You can also get certain tome mats from Peisteskin/Boarskin Treasure maps, which as of the 2.5 patch HQ versions can now land in the loot pool. I got 16 HQ harden sap from my map runs a few days ago. HQ Scheelite would be awesome but I'm sure they don't want to make the Lucis tools *too* easy to get.
