Ruby Daggers - salvage the 15^50 and if the daggers survive, slap a highly salvageable inscription on it and expert salvage for crafting mat (you may get a ruby out if them)
Shadow Shield - I'm not sure. The req is a little high, the mods require both enchanted and stance - maybe a few k but I would get more opinions on it
FDS - salvage the +29 (sells for about 6k)
Ancient Scythe - 3-5k imo, there seem to be a lot on the market at the moment
