Arresting Sphere

You slow the flow of time to a crawl within a sphere. Target a point you can see within range. All objects and creatures within a 30 foot radius sphere, weighing up to 3000 pounds, are suspended in time. Any unwilling creatures must make a Strength saving throw. If they succeed, they can continue to move as normal, but cannot interact with the objects contained within the sphere. On a failed save, they are suspended in time and cannot be targeted by any attacks or damaging effects that would violate the continuity of their frozen time. For the duration, or until dispelled, any additional objects that enter the sphere are also suspended, up to the weight limit. In addition, any creatures that enter the spell must also make the Strength saving throw. Once the spell ends, all objects resume movement as normal, and their momentum is conserved from when they entered the sphere. 

Any objects that go over the weight capacity of the sphere are unaffected and fall or move as normal. 

At Higher Levels: When cast at a spell level of 6th level or above, the amount of weight that the sphere can contain increases by 500 pounds per spell level
