Damage/Effect
Poisoned
You present the digusting items before the target in an attempt to convince them that they are feeling very queazy. The target must make an Intelligence saving throw. On a failure, the target becomes poisoned for the duration of the spell. This spell ignores any resistance or immunity to the poisoned condition as there is no actual poison affecting the target; it is only their belief that they are poisoned that affects them. The target may make an Intelligence saving throw at the end of their turn. On a success, the spell ends.
At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, you can target one additional creature for each slot level above 4th.
* - (a small bag of mushrooms, and a vial of sour milk)
I think it'd be interesting if creatures that are immune to being poisoned gain advantage on the throw, as it would be hard to fool a creature that they're something they can't be while resistance is completely bypassed
