Temporal Sinkhole

You create a momentary, almost imaginary mass of magic that is so heavy it bends the fabric of spacetime around it. You choose a point within range and this mass travels there, creating a 10 foot wide line along its path, and then it collapses in a 15 foot radius sphere centered on the point you chose. All creatures within the line and the sphere’s area make a Constitution saving throw, and all creatures within the line *and* the sphere make this saving throw at disadvantage. On a failed saving throw, each creature takes 3d8 Force damage and is pulled 5 feet towards the center of the line and/or the sphere, or half as much and not pulled on a successful save, and the area of the spell is considered difficult terrain for 1d4 rounds. Within the area of this spell, non-magical objects that aren’t being worn or carried and structures are warped to begin to coil around its center at random directions and lengths, like the effect a Black Hole has, and as they get closer to where the center of the mass was, the older it gets, even withering, rusting, or becoming crusted. 

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, this spell deals an extra 1d8 of damage for each slot level above 1st.
