My group was in this cottage gathering clues when someone kicked open the door while wielding a battle axe. I as a cleric reacted to this by using my action in order to make the now open door slam shut on his face pushing him outside using thaumaturgythaumaturgy:
You instantaneously cause an unlocked door or window to fly open or slam shut.
So what happens to the guy who had kicked the door?
The guy was standing right at the entrance breathing heavily and I won initiative.
