we were talking about this and seems we didnt have the answer as to how one acquires radiance gear that is not part of the 'rad' set vs how you get all radiance gear that is part of the set

so i got an answer to this question and essentially here is it

Doing each instance the 'hard' way gives the barter coin for radiance gear. the barter coins for the purple gear will drop from boss chests regardless.

FG = Fil Gashan = For Gloves
SixteentH = SHoulders
Go to the Forges to forge your suit of chest armor
Grand Stairs you get your stair-climbing Boots
Skumfil you will need your Hip Wader Leggings
Dark Delvings for your Head Lamp

Vile Maw Raid (which is why the gear even has so much radiance) to get the actual helm and shoulders for the full set. You'll be head and shoulders above everyone else if you can slay the Watcher in the Water.

cheers
