Legendary?

White Wing Staff is Legendary, though it is questionable considering the only mention was a "white-winged" god was an inspiration. Mace of mercy is...well...more rather ancient considering Slates are enchanted stone entities, so let's throw that in the pile.

...now as for the Bracer Knuckle, It's not legendary if NPCs like Mina and Keane have them...then again...look at Price and his random Caladbolg...He probably obtained one in his travels while going into varies places of Uladh. My personal opinion on this matter that it is not legendary, though the fact that Gold is used to repair it makes it even more less legendary considering normal blacksmiths and weapon shops can repair it just fine, in where fomorian weapons require the special care of Fomors to repair. I'm sure they could easily repair human made weapons though...
