Far more dangerous than the typical ~130k hp prime. Firstly his regular attacks hit a about twice as hard as most primes of his hp, striking me for ~4000 at 9000 armor. Has an untelegraphed instant grapple which pulls you to him. He has two telegraphed attacks, a small one that is easily avoided even just by backpedaling, not sure what it does, and an acid spray like attack, which deals incredible damage and will quickly melt your health pool. Even a single tick of it takes a chunk of hp so getting out of it immediately is paramount. Soloed as an engineer at 50, but lived with only a sliver of health at the end.
