Don’t waste darts on these things tranq arrows are cheaper and basically have the same effect. Slingshots are also advised as they are even cheaper and work just as well. Crops also isn’t much better than mejoberries.
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.
