Mordenkainen's Lost Notebook
2-level Evocation
Choose a creature which can see and hear you within range. You set up painful vibrations within that creature. Starting this round, and at the beginning of each of the creature’s turns, the creature takes 1d4 points of thunder damage and is poisoned. The creature can use its action to make a Constitution saving throw; on a success, the damage and poisoned effect are negated for that turn, but the subject must continue to make saving throws on each of its turns for the duration. If a subject under the effect of painful echoes is affected by deafening blast or resonating agony (q.v.), the spells interact to create a cumulative effect. See the deafening blast and resonating agony spells for details.
