Calming sea waves crash into the rocks in the seashore as monsters slowly emerge one by one from the waters. It was like an invasion of pretty much all bosses that are living in the water. From time to time, there are also the flying bosses emerging from the water but most of the time, they are all monsters that walk on land and can either survive the land.
The monsters are repeatedly appearing but there is quite a lot of variety so it wasn't the same monster over and over again. As time goes by, the monsters get tougher and tougher to the point where killing the first monster boss I killed after descending here, the Corrupted Crab took a bit longer to kill completely.
It's been 3 hours since I started killing my way on the monsters. I utilized different approach here and there to efficiently kill the monsters. Since it's not that hard at first, I continue to just kill and kill with my weapons. And like I said, this boss rush gets harder as it progress a lot longer.
