Allosaurus

The Allosaurus (AL-uh-SAWR-us), or sometimes referred to as just Allo, is one of the Creatures in ARK: Survival Evolved.

Behavior
The Allosaurus is an extremely aggressive and dangerous predator, even more so when accompanied by its ever-present pack mates. Approach with caution - you may not always have visual on its nearby allies when approaching a singular Allosaurus.

Pack
Allosaurus always spawn in packs of 3, but packs will merge if they encounter each other. As long as a pack has 3 or more Allosaurus in it, the Allosaurus with the highest level will receive a pack boost, which can be identified by a glowing red-orange aura, similar to that of an. The pack boost applies to both wild and tamed Allosaurus and provides the following benefits: These buffs only apply to the Allosaurus with the Alpha Boost. However, in larger packs, multiple Allosaurus can sometimes become the Alpha.
 * Increases damage done by 50%
 * Reduces damage taken by 25%
 * An extra attack (default ) that slows the target and does bleeding damage
 * The ability to roar while tamed and mounted (default ) When the Alpha roars, the others in its pack will also roar.

Appearance
The Allosaurus is similar in appearance to the and the, with a few key differences. The Allosaurus is larger than the Carnotaurus, with longer arms, scattered plates and osteoderms on its head and back, and crests above its eyes. The alpha Allosaurus can be easily identified by its glowing red-orange aura (although take care that you haven't actually spotted an Alpha Predator).

Guaranteed Special Loot
The Allosaurus Brain can be found in the corpse's inventory or in the inventory of a tamed creature that killed it.

KO Strategy
The Allosaurus has high torpor, similar to a, but tames quickly once knocked unconscious. The best way to take on an Allosaurus is to single out a solitary animal from its pack. Be careful not to kill the others while taming it, though, because lone Allosaurus will run away in search of a new pack if the old one is killed off. To combat this, the target Allosaurus should be lured into an enclosure and properly secured before taking on the rest of its pack. This strategy, in particular, is useful if you want to tame the alpha Allosaurus, as separating and killing its pack mates will remove its Alpha buff, weakening it significantly. Be careful, as higher levels are easy to kill with Bows and Crossbows if you do not pause between shots. Taming more than one Allosaurus at once is risky.

Solo attempts require a very careful approach: not only is attacking a pack of Allosaurus by yourself unwise, but the areas where Allosaurus spawn are also likely to be crawling with plenty of other dangerous predators. The best way to do this is to position yourself on a tall rock, preferably landed on by a flyer, to protect you from their attacks. After an Allosaurus has been hit by your Tranquilizer Dart or Tranquilizer Arrow, it and the rest of its pack will become aggressive towards you. Continue shooting, making sure to aim for the head and pause between shots, especially when using a Crossbow. You should be sure to kill the other Allosaurus (as well as any nearby predators) while you are in relative safety. Once your target's torpor reaches a high enough level, it will turn and flee. Be wary, as they could either run off entirely or run around in circles. As long as the Allosaurus stays nearby, continue to shoot it from the safety of your rock. If it turns tail and flees out of range, you can either chase it down and shoot it from the back of a or run it down with an, landing each time you have an opportunity to shoot. Obviously, the latter option carries its own risks. Occasionally a pair of Allosaurus will spawn inside of each other and are unable to move. Once the other Allosaurus is dead/unconscious, the two that are stuck together can be knocked out at your leisure.

If you are able to isolate a high-level Allosaurus and remove the alpha status from it, you can ride on a burly mount that still allows the use of weapons, such as a or, then tank its damage while pelting it with tranq arrows/darts. A singular Allosaurus only hits as hard as a. Keep in mind that the Allosaurus will start running when its torpor gets high so it's advised to have a mount that can keep up. If taming on foot and without a trap, The gas attack of the can make an Allosaurus unable to sprint, making a knockout much easier.

Combat
This section describes how to fight against the Allosaurus.

General
Don't attempt to take out the pack leader first: take out the others and the leader will lose its Alpha boost. If the pack has 3 or more members, then killing the pack leader will just promote a different one to Alpha status until there are less than two left.

