Temporal Divergence

You disrupt the flow of time and create a translucent, spherical demiplane with a radius up to 30 feet centered on a point you choose. Time within this demiplane passes significantly faster than time outside, allowing you to experience 24hours of time while those outside only experience 1 hour. To those inside the sphere, the outside world appears nearly motionless and sluggish, while to those outside, the inside appears blurred and impossible to keep up with. 

Creatures and objects can pass into and out of the demiplane, but no spell or magical effect can pass into or out from the demiplane. In combat, creatures on the outside of the sphere can only take their turns every 24 rounds. 

You can end the spell early by using an action to dismiss it.
