Claw. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 15 (3d8 + 2) slashing damage.

Terrifying Mask. Each non-Undead creature within 60 feet of the dissimortuum that can see it must succeed on a DC 15 Wisdom saving throw or be frightened for 1 minute.

If a target's saving throw is successful or the effect ends for it, the target becomes immune to the dissimortuum's Terrifying Mask for the next 24 hours.
