they have health that can rival Rexs and loads of damage, but that doesn’t mean they are invincible.
I lost a decent one to an Elemental, it was a stupid and arrogant move to fight back, don’t make the same mistake.
I use my paracer as my cargo transport dino for short to mid distance. I use it to go to the redwood nearby and gather MASSIVE amounts of metal. Just hop off, get the metal, load up the paracer, then get back home. They can defend themselves quite effectively
On Scorched Earth the Paracer with its platform saddle is a needed tame. You can put a cannon on it and use it for taming Rock Elementals or use its high weight and health for carrying large loads of supplies around through dangerous areas.
