Ampoule of the Abyssal Deep

Description. 

The item is fasioned out of beautiful sea glass and rainbow shell for a cap. At the very tip of the cap is a thin and sharp metal protrusion that is chilllingly cold to the touch. When one holds the Ampoule, if they aren't attuned to it, they hear maddening whispers in their mind, wracking them with mental pain. If they are bound to the weapon, they feel connected to it like it is an actual part of them, a vestige that they can use like a third eye.
