Two, possibly related issues with this spell. First, in my spellbook it shows only as Stone Deaf without indicating the quality of the spell (which should be Expert, as I have scribed that). Second, it is not on the Ugrade list for researching. Does this spell actually improve in quality with the upgrades? Why can it not be researched? I notice the Grandmaster versions have been discovered.
it would be nice to see a grandmaster version with say 4 triggers of a stone skin, but who knows. chances are this will never happen
