Given August's limitations (I wouldn't call them fatal weaknesses per se given that his own carelessness was a bigger factor, unless for some reason magic coming from items really damages him that much, which would be really underwhelming), I really want to see Mashima clear up the nuances of caster vs holder magic (as if he cares, as if we all still care).

I mean, I get it that holder magic is less immediate than caster magic and that the medium/container may add something extra to the overall output, but in terms of magic power (assuming all magic is still commensurable and measurable in terms of a common magic unit) what prevents someone from using a caster magic spell to block or counter a holder magic spell?
