Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 16 (3d8 + 3) necrotic damage.

Etherealness

The ghost enters the Ethereal Plane from Feyland, or vice versa. It is visible in Feyland while it is in the Border Ethereal, and vice versa, yet it can't affect or be affected by anything on the other plane.

Horrifying Visage

Each non-undead creature within 60 feet of the ghost that can see it must succeed on a DC 15 Wisdom saving throw or be frightened for 1 minute. If the save fails by 5 or more, the target also ages 1d6 × 10 years. A frightened target can repeat the saving throw at the end of each of its turns, ending the frightened condition on itself on a success. If a target's saving throw is successful or the effect ends for it, the target is immune to this ghost's Horrifying Visage for the next 24 hours. The aging effect can be reversed with a greater restoration spell, but only within 24 hours of it occurring.
