1.5k armor

"1.5k armor" usually refers to a set of armor that costs 1.5 Platinum (or 1,500 gold) plus common crafting materials and/or rare crafting materials, per piece, to craft. They can be crafted beginning in Droknar's Forge and have the best stats among their own type of armor. Note that even though "15k armor" sets exist, each 15k armor set has the same stats as one of the 1.5k armor sets.
