Deepsteel

My idea is for a new type of metal called deepsteel that can only be found in the  deepslate layer, and mined with an iron pickax or better. It could be combined with amethyst in a similar way to netherite scraps and gold, but with less of each material. It would be then called gemsteel, and combined with diamond armor in the same way as netherite. It's protective statistics would be the same as netherite, but would increase melee damage instead of knockback resistance.
