Hey guys,

I m a bit confused. Can anyone tell me the differences between Surveillance and Retrieval? Which of them gives me a higher chance of finding rare items?

Surveillance affects the rarity of the item you're collecting - there are different thresholds for the type of items a certain rating will bring (common, uncommon, rare, etc) - this is the stat you want to prioritize if you're looking for otters or like colossus slabs, kamacite.

Retreival just affects the amount of items you're bringing back.

Thanks for clarifying. Is there a guide how much surveillance I need for certain items?

After nearly a month of data collecting, here's the info I have on the dreaded "CSCFIFFE" ("Current sub condition found insufficient for further exploration") message we sometimes get on our second anomaly. All this data was taken from trips straight to DSS7 and back. Raw data is up on my Google sheet.

Total runs counted: 227
Total CSCFIFFE: 92
Percentage: 41%
Otters: 7

CSCFIFFE frequency by build
Total CUUC trips: 120
Total CSCFIFFE, CUUC: 48
Percentage: 40%
Otters: 3

Total trips, CUSC: 68
Total CSCFIFFE: 28
Percentage: 41%
Otters: 2

Total trips, CYYC: 33
CSCFIFFE: 13
Percentage: 39%
Otters: 2

CSCFIFFE percentage by first weather encountered
Strong currents on first anomaly total: 68
Strong currents followed by CSCFIFFE: 26
Percentage: 38%

Volcanic total: 109
Volcanic then CSCFIFFE: 45
Percentage: 41%

Clear and Calm total: 50
Clear and Calm then CSCFIFFE: 42%


CSCFIFFE by repair level

Total trips starting fully repaired: 72
CSCFIFFE: 31
Percentage: 43%

Total trips starting with wear: 155
CSCFIFFE: 61
Percentage: 39%

The takeaway here seems to be that the chance of getting CSCFIFFE on the second anomaly of Deep Sea Site 7 is a FLAT 40% NO MATTER WHAT YOU DO. Thanks for nothing, Square.

Looking at just the return on Abroader Otters, my subs found a total of 454 anomalies, of which 92 were CSCFIFFE on the second try. That means my subs got 362 chances to roll on otters, of which 7 were successful, for an overall drop chance of 2% per anomaly. I got 50 "Clear & Calm" weather results on the first anomaly (22%), and 21 "Clear and Calm" on the second anomaly (9%), for a total of 71 "Clear & Calm" results on all attempts (16% of total.) Of the 50 Clear & Calm results on the first anomaly, six produced otters, for a drop rate of 12%, and for the 21 Clear & Calm on the second anomaly, 1 produced an otter, a 5% drop rate. The overall drop rate from all Clear & Calm weathers was 10%.

Overall conclusion: the drop rate on Abroader Otters is terrible and there's not much we can do about it.

There's only one more thing I'm considering checking but it's probably a wild goose chase. I was wondering if the flat 40% rate is locked to some specific ship part. All my three test builds had Coel Hulls and Coel Bridges. I did a quick search on the sub builder tool and there's only one build with the necessary minimum stats (Surv. 145 and Favor 105) that doesn't use these two parts, and it's the UUUY build. I'm considering converting a couple subs to UUUY and/or CUUY just to see if there's ANYTHING that can be done to make that flat 40% failure rate budge, but I don't have very high hopes.

I have looked all over, but I cannot find a solid answer on my own....
What would be a good to great end game 4 sub build? I currently have a CUWC and SSSS. I'd like to at least hit the otters and/or kamacite. What would be a good plan to make the parts for the later subs?
It's mostly me doing it, so I'd like to refrain from too many overlapping parts.

I'd suggest the CUSC build if you're trying to economize. (S = Shark) You can put it together from the parts you already have and it will be capable of bringing back both otters and kamacite.

Ok, so. I see that 130 surv is needed for kamacite and below and 145 for otters. However, just a few posts before said that CCWC (130 surv) is enough to get otters. Am I missing something?

As an answer to my own question. It seems that a fleet will be mostly CCXC (x=anything, really), so dynamic parts will not be a thing like in airships. Anything not that will have too low of retrieval or speed, so it will take forever or not get enough of anything to make the trip worth it, or both.
Is a fleet like this good?:

CCWC

i'm not sure i'm going to bother with trying for any kamacite. just got my 3rd otter to sell mmmm gillll lol

We finally managed to get an otter with a 170 surveillance sub with 105 favor. Now I'm trying to figure out how to upgrade our 3 other subs, because all of them have low stats and keep bringing back garbage that doesn't have much value, which makes sending them out pointless. Our second sub has Syldra-C-C-Shark, which nets us 130 retrieval, but it would need more surveillance.

Do I have to fix the submarines every time before I send them out? Even though they are only used once and have only a little bit worn out. The reason is that even if it is 99% good condition, the mission sometimes still says due to the condition the second roll will not happen. If I have to fix them every single time, then the consumption of the dark matter materials will be very high. Or is the unable to have the second roll due to the condition of the submarines completely RNG?
