Hello! This is part 4 of my suggestions!
1. Mail- I think that different kinds of Mail should be introduced. The mail could have the option to turn the image of the armor on and off giving the effect of it being "hidden" under your clothing. Iron mail- Default mail armor, this would cover half a hitpoint above regular iron chestplates. Golden mail-Same as iron, but it would be more decorative and would be a lot more durable. Dwarf-steel mail-same as the others, decorative and higher protection than dwarf-steel armor. Mithril mail-The strongest chestplate in the game, putting this on would give you the achievement "A kingly gift!"
2. Dwarven armor and weapons in the dead marshes- From the lotr wiki it says- "50,000 of Durin's folk helped the Last Alliance, and alone of the Dwarf clans none of that folk served Sauron." so I believe that weapons and armor from the dwarves of the Iron Hills. -Auraestus
