: As your team loses HP, Netherwing gains HP. When Netherwing dies at 1% HP, it triggers a final explosion, heals your team, and resets the cycle.
- Ultimate: Her ultimate gauge fills based on HP changes (capped at 34,000 HP). At 100%, summon Netherwing again for a three-turn rampage.
- Skill: Her skill consumes allies’ HP to charge her ultimate faster. Without Netherwing, it’s a blast attack; with Netherwing, it’s an enhanced AoE attack. It’s SP-neutral, so you can spam it without worry.
- Passive: Her global passive lets allies enter a “Moon Cuckoo” state when they die, giving you a chance to heal or shield them to revive.
What Are the Best Builds for Castorice in Honkai: Star Rail?
In this Castorice Guide in Honkai: Star Rail, let’s talk builds. Castorice scales off HP and thrives on Memo Sprite damage, so here’s how to gear her:

- Light Cone: Her signature Light Cone is ideal, offering HP, AoE%, and 33% DEF ignore. F2P options include the 4-star “Battle Pass” Light Cone for decent HP or even Bailu’s Abundance Light Cone (just for the HP stat—ignore the passive).
- Relics: Go for the 4-piece Poet set for 32% HP and speed debuffs. Alternatives include 2-piece Longevous Disciple (HP) + 2-piece Scholar (Crit Rate).
- Planar Ornaments: Use Bones set for HP% and Crit Damage tailored for Memo Sprites. Prioritize HP% on body, boots, and rope—skip energy or speed since her ultimate cycles fast.
- Stats Priority: Focus on HP (main stat), Crit Rate, Crit Damage, and Quantum DMG. Her traces already give 18.7% Crit Rate, 13.3% Crit DMG, and 14.4% Quantum DMG.
What Are the Best Team Comps for Castorice in Honkai: Star Rail?
Castorice shines with F2P-friendly teams, as highlighted in this Castorice Guide in Honkai: Star Rail. Her design revolves around taking and healing damage to cycle Netherwing faster:

- Core Team (F2P): Castorice + Gallagher (healer) + Ruan Mei (support) + Trailblazer (flex). Gallagher’s indirect healing pairs perfectly with Castorice’s HP-draining kit, while Ruan Mei boosts damage and HP bar generation.
- Premium Option: Swap Trailblazer for Firefly for extra chip damage and debuffs.
- Alternative F2P Support: Pela is a solid choice for DEF shred and ultimate spam, especially with Gallagher or Huo Huo as healers.
How Does Castorice Perform in Memory of Chaos?

I tested Castorice in Memory of Chaos for this Castorice Guide in Honkai: Star Rail, and she’s a beast! With an F2P team (Castorice, Gallagher, Pela, Trailblazer), she cleared waves in 4 cycles, dealing up to 1.7M damage with Netherwing’s final boom. With a premium team (swapping Pela for Firefly), she zero-cycled the first wave and hit 1.8M on single-target enemies. Her AoE is insane, but single-target damage relies on Netherwing’s final explosion. Check “Castorice Guide in Honkai: Star Rail” for more gameplay tips!
Should You Pull for Castorice in Honkai: Star Rail?

Here’s the big question in our Castorice Guide in Honkai: Star Rail: is she worth pulling? Absolutely, especially for F2P players! She’s low-investment, doesn’t need premium 5-star supports, and her animations are some of the flashiest in HSR. However, as a DPS, she might not age as well as supports, so ensure you can invest in her Light Cone (or use the Battle Pass one). Her F2P-friendly kit, balanced AoE/single-target damage, and dragon-summoning vibes make her a fun and powerful pick.
