Guild Wars 2

I just cleared whole story line for 2nd character.

I got another ley line infused stone and vial of sacred glacial water
but did get phantasmal residue from last instance.

am i bugged or phantasmal residue meant to be one time reward?

I got it twice on one character, but I suspect that was a bug.

That said, why do you need more than one? Once you’ve crafted the backpiece, it’ll be available to all of your characters via the skin wardrobe.
