The files to edit are thing_armory.dat, and the ddi_armor.user

thing_armory.dat has the mappings from Armor to Proficiency.
ddi_armor.user has the armors themselves.

In essence, remove the tag for ArmorType from the armor, because they are special armors, the armor tag effecitvely makes them count as (for things like the advanced plate and chain armors that come at higher levels) then fix the Armor Proficiency for Spiked Plate by editing thing_armory.dat and changing the armor apSpiked is for from arSpikePl to arSpikePla
