Ectopsychic Echo

Generate a rebounding wave of psychic feedback between you and an ally within range, dealing painful psychic damage to anyone caught in between. Creatures in the line between you and your target must make a Wisdom saving throw, suffering 2d10 psychic damage on a failed save, or half as much on a success.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d10 for each slot level above 2nd.
