Anchor Howl

You unleash a resonant, commanding howl that weighs down your foes' resolve. Each enemy creature within a 30-foot radius of you must make a Charisma saving throw. On a failed save, a creature's speed is reduced by half until the end of your next turn.

At Higher Levels:
When you cast this spell using a spell slot of 3rd level or higher, the radius increases by 10 feet for each slot level above 2nd.
