Just get a few spears, then stab them in the head while slowly walking backwards. If your brave enough, us a club to knock them out. But if you don’t want two-thirds of your health gone, use tranq arrows.
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.
