Hyperius literally is invincible

Hello
I keep trying to kill lvl 72 hyperius and I just can’t it’s impossible for me I’ve tried everything so if anybody wants to help me kill him then feel free to messages me GT: The AfroNinja27
Thanks

As I said I’m down if more people come on

I’ve been farming him for search crystals on lv72, I’m using op8 hear though so he’s easy.

Message me if you still need help. I won’t be in until tomorrow though. It’s Dave90T
