New enchatment for netherite in the deep dark biome

I love the ideia of netherite, it gives a new challeging objective to the game but adding a new ore that netherite transforms into seems repetitive. The best next thing should be a new original enchatment only netherite can hold. The warden will be the big focal point of the deep dark so I think he should guard some structure that containes only one book with this enchatment. There could 3 different enchantments, one for armour, one for the sword and one for the rest of the tools. This way you need to explore the deep dark a lot with the objective of upgrading all of your gear. What the enchatment could do I'm not sure, comment what you think is best!
