Aetherfin guide
Roslit Bay is the only place that lists the Aetherfin, and it is the sort of entry where the data stays quiet: no bait, hour, weather or season is given. What is documented is the rarity, Divine Secret, and the numbers that come with it.
Weight is wildly uneven. The range runs from 1 kg up to 21,000 kg, with an average of 5,000.5 kg, and the max ranks 76th of 663. At C$6 per kg the average sale comes to C$30,003, 56th of 742 by average value. Base XP is 20,000. That puts it among the few catches whose payout reaches five figures with ease.
You can gear up in the zone. Roslit Bay sells Blazebringer Rod, Magma Rod, Fortune Rod, Rapid Rod and Steady Rod, which gives you plenty of choice before you start. The wiki calls it a surreal form of manta ray, an extremely rare and unknown catch.
Verdict: since the conditions are unknown, plan on luck rather than a schedule. Bring your best rod from the five on offer and fish Roslit Bay patiently. A C$30,003 average makes it a very good day when it does bite.
