Ethereal Sight. The ghost can see 60 feet into the Ethereal Plane when it is on the Material Plane, and vice versa.
Incorporeal Movement. The ghost can move through other creatures and objects as if they were difficult terrain.
It takes 5 1d10 force damage if it ends its turn inside an object.
Withering Touch. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 16 2d12+3 necrotic damage.
Etherealness. The ghost enters the Ethereal Plane from the Material Plane or vice versa.
While it is in the Ethereal plane, it can't affect or be affected by anything on the Material plane and vice versa.
Spooky Attempt. One non-undead creature the ghost can see within 60 feet must succeed on a DC 13 WIS save or be frightened for 1 minute.
If a friendly creature succeeds by 5 or more, they must feign being frightened or the ghost becomes depressed.
A frightened target can repeat the saving throw at the end of each of its turns, ending the condition 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 Spooky Attempt for the next hour.
