Antimagic Restraints

You attempt to block a creature that you can see within range from the magical energy that suffuses the multiverse. The target must succeed on a Constitution saving throw or be blocked from their magic. A creature concentrating on a spell has advantage on this save. While blocked, the target can't cast spells, concentration on active spells ends, and magical effects originating from the target are suppressed. If the target attempts to cast a spell, it fails, but the spell slot is not consumed. At the end of each of its turns, the target can make another Constitution saving throw. On a successful save, the spell ends on the target.

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.
