Cobalt Armor

Cobalt Armor was replaced by Jungle Armor in the 1.0.3 patch, as a name and graphic swap (everything else is equivalent). Pieces of the Cobalt Armor could not be crafted and instead was dropped randomly from Hornets in the Underground Jungle. Existing pieces of Cobalt Armor that players owned were converted to Jungle Armor when the patch was applied.

Future
Cobalt Armor may be re-released in the 1.1 update.
