Vesper's Arcane Tethers

The mind of your awakened spellbook is summoned onto a surface on the battlefield. Choose up to four creatures in a 30-foot-radius sphere centered on that point. Each target must make a Strength Saving Throw as arcane tethers shoot out from the awakened mind, they take 4d6 piercing damage and on a fail they are pulled towards the book, and takes 4d6 force damage as a small 10-foot radius explosion goes off. You cannot force a creature to fall more than 30 feet.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher you may target one more creature for each level above 5th, the fire damage and the force damage increases by 1d6 for each slot level above 5th.
