Grab a slingshot and keep on hitting it on the face then when it’s down grab berries, kibble, or crops. After that maybe but narco berries or narcotics so it can stay asleep. Wait till it’s done then you have yourself one. Sorry for bad grammar.
If you are going to tame one of these be on ahigh place gat loys of rocks and slingshot it, they’ll kill you if your where they can reach you. These things can pack a punch and tank alot of DMG be careful when taming them! And you need berries to tame them
When taming or attempting to knockout the sling shot is your best option. You can easily get a knockout without taking damage by shooting while backing away since the carbonemys will begin following you after the first shot.
