MAgic negating metal: WEAR A HELMET OF MAGEBANE!!!
[/quote]

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.
