[@Scio] With the physical letters angle, would it be Conjuration or Liberation, especially if it has effects that could possibly mimic some of the others (making a punch stronger seems like Enhancement), or would it just be chucked under Specialisation?

However, if he were to say, try and do something less physical instead ("Launch a concentrated beam of light directly in front of me with wavelength [insert here]"), how would the blocks work? Do they leave his mouth and then transform into things like that? And magic here works off some pool of energy right, so doing something like that should also be a bit draining?
