Aquanium ore (Was: Aquanecium)

This is a new rare ore that can be found in every cave biome that have small lakes in them. This ore will be completely submerged by water, meaning that you will need to go into the water to mine the ore. The ore would work as a new type of tier and as decorative purposes. The new tier would be a combination of diamond armor and an Aquanium shard. The Aquanium shard would be a cyan scrap created by melting an Aquanium ore. The Aquanium tier would have a cyan tint, meaning that is more darker than diamond. The tier would be the same as diamond but it would give you 30 seconds of water breathing and would give you more resistance to water mobs such as drowned or guardians. The tools will be able to break blocks underwater at the same speed as breaking blocks outside of water and the Aquanium sword would be able to deal extra damage to underwater mobs in general.
