My tips are to use a bola if you have one to keep it in one place then knock out using stones on at tanqs. If you don't have a bola try finding one in an open area and pelt it with stones. To avoid its attacks run around in circles and reverse your movement when it is catching up or when it charges just walk out of its way and you can pelt it with stones while it charges as it is rather slow.
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!!
