Manaweave armor is cool, but impractical late-game.
Netherite is useless in Botania.
I propose a solution: Plated manaweave.
By applying netherite to manaweave, you would plate it, quintupling its durability and doubling its armor points (plus one additional for chestplate and leggings), while preserving its special properties.
The armor would still be inferior to terrasteel/diamond/netherite at 16 armor points, but would be more viable later in the game. It would not otherwise be changed by plating.
Additionally, I think an accessory (probably a ring) crafted with netherite that did something such as give +2 armor points would be useful for stacking with this, but it's not really the main idea of this post.
