Baryonixes are great for caves.I recently farmed artifact of the hunter's cave with a lvl 40 on easy mode. It has about 1500 health and was able to kill arthroes and tens of areaneos at once.I got about 30 stacks of meat,1100 chitin and 150 hide and also lots of metal picks hatchets and arrows(normal and tranq) and the artifact itself(which I tributed and got a soothing balm) from the cave.It also leveled up two times.

If you want tranq arrows don't waste your narcotics and kill areaneos in caves with this ultimate cave mount
