The Ancient Cobalt armor design is based on a version of Cobalt armor that appeared before the 1.0.3 update, when it was replaced by Jungle armor. The old design was later re-introduced, in 1.2, as Ancient Cobalt armor. It currently shares identical stats with Jungle armor, but differs in appearance. Furthermore, Jungle armor and Ancient Cobalt armor pieces can be mixed and matched while still providing their set bonus.
