I understand it can't be infused with an updated one because of the intrinsic perk. But this won't even let me and fuse it with anything even with upgrade materials. I went to r/Destiny2 sub reddit the other day and was told [quote]Because of the under-the-hood rework weapons with origin traits got, they aren't the same as older versions. That's why there are multiple versions of the same weapons in collections.[/quote] And that the reason we can't is because there are two of them, and basically it's too much work... TLDR the BTW I have won't Infuse to any other weapon. I just want to use it to pump up the light level of another gun and it says it cannot do that. Even for an upgrade module.
