These things are a total pain to tame, and i highly suggest you find tutorials before taming, because i guarantee death for anyone who doesnt know what their doing.

They do not roar if their on bad landscape, make sure to lure them to a flat area.

Traps are optional, but highly recommended.

Low quality weaponry is not advised. Always have a high quality shotgun (preferably) or a fabricated sniper.

Damage from creatures will not work.

You can use a extremely tanky creature to tank hits so you can avoid harm (creatures like a deinosuchus) while you shoot it.

It has 2 roars. A healing roar, and the roar when your ment to feed it. The healing roar starts with it “inspecting” you and its head is lowered. It will then aggressively throw its head up to roar. Do not approach at this time. The second has it immediately roar. Feed and run.

I hope this helps someone tame a acro, good luck searching and happy taming.
