Tasha’s Unfortunate Shart

You point at a creature within range and force their digestive system to accelerate at magical speeds. The target must succeed on a Constitution saving throw. On a failure, the creature takes 2d6 poison damage and is Poisoned until the end of its next turn as it suffers a "wardrobe malfunction."

While poisoned this way, the creature has disadvantage on Stealth checks (due to the smell/squelching) and Charisma checks. If the creature is wearing heavy armor, it takes an additional 1d6 psychic damage from pure embarrassment.
