Abyssal pull

You point your finger and force a hole in the weave, causing a small rift that pulls in everything around it. Creatures and objects within a 15 ft sphere are dragged to it's center. to not be pulled into the rifts center, creatures need to make a strength saving throw, but creatures can choose to automatically fail this saving throw. Creatures have disadvantage on the saving throw if they are on difficult terrain. If a creature starts it's turn in the center of the rift, it takes 2d4 force damage. While in the rift, creatures are restrained. You can close the rift early as a bonus action.

This spells area of effect increases by 5 ft at 5th level (20 ft), 10 ft at 11th level (30ft), and 20 ft at 17th level (50ft).
