Antimagic Prison

You create a invisible 10 by 10 ft square prison of antimagic which surrounds the target and any creatures inside. This area is divorced from the magical energy that suffuses the multiverse. Within the prison, the target sees only whiteness, spells can't be cast, summoned creatures disappear, and even magic items become mundane. Until the spell ends the target/s are trapped inside the prison as if it was solid. Any creatures who are in the prison on the end of their turn must succeed a DC 15 intelligence saving through or be restrained for the duration.

Spells and other magical effects, except those created by an artifact or a deity, are suppressed in the prison. A slot expended to cast a suppressed spell is consumed. While an effect is suppressed, it doesn't function, but the time it spends suppressed counts against its duration. If a damaging spell outside the area of the prison is cast on a target inside the prison spell has disadvantage, all other spells fail instantly and are treated as if cast on a antimagic field.