Strategy
Taking on an entire pack of Allosaurus is unwise. It is best to attack them one at a time using ranged weapons. This can also be done by picking one up with a Wyvern or Quetzal and moving it away from its packmates. Another approach is to overwhelm them with superior numbers by leading a pack of your own into the fight- just be careful to not be singled out or get in the way of the alpha. Attacking an Allosaurus head on is a bad idea due to the bleed ability which slows your Dinos.

Weaponry
Strong melee damage and a devastating knockback effect means that ranged weapons are extremely helpful for taking on an Allosaurus.

Dangers
A single Allosaurus is dangerous; a pack of Allosaurus is lethal. The bleed effect inflicted by an alpha Allosaurus will ensure that survivors who manage to escape from a fight will continue taking damage, so it's best to cut your losses early if you think you might lose. Their jack-of-all-trades approach to speed and power along with their pack mentality makes most conflicts a losing fight from the get-go. Additionally, wild Allosaurus runs 57.4% faster than normal survivors, so at least 39 level-ups on Movement Speed (158.5% Speed) are required to outrun one.

Weakness
Compared to similarly sized carnivores such as the, a single Allosaurus does not have a lot of health. The exception to this is the alpha Allosaurus, which takes 20% less damage, but that buff can be removed by killing its packmates.

Utility
The Allosaurus is an excellent mount for varying purposes, both on its own and with a pack. In terms of stats, it tends to form the middle ground between the smaller carnivores and the larger apex predators, but still has the utility that makes it an excellent addition for end-game content. Below are comparisons to lines up with other carnivorous tames.


 * Despite Helena's buttering of its smaller competition in the Dossier, compared to a : the Allosaurus is almost superior. The Allosaurus possesses a faster base movement speed than its smaller rival, and while the base damage of the Carnotaurus is the same as the Allosaurus's base damage, its high attack speed and access to a pack buff allows the Allosaurus to deal much more damage per second with its primary bite attack. The Carnotaurus does, however, have a few advantages that evens the playing field between itself and the Allosaurus. The Carnotaurus possesses a much slower stamina drain compared to the Allosaurus, and it doesn't require other Carnotaurus to be present in order to use its secondary attack, which inflicts the Bleeding! status effect. Their bleeds, however, deal the same amount of damage over the same time period.


 * Compared to a, it deals less Damage per Second, has less Health and a smaller Range of attack, but it does have a faster movement speed, and can deal almost as much Damage when given the Pack Leader buff. When that's combined with its smaller size, it makes Allosaurus more efficient when fighting in a large group; able to more effectively surround the opponent, with less chance of clumping up together and blocking their fellows from the fight.


 * Compared to the, Allosaurus deal a slightly higher amount of damage and has a much greater durability, especially with the Pack Leader boost (even though have a pack bonus that bolsters all that are in the pack, the Allosaurus has a much higher base health and the ability to utilize saddles. DPS discrepancies are made up for with the pack leader's gnash attack  when facing off against larger foes where this matters.) On the downside, Allosaurus are less agile than Direwolves, cannot jump, and are much more likely to get stuck on trees or other obstacles, though Allosaurus have a higher general sprinting speed. Finally, they spawn more rarely, in lower numbers and are more difficult to tame, so it will take more time to assemble a pack of any given size, as well as start a breeding program.

