I have Nat's shadow, mark, soul and gaze for 4500
And also a nat reflection triffecta (doubledext 170/9as/29cd/5cd) no socket and
bloody footprints 800 for these (2pc = +7cc, 3pc achieved with rorg +20 disc <- works with U.E set)
As for the white transmogs idk who sells these, but I suggest putting up an offer.
People might be enticed enough to find them for you!
