Chronometric State of Acceleration

A bright orange light emanates from your hands and accelerates time for targets caught in a 60ft long by 20ft wide cylinder fires out from where you're directing. Each creature in the cylinder must make a Constitution saving throw against your Spell save DC. A target takes force damage equal to 3d4 + 10% of their missing health on a failed save, or negate the missing health percentile damage on a successful one, taking only the dice roll damage instead. 

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the force damage increases by 1d4 + 10% maximum health for every spell slot level above 3rd. When casting this spell at 6th level or higher, and the target fails their saving throw, the target takes 10% missing health force damage at the end of each subsequent turn, where they can repeat their saving throw to end this effect. This damage over time does not increase at higher levels.
