Master of Two worlds
As with all the steps, sometimes they are clearly separate from each other and other times they are intertwined and flow directly into each other as part of the same scene. Magic Flight, Crossing the return Threshold and Master of the two worlds can be one large block.
By the end of this stage, the hero now has proven he ability to effortlessly pass back and forth between the two worlds.
Increase the stakes at this stage by putting a ticking time bomb of some sort about to go off. Make the enemy confident and seemingly have the advantage over the Hero for the longest possible time.
In Aliens Ripley has combined her loader lifter skills with her warrior protector skills and fights the Alien Queen “Get away from her you bitch!”

How to use this in your writing
This is the final confrontation; don’t have anything left in the tank at the end of this battle.
Make sure everything is resolved with no loose ends.
Add to the desperation by considering the location, put your hero with his back against the wall so he has no place to run, if he fails he can’t escape, he will die. Or the reverse applies and locate the battle on the enemies home ground where he has the advantage.
Give the hero some witnesses to this action.
