There doesn't currently seem to be any way to configure these, and it would be nice if there was a way to modify how these work or disable/enable specific ones for balance concerns. In particular the "Takeoff!" spell feels extremely strong to find early on and as an occasional pack maker I'd like a way to tone that down without barring people from making their own flight spells once they hit tier 3.
