Time Stop (Revised)

You briefly stop the flow of time for everyone but yourself. No time passes for other creatures. During this moment in time, you regain your action, bonus action, and movement. Creatures stopped in time cannot take reactions and are not aware of anything that occurs within the stopped time. You regain your reaction, but if it is not spent before time resumes it disappears.

If you use this reaction when another creature casts this spell, you both gain the benefits and move in initiative order to decide who moves first. You and the other caster are considered not stopped in time for the purposes of reactions and awareness.
