Actually easier than youd think to find it go to the very corner of the island map doesn't matter which one but dive deep, use a tame with high health and let it grab it swim up to its mouth and feed black Pearl's (last hotbar slot) at the moment its x4 so its quick a lvl 75 takes one feed of 75 Pearl's 1000% worth the time to tame but gets some getting used to. Once tamed lvl up the health melee and stam for a beast that will dominate all it faces
