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.
The first time I heard one of these little critters, I thought, hey is that a goat?! Anyways, they are fun to have around and tamed, as they knock things out and run pretty fast while charging. However, they have considerably low health and stamina, so they can be quite troublesome when low lvl. But who cares, they make goat noises. If only they could eat anything
