Necromancy Can Be Good
Ethereal Sight. The hauntling can see 60 feet into the Ethereal Plane when they are on the Material Plane, and vice versa. Incorporeal Movement. The hauntling can move through other creatures and objects as if they were dicult terrain. The hauntling takes 1 force damage if they end their turn inside an object.
Etherealness. The hauntling enters the Ethereal Plane from the Material Plane, or vice versa. They are visible on the Material Plane while they are in the Border Ethereal, and vice versa, yet they can't aect or be aected by anything on the other plane. Possession (1/Day). The hauntling can attempt possess a beast. If the target has a CR of 0, the hauntling disappears, the target is incapacitated, and it loses control of its body. The hauntling now controls the body. They can't be targeted by any attack, spell or other eect, except eects that turn undead. They retain their alignment, Intelligence, Wisdom, and Charisma scores, and their immunity to being charmed or frightened. They otherwise use the possessed target's statistics, but don't gain access to the target's knowledge or prociencies. The possession lasts until the body drops to 0 hit points, the hauntling ends it as a bonus action, or the hauntling is turned or forced out by an eect like a dispel evil and good spell. When the possession ends, the hauntling reappears in an unoccupied space within 5 feet of the body. The target is immune to this hauntling's Possession for 24 hours after the possession ends.
Veil (3/Day). When an adjacent creature is the target of an attack, the hauntling can use their reaction to quickly hide themself and the target (if they are willing) into the ethereal plane, preventing any damage. They are visible on the Material Plane while they are in the Border Ethereal, yet they can't aect or be aected by anything on the other plane. The hauntling must use their next turn to return them to unoccupied spaces within 10 feet of (or nearest to) the spaces they vanished from.
