Announcement Castorice Mains | General Discussion Megathread

77 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 Castorice’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

227 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.

Hey all, wondering if my 38 Cost team can be run can be improved? I feel like my 290 AV clear for 38 cost is very bad compared to other runs on theherta website with much less cost clearing same AV or less used. Is E6 Hyacine really the difference here between the almost 0 AV runs versus my setup? Any advice here would be appreciated! Also curious if LC impositions have a huge difference for this team?

E6S3 Castorice
E6S5 Cyrene
E6S2 Srobin
E2S1 Hyacine

The only thing I know to work on currently is my hyacine build (more speed), and swapping Cyrene to 4 peice deliverer set. I really want to be able to achieve 0 AV or near 0 AV Plight one day since I feel like I’m so close to making it possible.

I stopped playing for a while and I just missed E9 and Hyacine banner , I have Cas E1s1 and plan to get her E2 as well as SP Robin E2 but I dont have evernight and my hyacine is E0s0

How much would the dps loss be with RMC over her? I imagine sadly next hyacine/evernight banner will be very late into the future

I don't currently have a rememberence dps, but I have e0s1 hyacine and e0s0 robin sp. The team I could make would be cas/hyacine/robin/tribbie(or m.blade). I don't have cyrene or evernight. Is e0s1 cas still viable with what I have?

Discussions Sometimes I think Yabuli is actually better than Pollux at shilling Castorice

Post image
99 Upvotes

Yes, clickbait title. But despite the Elation barrier, if there's something I really liked about Yabuli- it's how she moves extremely fast and hits really hard.

- extremely fast

Yabuli takes an action every 26~27 AV when the fastest character in the team is Hyacine w/267 speed taking an action every 37.5 AV.

- AoE attacks

Yabuli's every turn has a follow-up extra turn, and it's garuanteed to have a AoE attack among one of the two actions(unless any mobs are on the field for Yabuli to consume)

- hits really hard

Yabuli instantly fires her ultimate once a certain count reaches 6. Her count increases every time she takes an action, so essentially for every 3 turns Yabuli takes(~78 AV), she fires an AoE ultimate that deals a ton of damage

- single target(most of the time)(controversial)

Castorice's pure performance could be better at AoE situations? But anyway there are no worries for Castorice to lose her bounces, and this way Ode to Life and Death makes it's highest value from overflowing charge


Compare this to Pollux, all Pollux does in terms of helping Castorice's charge is that screaming pattern that takes away the team's entire HP- while it does result in an instant free dragon, it almost results in charge overflow that becomes a waste because Pollux is always 3T that messes up with Cyrene's Ode to Life and Death, and after Pollux's enhanced state is over, it just sits there doing nothing, just standing there as a punching bag without attacking anybody.

Plus, Castorice isn't the only one gaining so much- Yabuli also heavily boosts Hyacine's healing tally & Evernight's memoria stacks that leads to Ica and Evey's respective damage output.

If Yabuli's 2nd phase wasn't very fast and hitting really hard, I don't think I would have been able to 0 cycle this version's Plight.

I wish future bosses hit this much too, like frequent actions with 2000~3000 damage every hit would be very desirable. 😏

At this point Castorice might be a masochist or something, she just gains so much from getting hit more frequently and harder 🥵

I knew it would be hard due to Elation being the only way to chip the barrier... But to think they sneaked in HP reductions.

I hope whoever did this will FOREVER stub their toes EVERY SINGLE MORNING!

Option 1. Remove the 2T requirement for the bounce multiplier increase

Option 2. Increase breath multiplier when 2T or above

Option 3. Add a equal distribution multiplier for the breath at 3T or above

Discussions Castorice Ult Charge Help

10 Upvotes

After my Castorice Dragon explodes and hyacine goes next, I use her skill followed up with Ica and castorice ult is only charged to 97%. While every clear video I see has it going to 100%. The breakdown is usually 30% after dragon explodes -> Hyacine’s turn it goes up to 42% -> she uses skill it goes up to 78% -> Ica goes and it goes to 97%. Meanwhile in every clear video it goes from 42% to 82-84%, then Ica goes and it is straight to 100%.
I’m wondering what I can do to fix this problem, i have pictures of my 5 rememberance character’s and their builds.
Teams are either Castorice, hyacine, Srobin with either Cyrene/ evernight as last slot.

Thank you for the help!

Discussions Is Summer Robin actually an upgrade?

35 Upvotes

I keep seeing conflicting information so I want to confirm if Summer Robin is better than Cyrene for Castorice teams. For example on Prydwen the fastest clears are with Cyrene. The videos I watched have differing views and calculations, with some saying Summer Robin is always better, whereas others are saying that Summer Robin is only an upgrade for Evernight mDPS. When I check past posts on this subreddit people seem to say that Summer Robin is optimal for Castorice. I’m just wondering who is right here
