lower aa cost?
the + on the weapon stay?
you get the crystal back?

thamks in advance for the help
+ stays, no ctystal back. doesnt matter what blacksmith you use.
Black marketeer can remove SA for about 50k AA
i think blacksmitsh of mammon will do it for free, but that might only apply to c grade?
