What's the best Castorice build?

What are the best teams for Castorice in Honkai Star Rail?

In all of her teams, Castorice acts as a hypercarry DPS. Thanks to Cyrene's bonuses, she works fantastically in a team filled with other Chrysos Heirs, but you can achieve a similar effect for much cheaper using the Trailblazer, Lynx, and Pela. If you really want to show the enemy who's boss, you can run Castorice in a double-DPS team with Mydei.

Here are Castorice's best teams:

What are the best light cones for Castorice?

The best light cone for Castorice is Make Farewells More Beautiful, which is her signature five-star light cone. As it's her signature cone, it's tailored specifically towards her kit, but it can be a bit of a pain to get your hands on.

Unfortunately, the Remembrace path is severely lacking in F2P-friendly five-star light cones, so The Flower Remembers is your next best option.

Here are the best light cones for Castorice:

• Make Farewells More Beautiful - limited five-star
• The Flower Remembers - four-star
• Sweat Now, Cry Less - four-star

What are the best relics and planar ornaments for Castorice?

The best relic set for Castorice is Poet of Mourning Collapse, with two Bone Collection's Serene Demesne planar ornaments.

We recommend a full set of Poet of Mourning Collapse to take advantage of its quantum damage and crit-boosting effects. If you're struggling to farm a good set, pairing Scholar Lost in Erudition with Longevous Disciple is a useful stopgap measure, boosting Castorice's crit rate and max HP.

Bone Collection's Serene Demesne is perfect for Castorice as it boosts her max HP, which is critical given how her kit interacts with health, and buffs her memosprite's crit damage. If you're running a memosprite-heavy team, Arcadia of Woven Dreams might be a better choice.

These are the best relics for Castorice:

• Poet of Mourning Collapse
• Scholar Lost in Erudition + Longevous Disciple

These are the best planar ornament sets for Castorice:

• Bone Collection's Serene Demesne
• Arcadia of Woven Dreams

When picking each piece of equipment, prioritize options with the following stats as main and sub-stat options:

• Crit rate
• Crit damage
• HP%
• Speed

What are Castorice's priority skills?

Practically every part of Castorice's kit is essential aside from her basic attack, so upgrade her ultimate, talent, and skill equally if you can.

Here's Castorice's skill priority:

• Ultimate = Talent = Skill > Basic attack

Who are Castorice's voice actors?

Here are the actors who voice Castorice in Honkai Star Rail:

• English - Melody Muze
