Do Gen 3 Legendary Variants require you to do the entire chain for every weapon, or just the first one?

[HeliosMagi.9867]

Just made my first Aurene Legendary weapon, and there's something about the variants I'm not clear on. For say the Primordus variant, I have to buy 4 scale splinters, combine them to unlock a collection, then complete the collection to unlock the ability to buy an Uncharged Fragment of Prismatic Fire, which I have to charge by clearing Dragonstorm, then use the now Charged Fragment to unlock the Primordus skin for my weapon. What I want to know is if I make a different Aurene weapon afterwards and want the Primordus skin for that one too, do I have to do that entire chain all over again, or will it let me skip to buying the Uncharged Fragment since I already unlocked the ability to purchase it from the first time?

You have to do it for every weapon.    so if you made the axe version, you only get that skin unlocked.   have to repeat the process each time for each weapon/variant.
