The Brackish Flask is a Hardmode bomb (Although can be obtained Pre-Hardmode), that is dropped by the Leviathan and Anahita. When used, it is thrown from the player at a medium velocity and with a heavy gravity-affected arc. Once it collides with an object, it shatters and releases 8 seawater blasts in all directions, which then explode into damaging clouds after traveling a short distance or impacting enemies or tiles. All of these projectiles deal 50% of the flask's damage, and inflict the Poisoned and Venom debuffs.

Performing a stealth strike with the Brackish Flask causes it to deal 85% damage and release a large brackish spear spike upwards from the point of impact, that acts similarly to Atlantis, going through walls and enemies dealing 85% damage. Additionally, other projectiles spawned by the weapon will deal 42.5% damage.

Its best modifier is Flawless.


  • Due to the fact that the mist projectiles are released in all directions, several of them will often immediately explode against the area that the flask initially impacted.


  • Brackish is a term used to describe water that is a mix between fresh and salty.

The Brackish Flask being thrown at a group of Target Dummies, with projectiles being released to hit other Target Dummies.
