Pale Sovereign

Demesne Confinement (curse, occult) — A pale sovereign is tied to their demesne, a territory of a 5-mile radius surrounding their home estate. They can't leave their demesne of their own accord. A pale sovereign taken from their demesne can't use any of their innate spells or rituals and gradually withers over the course of a week, turning to dust if they don't return before 7 days have passed.

Sense Visitors (detection, occult) — A pale sovereign automatically knows when a creature enters or leaves their demesne, though this doesn't give them precise knowledge of the creature's location.

Constant Spells — A constant spell affects the monster without the monster needing to cast it, and its duration is unlimited. If a constant spell gets counteracted, the monster can reactivate it by spending the normal spellcasting actions the spell requires.

-2 to All Saves vs. Curses —

Aura of Charm (aura, emotion, incapacitation, mental, occult) — 80 feet. The aura of a pale sovereign is beguiling and inviting, affecting creatures beginning their turns within it with an 8th-rank Charm (DC 39 Will save). A creature that fails its Will save perceives the pale sovereign as they were in life, not their current undead form. A creature that succeeds at its save is then temporarily immune to that pale sovereign's aura for 24 hours.

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.

Curse of Eternal Sleep (curse, incapacitation, mental, occult, sleep) — The pale sovereign touches an adjacent living creature to send it into an endless slumber. The target must attempt a DC 39 Will save.

Critical Success The target is unaffected and is temporarily immune for 24 hours.

Success The target becomes drowsy and is Slowed 1 for 1 minute.

Failure The target falls Unconscious, though it doesn't fall Prone or release what it's holding. It can't awaken with a successful Perception check, though dealing any amount of damage to the creature breaks the slumber. If it's still unconscious after 1 hour, it awakens.

Critical Failure The target falls unconscious permanently, falling prone, and can't be awoken as long as the curse remains.

Siphon Vitality (occult, void) — The pale sovereign siphons the life force from creatures around them. All living creatures in a 30-foot emanation take 6d8 void damage (DC 39 Fortitude). The pale sovereign regains HP equal to the highest damage a single creature took from this effect.
