You create an area of warding about you to protect you and your allies. The area is a 60 foot cylinder with a 10 foot radius and can hold a number of medium or smaller creatures equal to your spellcasting ability modifier. The area must be affixed to a solid surface. A creature within the area when the spell is cast can move in an out of the barrier without issue. Other creatures who attempt to enter the area simply cannot enter the area by nonmagical means. A creature who attempts to enter the area by teleportation or planar travel must succeed a Charisma saving throw. On a failed save, their attempt simply fails. This has no effect on undead or constructs.
