Gray justice has found use as an apparent truth serum since it makes victims more susceptible to interrogation. Additionally, it causes side effects such as lethargy, confusion, and nausea.
Some administer it to prisoners before their execution to make them publicly admit their crimes. The grim truth of the poison is damning, however. Gray justice is no truth serum, but instead compels its victims to say whatever they think will please those around them. Each round a victim takes Wisdom damage from the poison, he answers any questions in the affirmative, agreeing to the best of his ability and even lying to confirm whatever he assumes the questioner wants to hear. If questioned by multiple people, the victim might contradict himself. If asked questions without an affirmative response or leading answer, the victim does not need to respond.
