The most amazing Dino to take down Rockwell because they are so buffed in aberration all you need is a shotgun and a bunch of megas. They are quite easy to tame and I usually just make a box that they walk in to and then I start tranqin him till he goes down. I let him starve and he wakes up if he hasn’t starved out then I put in food or knock him out again till it has starved enough
