The Cobalt Hat can be crafted with 10 Cobalt Bars at an Iron Anvil/Lead Anvil. Wearing this as part of the Cobalt Armor set grants a reduction in mana usage. It is considered to be the weakest Hardmode Tier armor.
- It appears to be a traditional Japanese hat known as a Kasa, or in combat situations, Jingasa. The Cobalt Naginata is another reference to Japanese Samurai.
- No longer a component in Hallowed Headgear.
- Added to the game.
