As you level up you will find that rare armor starts to appear in the game on bandits and other humanoids The higher your level, the more you will start to find and the more it appears. First is dwarven, next is elven, and so on. I will advise you to aim for better armor though, such as dadric armor or glass armor.
the next best armour is adament.
A coat of mithril he was given out of Smaug's hoard.
There are six main types of light armour in Oblivion: Fur, Leather, Chainmail, Mithril, Elven and Glass. They are all leveled, so different armour will show up at different times depending on your level, although there are exceptions and three or more are often available at one time.
defeat the mithril man in crash site
Mithril, possibly Rune (rune is a sort of greeny-blue)
You have to download a mod, there is no halo armor in the game itself.
You can, if you use a mod.
daedric
Keep killing Mithril Man in Crash Site but it will take a while
It is either leather/steel or quest\enchanted armor or blades armor
No, no Bone Armor exists in game, without the assistance of a mod (modification).
Unfortunately, it's impossible.
