[@DeltaV] What if I separated the abilities into distinct "modes?" Perhaps he has to transform into a draconic shape to use the draconic abilities, and can only use the sorcery in a frailer human form.

Perhaps, but if so I'd prefer for the swapping between the two to be a relatively time-consuming process, so they couldn't just swap back and forth at will for essentially the same effect as if there was no distinction.
