So I can craft some Zorah Beta gloves, and they have a skill called "Free Elem / Ammo Up". The Free Element skill says that it will unlock a weapons "hidden" element... I've yet to see a weapon with a greyed out element. Like all the Bows I use have an element, in fact ALL the bows in all the trees that have an element do not show them as being greyed out or in parentheses. The info I've found so far says that the skill will not add an element, just unlock an existing one. So... is this skill pointless?
Edit: Ah, nevermind, I see how it works. If the base weapon has an element, the skill isn't needed. But if the base weapon doesn't have an element, but gets on further down the upgrade path, then the Free Element skill is needed to unlock it. Example, the Ore Bow has no element to start with, but at Rarity 5 it gains Thunder, but its locked.
