Cobalt Ore

Cobalt Ore is an ore from 1.1 update. It will likely be used to craft Cobalt armor, Cobalt Drill, Cobalt Chainsaw, Cobalt Brick and Cobalt Brick Wall.

Cobalt equipment is, as the name would suggest, obviously blue. The particular thematic it entails is a Japanese one, it's spear being a naginata and the various head gears resembling japanese headdresses.

The ore will not appear in the world until the player destroys a Demon Altar with a Pwnhammer. This will "bless" the world with deposits of either Cobalt Ore, Mythril Ore, or Adamantite Ore. These ores will then be found randomly like any other.

Cobalt Ore is colored deep-blue and seems to be found at the Cavern level.
