Scroll of Fiend Protection

Use an action to read the scroll: you are enclosed in an invisible barrier that extends from you to form a 5-foot-radius, 10-foot-high cylinder. For five minutes, this barrier prevents fiends from entering or affecting anything within the cylinder.
The cylinder moves with you and remains centered on you. If you move in a way that would put a fiend inside the barrier, the effect ends.
A fiend can attempt to overcome the barrier by using an action to make a DC 15 Charisma check.
