Wondering how easy it is to tame one of these guys? I’ll tell you!
not simple nor hard.
simply have a water mount to swim out to an area where you have spotted plesiosaur(s) or know where they spawn at, once you have your plesio in sight, be wary of the threats nearby.
It is important to kill off any nearby predators that could intervene into the taming process. (Ex: megalodon)
Next, be at a certain surface level (how deep you are in) to the point where the plesiosaur won’t try to swim to you from, and knock it out with whatever tranquilizer method you have (I used a crossbow and ichthyosaurus) and begin the taming process.
Also remember to bring at least 100 narcotics for whatever level.
My trusty sarcosuchus made knocking my plesi exceedingly simple, for three reasons. The sarco is fast, it ascends quickly, and you can shoot from its back. Once I separated my plesiosaur from her friend and killed it, the procedure was simple. When the plesi reaches a certain height it begins to flee. I dragged her up then filled her with tranqs until she aggro'd again. Repeat process until unconscious. Simple with sarco.
There is a glitch at the redwood on the center, where plesiosaurs will spawn really near the coast and whole groups of 2 or 3 are glitched in the water, meaning you can knock out multiple plesiosaurs at the time.
The trick is to argo one, have him chase you into an underwater cave where he will not be able to fit through the door but his long neck and head does. when you do this he will not de-agro, you can then get a clear shot from the cave with a bow and tranq arrows
Taming one is not too difficult. A high level won’t take too many tranq to knock out. When it’s knocked out, feeding it a soothing balm will allow u to tame it quickly, even with regular raw meat. Don’t forget to separate the plesiosaur u want from others in the area. Good luck!
