The Cobalt Shield is an accessory that negates all knockback when the player is damaged, and grants 1 defense. It is found in Golden Chests in the Dungeon. It is useful for fighting enemies near large drops, lava, or when using Rocket Boots as it then becomes possible to fly out of caves or Chasms without being knocked back. It can be combined with an Obsidian Skull to make the Obsidian Shield at a Tinkerer's Workshop.
- As the Cobalt Shield removes knockback, it can be used in conjunction with Hermes Boots to run through enemies without losing speed.
- Despite its name, the Cobalt Shield is not part of the Cobalt Armor set and cannot be made with cobalt bars.
- It must be equipped in order to have any effect on the player.
- This accessory is useful when using the Hellstone/Meteorite tactic against Skeletron Prime
