In my opinion this is easily the best shoulder mount. It brings you fish that contain raw prime meat and sending it to attack a Dodo can get you raw prime meat. I have x1.5 harvest rate and got somewhere around 12 raw prime meat from one Dodo. An absolute must have
When set to "Hunt & Retrieve" it will bring you dodos or fish and the dodos will give raw prime or a few of it. And fish will give raw prime fish meat. You'll know cause the corpse will glow yellow as the icthyornis is bringing it to you!
