Site Bound

A typical ghost can stray only a short distance from where it was killed or the place it haunts. A typical limit is 120 feet. Some ghosts are instead bound to a room, building, item, or creature that was special to it rather than a location.

The spirit hound returns with the Caretaker.

Void Healing

A creature with void healing draws health from void energy rather than vitality energy. It is damaged by vitality damage and is not healed by vitality healing effects. It does not take void damage, and it is healed by void effects that heal undead.

Speed fly 30 feet
Melee Ghostly Jaws +10 (agile, finesse, magical), Damage 1d4+1 void
Frightful Moan (auditory, divine, emotion, fear, mental)

The spirit hound howls, forcing each living creature within 30 feet to attempt a DC 15 Will save. On a failure, the creature becomes Frightened 2 (Frightened 3 on a critical failure). On a success, the creature is temporarily immune to this hound's frightful moan for 1 minute.

Pack Attack

The spirit hound's Strikes deal 1d4 extra damage to creatures within the reach of at least two of its allies.
