Duel of Pride

As an action, you can attempt to initiate a duel with any humanoid within 30ft. The target must make a DC 30 WIS Saving Throw. On a fail, a 20ft radius globe appears centered on the ground between the two duelists. All other creatures are expelled to the outside of the globe to the closest open 5ft square. The globe is under the effects of Wall of Force and Globe of Invulnerability as if cast at 9th level and lasts for 10 minutes or until one of the duelists is dead.
