Tamed my pachy on craggs island, called it slappy. They are quite slow but the charge adds some speed in short bursts, I charge until out of stam and them set him to follow while he gets stam back and charge again, knocked out a couple of dodos while charging.
Pachy' don't deal large amounts of damage but their attacks will deal torpor. When fighting in the wild don't engage packs large then 3 if you only have basic weapons because they will knock you out quickly then have their way with you.
FOR NEW PLAYERS!!!UP FOR PLAYERS TO SEE!!! Do not attack unless you have an Ebola (sorry about the spelling) and knock it out with your fist or club. I used berries and soothing balm. Good luck survivors!!
