Warding

You set a magical barrier against unwanted intrusion. Choose an area that is no larger than a 20-foot cube originating from you. Any creature that attempts to enter the area must make a Wisdom saving throw against your spell save DC. On a failed save, the creature cannot enter the space for the duration.  When you cast the spell, you can designate creatures that don't need to make a saving throw to enter. You must be inside the chosen space or the spell ends.
