Lifesense 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.

Effect The spirit emits a brief pulse of void energy that deals 5d6 void damage to the triggering creature (DC 28 basic Reflex save).
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 20 feet, fly 40 feet
Melee Spectral Claw +24 (finesse, reach 20), Damage 2d12+8 void plus Drain Life

Reach is reduced to 10 feet if rune is disabled

Abyssal Spite (occult)

The spirit lashes out at a creature within 60 feet, dealing 2d12+8 mental damage (DC 30 basic Will save).

Drain Life (divine)

When the demoniac spirit damages a living creature with its spectral claw Strike, the spirit gains 10 temporary Hit Points and the target must succeed at a DC 30 Fortitude save or become Drained 1. Further damage dealt by the spirit increases the drained condition value by 1 on a failed save, to a maximum of drained 4.

Effect: Drain Life

Ritual Transformation

The spirit has been absorbing energy through the ritual so it can transform itself once Urxehl manifests. Once the total value of all of the drained conditions the spirit has inflicted with drain life reaches 3, it loses its incorporeal trait as its body becomes solid. The spirit loses all of its immunities and resistances, it gains 40 Temporary Hit Points, and its Strength bonus increases to +0.
