• if you start from "Shackles Den", goes eastwards, over the whole rocks in the sea, the area of "Mak'rana". Go to the higher island, where you can see a path. In the sea, between two large skeletal marine creatures and next to a shark carcass, you can see a small geyser, which is the Tide Behemoth. Attack and fight it. The Tide Behemoth is then divided into two. In the final phase you have to fight three of them.
