Best Light Cones for Castorice in Honkai Star Rail

Sweat Now, Cry Less (Image via Sportskeeda Gaming || HoYoverse)

You can only equip Remembrance Light Cones on Castorice. Here are some LCs that you can use on this newly released character:

• Make Farewells More Beautiful
• Sweat Now, Cry Less
• Victory In a Blink

Since Castorice doesn’t have many free-to-play Light Cone options in version 3.2, we recommend pulling for Make Farewells More Beautiful. It can boost her maximum HP, advance her turn when Netherwing disappears, and grant a whopping 30% DEF ignore.

The second-strongest Light Cone for Castorice is Sweat Now, Cry Less. The Superimposition 5 version of the LC is extremely effective on the character. However, since the gear has only been out for two updates, it's not possible to get the S5 variant. S1 will work just fine until you get four more copies of the LC.

If you don't have the aforementioned Light Cones, you can equip Victory in a Blink on Castorice. While the LC is free-to-play, it only grants a flat 12% CRIT DMG at Superimposition 1 (24% at Superimposition 5).

Best Relics for Castorice in Honkai Star Rail

Best Relic sets

Since Castorice wields the Quantum element and is a DPS unit, you must farm Relic sets that suit her.

Here are some Relic sets that you should farm for Castorice in HSR:

• 4-piece Poet of Mourning Collapse
• 2-piece Scholar Lost in Erudition + 2-piece Longevous Disciple

In version 3.2, the 4-piece Poet of Mourning Collapse is the best Relic set you can farm for Castorice. It can boost the 5-star unit’s outgoing Quantum damage and CRIT Rate.

However, to get the extra CRIT Rate, Castorice’s SPD needs to be lower than 110. Since this set also affects her memosprite, it can consistently hit CRITs while attacking adversaries.

Farming for a perfect 4-piece relic set can take a while, so you can use the 2-piece Scholar Lost in Erudition + 2-piece Longevous Disciple sets as alternatives. Although this combination won't be as effective as the 4-piece Poet of Mourning Collapse, it will allow Castorice to deal a decent amount of damage.

Best Planar Ornament sets

As for Castoice’s Planar Ornament sets, you can farm for the following:

• Bone Collector’s Serene Demesne
• Rutilant Arena

Like Poet of Mourning Collapse, Cone Collector’s Serene Demesne is the best Planar Ornament set for Castorice. It passively boosts her maximum HP by a decent amount. Moreover, the character and her memosprite receive a significant CRIT DMG boost when the former’s HP is higher than 5000.

As an alternative, you can use the Rutilant Arena Planar Ornament set. While the CRIT Rate buff is passive, Castorice won’t be able to utilize the set properly.
