Song of Hastur

3rd-level abjuration

Casting Time: 1 action

Range: 150 feet

Components: V

Duration: Instantaneous

You hum a melody that creeps into a creature’s mind and drains its magical power. A target creature that you can see must make a saving throw using its spellcasting ability.

On a failed save, the target loses its highest-level spell slot. On a successful save, the target loses its highest-level spell slot of 3rd level or lower. A creature with multiple spellcasting abilities uses its highest one, or one chosen randomly if there is a tie. A creature that has no spellcasting ability or no spell slots takes 4d6 psychic damage but suffers no other effect.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, then on a successful save, the target instead expends its highest-level spell slot of an equal or lower level to the slot you expend to cast Song of Hastur.
