You will need a turtle that has more health than agiga, no joke, you need 150 kibble tame turtle with all levels into health and reason for high level because it constantly gives your turtle a higher torpor which will then knock it out and then let go of your turtle, when you have that you go to its mouth and feed it black pearls, you may need more than 1 turtle
I tamed one of these and immediately died, of course my reaction was like with most other tames of oh god dammit now it’s gonna die, I zipped over on a dolphin and found it sitting innocently in a ball of about 50 meg carcasses with 2 plesiosaurs in the mix
1: The best place to encounter tuso is 90-91 lat and cover all longitude from red ob to the end of herb Island.
2: Don't solo search, make a party and cover full bottom of the map.
3: Don't search in shallow water and surface, go for mid and deep sea.
4: They need to grab your tame then only can they be tamed.(Take Carbonemys with health and speed pumped)
5: They take 50 black pearls per serving.
6: They only agro in deep sea.
7: Last and the most important, the server must be brutal or their chance of spawning is not that much. Put server to brutal and for one day atleast go killingspree in ocean to open spawn spots for tuso.
You need two people, one for feeding the black pearls and the other to feed the turtle that is in the grasp of the Tusoteuthis, with sweet vegetable cake for the health and to feed it stimulates berries as well
