You afflict a nearby creature with a pain so unbearable that its agony, aggravated by magic, is enough to damage the bystanders. The target must make a Constitution saving throw. It takes 8d8 necrotic damage on a failed save, or half as much damage on a successful one. The first target’s agony then magically affects up to three creatures, each of which must be within 30 feet of the first target and must be able to see and hear it. The secondary targets must make a Wisdom saving throw. A secondary target takes 6d8 psychic damage on a failed save, or half as much damage on a successful one. This saving throw is made with disadvantage if the damage was enough to reduce the primary target to 0 hit points of fewer. This spell has no effect on undead or constructs.
