The Cobalt Sword can be crafted at an iron anvil with 10 Cobalt Bars. It is considered to be one of the weaker hardmode Tier weapons.
- Minus the generated light, this weapon could be considered a slower, more powerful, Hard Mode version of the Muramasa.
- This weapon, with a knockback buff, can be used for the entirety of Hardmode, until Excalibur is obtained, due to its speed and autoswing.
- The weapon bears a resemblance to a weapon called a dai katana. The katana has the handle and guard, but the blade is enlarged to twice the normal thickness. This type of katana is not often seen, being mostly harder to wield. The weapon also bears a resemblance to Muramasa.
- Damage increased from 34 to 39.
- Added to the game.
