I think it's exactly where it needs to be. 6x damage is perfect. It shouldn't be 3x for obvious reasons. It should be 4x because if aclyophage symbiote and 5x isn't that much of an upgrade. 6 is perfect. Not to OP but just enough bonus damage to make it a great helmet. It's not wiping out bosses in one hit or anything stupid like that (I think I heard it nearly kills death singer on normal.) but it does a significant amount of damage that makes you feel like you didn't waste your Golden Gun
