The Pachycephalosaurus(pak-ee-SEF-uh-lo-SAWR-us), or simply Pachy, is one of the dinosaurs in ARK: Survival Evolved.
Basic Info
Dossier
This section is intended to be an exact copy of what the survivor Helena Walker, the author of the dossiers, has written. There may be some discrepancies between this text and the in-game creature.
- Wild
Pachycephalosaurus is a bit of a conundrum. It is a very passive (even friendly) herbivore, common to much of the Island. At the same time, it is one of the most dangerous herbivores that I have yet encountered on the Island. Its charging headbutt is a display of sheer physical power, and can kill much more quickly than you might think. While Pachycephalosaurus is generally friendly, it has a short temper. Its fight-or-flight response always seems to choose "fight!" The Pachy becomes extremely aggressive once attacked. Additionally, it is an incredibly fast sprinter, so escaping from an enraged Pachy is very difficult.
- Domesticated
Pachycephalosaurus is an excellent battle-mount for those who want to ride a smaller, nimble combatant into the fray. Because of its particular musculature, it cannot effectively carry large quantities of resources. It can, however, move with brief magnificent bursts of speed, and its headbutt is simply devastating.
Behavior
The Pachy is passive unless provoked. They are rather slow when moving normally, but move very quickly when using their charge attack.
Appearance
Standing at a man's shoulder height and estimated at 4.5m long, this bipedal dinosaur possesses a thick bony dome on the skull and a beak for browsing vegetation.
This section displays the Pachy's natural colors and regions. For demonstration, the regions below are colored red over an albino Pachy. The colored squares shown underneath each region's description are the colors that the Pachy will randomly spawn with to provide an overall range of its natural color scheme. Hover your cursor over a color to display its name and ID.
This information can be used to alter the Pachy's regions by entering cheat SetTargetDinoColor <ColorRegion> <ColorID> in the cheat console. For instance, cheat SetTargetDinoColor 0 6 would color the Pachy's "body" magenta.

Wild Stats Level-up
Type in values of a wild creature to see on which stats it's emphasized. Green values on a high-level creature are very good for breeding. If you have already tamed your creature you can try to recover the breeding stats with an external tool.[1]
The stat-calculator does not work in the mobile-view, see here for alternatives: Apps
Note that after the creature is tamed it gets bonuses on some stats depending on the taming effectiveness. This makes it hard to retrieve the levels on a tamed creature, so this tool is only for wild ones, but gives a first impression, how well the stats are distributed.

KO Strategy
While the Pachy does not have a lot of Topor, attacks on the head are nearly useless due to the headplate. If possible attacks should be focused on the body rather than the head. Thus having Pachy charge at you is a very dangerous situation. Luckily it is vulnerable to the Bola, making stopping it and flanking it with a Wooden Club easy.
Combat
This section describes how to fight against the Pachy.
General
The head of the Pachy reduces incoming damage by 87.5% and the rest of the body takes only normal damage. It is advised to kill or down(for taming) a Pachy before it closes distance with arrows or gunfire.
Strategy
Perching upon a stone whilst shooting at it with a bow/gun is a valid strategy, however, Pachys are commonly found in places where carnivores live. Therefore, climbing onto the rock might be dangerous. Once the Pachy reaches the player, it will headbutt the player relentlessly. During this process, it is difficult for the player to not hit the bony helmet on the Pachy's head, which causes a problem when fighting back.
Weaponry
Long ranged weapons and potentially a Pike can do the trick, as melee battles will subject the player to damage. A powerful mount can almost effortlessly kill a Pachy with a couple, or in some instances, a single chomp.
Dangers
The Pachy lowers their head in front of their body when attacking, giving themselves a damage-reducing shield. The attacks of the Pachy raise the target's torpor, potentially knocking it unconscious. Attempt to take care of the Pachy before the battle becomes physical, as many players, especially those of lower levels will be unprepared. Always keep an eye out for other Pachys in the area, or more dangerous animals. A casual Pachy-taming adventure can turn into a bloodbath if the players fail to stop a Carno or Rex from entering unnoticed. There is not much that can be done once larger predators arrive, only massive loss of life between helpful players and beloved animals.
Weakness
The Pachy has relatively little health. Try to override the damage output by a volley of arrows or bullets, or a powerful mount. If you ride a Beelzebufo into battle, use its tongue to knock it out and then simply kill it or tame it.
Utility
Roles
- Knocking-out: Both the Charge and Non-Charge attack increases a targets Torpor when hit. The induced torpor by the charged attack even gets a bonus of 3.5 to the already increased attack damage multiplicator of 1.7 compared to the regular attack, resulting in a 5.95 higher induced Torpor. Increases in a Pachy's damage will make for a more effective, and quicker, knock-out. If you use the Charge attack to assist in the process, increases in Melee Damage and Stamina will make for more efficiency. Speed does not influence the induced Torpor.
- Damage: Increases in Speed and Damage will make the Pachy a battering ram that can knock down Wooden buildings easily and knock out wild animals. More effective in groups with Mate Boost. Currently there seems to be a problem with Pachys damaging wooden structures. While easily smashing thatch, a Pachy does not deal any damage to wooden structures (Level Health and Melee Damage, with some Stamina).
- War-Horse: Similar to Damage, the Pachy's Charge Attack is extremely efficient at damaging buildings especially in groups with Mate Boosts. Increases in Damage and Speed are required. The faster a Pachy is moving when it hits its target will increase the damage it gives out (Level Health and Melee Damage, with some Stamina).
- Travel: Pachy's Charge Attack can bring them up to extremely high speeds, but they are easy to stop (by land or pack attacks) and they are unable to turn during this. Increases in Stamina and Speed will give you a swift steed.
