Am Armorsmith 500, and was tinkering with Discovery today to clear out the last few recipes.
Globs of Ectoplasm is showing 48(!) undiscovered items at 350+ though with no other ingredients flagged in my fairly extensive inventory. It's not linen, silk or gossamer patches (so not insignias I think) and I'm scratching my head about what these 48 recipes might be.
Thoughts much appreciated.
