if u are going for an allosaures tame the easiest thing you can do is lead one into a taming pen and then kill the others outside that way they do not have the alpha pack boost affect and you can easily and safely knock it out
The best way to tame an allo is to find the level that you would like and kill off the rest of it's group but if u want all three just get to some high ground and then just start shooting them with tranqs
A simple way to knock it out is to build a 3Ã—3 room with a gate lure them in with a pachyrhinosarus inside then calm them with the pink stuff and just tranq them make sure to keep them passive to have an easy knock out ;)
If you encounter a pack and only want to tame one of them, you can aggro them onto other nearby wild dinosaurs, and eventually break up the pack. This makes it easier to kill off unwanted Allosaurus and eventually single out the prospected tame.
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
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.
When your trying to knock it out make a trap 3 by 3 stone foundations and use stone door frames and build 2 high then run a ram Down on the outside of the pen and lure a allo up it so it falls in for an easy tame DONT USE WOOD WALLS wooden ramps work tho
