This is the time stop spell but better.

You summon + scream ZA WARDO and stop the flow of time for everyone within 30 feet of where you cast it. You get 3 straight turns in a row. They fail any checks they might need to pass.  Any attacks you make automatically succeed. You get one extra turn, should you prematurely end ZA WARDO, however, this turn is like any other attack.

Note: On the d&d wiki there is an ability called ZA WARDO for the stand user subclasses The Star and The World (I did not create these) that stop time that are frankly better and overall more descriptive than my spell. Credit to however made those subclasses and as well as where else credit is due.
