Time Varying Magnetic Field

A time varying magnetic field is induced in a 20-foot square starting from a point within range. For the duration, the field creates eddy currents in all closed loops, plates, etc which induce a moment that pulls all down to the ground. The ground in the area can be regarded as difficult terrain.

A creature in the area when you cast the spell must succeed on a Strength saving throw or be restrained by the magnetic field until the spell ends. A creature restrained by the field can use its action to make a Strength check against your spell save DC. On a success, it frees itself.

When the spell ends, the field dissipates.
