Time in a Bottle

9th-level transmutation (temporal, clockwork)

Casting Time: 1 action
Range: Sight
Components: V
Duration: Concentration, up to 1 minute

You designate a spot within your sight. Time comes under your control in a 20-foot radius centered on that spot. You can freeze it, reverse it, or move it forward by as much as 1 minute as long as you maintain concentration. Nothing and no one, yourself included, can enter the field or affect what happens inside it. You can choose to end the effect at any moment as an action on your turn.
