You attempt inflict a mental illusion trick a creature into thinking it is poisoned. The creature takes 2d6 psychic damage and must make a Wisdom saving throw or become poisoned. While poisoned this way, at the start of their turn, they take 2d6 psychic damage. This affects creatures that are normally immune to the poisoned condition, but creatures that are immune to psychic damage are unaffected. The creature can repeat the saving throw at the end of their turn, ending the poisoned condition on a success.
