Not efficient, but relable way to get biotoxin: run near them in water them swim to a coastline and wait. They will pursue. Then back up just enough in the water where they cant go forward, but you can hit them with a pike or spear. This even works with stuff like axes. I did this on my third day I ever played this game. Had no use for biotoxin though.
More Cnidaria Utility Tips
Basically no utility except biotoxin, only go after them with weapons that have long ranges and MAKE SURE YOUR TAMES WON’T CHASE THEM!!! When I was a noob I watched my entire dilo pack run after them and watched as they were all slowly and brutally murdered, and I’ll probably lose more tames to those monsters later. If a troll was a creature, it would probably be this one. One ☝️ = one RIP for every tame lost to these.
These guys are annoying when i step in the water they attack and kill me. I know this jellyfish species its the deadly box jellyfish that that kills you in the ocean. Me and my carbonemys are swimming in the water to find dossiers and box jellyfish attack me and dies. 1 like= remove box jellyfish
