Just don't let up. After each feeding of narcotic or biotoxin. You can continue pumping damage into it. If the does the fake raor. Continue to shoot it while it does this. By the end of the fake roar it should do a real one. If you miss a feeding it will go into adrenaline stat. At which point it will NOT go to shield stance and you must wait for it to stop glowing red. I don't usually clear out wildlife as i use them to heal the Acro if I do mess up. Good luck and hope you get the best Acro's!

Having tamed quite a few of these on center and on the new gen one map I've learned a few things. First come prepared, make sure you have enough biotoxin or narcotics and ammo. Second you don't have to use a pump shotgun, double barrel feels much better because it's higher damage and doesn't waste as many shots. And last taming on foot is a lot easier than you think, just kite it shoot it and feed. Good luck

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.

Be careful because if one is to low of a level you might accidentally kill it when trying to tame it

I have seen it on island! Down from 50/50 there was like 6 there around that little pond oasis.

Biotoxin in your last slot. Goot shooter with good damage and ammo.

Find acro you want to tame. Clear the area of other wilds when its not aggroed shoot it untill it goes into stance/guard this means it walking towards you sideways slowly, a few more shots will make it roar. There are THREE roars only one you can feed on and its the roar where the acro throw it head up and back down qucikly and roars mouth wide open. Run and spawn interact, on playstaion its triangle PC 'E" if successful the acro will shake its head like it had a bad taste in its mouth. I run towards its tail ehich makes the acri turn to find ou giving you time to get some distance. Acro will still be in guard stance shoot it again untill you get a feed roar. Repeat untill it knocks out. BEWARE if you miss a feed it will rage and wont heal and trying ti shoot it back into guard will onky kill it. You need to lure it to a dead dino to eat and onky then can you continue the taming process. The low rumble roar with head low the acro will exit guard stance but you can shoot it back into guard stance after this roar.

Always spam interact when feeding narco/biotoxin as sometimes you can pick up stone or berries instead and miss a feed. Do not miss a feed. If you do give it time to kill somethine or you will kill it.

If you go to carnivore Island they spawn there a lot, if you go around and kill the medium and small dinos then they will spawn more

An easy way to tame him once you are into late-game and have a Tek chestplate.

-a good amount of Bio toxin.

-try avoiding Pump shotguns and rather go for a fabricated sniper rifle. (The rifle does damage in per bullet which makes it easier to control the situation)

-a tek chestplate.

So basically you just hover over him and tick away his health until he goes into a defensive stance. Tick away some more and he SOMETIMES does his adrenaline roar. Not to be mistaken with his health restoration roar. Once he does his roar you need to dive bomb him by disabling your chestplate and spamming the feeding button. And basically rinse and repeat!

And if somehow you screw up and do his health too low you can lead him to weak creatures, he will eat them and restore about 50% of his health which grants you a second chance!

For me the most important thing taming these guys has been to have a large, open space. They seem to not enter the taming roar if they have to navigate around anything. Pick an open spot, but also clear trees and other blockers.

The rhyniognatha can pick it up for the pvp people.

pretty sure they can damage stone and metal structures while in shield stance

1000+ dura flak and capped shotty just run circles around it even with a wild 150, doesn’t inflict crazy damage.. Easy as

Awesome tame ,a little slow but it makes up for it with coolness!

THEY CAN DESTROY THESE STRUCTURES:

Thatch

Wood

Stone

Metal

Tek

Yes I could’ve said THEY DESROY ALL STRUCTURES but that’s boring 🥱

Uhhhh anyways I was right about them being a powerhouse because they can go into boss fights…

And they do SO much damage.

This is how I did mine. Works relatively well and simple. If you have an ice wyvern with low dmg and pumped stamina this can work:

1- make sure the surrounding area is isolated around the acro you wish to tame.

2- Stop a short distance from the acro within ice breath’s distance.

3- ice breath the acro repeatedly

4- acro will switch to defensive, then do the loud roar if it takes enough dmg (watchout for the low roar, it’s a bait roar)

5- while it does the load roar, run up the top of your ice wyvern’s neck to force-feed the acro narcotics (I used bio toxin)

6- repeat until it knocks out

Continue to watch your back so you don’t end up backing up against anything or any other animals that could possibly interfere with the process.

P.S.- as of it’s new release, trapping the acro does not work at the moment. It’s taming mechanic will not trigger if trapped.

Hope this helps!

I found one on extinction but no gigas and 1 carcha, I’m on day 86

Pro tip, don't use a stereotypical metal box to trap an Acro. If you really need to restrict it's movement, you can use a wall of metal billboards, so long as it can still move around. The easiest way I learned is to just back up as it walks to you, and if it does the fake out roar then run away from it

Ice wyvern method did NOT work, rip lvl 145 acro

A level 145 takes 55 Biotoxin on 2x to knock if you feed every chance

Yes you can find them on the Island. I found one while trudging through the swamps of all places.
