Site Bound

Diggen Thrune's ghost cannot leave the keep while Nashaxian still watches it. If Nashaxian is rendered unable to watch over him (such as if the PCs bind the devil to the keep), then Diggen can leave the keep. Still, his soul cannot pass on to the afterlife until he fulfills the terms of his contract.

Object Habitation

Diggen Thrune can occupy a magical object.

Diggen can't be targeted or harmed while occupying an object, but he can only exit the object with the assistance of a mortal in possession of the object.

Rejuvenation (divine)

Setting Diggen free from his contractual obligations with Nashaxian allows him to move on to the afterlife.

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 25 feet

Melee Ghostly Hand +13 (agile, finesse, magical), Damage 2d6+2 void

Frightful Moan (auditory, divine, emotion, fear, mental)

Diggen Thrune laments his fate, forcing each living creature within 30 feet to attempt a DC 21 Will save. On a failure, a creature becomes Frightened 2 (or Frightened 3 on a critical failure). On a success, a creature is temporarily immune to this ghost's frightful moan for 1 minute.
