Nordic Carved Armor requires a Smithing level of 50 and the Advanced Armors perk to create. Pieces can be upgraded with a quicksilver ingot at a workbench and also benefit from the Advanced Armors perk, which doubles the improvement.
In Fallout 3, Perks are bonuses of varying kinds that are earned after you successfully attain a new level. Each level you earn will not only allow you to dump skill points into your various skills, but will also allow you to choose an available Perk from the list given.
