The Cobalt subset of the Blacksmithing tradeskill is a Plate armor collection based around Defense. This makes it of most interest to Paladin, Warrior, and Death Knight tanks in Player vs Environment (PvE) scenarios.
Consisting of 8 pieces of armor it is a fairly complete gear set, while not being an actual Set. The cobalt set is easy to make and obtain at level 70, allowing the player to enter beginner Northrend instances as adequately geared tanks, which are important to the tank and spank nature of five man dungeons.
The whole set gives 122 defense at level 70, yielding 4.88% additional chance each for a dodge, block, or parry, as well as a 4.88% decrease in crit chance from mobs on the player. The health gained from the full set is 3620. Adding the cheap and easy to obtain Borean Armor Kit and applying it to all applicable pieces brings the total health bonus up to 4340.
