sorry, and i was thinking of a magic that relies heavily on the persons imagination its called operator magic, it requires magic to activate and sustain, the user must understand ... lets say wind magic and then the person says "Operator magic: Burst mode" which then gives the armor that is created from nearby minerals of the users thought ( the armor must be made of one mineral or there will be weak points other than the neck)... if the mineral the user thinks of is not nearby it chooses a mineral close to the durability and strength of the one selected. please let me know if i need to go into more detail.
