Tetherith's Ghastly Thorn Rain

This spell creates a rain of twisted spectral thorns that sprouts from your ranged weapon or ammunition. In addition to the normal effect of the attack, the target of the attack and each creature within 5 feet of it must make a wisdom saving throw. A creature takes 2d10 psychic damage and is frightened for the duration on a failed save, or half as much damage on a successful one. 

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