Aggressive fast and run in packs! Definitely take out the ones you don’t want first, otherwise they will eat the your prize. Prime works fast but can be done with patients using the good ole chuck roast raw meat. I took the Alfa , down with 6-7 tranqs. To the back of her head while she ate her pack. Loyalty is not there strong suit. Careful they do those stupid circles when following you home(cliffs, trees rocks or other Dino’s ) which complicates your journey . Don’t let your Dino dangle. 😀
Allosaurus are found in packs and often mate-boosted. Any mate-boosted creature only takes 70% of the normal damage and therefore requires around 43% more damage and torpor to either kill or knock down. The alpha, which for the reason of being the highest leveled is the most sought after, has another bonus on top of this that when together with the mate boost makes them around 2 times as resistant to damage and the torpor it may come with.
Now stop crying about how it takes more resources to take one down and use your time to devise a plan to separate the Allo you want from the rest.
TIP: You are unlikely to outrun one on foot or with most carnivore mounts, so be sure to bring something fast or beefy.
Allos' are like land sharks. They can see you from a mile away, travel in packs, and are extremely fast. Chances are if you can see it, it's too late for you if you're on foot.
Best chance for survival is find another Dino and run beside it to try and get agro off yourself
In my opinion, the safest and most effective way to tame is to make a dino pen and pick one up with your wyvern and drop it in the dino pen.
These guys are always in highland areas and travel in packs.
Also if you get bit by the alpha you will bleed out!
