Even for a person like me who doesn’t fear reapers anymore ghost leviathans still scare the living daylights out of me. It’s especially creepy when they can disappear once you have made enough distance. So to make things short, I wouldn’t be too cocky about exploring the blood kelp zone (unless you’re exploring the zone where you enter through a trench. As far as I’m certain no ghost leviathans spawn there).
Ghost leviathans are cute sometimes, ngl. I'm making some cute art of them soon. I like making fan art. I also have a pice of a seamoth looking down on an underwater Portland, Or.
