Return of Reckoning

Hi all,

Where can I find lvl 50 Fragments for Talisman making?

My Talisman Making is 68 while my Salvaging is 79.
I ran out of lvl 50 fragments to make Talismans, but now I seem unable to get any more.
I tried farming lower level zones for items to salvage, but they seem to only give lvl 75 ...