Roles

 * Combat Specialist: The Allosaurus can be utilized in a variety of different roles for combat, primarily centered around its pack-related abilities; able to take on opponents and employ strategies that harder hitters such as Rexes and Spinos would find difficult or are incapable of handling. That being said, Allosaurs can still benefit from the added power of their larger counterparts, who might run and hit a little slower, but deal more base damage at once over a larger area, have more health potential for the tank role, and suffer less from the knockback of other large opponents. Despite the many advantages their larger cousins have over them, Allosaurs are are not to be overlooked, as they bring many unique benefits of their own to the table. For this role; level primarily and.
 * Pack Fighter: On its own, a single Allosaur is most certainly outclassed by its larger cousins, but while one Rex, Spino, or Yutyrannus would have an Allosaur at a disadvantage, the tables can quickly turn if more than one Allosaur enters into the fray; as the true strength of the Allosaur lays not in the sheer stomping power of a single individual, but in their ability to hit more quickly, surround an enemy more effectively, and the mechanics of their pack dynamic. When in a group of two to three, the highest leveled Allosaur will receive the Pack Leader Buff; which comes with a 33% increase in attack damage and unlocks two additional abilities that were previously unavailable to it. The first of which is the ability to roar, which triggers its other pack members to do the same. While the roar has minor intimidation and aesthetic purposes, it does have a function; allowing you to identify which other Allosaurs are in the pack with the alpha, if there are more than two other Allosaurs present. The other unlocked ability, and by far the most potent, is the access to a secondary attack which, although it deals slightly less damage initially than the standard bite attack, inflicts one of the most dangerous status effects in the game: Gashed. There are multiple versions of this status effect, all of which bleed 5% of the victim's health over a duration. The Allo's version is by far the slowest, taking 10 seconds to drain the 5% of health from the target, but it comes with a bonus effect no other version of Gashed has: for the 10 second duration, the victim is slowed to a crawling pace. While this ability is useless against Bosses and Structures, as they are immune to status effects, Gashed can be inflicted on virtually any other target in the game. Due to the strength of their pack dynamics, having more than one alpha is always advantageous; giving your party multiple Allosaurs with a 33% increase in damage output and the ability to inflict Gashed, but there are requirements that need to be met in order to do this. To have multiple alphas, the first, and every alpha following it, must have at least two lower leveled Allosaurs to complete its pack triangle. Meaning if you have thirty Allosaurs, you can have up to ten Pack Leaders, and so on.
 * Slayer: With a pack of Allosaurs and the ability to inflict Gashed under your belt, this Dino is capable of absolutely shredding enemies that even a group of high leveled Rexes would struggle or find impossible to bring down. While the Allo's Gashed already bleeds 5% of a victim's health and slows them to a crawl for every second it remains active, it comes with a truly potent final benefit: Gashed ignores armor ratings. Various other top tier fighters like the Rex may be able to hit harder, but they can't hit through armor; making the Allosaur truly devastating against high-health and heavily armored opponents, reducing even the most lengthy of fights into a mere scuffle. To make the most out of your Allosaurus pack for this role, depending on the opponent you intend to take down, it's a good idea to bring two different support Dinos to aid you in your endeavor; a Yutyrannus set to auto-courage to provide both a resistance and a damage buff, and a Daeodon for healing.
 * If you want quicker and deadlier bleed damage, Deinonychus can be brought in to support your Allosaurus pack. Its bleed drains 0.3% health over 7 seconds, but can be stacked on top of itself up to 5 times.
 * Carnotaurus's Gnashed does not stack with Allo's, but their damage outputs are equal. However, Thylacoleo's Gnashed deals the same damage in shorter time (over 5 seconds rather than 10) and is preferred by the game.
 * Alpha-Slayer: Whether it's for getting rid of them as mere pests, killing them for the massive amount of Raw Prime Meat they're worth, collecting their relevant Trophies, or leveling your Chibi-Pets; a pack of Allosauruses makes slaughtering Alpha Creatures a walk in the park, provided you remember to keep hitting them with your Pack Leader's Gnashed attack.
