The problem: Magebane is rare, expensive, and making a helmet cover your head would be an unwieldy annoyance and finally, magebane is weak against the physical. So that noggin-cage won't protect you from a heavy stick. And given the variety of Psychomancers (Giant motherfuggin dragon man) getting smacked is a real possibility.
Depends how much magebane is needed. Hell you probably jist need some the size fo a penny and wrap it around your head with a cheap leather thong.
And again, IT'S MAGIC!!! It don't work like the real world. For all we know, a person's mind can be like a maze and you need time and energy to navigate it, not to mention fabricating a whole new purpose and altering people's intentions.
