Can I just say you shouldn't be scared of these things because their scary. They're humans. Humans that touched the liquid element. So the next time you say let's swim it the cool purple stuff and die just think what you turned into.
When about three spawn, one will turn into a alpha, ( large and orange) which are the ones that drop the venom. WARNING: When they drop the venom, a bag will drop with the venom inside, it won’t go into your or your tames inventory!!! If ten spawn, a reaper will appear. Keep a light pet with you so they don’t overwhelm you. Light pets will burn them, doing major damage. That’s really all you need to know to fight them!
Easy Venom Trap: Two billboards in a v-shape, trap the alpha (orange one) and stand in front of the trap they will constantly spawn.. If you only want venom disable resource harvesting on your dino because after you get to half weight on your tame the venom will drop in a bag
