Overall Attack

Does anyone know how to get a scroll like this? Or is it just a wrongly worded mess-up by Nexon?

It is a visual glitch, the files apparently list it as +3 weapon defense, while the in game text is typoed to read as weapon attack.

No it does not add attack, just defense for that particular stat in question.
