About Ebisu's Hidden Fishing Skill +46 Proposal
Summary (TL;DR)
Hey there fishers! So I was originally going to post this in the general fishing thread, but I ended up gathering a bit more data than I had intended to and decided that I should make a new thread so the information is more readily accessible to all without it getting buried/lost several pages later.
I had initially set off to confirm/verify for myself if the Fishermen's stall was indeed +5 fishing skill like the other stalls, since wiki has it listed as +3 for some odd reason (also due to the fact that I could never find any solid testing data on it, and since Advanced Fishing Support is said to give +2 skill while crafting gives +3, I wanted to verify that this wasn't the case with the stalls either). While testing, I also checked a few other things with the new Ebisu +1/Lu Shang's +1 I had recently acquired, and gathered some interesting data. Here are my findings:
Base Fishing Skill: 110
Target Fish: armored pisces (Skill Cap: 108) [Source on the 108 skill cap: Armored Pisces Wiki Talk Page, confirmed by Hammy025]
Required Skill for Auto-Depletion (13+ skill above fish cap): 121 [Auto-Depletion Source: cdgreg's Fishing Data Compilation on Blue Gartr Forums]
None of the "Angler's Sense" messages were used for data.
The first test had auto-depletion at 116 + Mega Moglification while the second test with 115 + Mega Moglification did not, so we know the first test hit the 121 skill threshold for auto-depletion. With that, we can deduce that 121 - 116 = 5, meaning the stall does indeed give +5 fishing skill.
I was able to conclude that the Lu Shang's Fishing Rod +1 does not receive any additional auto-depletion benefits from its NQ counterpart. With this, I decided to put away the Willow Fishing Rod for the remainder of the tests.
Similar to before, the first test with 119 skill + Advanced Fishing Support hit the auto-depletion threshold, whereas the 118 skill + Advanced Fishing Support did not. Thus, we can conclude that 121 - 119 = 2, meaning the Advanced Fishing Support grants +2 fishing skill.
That either the combined skill difference of +13 (over the fish's skill cap) and +46 (the proposed hidden Ebisu skill) was breaking two different tiers of auto-depletion.
Or that Ebisu just natively has its own auto-depletion which is equal to a fish's auto-regen (which would also explain cdgreg's stagnant result, as the two cancelled each other out), and that breaking the 13 skill difference above the fish's cap further added to the auto-depletion.
To test for this, I decided to record and time how long it would take the auto-depletion to drain the target's HP down to 0 in order to determine its potency, at both 120 and 121 skill levels, using both the Ebisu and the Lu Shang's.
I used this Stopwatch for my benchmarking
For Ebisu with 120 skill (not reaching the natural auto-depletion tier), the auto-depletion dropped the fish to about 10% HP in 50 seconds before I timed out. At 121 skill, the fish reached 0% HP in about 19 seconds.
For Lu Shang's, there was obviously no depletion at 120 skill. At 121 skill, the fish was fully drained to 0% after about 29 seconds.
From the above tests, we can see that Ebisu's auto-depletion at 120 skill did not come close to touching Lu Shang's auto-depletion at 121 skill, showing that they differ in potency. If Ebisu had hidden +46 skill, which would've easily broken the +13 skill tier above the fish's skill cap for auto-depletion, the potency should've at least been the same, if not more potent.
From this, we should be able to conclude that Ebisu does not gain extra hidden fishing skill+46, but instead has its own native auto-depletion property which is roughly equal in potency to a fish's auto-regen when your fishing skill is 25 or below its skill cap (which can also explain the stagnant effect when both conflict and cancel out).
Fishermen's stall grants +5 fishing skill.
Advanced Fishing Support grants +2 fishing skill.
Lu Shang's fishing rod +1 does not gain hidden auto-depletion like Ebisu.
ebisu fishing rod/ebisu fishing Rod +1 does not have hidden fishing skill +46, but instead a native auto-depletion effect that is roughly equal to a fish's auto-regen (when -25 skill or below the fish's skill cap), which stacks with the existing auto-depletion when fishing skill is +13 or higher than the fish's skill cap.
I hope this data proves to be useful or at least an interesting read for you avid fishers out there — Happy Fishing!
