Super East to tame, I just cornered it and clubbed it till it was unconscious. Then I feed it, that was the hardest part. I had to harvest berries while taming, so be preped if you want to tame one of these suckers, or just knockout near lots of bushes.
Since I use these things for fertilizer I didn't know what to upgrade so I just went with speed. Now this phioma has 300% movement speed and is faster than raptors. It's so fun to see a pig run this fast.
