Note that a Paracer can NOT damage stone. Build a fair sized trap and lure it in. I used my base walls since they are very large, but a normal Dino gate room should do the trick. After that, fire away from safety.
Here is a hard but easy way to tame a paracer. Go to a high point on the ledge of the tall rock in the Swamp next to redwoods. Get lots of tranqs. It might be hard, but keep on trying. Soon the Paracer will torpor run. You can shoot it in the swamp water, just make sure its not too high. Put loads of narcotics and berries in there. Have fun with your new mount. It's saddle is cheap, so you don't have to worry. I hope this helps!
If your on mobile here’s a great tip on taming one of these dudes 1 build a trap using four gates any kind place three in a u. Shape and then punch or aggro one of them lead them into the trap place the last one behind 2 if other ones are coming after you then just quickly go out of the game and then back in it will make them non aggro and then tranc the one you have in trap when it’s down shove berrys down it’s throat or it’s fav kibble BOOOM! You have one please up this if it helped thx
