Use a high level drake with lots of stam, (dont waste your time leveling up damage on your drake, it will be used for running) an ascendant shotgun with lots of shells, extra hazmat, and a buttload of Megalosaurus for actually fighting him. (The shotgun and drake are for fighting the tentacles)

He suffers from steroids
He is very good pet too

Rockwell can be found in the Rockwell arena beyond his designated terminal, I believe it’s beyond the Graves of the lost (or commonly called the Rock drake nests) but it’s somewhere there.
Also to fight Gamma Rockwell like any DLC boss you need the three artifacts.

How to fight Rockwell:
Firstly Rockwell is in the center of the arena, stantinary in a pool of molten element, please do note that whilst his five tentacles are up Rockwell can not take damage, he attacks by jetting out balls of energy that Beal area damage, electrifying the ground with a tentacle slam and summoning Nameless plus Elemental Repear kings.
To defeat him, you must destroy all tentacles before attacking his heart in the center, note that he can raise his tentacles again so you must repeat the proses.

Bring a light pet as around halfway into the fight he starts to spawn nameless and reapers

Dododex, why is Rockwell listed in Ragnorok? Please change this!

Stegos with 60+ armor saddles atleast 3 people at minimum shotguns 300-400 shots per person and 2-3 flak sets per person and 15-20 vegie cakes per stego walk around it and shotgun tentacles 200+ damage shotgun recommendation as its more effective

I have been looking for this guy for quite a while now and cant find him. Dont get me wrong he sounds like a cool boss but I just cant find him. like if you know how to find him and tell me please.

Yeah just saying Rockwell when he injected himself with fing to make him the boss Rockwell he made the guardians of the island and the valcano and he or helena sealed the cave and you needed to get the heads of the guardians in order to pass If you made it this far you know what happend next once you entered it but rockwell boss could be testing you until scorched earth I think
