I have been lurking about results from places like DS7 and such to get the otter and kamacite farming. Kind of unsure what build(s) I should upgrade to to farm otter/kamacite/wax, well when wanting to focus on one. All four are 50, but one set sits with full shark, two with full Unkiu. The only good one is a CCWC with 130 surv, 95 retrieval, 80 speed, 70 range, 115 favor. I have mats to make 4 Syldra parts, and was planning on CCSyC (150/65/80/90/140) but felt 65 retrieval would make for poor kamacite farming (but good for say, otter). Is there a well-rounded build I could go for? Could just upgrade 2 submarines with 2 Syldra parts instead of all four with one I guess. Know it's hard to say for certainty since a lot is just theorycrafting still.

You could try CSySySy
Sur 160
Ret 100
Spe 40
Ran 95
Fav 130

Like Alien_gamer mentioned before, the CSySySy fit is the alternative to the CCSyC fit that's been mentioned before. It trades half of its Speed for a relatively decent boost to its Retrieval and a couple points in Range (helping with a few fringe-case routes). The obvious downside is the cost of the actual components themselves, but that should be made up fairly quickly with a few Kamacite farming runs. Definitely a good option for a top-tier hauling boat, though.

I got an Otter last eve on my subs third trip out to DS7. I'm using a straight CCCC build as I wasn't up for the expense of the one Sy part that would have allowed me two hits on the zone (I do get 2 hits on the slab back on Neolith) so RNG was kind to me. I repaired the sub before every trip back out on all parts, and sent it to DS7 as a first stop.

I want to extend a hand of appreciation for everyone in this thread that has supplied research and info on the topic. It let me figure out what I should, and could manage to build while i chased the otter, and now I can build up my FC's bank a bit.

A tale of two subs.

I checked in two subs, both CUUC build, both dispatched at exactly the same time (give or take a couple of minutes) to DSS7.

Sub 1 was at repair level 67/66/66/67 when launched, got a C rating, brought in 14 ice clusters (volcanic weather) and then an Abroader Otter (clear and calm on second anomaly), and the trip was rated "abysmal."

Sub 2 was at the same repair level, got an S rating, had clear weather for both stops, brought in one frosted glass and one Belah'dian glass, and the trip was rated "satisfactory."

The RNG is strong with this one.

Did some data analysis on my subs' visits to DSS7 and I've included the summary I made in Excel. It turns out that the loot you get is ABSOLUTELY determined first by the weather your submersible encounters. As in, you will only ever get certain drops in certain weather: otters in clear and calm (which we already knew) but also deep-red clusters only in volcanic weather and materia only in strong currents, and so on for the rest of the loot table. So it looks like the flow of results determination in the code is something like:

(1) Determine weather for first anomaly with a random roll, 50% volcanic, 25% currents, 25% clear & calm
(2) Roll result on first anomaly from weather loot table (range of results constrained by sub stats)
(3) Determine if second anomaly can be found (based on Favor stat)
(4) Determine if second anomaly can be harvested (based on ???? -- if the result is "no", message returned is "CSCFIFFE")
(5) Determine weather for second anomaly using same base percentage chance as on first anomaly
(6) Roll result on second anomaly from weather loot table (range of results constrained by sub stats)

Right now it looks like getting an otter, assuming your sub base stats allow that, requires two random rolls, one for weather (25% chance) and one on the actual loot table (can't tell for sure but probably around 5-7% chance max.) In other words, assuming all your stats allow you to get an otter, your odds to find one on any successful try are around 25% times 7%, or around 2% chance overall. So, NOT GOOD! You need lots of rolls to overcome these odds regularly so for best otter farming we should focus on making sure our subs get as many rolls as possible in the shortest amount of time. That would seem to mean fitting for high surveillance (to enable the loot table to have otters on it), high favor (for two tries per visit to DSS7), high speed (to get to DSS7 and back as quick as possible) and don't worry about retrieval or range (as long as you can reach DSS7).

One thing I'm still looking at is if the misses on the second anomaly ("CSCFIFFE") are entirely random or if there's some pattern based on sub stats or repair level or whatever. I don't see any patterns yet but I am still updating my Google sheet as more info comes in, so if you're bored and good with analysis, please take a look and report if you find anything!

Interesting... I will need to test this on one of my Alts.

I would not be surprised if the true drop percentiles come out to be closer to 5% increments (5,10,15,20,25,etc). SE has a habit of rounding their numbers in that regard. Furthermore, given the data presented and with the knowledge of the minimum stats required (140/0/0/39/105), it would be obvious then that the CUUC is the current king of farming Abroader Otters exclusively.

It's a good thing that the CCSyC and the CUUC as so interchangeable, then. Just about everybody has Unkiu parts laying around.

Also a further point that the Rating system is meaningless, lmao.

[AuricSeagard]

Out of curiosity I ran the same loot and weather analysis for my test runs on the Sunken Vault and the Wreck of Discovery I and I found the same absolute correlation between weather type and loot table.
