Ghost Commoner (BB)

A ghost can stray no more than 120 feet from where it was killed or the place it haunts. Some are bound to items or creatures that were special to them rather than a location.

A ghost has no body and can pass through physical objects, though it can't end its turn inside one. Most checks that use Strength and require a body, such as Grapple, don't work against a ghost, and a ghost can't attempt such checks.

Setting right the injustice that led to the ghost's death allows it to move on to the afterlife. Otherwise, when destroyed, the ghost re-forms after within the location it's bound to, fully healed.

Each living creature within 30-foot area who hears the ghost must attempt a DC 21 will save. On a failure, a creature gains the Frightened 2 condition (or Frightened 3 on a critical failure).

On a success, a creature can't be affected by this ghost's Frightful Moan for 1 minute.
