Temporal Bubble

You create a translucent, spherical demiplane with a radius up to 50 feet centered on a point you choose within range. Time within this demiplane passes significantly faster than time outside, allowing you to experience 24 hours while those outside the bubble only experience 1 hour. To those inside the sphere, the outside world appears nearly motionless and sluggish, while to those outside the bubble the inside of the sphere appears blurred and spastic. When it is cast, the spell emits a short, high-pitched cacophony audible out to 1 mile. 

Creatures and objects can pass into and out of the demiplane, but no spell or magical effect created on one side of it can affect the other side. In combat, creatures on the outside of the sphere can only take their turns every 24 rounds, starting with the first round of combat.

You can use an action to dismiss the spell
