I have discovered the way to easy tame these things!! What you need to do is trap the pegomastax in a closed area and have two tribe members with a bunch of mejo berrys ( make sure you always have a stack of 100 in the last slot of your hot bar) make sure both of the tribe members are standing next to each other and when the pego attacks ( robs ) you it will hit both of you at once making the taming a lot quicker and easier !! You're welcome !
literally bought console ark after playing mobile ark for ages, this little sh it came and robbed me of my tranq arrows, then, had the audacity to come and tame itself on me after taking my 20 mejoberries, didn’t want this pet but I took it home, died 20 seconds later to a bird that picked it up and ate it, still don’t know why or how but I also don’t care
