I know you've gotten this question before...

[Sheepss]

Is there any advantage of being a Bluful weapon wise or other wise?
'Nother question...what exactly are "Cards"? Can you use them more than once? Are they good? etc...

THANKS!

Bluefull is typically a good ID for hunter weapons. If you want to find lots of Partisan-class weapons like Brionacs (among other things), this ID is for you.

As for cards, do you mean the new weapon type like the Talis? They're just like any other weapon. You have unlimited use of them.
