Shaders are not available for any of my Reverie Dawn Plate pieces, I've only confirmed on titan. In any menu where shaders could be applied there are no shaders listed at all in the shaders menu for any reverie dawn armor piece, only the "default shading" option is shown. Ornaments can be applied. I've only checked Titan, as its the only character I have reverie pieces for. I checked a sunset class item from Forsaken, and shaders were available. I do not have a Reverie Dawn class item from after the dungeon armor rework to check against.
