Ocean cave and Prismarine armor!

We should get a new type of armor called Prismarine armor, It's crafted with Prismarine Shards but it's not usable yet, you need to put it into a Smithing table and put prismarine crystal to make it functional, it give infinite water breathing, faster movement in water and faster mining, also remove water fog if you give the prismarine helmet a Prismarine rod (pls Mojang add it to complete the rod trio)
