This may be a dumb question but I can't figure it out so I'll ask anyway. So I've noticed that most weapons have some sort of elemental damage *void and so on* the type is to the left in the weapon's upgrade menu. But I can never upgrade that tab or activate it. Is this because it's already activated or is there something I need to do? Please help?
