The only dino that'll agro an unconscious paracer is a Rex. So if those are taken care off and your cautious about not bringing in extra friend with you. You don't have to worry about other creature damaging your tame.
So this guy's are quite easy to tame you just need to build a 4x4stone foundation then stone dino gateways but don't put the last2 gates you need it to trap the paracer you also need large bear trap then after done putting all the traps find a paracer the color and level you like shot it one time of tranq arrows then wait for it to chase you then go near the trap after it traps to the large beer trap put the last2 dino gateway so it can't escape then enjoy taming your paracer btw they are good for travelling cause you can build a house on them sorry for some of my English
I don’t know if anyone else has experienced this but I tried taking one of these on my own with no trap, the parapet continuously fake ran away and then returned. I loaded over 90 tranqs in to it and it never got close to going down even on a boosted server. So use a trap, I died many times to bring you this information.
