Anti-Magic Blast

You unleash anti-magic power at an enemy. Make a ranged spell attack against a creature within range. On a hit, that creature must make a WIS saving throw, taking 3d10 psychic damage on a failed save, or half as much on a successful save. Additionally, if they fail their saving throw they become unable to cast spells of 6th level or lower for the duration.

At Higher Levels. When you cast this spell using a spell slot of 7th or higher it deals 1d10 more damage for each slot level above 6th.
