Temporal Vortex

You cast a spell that speeds up time in your proximity. Everything within 20 feet of you (including you) when the spell is cast will undergo up to an hour of effective time comparative to an instant in the outside world. A shimmering pearlescent globe delineates the edge of the effect. Any spell cast within this area during this time ends the Temporal Vortex. Ongoing spells and magical effects are "paused" within the area for the duration unless they were created by a deity or an artifact. Any creature or item leaving the area of effect immediately ends the spell. Anything inside the area of effect cannot affect anything outside it, and vice-versa, for the duration of the spell.
