If you want to tame a Phiomia you need 1 bola 1 club and you have to hit it in the head to knock it out because if you hit it in the body it will break free of the bola before you knock it out.Phiomia are great early game tames and late game you should use it mostly for fertilizer by feeding it stimberries.If you use it to ride on you need to upgrade its stamina movement speed and damage.
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.
