HW stuffs are breakable but desynth lvl70 is too low, move onto old SOL tomes gear, iLvl100 stuff you got from Rowena's. if you have luck with that, roll with it,

If not, Hardmode dungeon WVR drops might be better, but you'll need to run Sastasha Hard etc etc so leveling from those drops could take a while.
