Mask of Violence. The worm fiend twists its face into a terrible rictus of hatred and violence. Each creature within 10 feet of the worm fiend must succeed on a DC 10 Charisma saving throw or be frightened for 1 minute. A frightened target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a target’s saving throw is successful or the effect ends for it, the target is immune to all worm fiend's Mask of Violence for the next 24 hours.
