Make Thaumaturgy and Jeweler do something!
 

I think these skills are still for sale and there are no gems or jewelery to identify. More drops anyone? I mean if the drops are stupid that is awesome too you know. Finding a ring that sells for like 200-300p like these books I read on the market stands say I should look for.

"Herein lies the details of an artifact Ring of Occidental Mages of Adornment which is worth ten times normal value"

Sense Magic, Sense Curse, Woodsman, Alchemy, and Smithery all have uses. Why not Thaumaturgy and Jeweler? Even if the experience is minimal it all helps mental. The only way mental is useful is if someone has learned Dust of Visibility and Water of Ruby for powerleveling to 110. Mental experience is hard to come by for those of us who can't read a level 30 book "Dust of Countermagic."

There are also no wands that could be made with alchemy. No wands I have had actually benefit you aside from looking different.
(not of course meaning ones with cast X number of spells X amount times)

I think certain weapons (like Glamdri and Carman) should allow you to cast with hotkeys.

Just throwing a few ideas out there.

Isn't Thaumaturgy basically to magic what Piety is to prayers?

Your thinking of a Legerdemain which grants you the Wizardry skill. Thaumaturgy identifies wands, or it's supposed to.
