Just go to eldrich zone on crystal isles and look for big bubbles that have some black clams/oysters inside of them, put your angler fish inside the bubble, harvest, and enjoy the best black pearls harvester in the entire game, super easy, rank up for people to see this.

Gachas get about 60 per good crystal if you’re lucky or they get 25-30

first tame an ichthy then go to rag about 75,23 more black pearls then you can carry on the sea floor and not to dangerous just keep an eye out for megs

When you want black pearls in great quantity, here are some things I suggest.
1: Ragnarok: Vikings bay. Bring a good crossbow to one shot any water scorpions, they drop TONS of black pearls.
2:Extiction: Gachas. Sometimes when taming gachas, you can get one that produces black pearls. They produce in big quantities, and for me is by far the safest and easiest way to get the black pearls. Like if this helps!😄

The one best way on island is to get black pearls by killing alpha mosa they spawn common behind carno or dead island or by erypterid sea scorpions they droop too

When low level tame otter and make it kill fish there is a chance it will get a black pearl

How I get in ark mobile?? , Can I have some other tips for it because I'm tired of otter

Kill tusos sea scorpions nautilus and alpha mosa and tuso

If u play at Ragnarok just get to the ship in vicking bay and farm a lot of black pearls

If You Have Tuso You Can Easly Kill Alpha Mosa Or Tuso
