Submersible Information Thread

[Myriads]

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.

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.

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.

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.

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.

Salvaged coin is also clear and calm. http://prntscr.com/mzda6h

Been trying to send my CSCC submersible to Deep-sea Site 7 for the otter minion. The last 5 times the ratings are C, and the log complains about "volcanic activity". Is the rating entirely RNG?

As for the build, I'm unsure as to what points to the minimum favor stat. Might need to build extra parts.

The ratings are meaningless. They're based on the amount of items you collect, but don't take into account the value of the actual item. It is and isn't RNG, but you can basically ignore it.

Volcanic Activity is a weather effect that shows up 50% of the time and drops items of lesser value. Clear and Calm has a 25% chance of occurring but, even then, the Abroader Otter is incredibly rare.

I can't quite tell whether you meant that you're using a Shark part or a Syldra part, but the Shark version of CSCC doesn't have decent enough stats to farm for the Abroader Otter. At 130 Surveillance, it's 10 points short from meeting the minimum requirements. 90 Favor is 15 points short on spawning second anomalies, so you'll only get one attempt per voyage.

If you want a simpler boat to attempt to farm it, try the CUUC fit to farm Deep-Sea Site 7 (W). On the other hand, you can also build a CCSyC if you want to travel to more destinations than that.

It's a Syldra part. The submersible has like 190 surveillance if I recall right, but it's missing some favor and our FC made a 4th submersible, but in the process we used our spare bow, so now I have no way to swap bows between subs. I think we'll make an Unkiu bow as you suggested.
