Thaumaturgy Sorcery
I'll come back to this, but I wanted to record the idea for future inspiration (to myself).
If something can be accomplished with thaumaturgy, in Exalted, then it can probably be done even better by a more powerful effect fueled by sorcery. In particular, it seems to me that if wards can be created with thaumaturgy, then better wards could be created through sorcery.
