Labyrinthine Howl 2014

You let loose the howl of a ravenous beast, causing each enemy within range that can hear you to make a Wisdom saving throw. On a failed save, a creature believes it has been transported into a labyrinth and is under attack by savage beasts. An affected creature must choose either to face the beasts or to curl into a ball for protection. A creature that faces the beasts takes 7d8 psychic damage, and then the spell ends on it. A creature that curls into a ball falls prone and is stunned until the end of your next turn.

When you cast this spell using a spell slot of 6th level or higher, the damage increases by 2d8 for each slot level above 5th.
