Special Traits

• Ethereal Sight. The spirit can see 60 feet into the Ethereal Plane when it is on the Material Plane, and vice versa.
• Incorporeal Movement. The spirit 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.

Actions

• Multiattack. The spirit can use its Horrifying Visage. It then attacks with its Blood-Chilling Touch.
• Blood-Chilling Touch. Melee Spell Attack: +7 to hit, reach 5 ft., one target. Hit: 21 (5d6 + 4) necrotic damage, or 28 (7d6 + 4) necrotic damage, if the target is frightened.
• Etherealness. The spirit enters the Ethereal Plane from the Material Plane, or vice versa. It is visible on the Material Plane 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. Creatures within 60 feet of the spirit, other than undead, that can see it must succeed on a DC 15 Wisdom saving throw, or be frightened for 1 minute. While frightened in this way, a target has disadvantage on saving throws against possession by the spirit. 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 spirit’s Horrifying Visage for the next 24 hours.
• Possession (Recharge 6). One humanoid, that the spirit can see within 5 feet of it, must succeed on a DC 15 Charisma saving throw or be possessed by the spirit; the spirit then disappears, and the target is incapacitated and loses control of its body. The spirit now controls the body, but the target is still aware of its surroundings. The spirit can’t be targeted by any attack, spell, or other effect, except ones that turn undead, and it retains its alignment, Intelligence, Wisdom, Charisma, and immunity to being charmed and frightened. It otherwise uses the possessed target’s statistics, but doesn’t gain access to the target’s knowledge, class features, or proficiencies. The possession lasts until the body drops to 0 hit points or takes an amount of radiant damage from a single hit equal to the spirit’s current hit points. The possession also ends if the spirit is turned, or forced out, by a dispel evil and good spell or similar effect, or the spirit ends the effect as a bonus action. When the possession ends, the spirit reappears in an unoccupied space within 5 feet of the possessed creature. The target is immune to this spirit’s Possession for 24 hours after succeeding on the saving throw, or after the possession ends.
