Martillo de cobalto

• Hammer and Anvil - If the player has [Yunqueduela] , firing the Cobalt Hammer's charge attack also sends out anvils in all directions.
• Nailed It! - If the player has [Pistola de clavos] , its nails deal triple damage.

• This gun is a reference to the streamers Cobalt Streak and Richard_Hammer, who before the release of Enter the Gungeon were known for playing The Binding of Isaac , another shooter rogue-like. They were also known to "break" games or exploit game mechanics to a ridiculous, often beneficial degree. The item description refers to their several day long stream leading up to Enter the Gungeon's release, where the two would take turns streaming and sleeping.
• This may also be a reference to the final level of Cave Story, where the protagonist ties his passed out companion to his back.
• The thunder effect and sound are a reference to Mjolnir, the hammer used by the Norse God of Thunder, Thor.
• When firing a charged shot with an item that increases amount of bullets fired (example: [Perdigones] ) the ammo usage per shot also increases.
• When firing a charged shot, consumes one ammo from the current magazine, but costs 3 ammo.
