Easily knocked out when you use a bloa. When stuck shoot in head while you can and itll go down quickly. Tranq darts make the process quicker, but arrows will do the job just fine. They can be picked up and dropped into safe taming cages by argies to make this easy tame all the more easy.
So if you start at west zone 3 and head north a ways there is this nice beach surrounded by a rocky jungle, you should probably build a base there, then if you have some bolas and some tranq stuff head north a tiny bit until you reach a big rock (I’ve nicknamed it “jungle rock”) and the tigers are usually their. Use your little brother as bait (or whatever works best for you) then bola and tranq! I found this useful and it is a great way to be really tough at a low level.
Make a taming pen->Take your argentavis->head on to the dead Island(carno island)->find a good level with spy glass->grab that sabertooth with your argentavis->bring saber back to your taming pen and drop'em!.->tranq 'em->
(If argentavis is on low of health,drop sabertooth on a safe place and kill some parasaur to regain health and stam)
Tip for developer if any..
Sabertooth needs a critical attack (35-45%+damage)after killing,for a period of time..[atleast they are saber toothed]