 * Giga-Slayer: One of the most dangerous and unnerving opponents outside of Boss Battles, taking on a wild, and occasionally a high-level tamed Giganotosaurus, head-on is more often than naught considered suicide. Both the wild and tamed varieties sport an extremely high damaged output, but one is much more dangerous than the other. The former is notorious for not only being a heavy-hitter that ignores armor, but wild Gigas, on top of having an outrageously high health pool, are capable of inflicting the Gnashed status effect, just like Allosaurs. This makes wild Gigas an opponent that most people would rather avoid entirely. The latter also ignores armor when attacking, but unlike its wild counterpart, tamed Gigas have the potential to hit much harder per single bite. They also cannot inflict Gnashed and are crippled in terms of health; unimprinted tamed Gigas can have roughly up to 18k health, and fully imprinted Gigas can have roughly up to 36k health (mutations withstanding), while wild Gigas have over 80k. For both a tamed and wild Giga, each comes with separate risks, but both require the same solution; the aforementioned support team of a Yutyrannus and a Daeodon are essential: for both the courage roar and the healing. The wild Giga's Gnashed bleeds the maximum 5% of health twice as quickly as the Allo's Gnashed, but multiple Allosaurs hammering the Giga with their bite attacks can make up for the Allo's slower bleed effect. To kill the wild Giga, you merely need to survive its normal melee attacks longer than it can yours (saddle armor, Yuty courage roar, and Daeodon healing all contribute to this), while keeping your Gnashed constantly afflicted on it, and in about 100 seconds more or less: it will be dead. In the case of tamed Gigas, the problem is specifically surviving the massive damage output they are capable of dishing out, while out-damaging it in turn. Wild Gigas can be felled with a small group of just three Allosaurs, one Yutyrannus, and one Daeodon; for a tamed Giga, you may need to bring a much larger party to ensure enough of your tames survive to either out-damage it outright or keep Gnashed active long enough for it to die. Finally, the last thing to be concerned about is triggering the Giga's rage reaction, which makes its attacks even more punishing, something that can be lethal when triggered against a tamed individual. Keeping your party small when killing a wild Giga will ensure the rage reaction isn't triggered, but the requirement of sending a larger party against a tamed Giga may inevitably deal enough damage to enrage it, in which case your losses will be more significant.
 * Titanosaur-Slayer: With a pack of Allosaurs, A fight against a Titanosaur, wild or tamed, plays out roughly the same, with only a few minor differences. A wild Titanosaur will have no additional armor from a saddle, and no other creatures to really worry about while fighting it. A tamed Titanosaur on the other hand will have the increased armor provided by the saddle and more than likely allied tamed dinos assisting its effort to assault your tribe. Both are a particularly unpleasant battle, perhaps even more so than a Giga, but one that the Allosaurs can win with enough effort put into it. For starters: the Titanosaur's absolutely massive health pool. Afflicting Gnashed against a Titanosaur will guarantee its death in about 2 minutes, but the trouble with Titanosaurs is keeping Gnash afflicted for that long a duration. Allosaurs are smaller than their larger theropod cousins, and suffer more from the knockback of the Titanosaur's stomping attacks, which make it difficult to continuously hit it; because of this, the Titanosaur can eventually overpower and kill your Allosaurs before Gnashed finishes the job, while you struggle to keep landing your hits on it. For this battle, just like with a tamed Giga, you're going to need plenty of reinforcements with multiple Pack Leaders to make sure Gnashed completes its purpose. Depending on how many Allosaurs you have in the fray, a Daeodon and Yutyrannus aren't necessarily required, but are still a good idea. Likewise, some help from some larger tames like Rexes and Gigas is also valuable, especially against a tamed Titanosaur and its tribe. For this role, the support of a ridden Thylacoleo, with its ability to jump through the Titanosaur's knockback and land a bite with its quicker-bleeding Gnashed, would be invaluable.
 * Golem-Slayer: Due to their incredibly high armor and damage resistances, most tames short of a Giga find the territorial and problematic Rock Elementals an impossible feat to tackle; quickly elevating both wild and enemy tamed Golems into a serious nuisance if they're found in your vicinity. A pack of Allosaurs and their Gnashed ability once again comes to the rescue, and turns a difficult encounter into a feasible fight. For this Slayer target, if there are no other threats to worry about, all you'll need are just your Allosaurs, as most Golems won't be able to compete with the damage Gnashed inflicts on them to pose a threat to you.
 * Deathworm-Slayer: While not a role that Allosaurs are specifically required for, they do indeed make the task of felling the dangerous Deathworms much easier, particularly the Alpha worms. The worms themselves are not as dangerous as Gigas or Titanosaurs, and certainly don't have the same armor as Elementals, but they have a high health pool and deal a good amount of damage. For normal worms, a small pack of Allosaurs will do just fine, though for alpha worms, a larger pack, or a small pack used alongside other large-class predators, would be a good idea. Yutyrannus and Daeodon support are optional for this role; unrequired for single Deathworm battles, but if you intend to hunt multiple worms, they are invaluable.
