Sorvinaesen

Lifesense (Imprecise) 60 feet — Lifesense allows a monster to sense the vital essence of living and undead creatures within the listed range. The sense can distinguish between the vitality energy animating living creatures and the void energy animating undead creatures, much as sight distinguishes colors.

Catch Rock —

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.

Font of Death (divine, void) — The tomb giant turns the spiritual tide on a creature that has just died, temporarily transforming it into a volatile vessel of void energy. The tomb giant touches a creature that died in the past 24 hours, infusing its flesh and bone with void energy. Once during the next hour, the tomb giant can spend a single action (from any distance) to release this void energy from the corpse in an explosion that deals 10d12 void damage energy in a 15-foot burst (DC 36 Fortitude save); if not released before the end of the hour, the energy dissipates harmlessly. The tomb giant can't use Font of Death while a previous corpse remains infused.

Impart Doom (divine) — A creature hit by Sorvinaesen's claw Strike, or one who critically fails a save from one of Sorvinaesen's spells, becomes Doomed 1.

Throw Rock — The monster picks up a rock within reach or retrieves a stowed rock and throws it, making a ranged Strike.

Visions of Death — Sorvinaesen's Strikes deal an additional 2d10 mental damage to doomed creatures as visions of their impending deaths fill their minds.
