a forge

a new block that when used will allow you to customise you armour (adding size, decreasing size and gilding) this would add a new layer of customisation to minecraft, because i personally think minecraft does not have enough customisation plus this would add some personality to the type of armour you wear. you but this would only be available to iron and up. i think you could add other ores to the armour. like gold would grant immunity to piglins without wearing gold. but i think it would be crafted with a netherite ingot.
