I can see your point. I don't want to completely shut out magic with his interactions. I want to make it hard to use it effectively against him while making him worthy as a person the desparate people of the Silver Sun would call upon. This way seemed like a good fit that could use story telling as well as mechanics to deal with. I have thought of several ways you could counter him while still using magic. The armor would protect him from direct magic, meaning magic attacks, or nullify enchantments at the time of impact without removing them entirely. However, if you were to throw a rock at him propelled by magic, or if you set a field on fire (normal fire anyway), or if you broke the ground underneath him then the armor would be much less effective. He is also still susceptible to other environmental changes such as heat, cold, dust, fog, etc. 

Using magical fire as an example: Lets say this magic fire cannot be extinguished, burns really hot, and will stick to anything. The armor would protect him from being burned by it if use directly against him, extinguish if thrown against him, and he would probably feel little heat. However, if the fire is use around him like as a deterrent, or trap him in a room and that is set on fire using it, then he would not be able to put it out, it'd continue to burn even if he stepped on it, the armor taking any damage that might have caused, and he would feel the heat put out by the flames. He would not be burned by touching the fire, he'd be burned because he is really close to a heat source.
