Waking Nightmare Acid

You can apply a dose of this acid to a weapon with the Use an Object action. The next time this weapon deals damage, the creature must make a Wisdom saving throw. If the creature fails, it is frightened and takes 1d6 psychic damage at the start of each of its turns for the next minute. The creature can repeat this saving throw at the end of each of its turns, ending the effect on a success.
