Snark glares at the bottle for what seems like an eternity, each breath of his growing deeper and deeper with every second. With a final growl of his the bottle explodes in a rain of glass shards and some Powerade-bright fluid.

What remains of the spilled liquid evaporates into the air, and the glass reforms itself into a chalice. Liquid the consistency of blood yet the color of green tea drips into it seemingly out of nowhere, and Snark disappears with a squelch.
An incredibly odd potion. It smells like death and tastes the same, and gives you the ability to communicate and physically interact with the spirits of the passed whenever you please. But while doing so you will lose all control of your body, and any spirits you talk with will be able to puppet it in your place, trapping you outside until you can get it back. With this all in mind, will you drink it?
