The only thing the decrease in category doesn't apply for is the proficiency required to not apply the armor check penalty to your attack rolls.
So yes, you can wear a mithral breastplate as a first level magus and have no ASF as a result of it.
Thanks for the quick reply. I am working around the limitations of Improvised Weapons as a kind of personal challenge. Arcane Strike to make the weapon magical to overcome DR (and add damage), items of special materials to overcome DR (worst case arrows are improvised daggers), buff/utility from Feral Hunter and spellstrike with Magus to deal decent damage. To say the least this is probably one of the most interesting builds I have done and that is not counting the amusement value of hitting people with random objects (Android Arm, Folding Chair, Shovel, etc).
With no money going towards my weapons I was going to focus primarily on buffing my AC and stats out. So this was good to figure out for saving up the 4k for the Medium Mithril cost.
