The Black Chalice

A downloadable one-page tarot ttrpg

Will you take the bane with the boon?

You are invited to a seance by The Bone Chalice where your petitioner will risk all for supernatural favours.

The Black Chalice is a ttrpg for up to 6 players, as you create Petitioners seeking supernatural intervention and Spirits looking to sustain themselves in the unending afterlife.

A tarot deck of your choice will be your mechanic, bringing your Petitioners and Spirits to life, so to speak.  Taking turns, your Petitioner will make an offering, and through this sacrifice, request a boon of the Spirit. But every boom comes with a bane, a larger cost beyond the cards. Do you want the boon enough to take the bane? 

You never know, your Petitioner may walk away from the evening with most of what they wanted. But at what cost? 

The trifold layout gives you everything you need to play. This game can be played in-person with a single tarot desk or each with their own.
