Make sure you know when it’s knocked out while taming because they look the same when their knocked out as if they are still alive. I made the mistake of killing the taming effectiveness as a result of tranqing it after it was already knocked! 🤦♂️
Kill something (Moschops and Phiomia are good because they provide a lot of meat) before shooting it, then lead the Dimetrodon to the corpse as you tranq it. Around halfway through the process or when its low on health stand near the corpse and let the Dimetrodon attack you. It will consume the corpse as it attacks you, and regain health. This way there will be no risk of killing it. You can also use a Snow Owl to heal it if you have one.
It Says You Can Carry By Using An Argy, But You Can’t Which Is Really Stupid If You Think Of It. An Argy Is Able To Carry A Parasaur But Not This Dumb Dino... They Should Really Fix It Cause I Tamed It Near The Red Woods, In The Swamp While My Base Is At The Western Plains. So I Has To Fcking Walk All The Way With This Slow Creature Behind Me. Rip.
