To tame a carcha like a pro:

1. you will need

•an Argy(or a cryopod if you do not have one)

• a child Paracer or Rex

2.find the Carcha, dont get too close, but close enough to walk to it safely without being attacked by other dinos

3. get the child Rex or Paracer and kill it

4.drag the body of the rex/paracer to the Carcha. When the Carcha starts sniffing in the air, drop the body and back up a little bit

5. the Carcha will have 100% trust and you will walk up to it and ride it

6. kill every creature in the area, and the taming progress will increase(note: taking damage will decrease taming effectiveness)

7. after a couple kills you may want to use the roar(right stick or R3 for controller, not sure about pc) this is because u might get kicked off of the tame as you kill more creatures. Im not sure if it was a bug or not but it has happened to me.

8. enjoy your Carcha :)
