Climb a rock, make sure it can’t climb too, then shoot it with tranqs. I managed to knock it out with 3 trans arrows. Mejoberries are better than the other berries. Takes awhile to tame.
Hope this helped. :)
Very easy to tranq, they’re slow. Make sure to tranq one that’s alone or move the others away because things can get difficult with multiple. Very useful for metal, and their eggs can be used for regular kibble.
