The dossier flat out lies, these things will agro from a fairly long range and pursue you quite insistently they also spawn in the shallows A LOT so if you planned to build a comfy open dock from which you could appreciate the sunset, well tough luck get used to your drab behemoth gates.
Use a basilosaurus to fight them. Since all their attacks involve electricity unlike the electric eels which can bite, they are doing no damage to the basilosaurus. Just spam the attack button and don’t forget to harvest their body for toxin too!
Up to 15 tentacles grow from each corner of the bell and can reach 10 feet in length. Each tentacle has about 5,000 stinging cells, which are triggered not by touch but by the presence of a chemical on the outer layer of its prey.
These creatures are the hardest creature to kill if u don’t know how to. I hate when I go fishing and they come at me, so I tried to kill one with a special tactic I thought of. First you go into the water and draw the jelly’s closer to the shore. Next you try to get them to follow u on the sand (don’t hit them just go in and out of the water, they will die if there out of the ocean). If that doesn't work get a good sword or something and kill them with that vary carefully. If u do get stung in or out the water hit them with anything but your fist to kill them then run.
