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.
This thing will run away if you hit it with one punch, if you wanna kill it be sure to do that with big carnivores or just trap it
Btw do you agree this thing looks like a crossbreed of a boar and an elephant?
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.
