Brackish Flask

The Brackish Flask is a Hardmode bomb, 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 release a large brackish spear spike upwards from the point of impact, that acts similarly to Atlantis, going through walls and enemies.
