DE Here is a fix that would be nice.
This gun can't damage the Orb Mother Correctly.
I built it with no elemental bonus mods and used the cycling alt fire to attempt to have it cover multiple elements the Orb could be weak to. Unfortunitly the shots get reduced to "0" damage due to the orb being immune to status damage and the damage counts as status only damage with no physical projectile as I can only assume the damage is only added if the enemy can be proc'd.
If you put elemental mods on the Hystrix those mods or mod combinations count but not the whole guns gimic of being able to use multiple elements.
