Habitat

Rockwell Arena, accessible via the Obelisks and/or the Terminal on Aberration

Rockwell (Or formerly known as Sir Edmund Rockwell) is the Boss in ARK: Survival Evolved's Expansion pack Aberration. He was one of the few explorers who had written Explorer Notes containing recipes before he went insane "ascending" with his Edmundium (simply known to villagers as Element) experiment, as evidenced by his notes in the Aberration Map.

Basic Info

The place to activate the teleporter to the Rockwell Arena depends on currently unknown conditions. For some players only the Terminal shows the summon icons, other players can see them also in the Obelisks on the surface or in loot crates.

Behavior

When you enter the Rockwell Arena, Rockwell's Tentacles will attempt to attack you by slamming into the ground, electrocuting the ground, and shooting balls of energy at you and your tames.

Appearance

This former explorer is a humanoid monstrosity with exposed organs, a malformed body, and many tentacles with element flowing through its body giving it a purple glow.

Color Scheme and Regions

The Rockwell always spawns with the same color scheme and has no color regions.

This means it is currently impossible to make alterations to the Rockwell's natural spawn colors.

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.

Rockwell (Gamma)

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.

Combat

General

Along with the Dragon, Overseer and King Titan, Rockwell is considered to be one of the most difficult bosses to beat (with only the King Titan being the most challenging of them all). Rockwell stands inside the middle of the arena with a single path to him, surrounded by both his tentacles and a pool of inaccessible pure molten Element. While his tentacles are up he can not be harmed. The arena is not irradiated, because of this feel free to bring any armor better than hazard suits to ensure survival.

Strategy

Destroy each of his tentacles before being able to attack his stunned body. Rinse and repeat until he is dead. The more mounted players fighting, the better the odds.

When the tentacles begin their AoE shock/dismount attack avoid it immediately and wait it out. It has a short wind-up animation and charge-up sound indicating when it's about to start. The attack can also be canceled if the tentacle is destroyed.

Nameless will begin spawning in, with a strong mount these can be dealt with.

Plant Species Z Fruits are not recommended as you can accidentally dismount and blind yourself with them. Charge Lantern could also work, however they are unreliable and inefficient when compared to any of the four lantern pets. You can use meks to kill Rockwell but to get the mek in you have to throw it out of the cryopod when you hear the whoosh of the boss fight .

Recommended Tames

NOTE that I used creatures that came from that map the boss was released on to make fair suggestions.

If you feel like adding creatures that's fair enough however don't add any that are exclusive to a Expansion Pack if those creatures aren't on the same corresponding map the boss is on or any free maps released with the base game. (ex. Velonasaur on The Island should not be suggested since you have to buy the Extinction expansion pack to get them and not everyone will be able to afford that Expansion Pack).

Unique creatures from maps like Ragnarok and Valguero and Expansion creatures that were used on that map (ex. Mantis used on Ragnarok and Valguero) however are exceptions since the players have instant access to them for free.

• Light pets such as the Bulbdog, Shinehorn, Featherlight and the Glowtail will all be effective and are recommended due to helping against the Nameless and Elemental Reaper minions.
• Due to Aberration not having Rex's for Rex Rushing Aberrant Megalosaurus can be used as a substitute instead thanks to it always being night on Aberration they will always have the night buff.
• A couple of Rock Drake can also be very effective due to being able to not only compete with the arenas Elemental Reaper minions but also doing increased damage against Nameless, the ability to turn invisible, allowing the rider to fire from the saddle while mounted, allows a passenger to ride on it as well, and they can also be equipped with a tek saddle.
• While not nearly as mobile, Aberrant Stegosaurus are often chosen as an alternative to the Rock Drake due to it's tankiness and ability to heal from Sweet Vegetable Cakes.
• Having a Reaper King can also be useful as a way to deal heavy damage once Rockwell is downed thanks to its increased stats when not around charge light making it a very strong tame.

Dangers

• Rockwell will often spew out purple energy balls at the target player, wounding anything around (including shoulder-mounted dinos) and inside of it with the exception of his tentacles. This includes the player while riding a mount, to be prepared for this bring multiple suits of armor and Medical Brew to increase your chances of survival. This projectile will also target camouflaged Rock Drakes. The darker the projectile color (with red being the most dangerous), the more damage it will do upon exploding.

• Shooting the projectiles will cause them to burst. Shooting it near other projectile will cause them to explode them as well, but if any survivor or dino comes into contact, they will get hit by it.

• He will also call out a constant wave of Nameless and a few Elemental Reaper Kings to defend him after he emerges from the Element Pool for the second time. The last time he emerges from the Element Pools, the aforementioned dinos will constantly spawn and could overwhelm every survivor and their dino, making killing Rockwell a priority to stop them from spawning.

• After losing a certain amount of health, Rockwell's tentacles start an electrification AoE attack. This attack dismounts, hinders, and damages players. Watch the tentacles and stay away from this attack which will be especially deadly when other creatures are nearby. You cannot remount in the electrified area.

