Allos CAN be carried by a Quetz. Did it on official yesterday.

If you see a tip that talks about the pack boost giving "a 50% damage increase and a 25% damage reduction, so if you have an imprinted pack leader, it gains a total of 55% damage reduction which is an extreme damage reduction", then that guy is exaggerating as the pack boost actually gives the alpha a 25% damage increase and a 12.5% damage reduction so if you have a 100% imprinted pack leader it will actually give it a 38.75% damage reduction which is not an extreme damage reduction as it is multiplicitive not additive.

Math: 70% damage taken (100% imprint buff) × 87.5% damage taken (pack mate buff) = 61.25% damage taken = 38.75 % damage reduction

Also for the pack mate boost to be effective you have to have friends that can ride the other 1 or more allos, or whistle follow your allos to the pack leader since they don't passively do it by themselves, which makes them unable to attack other creatures that are attacking them.

Allos are my one of my favourite if not my most favourite creature in all of Ark and if I’m being honest I believe Allos are underrated, and I’ll tell you why. Some people question their uses because if you want a fast ground mount people tend to choose a Carno and if they want a power mount they choose a Rex or a Spino. Allos are in between, fast and a good damage; alone they are dangerous but in packs they are a force to be reckoned with because we all (or most of us at least) know about the pack ability that these gain when in a pack of at least 3, the bleed effect attack, now this attack drains 5% of the targets damage over 10 seconds which means using that specific attack, it can 20 shot any enemy. Using an Allosauruses bleed against a Giga or a Titan will significantly damage it but it would be best to use the Allos as the main damage while another dino tanks all the damage. Anyways, to further explain the pack bonus, the leader will be the highest level (obviously) and the leader does not only gain new attacks but they receive a 50% damage increase and a 25% damage reduction, so if you have an imprinted pack leader, it gains a total of 55% damage reduction which is an extreme damage reduction. There can also be multiple pack leaders, especially when in multiples of 3. Thanks for reading, I hope you found this helpful and might reconsider your thoughts on the Allos.

If you can manage to tame multiple Allos then it will be easier to hunt other stuff with them not just because you have more but the fact that in groups they get a buff. UP please this is my first tip. Hope you liked!

What I did is I found one and ran up a steep mountain and they couldn’t come up their with me so I knocked the high level ones and killed the low ones

If you have a group of 3 or more tamed then the highest level will become an alpha which will give it a new attack and bleed effect.

Allos stay alone until another allo gets close enough. When an allo finds another allo they will join forces and form a pack. The highest level allo becomes the leader once the pack reaches a size of 3 allos. A pack of allos will always follow each others no matter what. They usually follow the leader, but can follow a different allo if say a player calls over that specific allo to follow him . If they wander too far from each other the bond will be broken and the allos will set off on their own until they find each other again or other allos. Once a pack reaches a certain size the allos will stop accepting other allos in their pack. The same goes for tamed allos. Once they reach the max pack size of 15 and more allos are introduced your original 15 allos and the new allos will form different packs. Hope this helps you understand allosaurus pack behaviors. Thanks for reading.

Think about this: The taming in ark is crazy. The last thing the Dino would remember would be you impaling it in the face with toxic arrows before it gets knocked unconscious. And then somehow it eats while knocked out which makes no sense and then wakes up and loves you till it dies.

Everyone hyping up the pack boost for no reason when allos don't even follow the pack leader allo passively when tamed unless whistled follow to the leader allo, which will make them only follow and refuse to attack, or if you set the pack leader allo to aggressive and the other allos to neutral (good luck having your other neutral tames also follow the pack leader allo)

Allos DON'T stay alone until another allo gets close enough, instead they will always spawn together in packs of 3. When an allo finds another allo they will join forces and form a pack, because it is coded in the game that dinos tend to wander near other dinos of the same species. The highest level allo becomes the leader once the pack reaches a size of NOT 3 BUT AT LEAST 2 allos. A pack of allos will usually follow each "others" no matter what, since it is coded in the game that if any dino gets aggroed then goes to a location, any dinos near that one will follow it. IF WILD They usually follow the leader, if tamed they will NOT passively follow the leader but can follow a different allo if say a plaver calls over that specific allo to follow him If they wander too far from each other the bond will be broken and the allos will set off on their own until they find each other again or other allos. Once a pack reaches a certain size the allos will stop accepting other allos in their pack. The same goes for tamed allos. Once they reach the max pack size of 15 and more allos are introduced your original 15 allos and the new allos will form different packs. Hope this helps you understand allosaurus pack behaviors and pack animal behavior in the game in general as a whole. Thanks for reading.
