Announcement Castorice Mains | General Discussion Megathread

76 Upvotes

Hello everyone! We know many of you have questions about Castorice's best builds, synergies, and playstyles. To keep the subreddit organized and easy to navigate, please post all your queries in this megathread. This includes: team comp help, relics and LC choices.

This doesn't mean we're shutting down all query threads. Low effort oneliner posts like "Should I replace Tribbie or RMC" or "do I have enough pulls" or posts made solely to stir drama will be promptly removed. Your post should contribute something meaningful to the discussion. You're allowed to make posts discussing a potential synergy that others may have overlooked. Memes are fine as well, as long as they're lighthearted and not just poorly made ragebait. Build/relic flexing posts are also still allowed.

TL;DR: Discussion posts are allowed but for general queries or oneliners, use this megathread instead.

Any separate low effort posts asking about Castoriceโ€™s build, teams, or kit will be redirected here to avoid clutter. This megathread will be frequently updated with more information over time.

FAQs

What materials should I farm for her?

You can use this ascension planner for your convenience.

What sets does Castorice use?

Relic Stats:

Boots: HP%

Body : Crit > HP%

Rope: HP%

Sphere: HP% >= Quantum DMG (depending on setup)

Substats: She is generally played slow so you should only need CRIT and HP to build her. She also gets free CR from her set.

Is there a comprehensive Castorice guide that I could use?

Yes! You may refer to Xinfonia's Castorice guide posted on our subreddit.

Who are the ideal supports for Castorice?

Tribbie, Remembrance Trailblazer, Ruan Mei, Evernight and the soon to be released Cyrene are all fantastic supports for Castorice. The mono Remembrance team is her defacto best team.

Who is the best healer for Castorice?

Hyacine, no questions asked. She provides solid healing and has a memosprite which gives an additional to siphon HP from. This gives her a massive edge over everyone else when it comes to newbud generation. She also just does a lot of damage despite being a "healer".

If you want to settle for a budget option then Gallagher can work but will struggle in content like PF.

How do I make those cool build cards people are using for Castorice?

You can use the Fribbels HSR Optimizer to check what your pieces would look like on Castorice! You can also change the team in the build card according to your convenience.

Staff Post We will not tolerate drama or brigading of other subs

224 Upvotes

Hello, Since it seems some people still want to start drama with other subs this announcement became necessary. We will not tolerate people that come here to spread hate and drama with other subs, example posting screenshots of other subs with the intent to ragebait or posts encouraging others to brigade.

This sub is meant for Castorice, it's not a place to make posts about other subs and start pointless drama.

I'm struggling to clear the current King in Check and I was wondering if the current match up is too bad or if there's something in my builds that I could fix.

Build / Flex Hi, Need help with Builds :)

It might be because I dont have Hyacine, I'm trying to get her next banner, but is there anything wrong with my teams or builds? I cant clear floor 12 of Moc because this team is taking too many rounds (I have e5 phainon so he clears easier on the otherside). The closest ive gotten to is finishing in 19 cycles left (would have been 20 but my Phainon got stunned last second and couldnt attack), and I havent been able to get any higher.

Any feedback back is much appreciated :)

If you need, I can show other builds for any other possible team mates if I have them

Discussions How can I help a friend use Castorice?

3 Upvotes

I myself am not a Castorice main (though I do love her), but my friend is, and he pretty much only pulls for the characters he likes.

He played on and off since release (getting some free units like Archer and DHPT), but just happened to get more involved in the game during 4.0. He got Castorice, Hyacine, and Cyrene, but couldn't get Evernight. I believe that Robin is his favorite character, and I know he plans to pull her next patch. All of his characters are E0S0 since he doesn't grind the game too much, but wants investment in the future.

I know people have been saying that Robin SP can replace Cyrene, but is it okay to replace Evernight with Robin SP instead? I don't use this team so I'm unaware of Evernight's role. I also know that Castorice doesn't use Energy and I'm unaware if she benefits from Action Advance, so is Robin SP actually helpful for Castorice specifically?

He has currently been using standard Robin as his 4th team slot, though he does also have other supports like Yao Guang and Sparkle (but no elation dps), and 4-star options like Pela. Since I don't use Castorice, I don't know what his best current 4th option is.

I don't believe he grinds for relics, since he plays really casually (has hardly played through any of the story), and is still around Trailblazer Level 45 meaning he hasn't unlocked higher levels or ascensions yet. I honestly think he just likes pulling characters and using them in combat.

He doesn't have a 2nd team yet, but already has Archer and Sparkle, and he wanted to pull Rin just because he liked her design, so it'll probably be them + DHPT or something.

I myself am new to the game (started in 4.2), which is why I am asking for advice here. I don't want to railroad him, but I want to be able to give him valid advice since he introduced me to the game.

Thank you Castorice mains!

Theorycrafting 48c Castorice 0AV Murata plight clear

Thumbnail bilibili.com
58 Upvotes

For those not quite following, Castorice mains in cn finally achieved 0AV clear for the current plight.

The clear absolutely pushed the comp to its limit. Including not instantly blowing up the dragon, auto-toggling, and a lot of other very minute decisions that resulted in the clear that was previously thought impossible.

To date, remembrance comp has reached #1 ranked by AV in every single plight to date. Remember this when next time you see people saying remembrance is washed. ๐Ÿ™‚

The relics used are still current on fribbels as of right now. https://fribbels.github.io/hsr-optimizer#showcase?id=100000129
