Tollvych

If the heroes destroy Dwandek (even if only temporarily, before destroying his soul cage as well), the cathedral's hold over Tollvych's soul loosens; the next time the heroes enter this room (or 24 hours later), his ghost rises one last time from his remains with a sigh, and then moves into the afterlife. When a ghost is destroyed, it re-forms after 2d4 days within the location it's bound to, fully healed. A ghost can be permanently destroyed only if someone determines the reason for its existence and sets right whatever prevents the spirit from resting.

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.

Tollvych cries out in pain as his body twists and grinds into horrific, distorted shapes. All creatures within a 30-foot emanation take 16d6 bludgeoning damage (DC 36 reflex save) as the sound of the Bone-Shattering Cry shakes and shatters their own bones. Tollvych can't use Bone-Shattering Cry for 1d4 rounds.

Tollvych laments his fate, forcing each living creature within 30-foot emanation to attempt a DC 36 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 Tollvych's frightful moan for 1 minute.