 * Reaper-Slayer: While the only maps they would naturally meet on would be Extinction and Genesis: Part 2, and only then would you encounter the corrupted variety; corrupted or uncorrupted, Allosaurs are more than capable of handling Reapers if they ever cross paths. Normally, the presence of Charge Light is required to weaken an uncorrupted Reaper's damage resistances enough to kill it, but with Gnashed on their side, Allosaurs can completely negate the need for Charge Light. The light buff it is still recommended however, so that their normal bite attack can supplement Gnashed. Corrupted Reapers on the other hand, while still mighty foes, don't have the same resistances as their uncorrupted counterparts, and so make for easier targets. The only danger to be wary of is the Reaper's tail swipe attack, which can potentially be lethal; knocking your ridden Allosaur off a steep cliff or into various environmental hazards, such as Extinction's sulfur pools. Support Dinos like the Yuty and Daeodon are largely unrequired.
 * Enraged-Slayer: During the process of defending Orbital Supply Drops, you will be exposed to increasing waves of dangerous corrupted enemies, some of which can be very overwhelming depending on the Drop's difficulty level. The Corrupted will come in vast numbers and extremely high levels, to the point that even a high-level imprinted Giga can be overwhelmed. None embody this threat more so than the two varieties of Enraged Creatures, which are essentially Alpha varieties of Tek Rexes and Trikes. Both of these creatures boast incredibly high health, damage output, damage resistance, and armor, to the point that even the most well-bred Giga can be stuck spending well over several minutes trying to bring them down. This is where the Allosaur comes into play: best used alongside other specialized Supply Drop defenders, a pack of Allosaurs and their Gnashed bite can take the edge off the most stubborn of these encounters. Just as with most of these Slayer role targets, you'll want to bring Yutyrannus and Daeodon, though in the case of Orbital Supply Drops, odds are you were going to bring them anyway.
 * Brute-Slayer: A similar threat to the Enraged Creatures of Extinction, the Brute Creatures of Genesis are a nasty challenge; boasting similar damage output, health pools, and resistances, creatures that inflict Gnashed like the Allosaur are essentially required. Depending on the Brute Creature in question, bringing Yutyrannus and Daeodon along for the ride are generally a good idea.
 * DodoRex-Slayer: Killing a DodoRex is a daunting task, can't even be done with couple of Rexes or even Gigas, 2 Allos is enough to slay a DodoRex, its bleed not only just slow down their movement speed, it also slows down their turning speed, allowing Allosaurus to tail riding it with ease, it is recommended to feed them Wyvern Milk before engaging so your Allosaurus won't get killed by DodoRex's burning debuff.
 * Boss Fighter: While Allosaurs are ideal for slaying various difficult overland creatures as previously stated, when it comes to Boss Creatures, this is where they begin to fall behind the competition of their larger rivals. Since bosses are immune to status effects, Gnashed cannot be applied, and so generally the tankier, heavier hitters like Rexes are better fitted to the role. That is not to say, however, Allosaurs should be excluded from this category. While they might struggle with the likes of the Dragon; if you have not acquired Rexes and Yutyrannus yet: Allosaurs are more than capable of filling the gap, and taking on Broodmother Lysrix and the Megapithecus. That being said, there is one boss that they are able to excel against where most struggle: the Manticore. While the Manticore itself is immune to the Allo's Gnashed, compared to other Bosses, it tends to have much lower health and durability, allowing the Allosaurs to pummel it when it lands. Furthermore, during the fight, Rock Elementals and Deathworms will spawn in the Manticore's Arena; two creatures that Allosaurs have a distinct advantage over, as they are not immune to the Gnashed effect.
 * Caver: Because of the Allo's small hitbox, it is able to access some caves, like the Upper South Cave, and complete them without the use of a Cryopod. For the caves that it can access, the Allosaurus makes an excellent choice thanks to its large size. Since it's designated as a large-class tame, nearly all cave creatures will perceive it as too dangerous to attack, enabling easy travel from point A to point B to reach the artifact. If conflict ever does occur, its health and damage is more than enough to deal with cave threats (Unable to do any cave on Mobile).
 * Travel: As is the case with all large-class predators, the vast majority of wild creatures will opt to leave the Allosaurus alone, which makes them great for traveling through dangerous terrain in relative peace. They also boast a decent movement speed and weight comparable to a (Level Stamina and Weight). A high-level Allosaurus can also prove to be a very powerful creature, and combined with its speed, travel can be relatively safe as most threats will be manageable. Don't get too ahead of yourself, however, as a singular Allosaurus is still outclassed by creatures like  a Yutyrannus or Rex. It is best to avoid larger creatures like this, which shouldn't be a problem with an Allosaurus.

