Kill elites gators elite anaconda I think lions might give the premium thick hide to make the premium thick leather. You will need premium leather to make the iron weapons
elite gators are the best, there is one near my main base on stream, and 3 more the on islands between the hill area and the rainforest. if you have a jag mount easy to run to and farm and get enough for itleast a full set of armor on that run of 4 gators
