And magical creatures,
My character, which I am planing on being on of the tribal race, will know how to make armor and it will provide protection and enhancement, because they don't really have any magical parts that can be used for powerful armor. I think that will help with limiting it in the begining. Armor has to be changed every, so often or they have to wait a long period of time, about a month-ish, before the armor's power begins to wayne, but leaving it on the certain amount of time will increase the effect and the user will gain more animalistic traits and features while wearing it that long.
