Both the Rangers of the North and of Ithilien have weak gear at the moment in the mod, even though in lore they are considered very powerful and deadly in battle. They are described as wearing earth-hued robes over their metal armor, this is an alternate recipe for it. The texture for Ithilien Ranger Armor would be identical to what it is now, but it would give iron level protection. As for the Ranger of the North Armor, it would also be iron-level protection, along with having new textures made by High King Ithilion. It would be crafted in the way shown in the screenshots, but with leggings, boots, ect for the other pieces. I hope you like this suggestion!
