New form of armour idea

I believe the time has come to bring on a new type of protection in Minecraft. With potion effects like instant damage, poison and weapon enchantments like fire aspect having little to no counters other then milk and water. I think it would be awesome to have a type of magic armour buff ( around the regular armour ) this magic armour could be use to decrease potion and enchantment effect as well as duration. This buff can be obtained by some sort of belt or ancient relic. And if brought into the game and finds to be to over powered the resistance could diminish. I believe this could open up a whole new field of Minecraft combat with more ideas around this field of magic and sorcery.
