Kylix of Dionysus

The Kylix of Dionysus, does not appear in real world Greek mythology.
However, in world the Kylix of Dionysus is an artefact synonymous with the diety Dionysus, this bowl is present at all his wildest parties, bringing forth merriment and joy, but to people who have wronged Dionysus drinking from it will induce extremely potent madness, that until the diety sees fit, it seemingly has no cure. In parts of the world it is an object of fear, others its a symbol of good times. Similarly to the God himself you can't be quite sure what you get.
