This thing is an absolute beast. I tamed a level 120 and pumped nothing but stamina so it could yell at my dinos to do better when fighting the broodmother. They were so inspired, that they got a 25% damage bonus, and a 25% damage resistance bonus meaning we completely shredded the broodmother when it may have been a close fight. One or two of these behind your army and you, my friend, have comrade stalin himself telling your troops to fight to their last breath
The fear roar is amazing for taming because the damage increase reduces the amount of tranqs you would need to use to knockout something. make sure to have already caged the creature though because if you don't they will run away.
Once tamed, upgrade stamina if you chose a low level individual. Their roar takes a lot of stamina, so higher levels are recommended. If you can get a lot, you can position them surrounding your base, and they will roar at any attackers that come too close, weakening them and even scaring them off.
Yes yes ou can ally wild carnos to help you, but what would be better is if it could bend enemy tribe's carnos to do your bidding! Roar next to a tribe with mostly carnos and watch them break them from the inside, how evil would that be?!
I built some fences for keep my dinos safe. but maybe there are some holes I didn’t recognize so some small dinos can come in and attacked my baby dinos. so I tamed a low level yuti for a guard(turret mode) problem solved.
