You clutch your hand into a fist and magically grip the throat of one creature that you can see within range. The target takes 4d6 force damage and must make a Strength saving throw. On a failed saving throw, the target becomes restrained until the spell ends.

While restrained by this spell, the target takes 4d6 force damage at the start of each of its turns. It cannot speak, provide verbal components, or breathe, and it cannot use breath-based abilities. If the target must breathe, it has disadvantage on concentration checks, and you add your spellcasting ability modifier to the DC for concentration checks caused by this spell.

A restrained target can use an action on its turn to make a Strength saving throw against the spell, escaping the effect on a successful saving throw.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, you can target one additional creature for each slot level above 4th. The creatures must be within 30 feet of each other when you target them.