Notes/Trivia

 * On PS4, Xbox, and PC, there's a chance that a pack of Allosaurus will spawn inside each other (usually with a pair) and if hit (multiple times for PC), they will literally disappear.
 * Overlapped Allosaurus cannot move by themselves, making them easy targets to ranged weaponry and weaponry that doesn't have knockback.
 * The Allosaurus dossier was revealed on August 26, 2015
 * Sometimes when there are four or more Allosaurus in a pack, more than one Allosaurus receives an Alpha boost.
 * Despite the dossier stating it is slower than the, the Allosaurus actually has a faster sprint. It does, however, lose stamina faster than the Carnotaurus does.
 * Whether it is intentional or not, it is often likely for the Alpha boost to be given to the highest level Allosaurus in a pair.
 * Allosaurus can be carried by the.
 * In ARK: Survival Evolved Mobile however, the Allosaurus cannot be picked up by a.
 * The Allosaurus has a different roar in its spotlight trailer than in the game. This is due to a sound change after the initial release, even though the current roar has the Trailer's roar in it, but it also included other dinosaur roars in the game.
 * The scientific name of Allosaurus therotribus means: 'Different lizard' 'Beast tribe'.
 * If there are 3 Allosauruses in a pack, usually two will spawn inside of each other, leaving one to wander around and kill. This is an effective way to tame two at once, once you get rid of the free Allosaurus.
 * The Allosaurus bears a similar resemblance to Metriacanthosaurus, which it is closely related to as well as other carnosaurs like and Neovenator, all of whom belong to the superfamily, Allosauroidea.
 * The roar of Allosaurus is combined with trailer Allosaurus roar and Island 359 Tyrannosaurus Rex roar.
 * Allosaurus will attack tamed large carnivores such as Rex, also attack other smaller carnivores like Raptor and Carno.
 * With the exception of a wild, , , , Corrupted creatures and other Allosaurus, Allosaurus will aggro on anything.
 * In the Extinction map, Allosaurus is almost completely solitary which could be truthful to Allosaurus behavior. However this is disputed as Allosaurus remains can be found in groups; perhaps they only congregated on means of killing prey.
 * A pack of 3-4 Allosaurus can quickly kill a or, use the pack Alpha's Gore attack  on the Titanosaur and then back away to avoid the Titanosaur's attacks. Then after the "Gashed" debuff has ended, go in with the pack Alpha and use the Gore attack again. (Make sure to pull your pack away from the Titanosaur as well!)
 * While most creatures in Helena's notes have a saddle and check mark to let other survivors know the creature can be ridden, Allosaurus is one of the few that doesn't have a saddle or check mark in the art that Helena put in her notes.
 * The Allosaurus could have been one of the creatures that inhabited the ARK known as Aberration. While other creatures survived becoming mutated by the elements and the radiation from the damaged ARK, Allosaurus like many of the other large creatures couldn't adapt to survive in the new environment.
 * The alpha Allosaurus' secondary attack is based on a theory that the real animal would use its head like a hatchet, slamming their teeth repeatedly into prey. This is likely because their skull is resilient enough to withstand the impact it drives into its prey, Allosaurus may have surprisingly weak bite but it sure has the widest mouth out of any dinosaurs, they can open its mouth for around 92 degrees.
