Potion of Delusion
Property [Consumable]: As an action, you drink the potion. You believe you have consumed another potion and behave as though affected by that potion for as long as that effect normally lasts, until something happens to reveal the truth, or until you complete a long rest. For example, if the delusion is of a potion of healing, you believe you have healed. If the delusion is of a potion of flying, you might skip along the ground or leap from a rooftop in the belief that you can fly.
This potion appears to be another sort of potion, and it tastes and smells just like that potion. Sampling produces a sensation that mimics that of the other potion. Drinking the potion causes a wave of bliss to ripple through the imbiber.