Weakness

Edmund Rockwell has only one weakness to his health: His heart. It becomes exposed after all the tentacles are killed momentarily.

Elemental Reaper Kings are weaker than their other wild counterpart, making them very easy to kill. Despite this, to be able to kill them effectively, they must be affected by charge light.

Nameless spawns disregard presence of other enraged alphas, and transforms into them after a while. Unlike the ones outside the arena, these do not call for Subterranean Reaper King. Despite this, it's best not to underestimate them due to their swarm.

Other than his tentacles and his inability to move around, he does not possess any other weakness.

Dossier Code

There's an encoded message on the teaser dossier, which uses the same code as in Ascension. The message decodes to

“

"I am not a god. I am more than that. Infinitely more. I am everything. This world, this ARK, it is my body. " "I can feel every bit of it, every footstep of man or beast that falls upon my skin, and every root that digs into my flesh. They are all mine. Everything in this world happens only by my will. " "The ones who put me here have long since fled, but though I hate them, I accept their escape. It is their reward, for they placed me upon this throne. " "Yet should anyone else challenge me, they shall receive no mercy. My wrath will be swift and terrible, and my enemies will know only pain. I am everything. "

Notes/Trivia

• The boss was first introduced in the community crunch 111 on 2017-12-08.
• Rockwell was the Largest creature in the game until the Extinction Expansion Pack came out with the King Titan replacing Rockwell for that title.
• Unlike the other bosses, Rockwell's dossier appears purple in tint (perhaps due to Aberration's color and its theme of mutation/corruption), as opposed to the turquoise color associated with normal bosses. This shares a similarity in terms of different colors with King Titan and Alpha King Titan
• You can summon Rockwell at an Obelisk like other bosses. However, Rockwell possesses his own Terminal in the style of a Tek Cave.
• Rockwell is one of the only 2 bosses to have a tek cave with the other being the Overseer.
• Edmund Rockwell proclaims Element as Edmundium.
• Evidenced by the Explorer Notes, and by what happens in the boss fight, it appears that when Mei Yin and Helena banished Rockwell into the depths of Aberration, he somehow fell into the Guardian's chamber before assuming its place. This is likely how Rockwell states that he was "placed upon this throne". Since the Guardians are technically part of the ARK itself, this means Rockwell was connected to the programming and everything else which runs the station. This could easily explain what he means by saying the ARK is "his body".
• Evidenced by the same as above, Rockwell may have "taken over" Aberration. Granted the ARK was already damaged beforehand. This is evidenced upon his defeat in the boss fight, as there is a purple dome which seems to suddenly appear around the arena, that then begins to shatter and break apart, being replaced with a blue light, while showing the player various holograms. In a sense, Rockwell's defeat seems to trigger the ARK working again properly. Since Rockwell is technically a Guardian, he's now a complete autonomous part of the station, which will continue to summon him to be killed and to do battle with survivors again; a never-ending cycle of imprisonment which serves as a strangely poetic end for a man who became so corrupt.
• Out of all the known bosses, Rockwell is the only boss that remains stationary, if not invulnerable, until all his tentacles are destroyed.
• It seems that if an Overseer is completely destroyed, the ARK it is operating will slowly start to crumble and ultimately self-destruct. Helena, with the aid of Santiago, managed to prevent the ARK's self-destruction by hacking into the Obelisks and shutting them down. Right afterwards, Rockwell ascended with pure Element and transformed into a horrible monster of tentacles. He was eventually defeated by Mei Yin and Helena. Cast down into the depths of Aberration, Rockwell began to mutate into a living conductor of Element, therefore claiming his role as the new Overseer, which allowed the ARK to be stable.
• After Diana and company's Tek bomb completely destroyed the Overseer, the ARK suffered a malfunction. Afterwards, Rockwell injected himself with molten Element. He proceeded to attack the Tek city before fighting with Helena and Mei Yin. In this battle he created a pit out of anger. He fell down said pit into one of the Guardian chambers, claiming the role of the Overseer.
• When a Rockwell tentacle comes in contact with a dead Reaper's acid burn, it's temporarily stunned and left in a "t-pose" state until the effect wears off.
• On Extinction, if the King Titan is defeated on Alpha difficulty, a secret ending cutscene will play, revealing that even after being slain by your hand, Rockwell is still alive and now on Earth alongside the crash landed Aberration ARK and says as message to the player in a distorted mechanical voice, I AM COMING FOR YOU.
• The Dermis of Rockwell is obtainable by hitting him with a Taxidermy Tool from the platform where his chest is exposed as he is doing his death animation.
• A force tamed Rockwell does not and will not obey whistles.
• Rockwell is one of the only 2 characters the player meets with the other being Helena and he is the only one you fight against.
• Rockwell can be considered the Main Human Antagonist for Ark.
