By RAW you can end any effect with a duration of more than 1 round. Gravity got you down? IRON HEART SURGE can solve that. Pesky sunlight getting in your eyes? Poof, bye bye sun. Are you currently not an overdeity? IHS can do that too.When you use this maneuver, select one spell,
effect, or other condition currently
affecting you and with a duration of 1
or more rounds. That effect ends immediately."
